30 Ton Rubber Tyred Gantry Crane Ready for Singapore

The 30 ton rubber tyred gantry crane for sale to Singapore is used for open yards for heavy loads handling for airport construction.

Our customer runs a huge material storage yard right next to one of Singapore's busiest container terminals. The complex spans over 10 hectares and includes covered and open stacking areas, heavy-duty tarmac capable of sustaining fully loaded vehicles, and direct rail and road connectivity for smooth inbound and outbound operations.

Customer Needs & Pre-Existing Challenges

The customer needed a crane that could handle and manage large building materials such as prefabricated steel structure modules, massive concrete panels, and bundled pipe sections across multiple parallel stacking lanes. They need a system with a high load rating to safely lift these dense components, fast cycle times to meet tight project deadlines, and pinpoint positioning precision to exactly align each item within limited storage rows. This combination of strength, speed, and control was critical for increasing yard density and improving material flow from delivery to on-site deployment.

Operational Limitations Before RTG

Prior to using the RTG crane, the yard had several operational bottlenecks. Forklifts could only reach five-tier stacks, leaving nearly 18% of storage volume unused. Loads above that capacity required mobile cranes, which took about five minutes to set up, reposition, and break down, causing schedule delays. During the monsoon season, waterlogged and uneven ground made forklift operations dangerous, causing tip-overs.

Product Solution: 30T Rubber‑Tyred Gantry Crane

Structural Design & Mobility

The RTG crane has a strong double-girder steel frame that can be configured for any span between 10 and 35 meters. Each end truck has eight or sixteen heavy-duty pneumatic rubber tires, which distribute the 30 t load uniformly and eliminate the need for permanent rails. Hydraulic steering on all bogies gives tight 360° turning capability, allowing you to move the crane anywhere in the yard—between storage lanes, along container rows, or around obstacles—without requiring ground preparation. The open-frame design also decreases wind loads, allowing the crane to stay stable even in stormy outdoor circumstances.

Hoist, Power & Controls

• Capacity: The RTG crane's hoist can raise loads weighing up to 30 tons to heights of 10 meters. This range can handle complete container stacks and hefty material bundles without requiring intermediary rigging changes.
• Drive Options: For off-grid operation, the crane comes equipped with a diesel-electric power unit as standard. Choose the full-electric model if your yard requires reliable grid access or zero emissions. Both drives connect easily into the crane's control framework.
• Hoist speed: The empty-hook travel speed is 12 meters per minute, allowing you to quickly reposition the hook. Under full load, the hoist speeds to 23 meters per minute, maximizing productivity while maintaining safe pull and rope tensions.
• Travel speed: The crane travels around the yard at speeds of up to 20 meters per minute. Inverter-driven acceleration and deceleration result in smooth starts and stops, eliminating tire scrub, structural stress, and load jerk.
• Safety systems: Built-in sensors include anti-collision radars at each bridge end, obstacle detection units throughout the frame perimeter, and anti-skew sensors on all tire bogies to ensure straight transit. Overload indicators monitor hoist current draw and notify operators when loads near capacity limits.
• Environmental protection: The crane's double-girder frame is reinforced with cross bracing and torsion-resistant parts to handle strong winds and twisting pressures. All electrical cabinets and hydraulic lines have weatherproof enclosures and seals to protect against rain, dust, and salt-air damage.

Safety Systems & Environmental Protection

Anti-collision sensors on the bridge ends, object detection units around each corner, and anti-skew sensors on all tire bogies ensure that travel is aligned. Overload indicators monitor hoist current draw and notify operators when loads approach or exceed 100% capacity. The steel frame is reinforced with cross-bracing and torsion-resistant parts to endure wind, thermal expansion, and frequent transit across rugged terrain. Weatherproof electrical cabinets and sealed hydraulic components provide dependable performance in rain, dust, and salt spray situations.

The Result After Use

Stacking height increased from 6m to 10m. Yard space usage improved by over 18%. Pick-and-place cycles dropped below90s, accelerating throughput and improving on-time delivery.

Adaptability & Broader Applications

The 30-ton RTG crane combines powerful lifting capacity, off-rail maneuverability and precise control, and can be used in many other industries besides this one.

• Container terminals: The crane can stack and retrieve ISO containers as high as six levels, allowing for dense yard layouts without fixed rails. Its spreader attachment secures to each corner casting, and the diesel-electric motor offers power in remote dock regions.
• Airport & tunnel construction: On-site, the RTG handles precast concrete segments and modular tunnel liners. Its ability to go over compacted gravel pads and pivot in small areas allows crews to position big panels without the need for temporary cranes or railings.
• Steel processing yards: It raises and transports steel plates, pipe bundles, and coil sets through open yards. The RTG's anti-skew and anti-collision technologies ensure safe handling near furnaces, shears, and stacking racks, which require accurate load placement.
• Power plant maintenance: During turbine or boiler overhauls, the crane positions heavy machinery—rotor assemblies, pipe modules, and heat exchangers—on concrete aprons. Its variable-speed trolley motion properly aligns weights for installation, requiring no additional rigging.
• Prefabrication yards: In off-site construction assembly hubs, the RTG transports big modular components like wall panels, roof trusses, and mechanical skids between fabrication units. Fast cycle times and 360° maneuverability accelerate production and reduce on-site handling.

Why Choose Yuantai's 30T RTG Crane?

• Mobility: Yuantai's 30 t RTG crane requires no permanent rails, allowing for complete yard mobility. It can be driven on asphalt, concrete, or compacted gravel without any ground preparation. This rail-free layout enables you to quickly alter storage lanes as project requirements change.
• Robust engineering: The steel frame of Yuantai cranes is extremely strong. Cranes are designed with an anti-skew bogie, which ensures that all tires on the crane can always be aligned under load, preventing wear and tear due to deflection.
• Energy savings: Inverter drives on bridge and trolley motors reduce inrush current and smooth acceleration. The diesel-electric power unit operates at optimal RPM under fluctuating loads, resulting in increased fuel economy. Combined, these features save overall energy expenditures during heavy-duty cycles.
• Compliance & comfort: The operator cabin satisfies ergonomic criteria, including adjustable chairs, good sightlines, and HVAC controls. The complete crane is CE, TUV, and ATEX certified for safe operation in a variety of situations. This mix of comfort and compliance protects your workforce while also meeting global safety standards.
