Rubber tyre gantry cranes

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

Liebherr rubber tyre gantry cranes demonstrate their technological advantage through increased productivity and a proven low cost per box move. The RTG has a rigid and stable steel structure allowing precise handling with smooth movements even at high speeds. The liebherr 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.

Power Options for Rubber Tyre Gantry Cranes

Fitted with an energy storage solution, this option offers substantial savings without any loss in productivity. Using stored power from the reserve when required, the reduced dependability on the diesel engine can deliver fuel savings of up to 30% dependent on operation.

A variable speed engine delivers optimum load dependant power levels by reducing engine speed in accordance with demand. Liebherr’s drive system ensures precise control over the entire process resulting in further savings in fuel consumption.

Liebherr RTGs are supplied with a dual speed diesel engine as standard. Controlled by the Liebherr designed drive system, the engine switches to idle mode when full power is not required reducing fuel consumption. Significant savings on fuel is achievable when compared with traditional RTG power options.

A full electric RTG is available from Liebherr, with many benefits. RTGs can be factory designed for electric operation or an E-RTG solution can be retro fitted. Power regeneration on the RTG to the grid also means that energy costs are further reduced. Options include a cable reeling drum or conductor bar system.

Electric RTGs can be fitted with a full diesel genset, auxiliary generator or connection for a portable generator to allow movement between the stacks.
