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.

Rail mounted container gantry cranes (RMG) design manufacture inspection adopts DIN FEM IEC international standards.

The RMG has the advantage of being driven by electrical power, clean and no pollution, bigger lifting capacity, stable performance, high efficiency, easy maintenance.

1. Both side of all the steel plate of crane are pretreatment by pretreatment production line, Sand blasting-- Primer spray--Primer drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.

2. Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.

3. The welding of main beam adapt high efficiency and intelligent welding robot, Henan Mine Crane CO., LTD are No.1 enterprise who adapt this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.                        

4. The welding of main beam adapt radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position

5. The welding of end beam adapt double gun gantry submerged arc welding, highly welding quality ensure the stable quality of the crane effectively.

6. Adapt the steel plate rolling drum and wireless steel tube, Henan Mine Crane CO., LTD has a set of steel plate rolling drum producing and processing line which is industry-leading level. From pre-bending by 1250t press machine, to Edge rolling by three-roller plate roll, at last the longitudinal joint and circumferential joint of drum are welded by automatic welding center and drum processed by heavy duty CNC horizontal machine tool.
