A rubber-tyred gantry crane (RTG) or transtainer is a wheeled mobile gantry crane used to ground or stack inter-modal containers. Outbound containers are stored for future loading into boats, while inbound containers are stored for future collection by drayage trucks. RTGs often travel across multiple lanes, with one lane allocated for container transfers. Its mobility provides a rubber-tyred gantry crane with a wide appliance.

Main specifications of rubber tyred gantry cranes

• Capacity of rtg crane : 5 ton, 10 ton, 16 ton, 20 ton, 32 ton, 40.5ton, 50 ton
• Span of rtg crane: 18- 35 m

What is RTG crane? RTG crane is the short form of rubber tyred gantry crane which is a mobile gantry crane with rubber typred wheel used in intermodal operations to ground or stack containers. The rtg cranes are used to store the inbound containers for future pickup by drayage trucks, whereas the outbound containrs are stored by the rubber tyred gantry cranes for future loading onto vessels. RTG cranes typically straddle multiple lanes, with one lane reserved for container transfers.with the advantages of high mobiliety which enables a rubber tyred gantry crane with wide applications.

Rubber Tyred Gantry Cranes also called RTG cranes are used in particular for efficient stacking of standard containers, with similar funnction with the rail mounted gantry crane, whihc is a kind of container cranes.

According to different power supply, there are mainly two types of rubber tyred gantry crane,s the diesel engine-electric mode rtg cranes and diesel engine-hydraulic rtg cranes. Originally, RTG cranes were powered by diesel generator systems, however, , there has been a clear trend towards the electrification of RTGs in recent years for the shutting down diesel generators is not only good for environment,by reducing overall fuel consumption but also may be a growing economic argument for port operatorsbecause the electric motor is easy to use and needs simple maintenance.

Straddle Carrier Rubber Tyred Gantry Crane

A straddle carrier gantry crane, sometimes known as a straddle truck, is a freight-carrying vehicle that bears its load underneath by "straddling" it, rather than on top, as a typical truck does. The straddle carrier gantry crane has the benefit of being able to load and unload without the use of cranes or forklifts. The driver operates the lifting apparatus beneath the carrier without any outside aid and without leaving the driver's seat.

Straddle Carrier Rubber Tyred Gantry Crane

Straddle Carrier Rubber Tyred Gantry Crane

The straddle carrier gantry crane is a type of rubber tyre gantry crane lifting equipment with flexible and dynamic qualities and a lifting capacity of up to 1200 tons.

Applications of rubber tyred gantry cranes

What is the purpose of a rubber-tired gantry crane? Rubber tyred gantry cranes are most commonly employed at port terminals and intermodal yards for stacking and transferring ISO standard containers. The carrier straddles its load, picking it up and carrying it using a container spreader to attach to the top lifting points.

Some devices are capable of stacking containers up to four high. They travel at relatively moderate speeds (up to 30 km/h or 20 mph) while carrying a loaded container. The carrier's drivers sit sideways at the very top and face the middle, allowing them to view behind and in front of the vehicle. Straddle carrier gantry cranes have a lifting capacity of 60 t (59 long tons; 66 short tons), which is equivalent to two full containers.

• Bridge Projects -Handling rebar cages, lifting and storing of precast girders and casting plates, lifting and erection of precast bridge segment;
• Subway Tunnel -Remove the excavated residual soil, handling and transport concrete pipes, pipe fittings and heavy concrete aggregates, etc.
• Shipyard -Move, transfer, turnover ships from one place to another, help to maintenance, repair ships, etc.
• Jetty/Port, Manufacturing Factory, Storage Yard -Cargo/Goods handling, barge, etc, Lifting & handling heavy materials

Rubber Tyred Gantry Crane Parts & Components

• Metal Structure -The rubber gantry crane's main metal construction is made up of the main beam, legs, and bottom beam, among other things, and each component is joined by welding or flange connection.
• Main Beam -The main beam is the crane's primary force-bearing part which is fabricated in to a box shaped structure.
• The trolley track is supported by two major beams. There are two types of track laying: one in the center of the main girder section and one on a web on one side of the upper flange plate edge.
• Support Legs -The legs have a box-shaped variable cross-section structure in general. Because the inner side of the leg plane is normally flat, the area inside the leg is larger, which is advantageous for the architecture of the electrical and power rooms.To assure the size between the two main beams and boost lateral rigidity, the two legs are normally joined by connecting rods.
• Bottom Beam-The bottom beam is often a box-shaped construction of equal section that is connected to the crane operating mechanism by a pin shaft, and the connecting lug is a thick plate structure.
• Trolley Frame -The trolley frame is a combination I-beam construction with walkways on both sides and four-corner suspension platforms for maintenance of pulleys and other components.

Rubber Tyred Gantry Crane Safety Tips

Rubber-tyred gantry cranes must comply with safety technical operating regulations when operating.

Inspection Before Operation

• Examine the crane's walking path for obstructions and remove the anti-climbing mechanism.
• Perform all necessary engine pre-work inspections.
• Check to see if the main beam and crane running mechanism lights are working properly (only for night work).
• Check to see if the hanger connection signal and the spreader turn lock indicator light are working properly.
• Examine each limiter, emergency stop switch, and other safety device to ensure that it is in good working order.
• Examine the communication equipment and the alarm device to ensure that they are in good working order.
• Perform a no-load test to ensure that the mechanisms are normal.

Carry out a heavy-duty test run, which includes slowly lifting a heavy box by 0.3 meters and stopping to evaluate the lifting and braking performance; moving the trolley and checking the anti-sway system.

Matters Needing Attention in Operation

• The lifting height should be 0.3 meters higher than the height of the box.
• The crane must stay within the white line.
• Switch off all lights during the day and turn on floodlights at night.
• Overloading or lifting the load diagonally is not permitted.
• Spreaders and commodities should not be allowed to pass over people's heads.

Except in exceptional circumstances, it is not permitted to transport people or goods up and down the spreader or freight (such as equipment repair and maintenance).
