Hand lever block is a high-efficiency and versatile manual hoisting machine. It is widely used in the design and installation of shipbuilding, electric power, transportation, construction, mining and other departments, lifting of items, etc., especially in small workplaces, in the field, in the sky. And the traction of various angles has unique advantages.
When operating, the hook of the manual hand hoist and the fixture are reliably fixed by the wire rope, and the chain hook is reliably hung with the weight to be hoisted. Move the knob to the "up" of the position card, and then reciprocately move the handle. As the handle moves back and forth, the weight will rise smoothly.
Move the knob to the "down" position on the sign, then reciprocately move the handle, and the weight will drop smoothly as the handle moves. If you need to adjust the position of the manual hand hoist hook, when the idling is turned to the "0" on the indication, then turn the handwheel to adjust the upper and lower position of the chain hook to disengage the ratchet. This makes it possible to adjust the position of the chain hook easily and quickly by pulling the chain.
