MH Type Gantry Crane with Truss Single Girder
Product Introduction
The MH Type Open-Web Single-Girder Gantry Crane (also known as the MH Type Truss Gantry Crane) features a truss (open-web) main girder structure that offers low dead weight, reduced wind resistance, and strong wind stability, making it particularly well-suited for large-span outdoor applications. Paired with the CD1/MD1 Electric Hoist, it provides a Lifting Capacity of 1–20 tons, a Span of 12–30 meters, and operates in a Working Environment of -20°C to +40°C.
Additional variants are available, including the MH Type with top-enclosed/bottom-open-web configuration, MH Type Box Girder, MHE Type with dual Electric Hoists, BMH Type Semi-Leg, and MHY Type High Temperature Resistant for metallurgical applications.

The open truss girder design minimizes wind resistance, making it ideal for large-span outdoor operations. Product Features
- Lightweight Open-Web Main Girder: The truss structure saves 15%–25% on Steel compared to a box girder, reducing foundation costs.
- Superior Wind Resistance: The open truss design results in low wind load, suitable for outdoor and coastal areas.
- Multiple Series Coverage: Available in MH/MHE/BMH/MHY and other variants.
- Floor/Indoor Dual Control: Two control options available.
- Short Lead Time: Standardized design ensures delivery within 15–20 days.
- Nationwide Supply: Pickup or freight forwarding available, with a one-year warranty.
Working Principle
The truss main girder forms a stable triangular structure consisting of top chord, bottom chord, and web members. The crane bridge moves longitudinally along ground rails, while the Electric Hoist traverses laterally along the main girder. The CD1 type Conical Rotor Motor drives the three-stage Deceleration mechanism to raise and lower the Hook via the drum Wire Rope.

FAQ
Q: What is the difference between a truss girder and a box girder gantry crane?
A: The truss (lattice) girder is 15%–25% lighter in dead weight and offers better wind resistance, making it ideal for large-span outdoor applications. The box girder provides superior rigidity and a cleaner appearance, better suited for indoor heavy-duty applications.
Q: Which national standards does the MH Type truss gantry crane comply with?
A: Designed to JB/T 5663-2008, with the truss structure referencing GB/T 14406-2011 and the hoisting mechanism complying with JB/T 9008.1.
Q: What are the advantages of choosing Kelude Heavy Industry for truss gantry cranes?
A: Kelude Heavy Industry is based in Xinxiang, Henan, with over a decade of experience in gantry crane manufacturing. Truss members undergo internal force analysis per GB/T 3811 Crane Design Standard, and node weld seams are inspected by UT non-destructive testing.
