High efficiency rail mounted gantry crane (RMG) used in container yard/railway container terminal
Description of production:
Rail mounted container gantry cranes (RMG) is a specialized container handling machine that is applicable in container yard, railway container terminal, to handle international standard containers.
Rail mounted container gantry cranes (RMG) can travel on rail by means of the yard power, usually powered by cable and cable drum, to lift and stack containers in the yard area with the equipment of the 20' or 40' or 45' telescopic spreader (or twin-lift spreader if needed).
The RMG consists of steel gantry frame, lifting mechanism, trolley traversing mechanism, crane traveling mechanism,container spreader (for 20' / 40' and 45' container) and anti-sway mechanism, electrical control mechanism. The control mode usually is cabin control.
Trolley can be rotating type or spreader to be rotating type, whole trolley can pass through the legs,make bigger working range,working method is more flexible.
Rail mounted container gantry cranes (RMG) has perfect safe device and overload protective device, i.e, anemograph, lighting rod, anchor,rail clamp and wind cable, maximum to guarantee the operator and equipment safe, electrical system adopts PLC to easy control all mechanisms,famous brand parts are choosen to make sure whole crane quality.
The RMG has the advantage of being driven by electrical power, clean and no pollution, bigger lifting capacity, stable performance, high efficiency, easy maintenance.

Advantages:
Intelligent ,Efficient
1.New moment anti roll system:
hrough the reasonable arrangement of guide wheels in horizontal and vertical directions, the movement of four hoisting wire ropes in the space can effectively prevent the swing and torsion of the spreader and greatly improve the working efficiency of the lifting box.
2. Container automatic track and automatic lifting system:
Through the storage, utilization and database management of the location information of each mechanism of the equipment and the container information of the storage yard, the automatic track operation and optimal track control of the mechanism are realized, and the working efficiency of the equipment is improved on the premise of ensuring safety.
Energy-Saving:
1.Energy feedback technology:
With the advanced active inverter technology, the kinetic energy and potential energy stored in the machine can be converted into electrical energy, which can be efficiently fed back to the power grid. At the same time, the pollution of high-order harmonic to the power grid is restrained, and the power factor of the whole machine is improved.
2. Intelligent low voltage capacitance compensation:
Fully automatic dynamic harmonic elimination reactive power compensation device is configured to effectively improve the power factor of the equipment, which can reach more than 0.9, improve the quality of power consumption, reduce line loss, and achieve the purpose of energy conservation and consumption reduction.
Characteristic:
1.Lifting appliance flexible box holding technology:
Adopt advanced software intelligent deceleration technology, cooperate with hardware detection and protection equipment, dynamically adjust the deceleration time and position in the case, reduce the impact on the equipment and the wheel pressure of the whole machine, and improve the service life and stability of the equipment.
2.Windbreak anchoring system:
It is equipped with two sets of independent anchoring devices to resist horizontal force, four sets of windproof cables to resist overturning moment, and four sets of windproof crawlers or wheel clamps to ensure the stability of the whole machine. It can be equipped with electric iron wedge, wheel clamping device, rail clamping device, top rail device and other wind proof devices, which is convenient and reliable for operation.
3.Intelligent rectification technology of gantry:
Through real-time detection of the frame deflection relative to the track, the deflection is used as the control signal to control the frequency converter to adjust the speed of the driving motor in real time, manually or automatically correct the frame deflection, so as to avoid the gantry gnawing the track, ensure the safe operation of the equipment, slow down the wear of the wheel and track, and improve the service life of the equipment.
