lever hoist is a lightweight and easy manual traction machine. it has a compact structure, small volume, weight light, portable, and stable performance. it works by two pairs of smooth self-locking clamp, the same as the two alternate clip wire rope steel fixing shaft for reciprocating motion, so as to achieve traction operation. it served in various engineering traction, hoist. lifting and other operations. in addition to the horizontal and vertical directions in users, it is also in the slopes, rugged, narrow alleyways, winding turn operate under the conditions of work, but also in any local and non-powered environment. lever block at the construction site often used for loading, unloading, installation of small equipment, pipelines and other small parts and tools.
use requirements:
use lever hoist, the load from the weight must not exceed permitted to use according to the weight from the tag.
should always check whether the wire rope wear and kinks, broken wires, broken stocks, which do not meet the safe use must be replaced.
as the lever hoist works is the use of alternative clamp clamp rope, so require the use of steel core wire rope core and not with hemp rope, hemp rope due to soft and elastic, after clamping the clamp easy to loose phenomenon, is unsafe.
extended use can not handle arbitrary, because the starting weight of lever block is limited, two-handed pull force to a certain extent the size of the longer handle the overload will cause the use lever block, causing parts damage.
lever hoist before using a comprehensive inspection and testing, to maintenance after use.
