Working Process

RTG container crane (Rubber Tyred Gantry crane) is a core mobile device in port yards for contacontrol, achieving continuous and stable container operations in ports and yards.iner stacking, handling, and cross-area transfer. Its workflow revolves around dispatch instructions, precise positioning, and safe lifting.

Operation Instruction Reception and Inspection
After receiving system instructions, confirm the target operation location and complete equipment inspection, including tires, brakes, steering, communication, and safety environment checks, ensuring operational conditions meet requirements.

Gantry Travel and Positioning
Move the gantry using drive wheels, supporting 90° turning and “crab walking” mode for fast repositioning; with laser/GPS correction and synchronous control, achieve precise zone-level positioning.

Trolley and Spreader Fine Positioning
The trolley moves along the main beam to the target above, the spreader automatically adapts to 20ft/40ft specifications, and the positioning system completes precise four-corner alignment.

Lifting Operation
After the spreader locks the container corner fittings, the hoist starts to lift smoothly to a safe height, with speed control to minimize sway.

Transfer Positioning
The container moves with the trolley to the target area above, for either truck handling or yard stacking, with precise position adjustment completed again.

Lowering Operation
The container is gently lowered to the target position, the twist locks are released, and the spreader disengages, completing a single handling or stacking operation.

Operation Completion
The equipment returns to standby position, anchors are engaged if necessary, and the operation completion status is reported to the dispatch system, waiting for the next instruction.

The entire RTG container crane workflow focuses on precise positioning, efficient transfer, and safe

Parts
