Check out our latest 30t rubber-tyred gantry crane delivered to Singapore! Perfect for your material yard needs, it boosts efficiency and productivity.
Our client is a large yard operator adjacent to a container terminal. They provide services to civil engineering contractors, petrochemical maintenance teams and modular construction companies. The yard handles more than millions of tons of various types of cargo every year, with peak daily throughputs of thousands of tons. Customers tell us that their yards serve the construction, oil and gas, and power generation industries. They primarily store and run heavy loads such as steel coils, precast concrete pipe sections, piping assemblies and transformers. They needed a reliable, flexible crane that could operate in the yard to move materials.
Customer's Usage Requirements
This project involved a 30-ton rubber-tyred gantry crane delivered to Singapore for use in a busy material yard. The customer needed equipment that could handle heavy loads every day while keeping operations smooth, safe, and cost-efficient. In a yard environment, space is limited and delivery deadlines are tight. The crane had to perform reliably under constant use.
1. Load Capacity
The crane needed to lift up to 30 tonnes at different outreach distances. This means it had to maintain stable performance not only when lifting directly beneath the spreader, but also when handling loads positioned further away. In real yard operations, materials are not always perfectly centered. A strong structure, reliable hoisting system, and precise load control ensure safe lifting even at extended outreach.
2. Flexible Access
The material yard already had established stacking lanes. The crane had to move smoothly along these parallel lanes without requiring ground regrading or structural changes. This flexibility reduces installation costs and shortens project timelines. A rubber-tyred design allows the crane to travel independently, making it easier to adapt to changing yard layouts.
3. Safety Controls
Safety was a top priority. The crane needed obstacle detection systems and real-time load monitoring to prevent accidents. In a busy yard, people, vehicles, and cargo move at the same time. Advanced sensors and monitoring systems reduce collision risks and prevent overloading. This protects both the customer's workforce and equipment. Strong safety features also lower downtime caused by incidents and support long-term operational stability.
4. Energy Efficiency
The customer wanted to reduce power consumption and lower carbon emissions. Modern drive systems, optimized motor control, and energy-saving technologies help cut electricity use during lifting and travel. Lower energy use means lower operating costs over time. If sustainability is important for your company, choosing an energy-efficient crane can also support environmental goals and compliance requirements.
5. Maintenance Support
To ensure long-term reliability, the crane was equipped with remote diagnostics and predictive maintenance alerts. These systems monitor performance data and notify the service team before small issues turn into major problems. This reduces unexpected downtime and helps plan maintenance more effectively.
Pre-Implementation Challenges
Before installing the RTG crane, the yard's material handling faced three major obstacles that limited productivity, increased costs, and raised safety concerns.
1. Limited Stacking Height
Relying on forklifts capped at a 6 m lift height restricted the yard to five-tier stacking. This low stack density expanded the yard's footprint by 18 %, driving up land rental expenses. Operations also suffered from constant reshuffling as material piles ran out of vertical space, further slowing down loading and unloading cycles.
2. Equipment Bottlenecks
When the load exceeded the capacity of the forklift, the crew had to bring in a mobile crane. Each lift required setup, repositioning and troubleshooting, taking an average of five minutes per move. These extra hours add up and may even lead to longer delivery lead times, which can cost them money once it leads to longer cycle times.
3. Safety and Stability Issues
Forklifts struggled with multi-tonne bundles on uneven ground, especially during monsoon season. Ruts and soft patches caused tipping incidents, leading to unscheduled maintenance and minor operator injuries. These risks forced work stoppages and added pressure on safety teams to manage unstable conditions.
Product Design and Features
A 30-ton rubber-tired gantry crane is a mobile crane used in storage yards, fabrication shops, and construction sites. It lifts heavy loads like steel structures and shipping containers and provides enhanced mobility on uneven surfaces due to its rubber tires.
