Rail-mounted gantry cranes (RMG) are specialized yard container handling machines. An RMG travels on rails to lift and stack 20, 40 and other iso containers in the yard area of the container terminal. The container islifteby a spreader attached to cables.
Rail mounted cranes come in a variety of models with different spans and overhangs.
The Gantry Crane may be single girder or double girder depends upon the capacity and duty of the Overhead Crane.The bridge of gantry overhead crane installed on its four pillars and the pillars are attached with the end carriages that move with the bridge on the rail.The rail is fitted on the floor level. The power supply may be single phase or 3 phase depending upon the duty of the crane. The electrical system consists of cable reeling drum and Festoon system attached to the bridge.We have different capacities of gantry overhead cranes ranges from 500 kg to 100000 kg with different overhead crane duties
Advantages
1)Higher hook lift, since the hook can be pulled up between the main girders.
2)Extremely rigid box girder construction and durable trolley design are well suited for heavy service applications.
3)Economical material handling in those area where overhead crane system is not easily available
4)Safe and efficient
5)Easy installation and maintenance
