The joystick controllers used on the Skyjack SJIII Compact and Conventional scissor lifts, the SJ12/16 Mast lifts, and the Rough Terrain scissor lifts have incorporated a change to the enable circuit of the joystick. You may notice this change when you are troubleshooting the machine. Once the enable trigger is squeezed, an internal timer starts running; if a function is not operated within 7 seconds, the enable circuit is shut off and the joystick trigger must be released and depressed again to reset the enable circuit. The 7 second cut-out is used to inhibit tampering with or bypassing the enable switch with tape, a zip tie, or other means.

The Skyjack SJ12 and SJ16 model vertical mast lifts share many characteristics of the SJIII Compact and Conventional scissor lifts. One feature is the ability to remove the platform control box from the machine. This allows the operator to prevent unauthorized use of the machine or allows a technician to swap in a different control box if the control box becomes damaged or for troubleshooting. The connector contacts use a male and female pin and socket arrangement.

The Skyjack SJIII Compact and Conventional model electric scissor lifts with the MC option and all of the SJ12/SJ16 Vertical Mast models utilize a motor controller to control the function speeds.

The Skyjack Vertical Mast models SJ12 and SJ16 feature a traversing platform that allows the operator to extend the platform when elevated and safely reach a larger area without repositioning the machine. The platform can also be fully extended into the service position which provides a means of access to the hydraulic/electric compartment in the base to allow a technician to service the unit.

Skyjack electric scissor lifts (MC labeled units) and vertical mast units (SJ12 & SJ16) both use a Motor Controller to regulate the speed of functions. These Motor Controller equipped models use the same pump motor contactor as the models without a Motor Controller, but with one important difference: the Motor Controller units require a suppression, or flyback diode between the coil terminals on the contactor.
