Double Girder Gantry Crane Cantilever Rated Lifting Capacity 50T

Double girder gantry crane cantilever is a professional machine for material handling, and it can be designed in different working duty(ISO A3~A7) according to user’s requirements. So the crane is widely applied to material stocks area, cement plant, granite industry, construction industry, engineering industry and so on.

It is composed of double main girder, four supporting legs, two sets sills, hoisting trolley, cab and electrical control system, among which the main girder and supporting leg could be box type or truss type structure, box type is a stronger and compact design, while the truss type has more powerful wind resistance, so if your place is a windy area and the crane works outdoor, the truss is a better choice. As to the control method, it could be ground control, remote control, cabin control or both. If the working temperature is high, air conditioner can be equipped in cabin for the operator.

Double girder gantry cranes with cantilever can be divided into:

1. Double cantilever gantry cranes: The most common type of structure, the structural forces and the effective use of the site area are reasonable.

2. Single cantilever gantry crane: This type of structure is often selected because of site constraints.