1. Design Structure
The main girder of the 30-ton rubber-tired gantry crane is fabricated from robust, box-shaped steel profiles and engineered to safely support a 30-ton rated lifting capacity. Depending on the requirements of a facility, its span can vary from around 10 meters up to 35 meters, providing the reach needed for different layouts. To ensure reliable operation—even in harsh outdoor conditions—the girder is designed not only to bear vertical loads but also to resist torsional stresses and wind pressure, maintaining structural integrity and precise load handling under all expected forces.
2. Mobility and Drive Systems
The rubber-tyred undercarriage of a 30-ton gantry crane rides on high-load pneumatic or solid rubber tires, typically arranged as eight or sixteen wheels split between two bogies. Each bogie features its own hydraulic steering or independent drive system, allowing the crane to maneuver smoothly and even pivot within tight yard spaces. This configuration combines load-bearing capacity with exceptional mobility, making the crane ideal for operations where rail-mounted systems aren't practical.
3. Traveling Mechanism
The traveling mechanism of a 30-ton rubber-tired gantry crane is driven by high-torque electric motors or, in remote applications, by onboard diesel generators. It propels the crane at speeds up to 20 m/min while relying on travel limit switches, anti-skew sensors, and anti-collision devices to maintain precise alignment and ensure safe operation. Engineered for both straight-line runs and curved-path movements, this system combines reliable power with advanced electronic safeguards to navigate complex yard layouts without compromising speed or safety.
4. Electrical System
The electrical system of a 30-ton rubber-tired gantry crane can be tailored to site requirements via diesel-electric, pure electric, or hybrid power configurations. Operators control crane functions from a cabin, with a pendant station, or even wirelessly, all of which interface seamlessly with an onboard PLC for advanced automation, diagnostics, and performance monitoring. Built-in safety features—including emergency-stop circuits, overload protection relays, and ground-fault detectors—ensure that power delivery and control commands remain reliable under all operating conditions.
Key Features and Functional Capabilities
The 30-ton RTG crane delivers heavy-duty lifting and flexible movement in outdoor yards. Its design combines robust load handling with off-road mobility and precise steering. Below are its core capabilities:
1. Load Handling
This crane lifts up to 30 ton loads with ease. It moves steel plates, stacked pipes, precast concrete elements, and large machinery across open yards. Custom spreader beams or lifting clamps attach quickly to handle irregular or bulky shapes. With its heavy-duty hoist and spreader bar, the RTG ensures stable, secure lifts every cycle.
2. Terrain Adaptability
Fitted with large rubber tires, the crane travels smoothly on asphalt, concrete, or compacted gravel. It maintains traction on uneven or sloped surfaces, where rail-mounted gantries would struggle. Without the need for fixed tracks or embedded rails, site preparation costs stay low and deployment times shrink.
3. Maneuverability
The RTG's four-wheel steering offers a full 360° turning radius. This tight maneuvering fits into congested yards and narrow access points. Operators can tow the crane between locations or drive it under its own power. Quick relocation keeps projects moving without relying on external transport equipment.
Configuration Options
You can tailor the RTG crane to your site's lifting and space requirements. Below are the main configuration choices:
1. Single-Girder or Double-Girder Designs
Choose a single-girder layout for lighter duties and lower cost. It uses one main beam and is easier to transport and set up. Opt for a double-girder model when you need extra rigidity, higher lift heights, and dual-hoist capability. The twin beams spread the load more evenly and support larger spans with less deflection.
2. Optional Attachments
Optional attachments allow the customer to customize the crane to match different material handling needs and improve overall efficiency. You can install spreader bars to keep long or flexible loads, such as pipes and steel beams, stable and level during lifting and transport. Lifting magnets are ideal for handling steel plates and scrap quickly without the need for slings, which saves time and labor. For bulk materials like sand, gravel, or scrap metal, hydraulic clamshell or orange-peel grabs provide fast and controlled loading and unloading. Each attachment connects to the crane’s spreader interface, so you can switch tools within minutes and adapt easily to changing job requirements. This flexibility helps increase productivity, reduce manual work, and ensure safer lifting operations in your facility.
