Different Types Of Hoists For Different Applications

Hoists are machines that exert a force on a fixed object using a drum or other lifting material. Hoists are commonly used in industries such as construction, power lifting and shipping. Hoists can be both civil and military in purpose built units. There are several types of hoists available depending on the type of job that they are needed for.

Description: A hoist is simply a machine used for lowering or raising a weight by means of a lifting drum or other lifting material around which the chain or rope wraps. In a common design they are controlled by an electric motor. In some cases wire rope, aluminum tubing or fabric cables are used instead of iron rope. Electric hoists can be mechanically, electronically or pneumatically driven.

Most common type hoists winches. A winch is one of the most important pieces of equipment for lifting and lowering heavy loads. There are many types and there are different ways to use them. In the past winches were noisy and powerful machines used mainly for lifting and moving heavy materials but modern designs have reduced their size and power in order to make them quieter, and to make them more energy efficient. Today a winch can also perform other functions such as to raise or lower work platforms and to lift objects on or off work platforms.

Winches can be either counter-weighted or un-counter-weighted. In the former they are designed to stabilize a heavy load in an upright position thereby reducing the strain placed on the suspension system. The un-counter-weighted types are more fuel efficient and require no special handling. Hoists of all kinds can be either internal or external in design. Internal types are generally more costly than external models and have greater longevity and durability, however there are those that are available with internal rotating components that are removable allowing you to replace parts of the hoist anytime you want.

Overhead wire rope hoists use a single wire rope to lift and lower items. It is important to ensure that the installation is correct because if it is not, the chances of the winch breaking are high. Lifting units and winches use different types of materials which determine their longevity and their cost. The most durable and expensive varieties are made from stainless steel wire, while the least expensive ones are made from aluminum or brass. Please see here for better understanding.

There are basically three types of hoists useable by the customer: Chain-driven, drum-driven, and screw-driven. A chain-driven hoist works with two sets of metallic rods attached at the end of the mast sections. Drum-driven hoists use a drum fixed between the two mast sections and are powered through a motor.
