Double Girder gantry crane


Overview

Gantry Crane is new designed crane according to FEM/DIN, with small limit size, low power consumption; overall processing, high precision, low noise; modular design, transportation and installation is simple; frequency control, smooth operation and high efficiency. Cranes are mainly made up by beams, legs, trolleys, electrical parts and control rooms and other components.


The heavy load of double Girder Gantry Cranes is up to 700T and the spans can be over 50 meters. For fabrication and freight-transfer applications, it can move loads rapidly and smoothly.


Features of Double Girder Gantry Crane

-Designed for indoor or outdoor use,heavy duty works.
-Equipped with high quality gearbox; SEW/ABB can be as optional according to clients' special requirement.

-Safety limit switches for stoppers will be provided to prevent over traveling in all motions 
-Main electrical devices are of Siemens or Schneider brand
-Power supply of Crane is through Cable drum/Energetic Chain
-Controlled via push button pendant/Radio remote/Cabin, separately or any combination.

-Tailored based on client's detailed requirement.


The Gantry Crane can be designed into different types to meet various requirements:

-Single girder gantry crane for small lifting capacity

-L type single girder crane utilizing the space with simple structure and light dead weight.

-Double girder gantry crane for heavy lifting capacity with more rigid structure

-Semi Gantry crane can minimum the cost and take full advantage of the existing building construction.

-Truss Gantry Crane can be applied where the speed of wind is high, and low cost requirements

-Gantry Crane with cantilevers to meet the requirement of loading and unloading in side area.
