Professional Double Beam

Gantry Railway Crane Manufacturers

Brief introduction:

Professional double beam gantry railway crane is widely applied to do loading and unloading work in outdoor. Such as material stocks area, cement plant, granite industry, construction industry, and enginer industry and so on.

A double girder hook gantry crane is composed of beam, support legs, crane traveling mechanism, trolley, electric equipment and so on.

It has features of beautiful and durable appearance, perfect performance, low cost, easy maintenance, high adaptability and so on. It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork.

They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, and where additional supporting steelwork would result in a loss of floor area. It can be constructed with a cantilever to allow handling outside the rail centers. The frame adopts box-type

welding mechanism, the A model double girder hook gantry crane is welding structure in order to increases the work space. Crane traveling mechanism adopts separate drive.
