• Chain Block: Also known as a ''chain hoist'' or ''block and tackle'', the device can move a load by pulling a chain. Unlike lever hoists, operators can operate chain hoists from the ground even when the hoist is positioned up high. A block and tackle product is typically used vertically to lift/lower a heavy load.
• Lever Hoist: It is operated by cranking the lever/handle forwards and backwards with one hand only. With the advantage of being able to lift in vertical and horizontal positions, this device is ideal for pulling, dragging, stretching, tensioning in numerous industrial applications.
• 1. Suspend: Common ways to suspend a hoist is by attaching its top hook to a beam with a beam clamp or to a secure anchor with a shackle. If the load has to be traversed, a trolley will be the right suspension choice.
• 2. Secure: After securing the hoist, position it directly above the load to be lifted and keep the centre of gravity as much as possible. The load has to be attached firmly onto the bottom hook e.g. via lifting sling
• 3. Operate: You can now put it to use for your application by pulling the hand chain by hands. Avoid pulling it too hard or making any sudden movements.
With similar suspension and load attachment methods to chain hoists', this mechanical device has a lever that can be cranked up and down to move an object. By switching the pawl rod lever, you can easily change the operation direction:
• Raise the load: Turn pawl rod lever to the lifting position (⬆) and operate the lever with a pumping action.
• Lower the load: Turn pawl rod lever to the lowering position (⬇) and operate the lever with a pumping action.
• Adjust the chain length: Turn pawl rod lever to the neutral position (central). The chain can now be pulled in both directions.
