MH Single Girder Gantry Crane（Truss Type）

The MH single girder gantry crane (truss type) adopts a truss structure design and consists of the main beam, support legs, bottom beam, traveling mechanism, hoisting mechanism, and electrical system. It is a light to medium-duty rail-mounted crane. The main beam and support legs are welded from angle steel, channel steel, or steel pipes. The hoisting mechanism uses a CD1/MD1 electric wire rope hoist, paired with a traveling trolley that runs back and forth along the lower flange of the main beam. The main control methods include pendant control, wireless remote control, and cabin operation. The whole crane features a compact structure, light deadweight, strong wind resistance, and easy installation and maintenance.

The MH single girder gantry crane (truss type) is highly suitable for windy outdoor locations, such as ports, mines, factories, logistics parks, and construction sites.

Note: Lifting capacity, span, lifting height, lifting speed, traveling speed, power supply, and operation mode can all be customized.

Features of Truss Type Single Girder Gantry Crane 

Strong wind resistance: The truss structure effectively reduces wind load, and the wind resistance performance is improved by 30% compared with box-girder cranes of the same class.

High safety performance: Standard equipped with wind-proof rail clamps and anchoring devices, with optional wind-resistant tie-down cables and wind monitoring and warning devices, meeting the safety operation requirements in windy outdoor environments.

Light deadweight and low infrastructure cost: The deadweight of the equipment is 15%–25% lighter than that of box-girder cranes of the same class, greatly reducing the requirements for site foundations.

Low procurement cost: The truss structure features a simple manufacturing process, and material consumption is 20%–40% less than that of box-girder cranes, resulting in a lower procurement cost than box-girder cranes of the same class.

Modular design: The whole crane adopts a modular structure, with components that are easy to disassemble and assemble, making transportation and installation convenient, and facilitating maintenance and component replacement.

Stable structure and long service life: The main beam and support legs are welded from high-quality steel, ensuring overall stability and durability. The structural deformation is lower than industry standards, providing safe and reliable long-term operation.

Applications of Truss Type Single Girder Gantry Crane

Ports and Logistics Yards：Lifting of containers, steel, pipes, and other cargo.

Mines and Quarries：Lifting of ore, slag, and mining equipment parts.

Factories and Industrial Workshops：Handling of equipment, parts, various raw materials, or finished products.

Construction Sites：Handling of construction materials such as rebar, formwork, steel beams, and precast components.

Steel storage yards:  used for lifting light to medium steel materials such as steel plates, steel pipes, and structural steel.

Railway freight yards:  used for lifting cargo, containers, bulk cargo, etc.

 

Main girders

Truss design, welded from structural steel (angle steel / steel pipe), featuring a robust structure and light deadweight. Its wind resistance is improved by 30% compared with box-girder cranes of the same class.

 

Legs

Truss-type or box-type welded structure, connected to the main beam and bottom beam with high-strength bolts to ensure operational stability of the equipment.

 

Hoisting mechanism

Standard equipped with CD1 (single-speed) or MD1 (dual-speed) electric wire rope hoists, suitable for medium and light duty classifications, with smooth operation to meet conventional lifting accuracy requirements.

 

Electrical system

Uses electrical components from globally renowned brands. All circuits are provided with overload, short-circuit, and phase-loss protection, centrally arranged in a sealed electrical cabinet with dustproof, waterproof, and corrosion-resistant performance.

To select the correct single girder truss gantry crane, the following project information should be defined during the inquiry stage:

1. Rated lifting capacity and the maximum weight of the actual load including rigging

2. Required span between runway rails and available runway length

3. Lifting height from ground level to hook position

4. Indoor or outdoor installation, including local wind conditions if outdoor

5. Work duty or estimated operating hours per day and load spectrum

6. Available power supply voltage, frequency, and phase

7. Preferred control mode: pendant, remote, or cabin

8. Site rail type and foundation design if already existing

9. Optional features such as rain canopy, lighting, warning systems, or special corrosion protection

Based on these inputs, Yufei Crane provides a general arrangement drawing, wheel load report, foundation load data, and a technical datasheet for approval before manufacturing.

Yufei Crane supports the full project cycle from engineering to commissioning. Our scope of supply includes:

1. Custom structural and electrical design based on site conditions and international standards

2. In-house fabrication of truss girders, legs, end carriages, and control panels

3. Pre-assembly and load testing before packaging and transportation.

4. Export-grade packaging suitable for sea, rail, and road transport

5. Installation supervision and commissioning by qualified engineers or authorized local partners

6. Operator training, maintenance training, and handover documentation
