TECHNICAL DESCRIPTION AND DATA
Section I. LAUNCHER VEHICLE
NOTE
When an item on the vehicle or launcher is referred to as front or rear, left or right, the cab
is taken as the front of the launcher vehicle, all references are taken as if personnel are
looking forward towards the cab. Therefore if the left hand side A-frame leg is being
discussed, the A-frame leg on the launcher vehicle's left hand side is the item being
described, i.e. the driver's side.
When referring to the launch beam the front of the beam is to be taken as the far bank and
the rear is taken as the home bank. Similarly the far bank carriage is the one nearest the
far bank and the home bank carriage is the one nearest the home bank.
Power Take Off (PTO) and Hydraulic Pump
2.1.1.1
The variable displacement pump provides the hydraulic power to operate the
equipment services. The pump powers the launcher and crane hydraulic circuits and
is driven itself via a power take-off on the vehicle transmission.
