Overhead Crane Specifications

Overhead crane is a lifting equipment that spans the width of the workshop, warehouse or material yard for material lifting. The bridge runs longitudinally along the rails laid on the elevated runway beams, which can make full use of the space under the bridge without being hindered by ground equipment. As one of the most widely used heavy lifting equipment, overhead cranes come in a wide varieties to suit different facility conditions and lifting requirements.

Overhead Crane Parameters

The main technical parameters of the overhead crane are lifting capacity, span, lifting height, running speed, lifting speed, working duty, etc.

Lifting capacity

Lifting capacity, also known as rated lifting capacity, refers to the maximum allowable lifting load of the crane, in tons (t).

The lifting capacity of the overhead crane can be 5t, 10t (single hook), 15t/3t, 20t/5t, 30t/5t, 50t/10t, 75t/20t, 100t/20t, 125t/20t, 150t/30t, 200t/30t, 250t/30t (double hook) and many others. The numerator in the number is the primary hook weight, and the denominator is the secondary hook weight. For example, 15t/3t crane means that the rated lifting capacity of the main hook is 15t, and the auxiliary hook is 3t.

Bridge cranes can be divided into three grades according to the lifting weight: 5~10t small overhead crane, 10~50t medium overhead crane, and more than 50t heavy duty overhead crane.

Span

The span of a bridge crane refers to the distance between the center lines of the wheels at both ends of the main beam of the crane, that is, the distance between the center lines of the cart tracks, in meters (m).

Overhead crane spans can be 10.5m, 13.5m, 16.5m, 19.5m, 22.5m, 25.5m, 28.5m, 31.5m and many others.

Lifting height

Lifting height refers to the distance between the upper limit position and the lower limit position of a crane’s hook or grabbing device, such as grab, electromagnetic chuck, etc.

The lifting height of an overhead crane can be 12m, 16m, 12m/14m, 12m/18m, 16m/18m, 19m/21m, 20m/22m, 21m/23m, 22m/26m, 24m/26m and so on. The numerator in the number is the primary hook lifting height, and the denominator is the auxiliary hook lifting height.

Running speed

Running speed refers to the speed of running mechanisms of the crane and the trolley.

Lifting speed

Lifting speed refers to the speed at which the motor of the lifting mechanism raises the heavy object at the rated speed, which is determined according to the properties of heavy objects, weight, and lifting requirements.

Work duty

Work duty of the crane is determined according to its load rate and busyness, and can be divided into four types: light, medium, heavy and extra heavy.

Light duty: used in workplaces for light service. For example, overhead cranes used in hydropower stations and power plants for installation and maintenance purposes.
Medium: often works under different loads, the speed is medium, and the work is not too heavy, such as the cranes used in general machining workshops and assembly workshops.
Heavy duty: often works under heavy load, such as cranes used in metallurgy and foundry workshops.
Extra heavy: often works at rated load, such as bridge cranes for metallurgy.
