How does wire rope rotate on the drum?

Wire rope is an important part of lifting hoist, so it is vital to make sure the wire rope rotate on the drum in order, the item can perform well.

The way of rotation has two ways, monolayer and multilayer. For monolayer, it refers to the drum with rope groove, namely rope-guide. It benefits to arrange wire rope on the drum on order, avoid wire rope in mess. To prolong the service life of wire rope and rope-guide, we must strictly obey the rules of maintenance manual, not drag or lift in slide way. For multilayer, its important point is that the wire rope of first layer should rotate with pulling force. Avoid inner wire ropes loose, so that they are squeezed or pressed by the outer wire rope to groove and damaged.

Generally the tighter the wire rope pulls, the better it rotates. The advantage of multilayer is that it can save the hoist volume itself, reduce producing cost. It is more widely used for lifting height more than 30 meters.

Electric lifting hoist system

A hoist is used to lift or lower very heavy loads. In most applications a hoist is suspended overhead by a lug, a trolley or a hook. It can be permanently mounted in a fixed position using a lug or a hook, or it can be affixed to a trolley which travels on an overhead beam or rail. A trolley is used when the hoist is applied to move a load from one place to another.

Electric lifting hoists and trolleys are powered by electricity or air and come in different configurations and shapes to suit the specific requirements of the loads that need to be moved. Loads are suspended and moved up or down by a coil or link chain, a roller chain, a wire rope, or other materials used in specialized applications, such as high tensile fabric.

Overhead electric lifting hoist systems

Electric overhead hoists are used for applications that require fast and frequent lifting such as factory production lines. For repetitive lifts over long distances an electric lifting hoist and a motorized trolley are essential. Electric hoists and motorized trolleys come in a wide range of speeds and capacities.

An electric lifting hoist is similar in design to a mechanical hoist except that physical force, (applied to a lever or hand chain by an operator)is replaced by a controlled electric motor. Controls are used to start and stop the motor and to control its direction. These hoist and trolley motions are normally controlled from a push-button pendant station.

Electric lifting hoist systems are available in lug, hook or trolley suspensions that can be hand-geared, push type or motorized. The lifting medium can be roller or coil type chain or a wire rope. Wire rope hoists are used to attain faster speeds, higher capacities and smoother lifts.

The most popular chain hoists are coil or roller hoists for 3-ton or smaller sizes because they are generally lighter, smaller and less expensive to manufacture. Chain lifting hoists provide a true vertical lift, which means that the load will not vary from the hoist center line during lifting or lowering. However, wire rope units can be specially constructed to provide true vertical lift. Electric chain hoists come with either a four wheel motorized trolley or a six-wheel motorized trolley.

Parameters for overhead electric lifting hoists

When specifying overhead electric lifting hoists there are important parameters to consider, such as:

Lifting height

Frequency of lifts

Speed of lifts

Weight load

Power supply

Cost

Duty cycle

When choosing an electric hoist lifting system for a particular application, one of the most important things to consider is the duty cycle. A duty cycle can be defined as a specific number of operations at specified intervals. For an electric hoist application this means the amount of work the hoist is required to perform in a stated period of time. When determining the duty cycle capability of a specific electric hoist, the following play an important role:

The lifting distance

The load weight

Frequency of operation

The duty cycle requirements have been classified by the Hoist Manufacturers Institute according to hoist class: H1, H2, H3, H4, H5. This information is used by most hoist manufacturers in a catalogue for customer use. In general, today all industrial grade electric lifting hoists on the U.S. market meet a minimum requirement of an H3 duty cycle.
