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
Higher hook lift, since the hook can be pulled up between the main girders.
Extremely rigid box girder construction and durable trolley design are well suited for heavy service applications.
Economical material handling in those area where overhead crane system is not easily available
Safe and efficient
Easy installation and maintenance
Weight overload protection devices
Emergency stop system
Hooks with latch
High quality rubber buffers
Crane switch and travel end switch
Current overload protection function
1. The box-shape gantry is made of well-chosen steel and processed by advanced technology, so the gantry is of high intensity, rigidity, toughness and long life. On the gantry are laid the rails for cross travel and electrical cabinet. Cantilevers can be added for wider work range.
2. The trolley is comprised of motors for lifting and travelling, brake, reducer, coiling block and electric power transmission device. Weather enclosure is set up to protect the inside components from wastage because of weather. The trolley traverses along the rails laid on the gantry for cross travel.
3. Electric parts adopt international brand Schneider and Siemens to ensure accurate operation, excellent performance and convenient maintenance.
4. There are two control methods for choice, namely cabin control and ground control.
