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 crane machine typically straddle multiple lanes, with one lane reserved for container transfers.
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.
RTG Crane Design Features:
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.
