Gantry cranes are overhead cranes that have a hoist, trolly, and bridge. They are mostly utilized for exterior yard handling operations for goods, cargo, and bulk cargo. Typically, gantry cranes have attributes like great space utilization, a wide operating range, broad adaptability, and strong commonality, among others. In this post, we’re going to be looking at a special kind of gantry crane called a rubber tires gantry crane.
What Is A Rubber Tyred Gantry Crane?
This is a wheeled mobile gantry crane with rubber tyres, also known as an RTG crane or transtainer. It is used to ground or stack intermodal containers. The spans of rubber tyre gantry cranes (RTGs)(gruas rtg) range from five to nine containers wide (including a truck lane), and the hoisting heights range from one over three to one over six containers.
Well-designed rubber tyred gantry cranes have rope reeving anti-sway systems and driving systems to offer great productivity and dependability when stacking containers. RTGs typically handle inbound containers for vessel loading and outbound containers for future collection. They mostly have more than one lane, whereby one of these lanes is always left aside for container transfers.
Operation Mechanism of Diesel-Powered Rubber Tyred Gantry Crane
They are powered by diesel generator systems of 100 to 600 kW, requiring a horsepower of about 134 to 805 hp. Being diesel-powered (because of their mobile nature), they lack an electrical grid to transfer energy when lowering containers(grua portico sobre rieles). As such, they normally have huge resistor packs to quickly dissipate the energy of lowering or decelerating containers.
What’s more, because each diesel-powered RTG consumes up to 10 US gallons of gasoline per hour (8.3 imp gal/h; 38 L/h), they are notorious port pollutants. When buying one, therefore, you need to think of ways to counterattack the effect of greenhouse gases released into the air.
A New Dawn: Electrical Rubber Tyred Gantry Crane
In response to the pollution issue, manufacturer’s started making electric rubber-tired gantry cranes. Notable players include The She Kou Container Terminal(grua portico contenedores). It debuted the first electrical rubber-tyred gantry cranes (ERTG) in China in August 2008.
Applications of RTGs
Rubber tyred gantry cranes are widely employed in the intermodal transportation industry and other industrial sectors. Applications include:
• Positioning pipelines
• Erecting sizable imbalanced structures
• Assembling sizable manufacturing components.
Features of Rubber Tyred Gantry Crane
• RTG’s steel structure is robust and stable, enabling precise handling and fluid movements even at high speeds.
• Simple maintenance so downtime is kept to a minimum, enhancing throughput per RTG unit.
• Available in either an eight or sixteen-wheel configuration with a wide range of productivity features, including stack profiling, automation, and DGPS.
• Unique rope reeving anti-sway system from Liebherr
• Direct-drive transportation systems
• Each corner has one gantry drive
• Gantry steering alignment
