Container Gantry Crane RMG Type

　　The rail mounted container gantry crane is applicable to remove, load and unload international standard containers. It is a highly efficient loading and unloading equipment, mainly for in ports, docks and inland container yards. The main function is stacking, handling and transshipment of containers from ships to land transport. The main beam is the core structure that bears the weight of the container. And it is usually a box-shaped section to ensure strength. Its outriggers connect to both ends of the main beam. Thus, it could support the entire RMG crane and allow it to move along tracks on the ground.

　　The electric drive adopts the unique technology of full digital AC frequency conversion and PLC speed regulation controlwith flexible control and high precision. Standard bought-in components from well-known brands at home and abroad ensure overall quality.

　　The design, manufacture and inspection comply with Chinese standard and international standards such as FEM, DIN, IEC, AWS and etc. Weihua’s RMG has the characteristics of multiple function, stability, reliability, wide range of operation, easy operation and maintenance.

　　Our main products include upper rotating (trolley rotation) RMG, lower rotating (spreader rotation) RMG, cantilevered and non-cantilevered RMG, RMG for railway.

　　Structure

　　Rail mounted container gantry crane is appropriate for handling, loading and unloading ISO container and railway wide containers. With multiple steel wheels and electricity power, it consists of gantry mechanism, trolley assembly, gantry frame, power system and special container spreader.

　　The rail type mounted container gantry cranes are divided into different forms based on the structure of the main beam and supporting legs.(1) The double cantilever track container gantry crane requires the container to pass through the inner space of the two side door legs. So the width direction clearance inside the door legs is relatively large. Depending on the form of main beam, double cantilever RMG generally adopts a "U" shape with the upper part of the door legs. And there is a "π" shape with the upper part of the door legs. The structure of the cantilever track type is relatively simple because there is no need passing through the space inside the door legs.(2) Compared to shore mounted container cranes, RMG gantry crane have lower trolley speeds and generally do not have anti roll devices. If users request to reduce operational intensity and improve productivity, we could install anti roll devices. For rope type lifting mechanisms, roll reduction could achieve by applying damping to the ropes. For rigid lifting mechanisms, roll reduction generally achieves through rigid components.
