MHhs Electric Hoist Single Girder Gantry Crane
Product Introduction
The MH Type Electric Hoist Gantry Crane (also known as MH Type Single Girder Gantry Crane or Hoist Gantry Crane) mainly consists of the gantry frame (main girder, legs, and bottom cross beam), hoisting mechanism, travel mechanism, and electrical control system. It utilizes a CD1/MD1 type electric hoist as the hoisting mechanism, making it the most widely used rail-mounted gantry crane for light to medium lifting capacities. Lifting capacity ranges from 1 to 20 tons, span from 7.5 to 30 meters, and lifting height from 6 to 30 meters. The working environment is -20℃ to +40℃.
The gantry frame is available in two configurations: box girder and truss girder. The box girder offers superior fabrication quality and ease of manufacturing, while the truss girder provides lighter dead weight and better wind resistance. The crane can be customized with a single-end cantilever or without cantilever based on customer requirements. This crane is not suitable for lifting molten metal or flammable/explosive materials.

Working Principle
The electric hoist traverses laterally along the I-beam rail on the main girder (cross travel / trolley travel), while the crane travel mechanism moves longitudinally along the ground crane rail (long travel / bridge travel). The hoisting mechanism lifts and lowers loads through the CD1 type conical rotor motor, which drives the drum wire rope and hook through a three-stage deceleration gearbox. The entire crane is centrally controlled via the electrical control box, allowing independent or simultaneous operation of the hoisting, trolley travel, and bridge travel mechanisms.

MH Type Electric Hoist Gantry Crane Dead Weight and Main Girder Configuration
| Parameter | 1t | 2t | 3t | 5t | 10t | 16t | 20t |
| Box Girder Dead Weight(Approx.) | ~4t | ~5.5t | ~7t | ~9t | ~14t | ~20t | ~25t |
| Truss Dead Weight(Approx.) | ~3.2t | ~4.5t | ~5.5t | ~7t | ~11t | ~16t | ~20t |
The parameters above are reference values for standard configurations. The dead weight of the box girder and truss girder is estimated based on a 12m span; actual values are determined by span, lifting height, and other factors.
Typical Applications
- Industrial yards and freight stations: General loading, unloading, and handling operations.
- Open-air warehouses: Stacking and transfer of packaged goods.
- Factory workshops: Assembly and maintenance of medium and small-sized equipment.
- Logistics transfer hubs: Cargo loading, unloading, and transshipment.
Selection Guide
Box Girder: Suitable for general working conditions. The manufacturing process is mature with short lead times, making it the recommended choice for conventional indoor and outdoor freight yards.
Truss Girder: The truss (lattice) girder is 15%~25% lighter in dead weight and offers lower wind resistance (smaller wind load). Recommended for large-span outdoor applications and coastal areas with significant wind loads.
Reference Price: 1~5t: 40,000~100,000 CNY; 5~10t: 100,000~200,000 CNY; 10~20t: 200,000~400,000 CNY.
Operating Instructions
Pre-operation Checks: Ensure the crane rail is clear of obstructions, the wire rope is in good condition, the brake functions properly, and the limit switch is responsive.
Operation: Perform a no-load test run to confirm all mechanisms are functioning correctly. Conduct a trial lift of 200mm to verify braking reliability. Overloading and skewed or angled lifting are strictly prohibited.
Shutdown: Raise the hook to the upper limit, return the controller to the zero position, and disconnect the main power supply.

FAQ
Q: How do I choose between a box girder and a truss girder gantry crane?
A: The box girder features a mature manufacturing process, is easier to produce, and has a clean appearance, making it suitable for conventional indoor and outdoor freight yards. The truss girder (lattice type) is 15%~25% lighter and offers better wind resistance, making it ideal for large-span outdoor applications and coastal regions. In terms of price, the box girder is slightly lower than the truss girder.
Q: Which national standards does the MH type electric hoist gantry crane comply with?
A: It is designed and manufactured in accordance with JB/T 5663-2008 "Electric Hoist Gantry Crane" standard. The main girder design follows GB/T 3811 "Crane Design Standard," and safety protection complies with GB 6067 "Safety Rules for Lifting Appliances."
