What is the RTG Crane?
A RTG crane (rubber tyred gantry crane) is a mobile gantry crane used in intermodal operations to ground or stack containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels. RTG cranes typically straddle multiple lanes, with one lane reserved for container transfers.

Rubber tyred container gantry cranes (RTG) are not only suitable for the front yard of the container terminal, but also suitable for the special container yard of the rear transfer station. It is suitable for the loading and unloading operations of ISO20’/40’ international standard containers (and heavy containers). The main technical features of the machine are: in the overall design, the lifting mechanism and the trolley operating mechanism are designed to share a set of driving devices, the mechanism is fixedly installed on the bottom beam, the trolley is equipped with a lifting pulley block, and the frequency conversion speed regulation method is adopted for the Correction during the operation of the cart. The machine has reasonable structure, convenient operation, and sensitive action. It is the first choice for loading and unloading machinery for container yard operations in port terminals. Today we share an RTG crane case from Singapore

Main points of RTG crane design
RTG Crane Parts:
RTG crane generally includes the following units: steel frame, hoisting mechanism, minimum slewing mechanism, and spreader anti-shaking mechanism, crane travel mechanism, turning mechanism, trolley traverse mechanism, container spreader, diesel generating sets, electrical equipment and other accessory equipment for safety.

RTG Crane Height:
Rubber tyre gantry cranes (RTGs) are available with spans of between five and nine containers wide (plus a truck lane) and with hoisting heights from 1 over 3 to 1 over 6 containers high. Supplied with eight rope reeving anti-sway system and drive systems, the RTG delivers exceptional productivity and reliability in container stacking.

The RTG has a rigid and stable steel structure allowing precise handling with smooth movements even at high speeds. High quality standard achieved, with ease of maintenance results in minimum downtime, increasing throughput per RTG unit. Precise control using simultaneous drive motion removes the need for a headblock or side shift. Available in either eight or 16 wheel configuration with numerous productivity options from DGPS and auto steering to stack profiling and automation.
