Several distinguish from wire rope winch the weight

A professional chain hoists, lever hoists, cranes and other lifting equipment line tackle manufacturers, the following are details of the weight of the news brief manual hoist.

     Whether we buy or use a manual hoist the need to use from the weight, in general, from the weight refers liftech 1 ton chain hoist to the quality of heavy lifting, the symbol G. It can be divided into nominal weight, the total starting weight, effective from the weight of several.

     Nominal weight refers to the hoist during normal operation to allow lifting weights or materials, togetherliftech winch snatch block with the sum divided spreader attachment or quality; overall effect is the hoist can lift the weight of heavy objects or materials, together with spreader and can be divided into the quality of long-term fixed sum on a hoist or sling was the case with (including the hook, pulley blocks, lifting wire rope and other hanging objects) of; effective from the weight refers to the net mass hoist can lift heavy objects or materials.

     Several distinguish from the weight, in terms of the purchase or use is more convenient.

in the case of possible energy savings using it to cheap wire rope hoistequipment

 With recent changes in national policy and foreign policy , China's increasing emphasis on marine minerals also , incidentally, the cause of the development of the ship , the development of ocean exploration tools, mining tools , lifting equipment, and so also the government 's attention to the project .
Chain hoist is an easy to carry, liftech ratchet lever block  to operate , and does not require electricity supply lifting equipment capable of prospecting mining process in the ocean , in the case of possible energy savings using it to lifting handling equipment . Therefore, in the case of national policy support , as chain hoists manufacturers have to do is line with the national development strategy, a clear direction , development and production of equipment best suits chain hoists for use in the ocean . Developing countries to develop strategies and programs have three levels liftech mechanical lifting devices of clear direction and focus of the development , namely to develop offshore oil and gas development and equipment to accelerate marine renewable energy , marine chemistry resource development equipment , and actively cultivate wave energy , gas hydrates , undersea metallic minerals , development and utilization of marine biological resources and equipment . Specifically , the recent deep-sea equipment and technology in order to focus on long-term in order to break through the subsea production system to the target .
    Efforts to develop marine equipment , speed up the detection and exploitation of marine mineral is our country's current and future objectives for some time, Shanghai Yuan as a new hoist manufacturer, not only from the quality , but also from product performance and diversity efforts to improve the above , in order to be able to better adapt to the marine operations and subsea operations , improve the industrial system, capable of lifting equipment to ensure a healthy , stable and sustainable development.
