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

Equip the crane with specialized lifting tools to match your material types:

• Spreader Bars: Keep long or flexible loads, like pipes or beams, level during transport.
• Lifting Magnets: Pick up steel plates and scrap quickly without slings.
• Grabs: Handle bulk materials—such as sand, gravel, or scrap—using hydraulic clamshell or orange-peel grabs.
• Slings: Use wire rope or synthetic slings for irregular shapes and bundles.

Each attachment mounts to the crane’s spreader interface, letting you switch tools in minutes and adapt to changing cargo.

Product Advantages

The 30-ton RTG crane delivers gains in productivity, uptime, safety, and operating costs. Here’s how it adds value on the yard:

1. Enhanced Productivity

By stacking containers and materials more tightly, the crane increases storage capacity and cuts land rental expenses. Its fast hoist and trolley cycles speed up load transfers and shorten project timelines. With radio remote controls, a single operator can oversee multiple cranes or yard tasks, reducing manpower needs while keeping operations fluid.

2. Reliability and Uptime

Integrated predictive-maintenance alerts warn you of bearing wear or hydraulic issues before they cause breakdowns. This feature can lower unplanned outages by up to 40 %. The crane’s heavy-gauge steel frame resists fatigue, and soft-start drives reduce mechanical shock, extending the life of motors and gearboxes. Standardized spare parts mean you can stock fewer SKUs and replace components quickly when service is required.

3. Safety and Compliance

Built-in obstacle detection and digital load-indicator systems comply with ISO 13849 (machine safety) and EN 15011 (crane safety) standards. The rubber-tyred chassis maintains stable travel on uneven or sloped surfaces, reducing the risk of tip-overs. The operator cabin meets ISO 6055 guidelines for visibility and ergonomics, ensuring clear sightlines and a comfortable working environment.

4. Cost Efficiency

Variable-frequency drives on the hoist and trolley motors cut energy use by up to 18 % per lift cycle, lowering electricity bills. Because one operator can handle more tasks remotely, labor costs drop by around 12 %. The crane’s durable rubber tires wear more slowly than standard industrial wheels, extending replacement intervals by about 30 % and further trimming maintenance expenses.

Additional Applications

The 30-ton RTG crane’s combination of heavy-lift capacity and off-road mobility makes it a versatile asset across various material-handling sites. Below are several sectors where its unique capabilities deliver clear benefits.

1. Container Terminal Operations

In mid-sized ports or regional depots lacking room for full-size rail-mounted gantries, the RTG crane stacks ISO containers up to 30 t. It transfers loaded units between yard blocks and truck or chassis, streamlining gate moves and avoiding costly rail infrastructure.

2. Intermodal Yards

With adaptable spreader bars, the crane handles ISO containers, swap bodies, or rail-wagon modules. It cross-docks freight from rail cars to trailers within the same yard, reducing double handling and speeding up turnaround for multi-modal shipments.

3. Steel and Metal Processing

The crane lifts and moves steel coils, ingots, and plate bundles in coil yards or near melting shops. Its precise load-weighing system ensures each pick meets weight requirements, while the stable hoisting action protects edges and prevents coil deformation.

4. Power Generation Maintenance

During planned outages at power plants, the RTG crane stages 30 t transformers, turbine rotors, and piping modules on concrete aprons. Its mobility lets crews position heavy components close to the work site without building temporary tracks or supports.

5. Prefabrication Yards

In off-site construction hubs, the crane handles large precast panels, beams, and modular sections with care. Variable spans and turnkey spreaders allow gentle load handling. This flexibility supports quick layout changes and high-volume production of building elements.
