Lever hoist lever hoist safety requirements is a lightweight and simple manual traction machine. It has a compact structure, small size, light weight, easy to carry, stable performance characteristics. It works by two pairs of smooth self-locking clamp, the same as two alternating steel claw clip rope, for linear reciprocating motion to achieve the towing operation. It served as the traction in a variety of projects, winch. Lifting and other operations. In addition can be used in horizontal and vertical direction, but it can also be operated at the slopes, rugged, narrow roadway, tortuous turns working conditions, but also can be used anywhere and no power supply environment. Lever hoist at the construction site often used for handling, installation of small equipment, small components and pipes and other tools. Safety requirements for use: 1, when used lever hoist, from the weight must not exceed the permitted load, according to the mark from the weight to use. 2, can not any longer when using the handle lever hoist, lever hoist from the weight due to a limited, two-handed pull force also has a certain size, longer handle will cause the use of lever hoist overload, resulting in damage to parts. 3, the rope should always check for wear and kinks, broken wires, broken stocks, which do not meet the safe use must be replaced. 4, due to the lever hoist working principle is to use alternate clamping rope clamp, it requires the use of a steel core wire rope core rather than using hemp rope, hemp core due to soft and elastic rope, after clamping jaws have easy loose phenomenon, is unsafe. 5, the front lever hoist to make full use of inspection and testing, maintenance and after use. Chain lever hoist, also known as inverted chain lever hoist is a manual lifting tool for heavy duty work level. Chain lever hoist operation is very simple mini lever hoist, which is driven by human rope or chain through the handle, to drive extract device movement lifting gear. Its compact, easy to wire rope pulling hoist, easy to operate, suitable for remote areas and field of lifting, pulling cited work, and to enhance and entrainment unlimited distance, by the choice of rope or chain length may be carrying. Chain lever hoist is suitable for a variety of occasions in factories, mines, construction sites, docks, transportation, etc., is the equipment installation, cargo lifting, stationary objects, ideal tool for banding and traction, especially traction at any angle and in small venues, the case of open operation and no power, but also demonstrate its superiority. Chain lever hoist a new, efficient, safe, durable with lifting, pulling, tensioning three functions, the whole structure design, high safety factor, long life, especially suitable for field conditions no power source.
