Operator Controls

The Steelbro SB121 Sidelifter has an analogue radio remote controller.

Older models of the SB121/122 Sidelifter have manual control valves. On these models in the event of an electrical breakdown the operating cycle can be completed manually by using these levers.

The control functions include:

• Two joystick controls which operate all crane arm and stabiliser leg operations
• A two position Legs/Arms switch to select stabiliser legs or crane arm control
• A positional rotary switch which selects the front or rear pair of cranes for 20' containers, or the frontmost and rearmost cranes as a pair for lifting 40' containers (the centre crane is folded flat with the deck of the trailer in this case)
• A red "mushroom" Emergency Stop button.
• Remote Start
• Horn
