Introduction and principle of hoist

The working principle of the Manual block is the use of wire rope clamp clamped alternately, so requires the use of steel core wire rope core and not with hemp rope, hemp core rope due to soft and elastic, the clamp after loosening the clamping phenomenon that is unsafe. When using the lever hoist, lifting allowed to exceed the allowable load, according to the marks from the weight used. Always check the rope for wear and kinks, broken wires, broken stocks, which do not meet the safe use must be replaced.

With the provisions of models, specifications of wire rope to hoist securely fixed. Wire rope hoist, synthetic material is generally metal, so it must be done in full respect of maintenance, in order to not affect normal use of equipment. Usually comes with squirrel cage conical rotor brake motors, hoist widely used in shipbuilding, electric power, transportation, construction, mining, telecommunications and other sectors of the equipment installation, lifting items, mechanical retraction. More kinds of electric hoist wire rope electric hoist mainly Wire rope hoist , chain electric hoist, mini electric hoist and electric hoist several models. It can be enhanced traction, down, calibration and other operations. If you configure a special device, not only can be used for non-linear traction operation, and can easily select the appropriate operating position, or with a smaller tonnage machines exponentially expand its load capacity, the load can be used for larger tonnage of several machines in parallel operations.

Chain lever hoist is also known as inverted chain lever hoist is a kind of manual lifting tool for heavy duty level. Chain lever hoist is driven by a human through the handle rope or chain to drive extract lifting device movement. Its compact, easy to carry, easy to operate, suitable for remote and wild lifting, pulling cited work, but lifting and pulled cited distance unrestricted by the choice of rope or chain length. Advanced structure, the use of safe, reliable and durable. Gears and shafts rotating at both bearings or bushings, products can meet 150% of rated load weight machine, high efficiency, simple operation, comfortable. Machine, high efficiency, simple operation, comfortable. Manual hoist
