Ratchet Lever Hoists-HSHD Series | Lever Blocks | China Wirstrong® Manufacturing
A lever hoist is a manual device used to lift, lower, or pull a load and to apply or release tension. It utilizes a ratchet and pawl mechanical configuration to incrementally raise or lower a load or to apply or release tension.
Lever hoists and pullers have the advantage of being easy to transport, require minimum set-up, and are a practical option in confined spaces. They are suitable for different applications ranging from heavy-duty construction work to day-to-day maintenance and repair jobs.
Feathures Of Lever Blocks-Ratchet Lever Hoists-HSHD Series:
-Tough framing.
-Machined chain sprockets of the load sheave can ensure the sm-ooth operation of the chain.
-The lever with ribs along edge provide high strength and high ability to fight against deformation.
-Reliable brake mechanism, when the load slip quickly by accident, the brake works immediately to stop the slipping.
-Idling mechanism to allow fast adjustment of load chain. Set the switching lever to the center(N) position, turn the hand wheel or operate the lever anticlockwise, then, pull the chain lightly and smoothly by hand to hand to adjust the chain up and down.
-Complies with EC Council Directive 2006/42/EC Machinery, ASME B30.16, AS 1418.2.
