Product Description

The rubber-tired gantry crane can realize a variety of modes such as straight travel, diagonal travel, horizontal travel, in-situ rotation, Ackerman steering, etc.
It has mobility, flexibility, adaptability, high work efficiency, small size occupation area and do not need to lay the rail which are particularly suitable for beam factories with horizontal layout. The rubber Tired gantry crane can work independently or collaborative work by two units.
The crane mainly consists of main beam, support leg, hoisting mechanism, tire walking and braking system, steering mechanism, power system, electrical system, hydraulic system, hydraulic transmission system, cab, control system, safety device, etc.

1. The electrical equipment is accommodated in robust steel plate control cubicles.
2. All movement can be switched off by actuating the emergency-off switch at the control station via a main contactor.
3. The entire equipment is easy to install and dismantle due to the use of threaded bolts and top-hat rails. Cable inlet from the cable gland.
4. Power supply cable and control cable along the girder
5. A protective earth conductor is fitted as standard, a crane switch is provided.
6. Travel end switches, long and cross travel limited by means of preliminary and final limited switches and overload protection.
 

Environmental Conditions:
1,The power source is three-phase alternating current,rated frequency is 50HZ,rated voltage is 380V.
2,The working environment temperature ranges from -20ºC to +45ºC and the relative humidity is no lower than 95%(with dew).
3,In-service, the wind speed should be no higher than 20m/s; out-of-service, the wind speed should be no higher than 44m/s.
4,The working duty is A6-A7.
5,The gradient of crane traveling floor should be less than 1% and part of that should be no more than 3%.
6,The crane which has the special requirement for working conditions, can be manufactured following the contracts.
