The wire rope electric hoist inspection and maintenance

    Wire rope hoist  used equipment links between the subject and the hook, play an irreplaceable role in any parts of its service life when used with our daily and is closely related to the maintenance, introduction to the use of wire rope inspection and maintenance.
      Before rope lubrication should rope appearance backlog cleaned of dirt and rust, grease, heated to 60 ° C or so, the grease can fully penetrate into the interior rope.
Wire rope electric hoist work inevitably tension, compression, friction, torsion loads. At the same time, followed by rope through the pulley ethephon, when not affected by repeated bending and squeezing effects arise from broken wire fatigue phenomenon, coupled with other factors such as wear and corrosion, increased development of Wire Ropes, so we deal with every week conduct a visual inspection of wire rope, a small number of broken wires should be properly disposed of, to prevent broken wires so that other broken wires, wire rope for individual segments, should be promptly amputated
      Fixed  Rope hoist  for not reversed, because the special structure surround entanglement must not disrupt or interfere when the original fixed pitch between the strands to prevent slippage or outer core rope slack strands forming the cage shape. In the pulley, when the rope around the pulley, the rope being repeated reverse bending, the bending stress in the direction also changes, this alternating stress, certainly reduce the life of wire rope, therefore, the use of pulleys, best to use the rope bent in the same direction as the pulley.

Electric wire rope hoist is a two-cylinder

    Wire rope hoist  is a hoist two is an essential cylinder device, the two devices is the overload limiter, breaking firearms, a talking drum rope drum.
      Electric wire rope hoist overload limiter main role is played in working condition when the  Rope hoist  judgment device, make the appropriate sound and light indication, such as normal lifting condition, fully loaded lifting state overload lifting the state of automation monitoring equipment, automatic alarm when overload will stop lifting weights.
      Electric wire rope hoist is mainly used firearms off the voltage to 380V, DC to 220V, 50Hz AC power lines to use. This is mainly used off the fire stopper 0.5 tons to 10 tons CD1 and MD1 model electric hoist electric hoist up, down limit protection purposes. Breaking quick direct upgrade hoist the main circuit.
      wire rope hoist  rope winding drum is used, generally CD1 electric hoist drum has a cable device, so that the roll of wire rope and then chaos will not be involved, and this is rising, falling, lifting and tightening up rope A major component of wire rope.

Replacing the wire rope hoist

       Wire rope hoist  rope  is used to connect the main part of the hook, is to ensure the normal operation of hoist one essential accessory, but after prolonged use of wire rope electric hoist parts will wear, or there will be a slight bite rope rope phenomenon, Even more serious is biting rope wire rope breaking phenomenon occurred, processing methods can only replace the wire rope. For you to explain to replace wire rope electric hoist ways to ensure your efficiency.
      First make  rope hoist  hook down the bottom, put the reel guidewire removed Used hex wrench, remove the rope on the drum three pressure plates and a rope has been falling. After the hook out of the other end of the rope removed, using a feeler iron fixed, remove the tie clip with a wrench after the iron with a hammer and a sharp upward break out of the iron game, this time electric wire rope hoist completely removed, the method steps above to install the new rope.
