The primary (Upper) control box is permanently fitted to the front of the platform. It
features a multi-use joystick which provides proportional control for all the machines
functions. That includes, raising or lowering the mast, raising or lowering the jib,
rotating the mast assembly, and also to drive and steer the machine.
A safety Interlock Switch or ‘deadman button’ is incorporated into the Joystick. It must
be activated at all times in order to operate any function. This feature allows for one-
handed operation.
The secondary (Lower) control box is fitted to the mast cover at arm level. It features
an enable button and selector buttons to provide pre-programmed speeds for all
functions except drive and steering. This control station is used primarily for service-
type operations including pre-operation inspection. It should
never be used to position
a manned or un-maned platform.
NOTE: It may be used in the event of emergency to lower the manned platform.
