Wire rope pulling hoist the seven notes

Wire rope pulling hoist is a simple structure, the use of heavy lever handle complete lifting,hoist equipment lowering, pulling, lifting tool calibration and other operations. Wire rope pulling hoist can not only do non-linear traction work, but you can easily select the appropriate cutting operating position, maneuverability and traction from the principals, easy to use. Here to introduce you to the seven wire rope pulling hoist Precautions

One must choose the appropriate size of the load hoist tonnage

2, the housing must be checked prior to use all screws are tight, not loose; toggle lever check whether the action of various normal; when running coordination, no abnormal noise or catching the handle can be pulled loose unloading, penetration wipe clean already supporting rope and wire rope clamp, and then pulled forward or backward Shouben handle,hoist and trolley depending on whether the action is normal.

3, with the provisions of models, specifications of wire rope to hoist securely fixed.

4 operations, other than those allowed by supporting instead of wire rope with rope; operation, the rope should be kept clean to prevent the adhesion of mud and oil into the machine, affecting the normal use or exacerbate clamp wear.

5, no need to increase the use of lubricants

6, shall be arbitrarily extended operating handle; operation should let the rest handle freedom follower, not jamming.

7, in exceptional circumstances, gourds used as loading  lift hoist  raised, the hoist from the weight should be reduced to nominal weight of 1/3.

Proper maintenance of wire rope pulling hoist tips

Wire rope pulling hoist lifting equipment is widely used one, there are lifting, pulling, tensioning three functions, high safety factor, long service life. Good maintenance methods help to prolong the life of lever  manual hoist .
So how to better maintain the wire rope pulling hoist, the following points for you, I hope for your help:


Wire rope pulling hoist maintenance

1, each job is completed, we must first wipe the loose end of the rope on the adhesion of mud,lift hoist dust or grease, loosen the jaw, out of wire rope, wire rope sequence will gather around the shelves, and wipe the length of wire rope, wire rope stored in dry place to prevent corrosion.

2 year deal at least four times a gourd maintenance treatment, such as diesel cleaning parts, and calcium-based grease lubrication.

3, when the internal movement poured into the mud, cement or other dirt, use a rinse, then clean diesel; cleaning, dry calcium-based grease on the grease; finally release the jaws,wire rope winch wipe with a clean cotton pliers mouth of grease and moisture.

4, when the jaws wear, carrying capacity is less than 80% of rated load, replace the jaw; when the wire rope diameter is reduced 10%, the rope should be replaced

Fans hoist bucket chain positioning mechanism

       Wind turbine that is dedicated  wire rope hoist  electric hoist, electric hoist with its unique and innovative wind turbine is designed to meet the needs of the wind power industry, here to introduce you to an important part of the fan hoist bucket chain positioning mechanism.
Wind power electric hoist bucket chain positioning mechanism to solve the prior art bucket easy tilt and other technical issues. Including setting up in the chain between the bucket and hoist bucket chain and can be fixed at the bottom of the fixed ramp hoist structure,wire rope winch electric hoist chain be able to access bucket chain. The positioning mechanism further includes a fixed structure or between the bucket and chain electric hoist and chain bucket bucket chain between and can prevent lateral tilting at work limit structure.
       Fans hoist bucket chain positioning mechanism of the main features:
       A simple structure, reasonable design, can effectively avoid the chain out of the bucket chain process, due to the uneven distribution chain bucket chain orientation caused the phenomenon.
       2, improve job stability electric  lift hoist,  chain bucket can effectively avoid the occurrence of tilt, ensuring smooth out the chain bucket chain.
       3, bucket positioning solid, reliable, and easy to implement.

Electric hoist motors appear unbalanced three-phase power causes

  Most electric hoist three-phase voltage is used,chain Block but the process of using some of the fault is due to current imbalance caused, then the motor appears unbalanced three-phase power What is the reason, how should we avoid such failure causes electric hoist it ?
       When the basic symmetrical three-phase power, the asynchronous motor at the rated voltage of the three-phase load current, any one phase and the average deviation of not greater than the average of 10%. Therefore, only the three-phase voltage imbalance is too large, or electric  lift hoist  motor itself in case there is a fault, the motor phase current imbalance will appear.load chain The possible reasons are:
       1, three-phase power supply voltage unbalance caused by electric hoist motor phase current imbalance.
       2, the motor windings shorted.
       3, the inner part of the stator winding coil reversed.
       4, the three-phase windings of the motor are not equal.
       5, the winding circuit.

