MHhs Rubber Tired Gantry Crane for Versatile Heavy Lifting
Product Introduction
MHhs Type Rubber-Tyred Gantry Crane (also known as MH Type single-girder rubber-tyred crane or rubber-tyred gantry crane) features a rubber-tyred travel mechanism instead of the traditional crane rail-mounted bridge, enabling trackless free movement on level ground. With a lifting capacity of 1–20 tons, a span of 8–20 meters, and a lifting height of 6–30 meters, the crane integrates mechanical, electrical, and hydraulic systems with microcomputer control technology. Both hoisting and travel are powered by a hydraulic drive system, making it ideal for trackless mobile hoisting applications in precast yards, batching plants, and storage yards.
The rubber-tyred gantry crane supports four travel modes: straight travel, diagonal travel, transverse travel, and in-situ slewing. During heavy-load steering, support cylinders act on the ground to reduce tire ground pressure and minimize ground shear damage. It can handle slopes up to ±5%.

Product Images
The image above shows the MHhs Type Rubber-Tyred Gantry Crane in actual operation. Its rubber-tyred travel mechanism allows trackless free movement within precast yards, batching plants, and similar sites.
Product Features
- Trackless Free Movement: Rubber-tyred travel mechanism requires no crane rail, allowing unrestricted movement on hardened ground.
- Four Steering Modes: Straight, diagonal, transverse, and in-situ slewing for exceptional site adaptability.
- Hydraulic Drive System: Both hoisting and travel are hydraulically driven; support cylinders engage the ground during heavy-load steering to protect the tires.
- High Slope Capability: Handles site slopes up to ±5%, suitable for non-level precast yards.
- Multi-Scenario Coverage: Ideal for handling rebar cages/formwork in precast yards, batching plants, storage yards, and more.
- Flexible Customization: Span of 8–20 m and lifting height of 6–30 m can be tailored to specific requirements.
Working Principle
The hydraulic pump station serves as the power source, driving the rubber-tyred travel and hoisting drum via hydraulic motors. The travel system uses independent wheel-mounted hydraulic motors with electro-hydraulic proportional control to achieve four-wheel synchronization or differential steering, enabling straight, diagonal, transverse, and in-situ slewing movements. During load handling, hydraulic outrigger cylinders support the ground to reduce tire load. The electrical control system features PLC plus wireless remote control, allowing the operator to perform all operations from a safe distance.

Operating Instructions
Site Requirements: The site must be hardened and level, with a slope of ≤±5%, and the ground bearing capacity must meet the tire contact pressure requirements.
Operation: Start the hydraulic pump station and allow 3~5 minutes for preheating. Perform a no-load test run to confirm all mechanisms are functioning properly. When turning under load, extend the outrigger cylinders to contact the ground first. Overloading is strictly prohibited.
Maintenance: Periodically inspect the hydraulic oil level and filter elements, tire pressure and wear, and lubrication of all pivot points.

FAQ
Q: What is the difference between a rubber-tired gantry crane and a rail-mounted gantry crane?
A: A rubber-tired gantry crane uses a tire-based travel mechanism and requires no crane rails. It can move freely on hardened ground, supporting four modes: straight travel, diagonal travel, lateral travel, and in-situ slewing. A rail-mounted gantry crane requires crane rails and has a fixed travel path. Rubber-tired models are better suited for rail-free applications like precast yards and batching plants that require frequent repositioning, but their lifting capacity and span are generally smaller than those of rail-mounted units.
Q: Which national standards does the MHhs type rubber-tired gantry crane comply with?
A: It is designed in accordance with JB/T 5663-2008 "Electric Hoist Gantry Crane" standard. The hydraulic system complies with GB/T 3766 "Hydraulic fluid power - General rules for the application of equipment to transmission and control systems," and safety protection meets the requirements of GB 6067 "Safety rules for lifting appliances" and TSG Q0002.
