Rail Mounted Gantry (RMG) cranes

Rail mounted gantry cranes (RMG cranes) are rail mounted bridge cranes which are mainly used for stacking containers. They are available in a variety of different widths and heights.

There is space between the supports for approx. 6-20 containers lined up lengthways. It is possible for 4-6 containers to be stacked on top of each other.

The drive power of the hoisting motor depends primarily on the hoisting speed and is between 250 and 355 kilowatts. The trolley travelling winch is moved by means of 4 drive motors, each with a capacity of 25 kilowatts and, in order to drive the crane, the steel wheels are often equipped with either 8 or 12 drive motors each with 30 kilowatt capacity.

Our drive motors are produced individually for use in RMG cranes and, in comparison with serial motors, are extremely efficient. This means a significant reduction in energy costs. A system equipped with Wölfer motors pays for itself within a short time. We supply these RMG drive motors directly to the constructors or outfitters and also offer spare parts deliveries and services at service@woelfer-motoren.com or 0049 541 99022 99.
