MH Single-Girder Gantry Crane — A Proven Choice for Light to Medium Lifting

The MH single-girder gantry crane is one of the most widely used types of lifting machinery. Its hoisting mechanism is an electric hoist, and the crane travels on rails on the ground, supported by legs on both sides. In general working conditions it loads, unloads and handles materials and equipment in an intermittent and repetitive way, with vertical lifting as well as longitudinal and lateral travel. Cantilevers can be fitted on the outer side of the legs so that goods can be transferred from one bay to outside the span; they can also be left out.

Key Features of the MH Gantry Crane

Mature design, reliable performance

The MH single-girder gantry crane uses a mature single-girder gantry structure and is normally matched with CD or MD series electric hoists. Its structural design, manufacturing process and component supply system are widely proven, and it suits general material handling where lifting capacity, span and operating frequency stay within the normal range. The high degree of standardisation also makes selection, manufacture, installation and commissioning straightforward.

Simple maintenance, low running cost

The hoisting, travelling and electrical systems mostly use common configurations and the parts are highly interchangeable, so routine inspection, replacement of wearing parts and troubleshooting are relatively convenient.

Light total mass, lower wheel pressure and foundation requirements

With a single main girder and an electric hoist as the hoisting mechanism, the MH single-girder gantry crane has a comparatively light total mass.

Applications of the MH Gantry Crane

The MH single-girder gantry crane can be used in workshops, storage yards, warehouses and other outdoor sites for general lifting within the light to medium capacity range. It must not be used in environments with flammable, explosive or corrosive gases. Actual selection depends on the weight of the goods, the lifting attachments, the working area and the operating environment.

Box Girder vs Trussed Gantry Crane

mh box girder gantry crane 1 — Box girder MH gantry crane

Structure: closed box-section main girder, steel plates welded into a closed box.

Caractéristiques : good box-girder workmanship, working class up to A5, easy installation and maintenance.

Applications: factories, warehouses and open-air sites with frequent operation.

mh trussed gantry crane watermarked — Trussed MH gantry crane

Structure: open truss main girder, structural steel or steel tubes welded into a triangular lattice.

Caractéristiques : lighter total mass, strong wind resistance, working class usually A3, lower price.

Applications: open-air storage yards with strong wind and sites sensitive to equipment weight.

Case Study: 10 t Gantry Crane for Precast Concrete Handling in Mauritius

A concrete products manufacturer in Mauritius needed outdoor lifting equipment next to its existing workshop, to lift precast drainage pipes and other concrete elements out of the moulds and transfer them to the next process or to the outdoor storage area. The span, travel route and rail length were determined from the workshop position, the vehicle access and the element storage area, and production then began.

Project configuration:

Lifting capacity: 10 t
Span: 12 m
Lifting height: 4 m
Travelling distance: 30 m
Power supply: 400 V, 50 Hz, three-phase AC
Power feed: cable and cable reel
Unit price per gantry crane: US$18,064

The customer planned to install the crane itself. The project therefore also provided rail and foundation layout requirements, equipment assembly documents, electrical connection instructions, a reference video and remote technical guidance. A configuration made up of a proven crane structure, a standard electric hoist and a standard travelling mechanism is convenient for a local team to install, and it also helps with later inspection, maintenance and replacement of wearing parts.

The case reflects the value of the MH single-girder gantry crane as a general solution: where the working conditions are clear, the lifting capacity is moderate and no special hoisting mechanism is required, a proven configuration can be used for the equipment selection, and the specific parameters are then adjusted to the actual span, travel distance, power supply and installation conditions — without adding unnecessary structural complexity for ordinary working conditions.
