MG General-Purpose Gantry Crane

Product Introduction

The MG General-Purpose Gantry Crane is a hook-equipped double-girder gantry crane designed for general lifting, loading, unloading, and material handling operations in outdoor storage yards and along railway lines.

The crane features a box-type welded bridge structure and a gantry travelling mechanism with separate drives. It is operated from an operator’s cabin, allowing the lifting, trolley travelling, and gantry travelling mechanisms to work together for material handling operations.

The MG crane is available in 5-ton and 10-ton lifting capacities, with multiple span and lifting height options. Depending on site requirements, the crane can be equipped with either a cable power supply system or a conductor rail system.

Working Principle

The MG General-Purpose Gantry Crane performs lifting and material handling through the coordinated operation of its hoisting mechanism, trolley travelling mechanism, and gantry travelling mechanism.

The hoisting mechanism raises and lowers loads using the lifting hook. The trolley travelling mechanism moves the hoisting assembly horizontally along the bridge girders, positioning the load across the working area.

The gantry travelling mechanism moves the entire crane along the ground-level rails, allowing loads to be transported longitudinally across the outdoor working area. The mechanism adopts separate drives, and all operating functions are controlled from the operator’s cabin.

The coordinated movement of these mechanisms enables loading, unloading, transportation, and positioning operations in outdoor storage yards and railway-side facilities.

Applications

The MG General-Purpose Gantry Crane is suitable for:

• Outdoor storage yards
• Railway-side loading and unloading areas
• Industrial material handling facilities
• Outdoor warehouses
• General cargo lifting and transportation
• Material transfer and storage operations
• Industrial sites requiring rail-mounted gantry cranes

It is particularly suitable for general lifting and material handling tasks in outdoor storage yards and along railway lines.

OEM & Customization

Chunhua provides crane solutions according to project-specific requirements.

The MG General-Purpose Gantry Crane can be selected or configured according to:

• Lifting capacity
• Span and site layout
• Required lifting height
• Hoisting and travelling speeds
• Working duty and operating frequency
• Power supply arrangement
• Rail selection
• Operating temperature range
• Electrical and control requirements
• Material-handling requirements

When placing an order, customers should specify the minimum and maximum ambient operating temperatures, power supply conditions, and preferred power supply arrangement, either cable-based or conductor rail-based.

The final configuration should be confirmed according to the actual application, site conditions, and technical requirements.
