Introduction of Mobile Double Girder Gantry Crane

1. Mobile double girder gantry crane consists of below main parts: the bridge structure, the trolley traveling mechanism, crane traveling mechanism and the electric equipment, 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 etc.
2. The lifting mechanism is electric trolley, it can equip with hook and other tools to lift containers. Some rail, gear, wheel relevant parts with good quality manufactured by our own group, the quality is easily been controlled.
3. Mobile double girder gantry crane has two kind conductive forms: cable and slip line. Slip line are first recommended.
4. All Mobile double girder 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.
Crane Configuration:
Material: Steel plate material Q235 or Q345B ( similar international steel plate FE3 or FE52)
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 quenchingv Main electrical parts: Schneider brand or Siemens brand.

Feature of Mobile Double Girder Gantry Crane

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.
