Lever blocks are transportable mechanisms that are used to lift, pull or lower a consignment manually. A lever block is also an ideal machine for tensioning. These mechanisms are capable of lifting loads effectively in all positions. These machines are available in two models or designs, one with an attached chain for lifting the loads. The other model comes with a wire cable intended for lashing and dragging the loads.
As the name suggests, a lever block comes fitted with a lever or handle, housing an interior gear arrangement and a ratchet, together with: a long load chain or a long wire rope. While the chain will move over the inside gear, the wire rope will run through a pulley.
To make the level block work, you have to crank the handle up and down. This will operate the pawl system and the ratchet of the device. As a result, the pawl system will shift the load to a preset distance for each crank. Whether the lever block is a chain or a wire rope model, you can change the direction of the inside gear easily. Every device comes with a hook, which is used to hold the load safely and firmly.
The load cable or chain on the machine is available in a standard length that ranges from 1.5 meters to 3.0 meters. If you need a more lengthy cable or chain, you can order it separately according to the nature of your tasks.
Every specialized lifting lever block will be designed to a precise working weight limit, such as 2 tons. This means that the device will be capable of bearing the maximum weight of 2 tons, including the weight of the load and the weight of any attached rigging tool. The working weight limit of the mechanism will be clearly shown on its side, together with its serial number and the name of its manufacturer. These machines are generally available with different working weight limits that range from 250 kilograms to as much as 10 tonnes.
If you want to lash or pull the load using a lever block, you can do it with less effort. These machines are mostly used in the transportation industry for pulling or tensioning a heavy consignment. These blocks are also used in other projects, such as pipe laying, power line work, confined space, forestry, and heavy equipment work. The pulling capability of the wire cable model of the device will be clearly shown on its housing. These lever hoists are available in different pulling capacities that range from 2 tons to 9 tons.