Chain hoists accident prevention

chain Block consequences of the accident, personal injury, equipment, facilities, damage to the degree of risk hazard class II critical preventive measures
1 work should concentrate, to observe, to rational operator;
2 before each use to make the necessary checks;
3 chain hoists are complete and secure;
4 seriously study the working principle of chain hoists and handling precautions;

Buy electric hoist should be noted that six basic parameters

     The use of safety-critical electric lift hoist , electric hoist in addition to strictly consider buying gourd quality and after-sales service, but we need some basic knowledge of electric hoist is understood that in the time of purchase to facilitate our use of the environment according to their own choice suitable products, the following introduces you to buy electric hoist should be noted that six basic parameters:
1, Installation: hoist into electric trolley and fixed, fixed can be divided into fixed (A1) and lower fixed (A2), to choose according to the actual situation of the electric hoist installation.
2, I-beam hoist hook to the bottom center:chain block electric hoist purchase should pay attention to the spacing between the upper and lower hook, because in certain plant would hoist hook spacing specific requirements.
3, voltage: electric hoist Because in all walks inside, using the voltage is not the same, there are 380V 220V China industrial electricity consumption, and even 440V, 60HZ, 380V, 60HZ series of non-standard power supply.
4, motor power: Different electric hoist motors are not necessarily identical, the same 10t electric hoist motor is also possible that 13KW or 7.5KW.
5, the lifting speed: Average electric  rope hoist  lifting speed is divided into single-speed (8m/min) and dual-speed (8/0.8m/min) two kinds, generally no special requirements are often used in the case of single-speed electric hoist (ie CD1-type), if your condition requires heavy lifting required to pinpoint the course of the case, easy to use two-speed electric hoist (ie, MD1 model).
6, lifting height: electric hoist as a promotion tool, would lift height has strict requirements. So buy electric hoist, you should first select according to plant height of lifting height, the conventional lifting height has 6,9,12,18,24,30 m, special occasions, according to user requirements for non-standard design.

Electric hoist crane safety devices

 Electric  lift hoist  crane because of its simple structure, easy operation, low cost, machinery, chemicals, light industry, railways and other industries widely used. Because of this special cranes, ground operations often a person several roles, and also served as operations, company search, command tasks, there are many unsafe operating risks.
       In order to prevent the occurrence of this type of crane lifting injuries, GB6067-1985 "crane safety regulations" and other relevant national standards have to be electric hoist crane must have safety devices, such as limit switch, end stop, bumpers, safety braking devices. These security guards equipped to effectively improve the safety and reliability of electric hoist crane, but because of the design, manufacturing defect itself a variety of reasons, the current electric hoist crane inadequate security measures, according to the daily inspection experience found hoist crane in the wrong phase-phase protection, anti-broken shaft protection against electric  manual hoist  fall protection, buffer settings, etc. are still flawed or inadequate.
       Since using the three-phase asynchronous electric hoist crane conical brake motor as power plant, while the three-phase asynchronous motor rotation direction and the power supply phase sequence, and when the power supply phase sequence is changed, the motor rotation direction and the direction of the original operation Instead, press "down" button, spreader rise, and rise to the limit position limiter does not work, likely to cause accidents. Every year, this type of crane caused due to wrong phase crushed reel, hook group extrusion, wire rope pull off the accident. At present, China produced and widely used CD, MD electric hoist did not take the wrong phase-phase protection measures. To prevent the wrong phase injury accidents caused by lifting,wire rope winch electric hoist crane electrical control system added wrong phase-phase protection.

