FAQs

What Is an Overhead Crane Used for?

To move extremely heavy or bulky loads through the overhead space in a facility, instead of through aisles or on the floor, an overhead crane is a machine that lifts, lowers and moves a load from one work cell to another as required.

What Are the Main Parts of an Overhead Crane?
The principal parts of overhead traveling cranes are: main beam, end beam, lifting mechanism, travelling mechanism, electrical system and so on.
How Are Overhead Cranes Used?

Overhead Cranes are used in various places to support processing and handling throughout a facility:

➢ Assembly: Moving products through production process

➢ Transportation: Loading or moving finished products onto open trailers or railcars

➢ Staging: Holding work-in-process for additional production process

➢ Storage: Transporting heavy materials to and from storage areas as required

➢ Warehousing: Moving large, heavy products or items to and from docks

What Are the Movement Forms of Overhead Crane?

There are mainly three types of movement form of the overhead cranes as follows:

➢ The overhead crane is driven by the crane motor and moves forward and backward longitudinally along the tracks on both sides of the workshop;

➢ The trolley and lifting mechanism on the main girder of the crane are driven by the trolley motor to move laterally left and right along the main girder track of the bridge;

➢ Lifting motor (main hook and auxiliary hook) drives heavy objects to do vertical lifting movement.

What Are the Main Technical Parameters of Overhead Crane?
The main technical parameters of the overhead crane include lifting capacity, span, lifting height, running speed, lifting speed, working type and power on duration of the motor, etc
➢ Lifting Capacity
Lifting capacity, also known as rated lifting capacity, refers to the actual maximum allowable lifting capacity of the crane, in tons (T).According to the lifting capacity, the bridge crane can be divided into three grades: small crane of 5-10t, medium crane of 10-50t and heavy crane of more than 50t.

➢ Lifting Height
The distance between the upper limit position and the lower limit position of the crane’s spreader or grabbing device (such as grab and electromagnetic suction cup) is called the lifting height of the crane, in meters (m).

➢ Span
The span of the bridge crane refers to the distance between the wheel centerlines at both ends of the main beam of the crane, that is, the distance between the crane track centerlines, in meters (m).

➢ Working Type
The working type of crane is determined by its load rate and busy degree, which can be divided into four grades: Light grade, medium grade, heavy grade and extra heavy grade.
