What is a Rubber-Tyred Beam Lifting Gantry Crane?
A rubber-tyred beam lifting gantry crane functions as a heavy-duty mobile industrial lifting machine operating on pneumatic tires. Precast concrete contractors utilize this versatile straddle carrier to hoist, transport, and position massive bridge beams. It guarantees exceptional maneuverability across rugged construction yard terrain globally.
Equipment Overview
A rubber-tyred beam lifting gantry crane revolutionizes massive concrete yard logistics significantly. Operators maneuver the heavy duty RTG crane for precast beams flawlessly across rugged fabrication terrain. We integrate advanced independent steering into every pneumatic tire beam lifter. This mobile straddle carrier for concrete beams executes precise zero-radius turns effortlessly. Your logistics teams handle colossal bridge segments securely utilizing the rubber-tired gantry lifting machine. The high-capacity RTG crane maximizes daily production throughput during demanding bridge construction schedules continuously. Engineers guarantee absolute structural stability during continuous heavy dynamic lifting operations.

High-power diesel generators drive closed-loop hydraulic travel motors directly. This machinery conquers steep gradients smoothly.
Dynamic Safety Monitoring
Precision inclinometers monitor chassis tilt continuously during complex transport maneuvers. The central controller restricts speeds automatically.
Customizable Beam Spreaders
Adjustable lifting spreaders secure varying concrete box girder dimensions perfectly. Technicians modify the clamp profile quickly.
Frequently Asked Questions
How does the steering system maneuver massive payloads within constrained precast casting yards?
The machine utilizes independent hydraulic wheel suspension modules. These modules rotate exactly 90 degrees simultaneously, enabling crab steering and center-pivot rotation. Operators move massive girders sideways into tight storage slots precisely.
What ground bearing pressure do the pneumatic tires exert during maximum load transport?
The active hydraulic suspension distributes weight optimally across multiple heavy-duty tire groups. This configuration minimizes ground pressure below 0.6 MPa, protecting temporary fabrication yard foundations from critical structural damage effectively.
Can the hoisting mechanism adjust unbalanced girder center of gravity issues safely?
Yes. The synchronous control system allows micro-adjustments on individual lifting points. Operators correct longitudinal and transverse weight imbalances precisely before executing full payload suspension.
How does the equipment maintain steady traction on steep construction site gradients?
Closed-loop hydraulic travel motors power multiple wheel groups directly. This direct-drive configuration ensures continuous torque delivery. It prevents dangerous wheel slip on longitudinal slopes up to 5%.
What redundant safety systems protect operations during high-wind coastal lifting scenarios?
Integrated digital anemometers monitor wind speeds continuously. The central PLC triggers immediate operational lockouts and engages heavy-duty mechanical wheel brakes when wind gusts exceed pre-programmed safety thresholds.
What is the typical lead time for delivery?
Standard lead time is 30-45 days depending on configuration and current production schedule. We provide a firm delivery date with every quotation.
Do you provide installation and commissioning support?
Yes. Our engineering team can travel to your project site to supervise installation, provide training for your crew, and commission the equipment. Remote video support is also available.
What warranty do you offer?
All our structural equipment comes with a 10-year structural warranty and 2-year comprehensive warranty covering manufacturing defects. Extended warranty options are available.
What shipping methods are available?
