Product Description
Transmitters
F21-4S-TX: Equipped with 4 single-speed control buttons plus a start and emergency stop button.
F21-4D-TX: This wireless crane hoist remote control double speed transmitter features 4 double-speed control buttons, one start, and one emergency stop button. The wireless crane hoist remote control double speed F21-4D-TX is optimized for equipment requiring multi-speed adjustment.
The corner bumpers design of transmitter protects the remote control, making it less prone to damage and drop-resistant. When used with a safety lanyard, it provides double protection. It adopts an "emergency stop mushroom head," and the stop response time of the emergency stop is shorter compared to that of similar products.
