Rail Mounted Gantry Crane

Product Introduction

The rail mounted 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. 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 control with 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 standards and international standards such as FEM, DIN, IEC, AWS, etc. Weihua’s RMG has the characteristics of multiple functions, stability, reliability, a wide range of operation, easy operation, and maintenance.

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

Rail Mounted Gantry Crane Components

Rail mounted gantry crane mainly consists of a metal structure (main beam, outrigger, traveling cart), hoisting mechanism, trolley running mechanism, trolley running mechanism, electrical control system, and safety protection devices.

Parts Show

Gantry frame

Lifting trolley

Trolley operating mechanism

Mobile drivers cab

Crane power supply and trolley feed mode

Electrical protection

Platform&ladder

Container Spreader

Main beam: box or truss structure, supporting the hoisting mechanism and trolley running.
Outrigger: rigid support structure, connecting the main beam and traveling cart, transferring the load to the rail, ensuring the stability of the whole machine.
Traveling cart: drive the crane to move along the track, equipped with a motor, reducer, and wheel set to realize accurate positioning and efficient operation.
Hoisting mechanism: composed of motor, drum, wire rope, and container spreader, responsible for vertical lifting and lowering of containers, with speed regulation and anti-shaking function.
Trolley running mechanism: drives the spreader to move horizontally along the main beam, adopting frequency conversion control to realize smooth loading and unloading and accurate alignment.
Electrical control system: integrating PLC and frequency conversion technology, coordinating the action of each organization, supporting automatic operation, and fault monitoring.
Safety protection devices: including limiters, overload limiters, and windproof anchors to ensure the safety of the whole machine.

Features

Operational efficiency

The rail mounted gantry crane use electronic anti roll systems, some major foreign professional companies are developing fully automatic unmanned container anti roll positioning systems with positioning feedback devices to improve operational efficiency.

Large span

To accommodate container ships of different sizes, RMGs could cover multiple berths and even span multiple railway tracks.

Track type

Due to the use of track type, the rail type mounted gantry crane can withstand greater loads by increasing the number of wheels. Therefore, the span of the rail mounted container gantry crane increases.

Flexibility

In addition to basic vertical lifting and horizontal movements, some advanced RMGs can also perform rotational operations, further enhancing operational flexibility.