Import and export of engineering and hoisting machinery presented five characteristics

This year, the world is facing economic recession, countries hit by the financial storm environment, the country has implemented the macro-control policies, resulting in resource commodities and labor-intensive merchandise exports fall, but due to national infrastructure continuity and long-term, therefore mainly used for infrastructure construction projects and the demand for lifting a limited impact in the near future.
    Meanwhile, the world is facing increasing scarcity of non-renewable resources and food security strategic position valued economic environment, engineering and hoisting machinery in the development of mineral resources and the development of economic activities in the food industry will have its uses, so their needs have greater space for our engineering and  lift hoist  machinery import and export is facing rare opportunities for development, import and export trade has shown rapid growth. Engineering and hoisting machinery import and export features:
    1 Engineering and lifting the fifth consecutive year export growth rate higher than the growth rate of export of electromechanical products.
    Although our engineering and hoisting machinery import and export trade import and export of electromechanical products accounted for the proportion of low, about 2%, but the engineering and  hoist equipment  import and export of general trade, processing trade, lower proportion; most export products own brand and cost competitiveness; obtain national policy support, so construction and agricultural machinery with export base and high growth potential.
    (2) Engineering and lifting the fourth consecutive year trade surplus.
    Engineering and lifting import and export trade deficit before 2004 were started in 2005 to achieve a trade surplus and the trade surplus increased every year. Engineering and lifting a gradual increase product awareness, increase international market share year after year is a major factor in generating trade surpluses. Foreign-invested enterprises and enterprises to innovate products to replace imported products trade deficit into a trade surplus in recent years, another important factor.
    3 Engineering and lifting machinery manufacturers of spare parts for global sourcing.
    At present, China spare parts industry is still unable to meet the needs of machine manufacturers, especially in the engine, hydraulic systems and other core parts and components. Therefore, some companies have financial strength to recognize their lack of original supply chain, and actively with international top parts suppliers to cooperate to achieve the overall use of global sourcing to enhance the quality, to seize the international market share. Meanwhile, engineering and hoisting machinery parts exports will be more, showing parts manufacturing system into the international trend.
    4 Engineering and lifting substantial growth in exports to emerging markets.
    In the world economy is not stable, when the majority of developing countries, the situation is not bad, Chinese engineers and crane products are relatively low grade, high cost, have a good market in developing countries is reflected in China to Russia and other CIS member countries, Africa and other developing regions, ASEAN's exports is still rapid growth.
    5 Engineering and lifting import and export agency still promoted.
    Engineering and lifting with a number of base, technological innovation and strong exports of the main force. These companies have their own brand products, with international leadership and vision to fight international marketing talent, after years of development, has gradually emerged in the international market. But the state of export enterprises decentralized management can not be ignored, most enterprises have business instability, inefficient and unable to carry out service and other operating defects. Few export enterprises in the international market to take acts of unfair competition also on the "Made in China" products cause adverse effects.load chain As engineering and hoisting machinery import and export urgent need to establish a sound service system, and in the course of personal safety factors involved, we recommend that an appropriate increase in import and export business of barriers to entry.

"Crane wire rope installation and testing practical norms" national standards GBT5972

State regulations should be considered as a consumable wire rope, when test showed its strength has been reduced to continue to use dangerous, that should be scrapped.
1. Installation
a) The new replacement rope rope should generally be the same type as the original, with the specifications.hoist and trolley If you use different types of wire rope shall ensure that not less than the original replacement wire rope wire rope performance.
b) respond rope through the pulley groove pulley block with radius gauge to accurately measure and record, while using the rope reel inverted dish installation method, that is, from the original tape to be unwound wire rope and wooden wheels on the plate while wearing steel shaft, placed in two dedicated steel frame, while rotating back plate, in order to eliminate the stress generated rope.
c) when installing wire rope,load chain wire rope should be prevented from fighting ring, kink, bend or glue harmful debris.
d) If the wire rope load when certain parts and mechanical friction, you should be able to access the site will be properly protected.
2. Test
a) The user requirements can do regularly observe and record;
b) for lifting the molten or red hot metal, acid, explosives, toxic substances lifting rope, required to check twice a week, usually at least once a month lifting machinery (refer to building site crane) expected rope can be more long-term work of lifting machinery, checked at least once a month;
c) Wire rope inspection site, usually full-length tests, but mainly check the following parts:
* Fixed rope movement and the whole story ends.
* Through the pulley block or bypass pulley rope segment, the mechanical performance of repetitive tasks case, you should pay particular attention to mechanical pulley hanging out around any part of the period.
* Located balance rope pulley rope segment or easy to wear rope segments.
* Rope end portion (crimp rope end buckle rope ends,lift hoist wedge rope end fittings, rope clamp strong side, the pressure pull fixed rope end)
* For use pressed or forged steel rope clamp Si Shengsheng Folder To examine whether there are cracks and use of materials in the presence or absence of the wire rope and rope slip between folders.

