Double Girder gantry crane Machine
This crane use one or two trolley as its lifting machine, comprising the crane and trolley traveling mechanism, lifting mechanism, cabin, computer room, electric room, and others.

Double Girder gantry crane Power supply
This type crane adopts the cable and drum or the slide wire as its conductive devices.

Double Girder gantry crane Cabin
All mechanism of this crane is operated in cabin. The cabin travelled along with the crane to avoid the crash with the cargo. In the cabin, the operator not only can feel its wide and comfortable space, can also have a good vision to control, surveil and maintain.

Double Girder gantry crane Electric equipment
All electric equipment can works normally within the voltage fluctuation range -15% or +10%. We also design the protection devices, for instance, the emergency stop system, current overload protection system, voltage lower protection function, and etc. The main electrical components (frequency inverter, PLC) adopt the Siemens, Schneider, Chint or other international famous brand.

Double Girder gantry crane Safety protection devices
Weight overloads protector, extreme lifting position limiter, extreme travelling position limiter, the cleaning board, the buffer and the cover protection.

Double Girder gantry crane Painting and protection
All gantry crane components are handled with shot peening, then painting. Before delivery, we will do the rust-proof protection on all open parts. The painting color and shape is according the customers demands.
