For a long time, human beings have been thinking of making a device for transporting heavy objects to make works such as pyramids, etc. For this purpose, devices that are very similar to modern arm cranes have been invented and used.
A forklift is a machine that performs the operation of lifting and lowering in a vertical plane well. Hoists are used in different types to hoist heavy objects. The forklift can undoubtedly be called the most important component of the crane system, because the forklifts perform the task of lifting and lowering the load. The crane hoists the loads up and down using a drum or a wheel in which the towline or any chain is wound.
The hoists are either fixed at a point that only performs up and down operation or are placed on a horizontal beam (the main beam of the crane) which, in addition to moving up and down, also move left and right. Forklifts used for this purpose must be equipped with trolleys or carriages. In single-axle cranes, hoists are equipped with trolleys that move under one pole, but in double-bridge cranes, hoists are equipped with carriages that move on two main poles (main bridges).
Chain hoists are an optimal choice for loads with a capacity of less than 5 tons. These hoists are made in two types, manual and electric. The relationship between the hook and the body (hoisting system) is the chain. Due to the high occupation of the chain, the construction of these hoists is limited; Of course, in special cases, chain hoists up to 100 tons have been built. Another limitation of these hoists is the length of the chain (hoist height). In all cranes, the load is lifted by a device called a hoist or winch.
In these hoists, the connection between the hook and the body (hoisting system) is a wire rope that is wrapped around the drum and the rotation of the drum causes the hook to be transferred and makes it possible to carry or load.
From electric chain hoists, manual, explosion-proof, hoisting, normal and explosion-proof tow rope hoists with custom design in different types and tonnages. And offer in accordance with your industry and production plan.