Six technical maintenance lift hoist motor

lift hoist motor is an important part, but also the most expensive parts in winch, if damaged, repair or replacement costs will be very expensive. Remind customers to take good care  hoist equipment es, tips are as follows:
1, the use of the environment should be kept dry, the motor surface should be kept clean, air inlet should not be dust, fibers and other obstacles.
2, when the motor thermal protection succession of action, should identify the fault or from a motor overload protection device or the setting value is too low, eliminating the fault can be put into operation.
3, should ensure that the motor is running good lubrication. General motors running 5000 hours or so, which should supplement or replace the grease is found bearing overheating or running metamorphic lubrication, hydraulic in time for grease. Replace grease should remove the old oil, and gasoline wash bearings and bearing cap tank, then ZL-3 lithium grease fills the cavity between the bearing inner and outer rings 1/2 (for 2-pole) and 2/3 (4,6,8 pole pair).
4, when the end of life of the bearing,wire rope winch vibration and noise motor operation will significantly increase, check the bearing radial clearance reached the following values, which should replace the bearings.
5, disassemble the motor, extending from the shaft end or side rotor can be removed. If you do not need to remove the fan, or removed from the non-drive end rotor is more convenient, out of the rotor from the stator, should prevent damage to the stator windings or insulation.
6, the replacement must write down the winding primary winding form, size and number of turns, wire, etc., when the loss of these data, should be obtained from the manufacturer, free to change the original design of the winding, often made of one or several performance motor deteriorated even not be used.

How to maintain electric lift hoist?

lift hoist will directly affect the device's safety, reliability lifting and transportation, so the need to strengthen the maintenance of home for electric winch.
1 home for routine maintenance.Manual hoist Should always adhere to the mechanical, electrical, local cleaning various activities locally sufficient lubrication. Brakes, clutch, bearing, reliable operation of the controller, such as whether the action is malfunctioning.
Always check the status of copper wire rope, change. Connections are secure, for wear broken wire, problems and timely disposal or replacement, after work should be folded rope, with protective cover, broken stick in power, unplug the security.

2, regular maintenance care of themselves. General windlass work should be carried out one after 100-300 hours of maintenance. Re-lubrication, checking each part of the work situation, but according to the specified lubricant or supplemental oil, electric windlass working 600 hours later, two maintenance should be carried out, and its contents for the determination of the insulation resistance, dismantling the motor, speed reducer, brakes and power supply system, cleaning the motor bearings.
In order to determine its contents motor insulation resistance level maintenance. Dismantling the motor, speed reducer, brake and power systems, cleaning the motor bearings, oil change, detailed examination of the quality status of the rope and so on.

Excessive noise when using lift hoists how to do?

Windlass great many causes excessive noise, but the essence is the result of shock and vibration, generally due to the poor quality of the gear meshing, movement is not smooth in motion produces instantaneous acceleration caused. , Here you explain too much noise when using  Hoist equipment  how to do?
Design and manufacture of chassis caused by the presence of noise may: ① chassis with box-shaped structure, not all welds are continuous welding, various chassis weld length, height different positions, there is a big individual differences in chassis rigidity, while others resonate effect, if any one o'clock machine vibration noise is amplified; ② by a steel plate welded into the chassis, do not have the shock absorption silencer function if its natural frequency and the gear mesh frequency is close to the individual machines may cause weak due to vibration caused by the larger gear total shock, cause noise value rises.
Bearing clearance who believe that since the noise is accompanied by drum assembly and transmission parts, then it may be due to the roll bearing large gap caused.

Workaround:
1, we focused on the possibilities were tested, but through three experiments found that the noise level and chassis structure, stiffness, frequency and other factors were weakly correlated noise is strongly related to the size of moving parts, so constructed chassis design, manufacturing quality is not excessive noise causes.
2, we choose the roll parts with the gap, the gap to ensure compliance with the spindle bearing bore drawings,chain block test after assembly. Test using frequency motor speed, observe speed on the noise.
Large number of experimental results show that the speed of the noise impact is the first one, the higher the speed the noise roll larger the value the more intense vibration machine; gap in the second, the spindle and sleeve gap the greater the greater the noise; while the chassis minimal impact on noise. If the machine is already very low noise, the speed level, the spindle gap size changes will not produce excessive noise, which shows that excessive noise nor by the bearing clearance.
