Detailed Answer
Dual mode: the crane can be operated by remote or from the cab/floor pendant, with mode switching interlocked (only one effective at a time). The LDER LD series supports dual-mode wiring; XINGJIA likewise. Dual-mode value for warehouse cranes: remote as the main control + pendant as emergency backup (production continues if the remote fails).
