Comparison of Single girder overhead crane and Double girder overhead crane

Single girder overhead crane, double girder overhead crane, which one do you select? What is the similarities, differences, features of each type of overhead cranes? Check the comparisons of single girder overhead crane and double girder overhead crane on working conditions, operation features, production cost, and mechanical properties, etc.

Overhead crane brief

An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge.

Generally, the overhead crane can be divided into two types according to structure: Single girder overhead crane and double girder overhead crane. So how to choose it? This is a question that makes our customer confused.

Some details below can help you to choose the suitable overhead crane for your workshop, if you want to know more, please come to our website and there our engineer can design the unique drawing for your actual workshop.

■ Working condition

Single girder overhead crane is generally used in the small place with short span, light weight, the working duration is not too long.

Double girder overhead crane is applicable to the big workshop shop and the working class will be high which can adapt the heavy capacity and big span. In contrast to the single girder type, the double girder application is more widely.

■ Construction features

Single girder type overhead crane has light dead weight, simple construction features which is easy installation, disassembly and operation.

double girder type overhead crane is heavy and the construction features are complicated so its installation is a little harder than the single girder type.

■ Manufacturing cost

For the manufacturing cost, the main influence factors are lifting capacity and span of the crane. Single girder type, the span and capacity are smaller than double girder type so its materials, technology, labor and production time are less than the double girder type. Therefore, single girder manufacturing cost is lower than double girder type.

■ Operation objects

General operation of the single girder type is pendent control and remote control, but for the double girder type especially the crane with special slings such as grab, magnet and so on which needs the professional operator to control it.

■ Mechanical property

Lifting capacity, lifting speed and stability of the single girder overhead crane are not equal to the double girder overhead crane, so it is better to use for a short period and the light weight products. Double girder type crane can have big capacity, high speed and better performance and longer service life.
