Application
U type double girders gantry crane is widely used in railway, highway, bridge building, power station, ship building for general service, such as loading, unloading, lifting and transferring work in ports, mines, warehouse, docks and outdoor yards of the factory or on railways, also works as container crane matching special hang parts.
Introduction
U type double girders gantry crane is mainly consisting of the skeleton structure, lifting and cross travelling mechanism, long travelling mechanism, cabin and electrical control system. The trolley can move horizontally on a pair of rails on the beam.
The main beam can be design to boxed or trussed type in according to your working environment situation. (Trussed type is normally using in wind-pressure environment)
This crane legs design is like a letter"U", provide enough place for large items.
Notes:
1. The length of cantilevers can be designed as your actual working demand.
2.U type double girders gantry crane control way is always cabin control, it with high working efficient.
And the cabin inside devices list below:
Cabin used for operating, with seats inside. Floor adopts insulation pads and toughened glass for windows; extinguisher and fan are equipped. Other accessory equipment like air-condition, buzzer, interphone and etc can be configured according to our client’s request!
Crane Configuration:

Steel structure: Strong Steel box type, seamless type, more strong and elegant beam.
Crane traveling motor: Soft start type
Wheel:Vacuum casting by our group, Inter medium frequency quenching
Main electrical parts: Schneider brand or Siemens brand.
1. Limit Switch: Safety limit switches for stoppers prevent over traveling in all motions.
2. Anti collision device
When two crane traveling on the same rail, the cranes will install the following devices:
Anti-collision device, Infrared non-contact and inductive type limit device
Sound and light alarm device, Wireless anti-collision device
3. Weight overload protection device
Includes automatic stopping type lifting weight limiter and weight display device.
4. Lifting limit switch and traveling limit switch
5. Emergency stop system
6. Electrical protection
The main insulation switch, emergency stop switch, short circuit, Zero voltage protection, loss of field protection, Current overload protection, over speed protection, zero position protection
Phase sequence protection and adopted crane specially anti- vibration contactor etc.
7. Interlock device
It sets interlock device for the cabin door and the other door from cabin into bridge structure, when the door is opened, the crane cannot work.
