Rubber-Tired Gantry Crane
Trackless, project-engineered lifting and transport for factories, precast yards, steel plants, wind-energy production, modular construction and other sites where heavy or oversized loads must move without a fixed rail runway.
Rubber-tired gantry crane configured for flexible, rail-free movement in an industrial handling area.
Henan Mine Crane rubber-tired gantry cranes combine a load-bearing gantry, hoisting system and rubber-tired travel system in one mobile handling platform. Unlike a conventional rail-mounted gantry crane, the equipment can be engineered to move between work zones and serve changing production, storage and loading routes.
Capacity alone is not enough to select this equipment. The correct configuration depends on the complete suspended load, load dimensions, center of gravity, lifting points, required clear width, travel route, turning space, pavement capacity, operating frequency, power concept and environmental conditions. Parameters that have not been confirmed for a specific project are therefore identified as project-specific rather than assumed.

Product Overview
A rubber-tired gantry crane is both a lifting machine and a mobile transport system. Its gantry structure supports the suspended load, while the rubber-tired travel and steering systems allow the crane to move across prepared factory floors or outdoor yards without fixed rails. This makes it suitable for operations where loads must travel between production, inspection, storage and dispatch areas.
The equipment may be configured as an A-frame mobile gantry, double-beam rubber-tired gantry, industrial straddle carrier or a specialized handling platform. The most suitable form depends on whether the crane must travel over the load, lift from outside the load envelope, work under restricted headroom, pass through doors or turn inside narrow yards.
Before quotation, provide the maximum load drawing and a complete site route plan. Henan Mine Crane can then evaluate lifting capacity, structural clearance, steering geometry, ground loading, braking, duty and power requirements as one integrated system.
Why Choose a Rubber-Tired Gantry Crane?
Trackless Mobility
The crane is not limited to one fixed runway. A correctly engineered travel and steering system can serve multiple pickup, storage and loading points within the approved route.
Lower Rail-Infrastructure Dependency
Projects can avoid a continuous rail path, although the floor, pavement and ground structure must still be verified for loaded tire and axle reactions.
One Machine for Lifting and Transport
The same equipment can pick a load, move it through the approved route and position it at the destination, reducing intermediate transfers between separate lifting and transport machines.
Configured Around the Actual Load
Clear width, lifting height, spreader, lifting points and structural form can be engineered for long, wide, high or irregular loads that standard handling equipment cannot accommodate.
Flexible Production Layout
Rubber-tired travel is relevant where production routes, storage locations or project stages may change, provided every intended route is included in the engineering review.

How to Select the Right Rubber-Tired Gantry Crane
1. Calculate the Complete Suspended Load
Include the heaviest load plus the spreader, lifting beam, slings, hooks and any permanent attachment. Do not select capacity from the cargo weight alone.
2. Provide the Load Envelope and Center of Gravity
Maximum length, width, height, center of gravity and lifting-point coordinates determine the gantry clearance, load attachment and stability review.
3. Map the Complete Travel Route
Show the narrowest aisle, door openings, corners, intersections, slopes, overhead obstructions, pickup points, placement points and parking area.
4. Verify Ground and Pavement Capacity
The complete loaded crane mass is transferred through a limited number of tires. Final tire and axle reactions must be checked against every section of the intended route.
5. Define Duty and Productivity
Provide moves per hour, hours per shift, shifts per day, loaded travel distance and load spectrum so the hoisting, drive, braking and maintenance strategy match real production.
6. Select the Operating Concept
Visibility, personnel access, route complexity and positioning accuracy determine the appropriate operator location, control functions and warning system.
7. Confirm Power and Environmental Requirements
Site utilities, travel range, emissions limits, operating time, outdoor exposure and local electrical conditions must be reviewed before the drive and power architecture is finalized.

Safety & Control: What Buyers Should Confirm
• Rated-capacity and overload protection based on the complete suspended load
• Load stability during lifting, loaded travel, steering, braking and placement
• Hoisting limits, synchronization monitoring and emergency-stop functions where applicable
• Service braking, parking braking and safe holding on the approved route gradients
• Operator visibility, cameras, audible / visual warnings and restricted-zone management
• Tire condition, inflation / solid-tire requirements, wheel assemblies and axle-load verification
• Anti-collision, obstacle detection or positioning assistance where required by the risk assessment
• Outdoor wind monitoring, storm parking and weather protection where applicable
• Factory and site acceptance tests covering lifting, travel, turning, braking and safety functions
Installation, Commissioning & Maintenance
Before manufacture, freeze the load drawings, lifting points, route layout, minimum clearances, surface conditions, pickup / placement positions, operating cycle, applicable standard and site acceptance criteria. Because the equipment travels on tires, route readiness is part of installation planning even when no rail runway is required.
Commissioning should verify the crane on the approved route under the conditions defined in the technical agreement. Testing normally needs to cover lifting functions, loaded and unloaded travel, steering, alignment, stopping, parking, safety devices, warning systems and any required positioning or productivity targets.
Maintenance planning should include the hoisting system, ropes or chains where fitted, spreader, brakes, tires, wheel and axle assemblies, steering components, drive system, structural connections, controls and safety devices. Buyers should confirm service access, inspection intervals, recommended spare parts and local technical support before purchase.

Frequently Asked Questions
What is the difference between a rubber-tired gantry crane and a rail-mounted gantry crane?
A rubber-tired gantry crane travels on tires and is not limited to a continuous fixed rail route. A rail-mounted gantry crane follows installed rails and serves a defined runway. The better choice depends on layout flexibility, duty, positioning, infrastructure and lifecycle requirements.
Is every RTG crane designed for container handling?
No. RTG is also used for industrial rubber-tired gantries and straddle carriers handling precast components, steel structures, wind-energy parts, modular buildings and other oversized loads. Container service requires a container-specific spreader, stacking layout, duty and control system.
What determines the correct lifting capacity?
Use the maximum complete suspended load: cargo plus spreader, lifting beam, slings, hooks and any other attachment carried by the hoisting system.
Why is a route drawing required before quotation?
The crane must safely carry the load through the actual site. Aisle width, turning space, door openings, slopes, pavement and traffic interfaces can change the steering system, dimensions, tire loading, drive power and final price.
Can the crane be customized for irregular loads?
Yes, but the buyer must provide reliable load drawings, center-of-gravity data, lifting points and allowable reactions. The gantry clearance and lifting attachment are then engineered around those inputs.
What factors affect rubber-tired gantry crane price most?
Major cost drivers include lifting capacity, clear width, lifting height, structural form, steering requirements, tire and axle loading, spreader, duty, travel distance, control and power system, environmental protection and commissioning scope.
What should be included in the site acceptance test?
The technical agreement should define lifting, loaded travel, unloaded travel, steering, braking, parking, safety devices, warnings and any positioning or cycle-time requirements that are critical to the project.
