Detailed Answer
RTG (rubber-tyred gantry crane): requires remote walking + steering control, 12 keys + multi-speed; RMG (rail-mounted gantry crane): rail walking control, 12 keys + dual-speed. Both require: IP67+ salt spray, 200m communication, FHSS anti-interference, spreader interlock. Lideral LD-12DK fits; Xingjia port models are optional. RTG transfer operations cover long distances, so communication coverage must be planned.

Note:A safety attendant must be present to confirm during RTG remote walking.
