AP2782 - Group 4

BC = Bogie Centres. GC = Ground Clearance. MPG = Miles per gallon. TC = Turning Circle. WB = Wheelbase.

RAF (Stores) Ref Nos were not given in this document but where they are shown, they have been assumed from later versions of AP2782. This edition also did not include photos so these have been added from AP2782A. When a vehicle appears in more than one edition of AP2782, the technical details have been assembled from all available data.

Details shown in RED are not quoted in the relevant entry and they are assumed to being the same as those shown for the basic vehicle given under other Groups.

Power supply for the beacon is provided by a 4 kVA 230V, single phase, 50 c/s, alternator driven by a Coventry-Climax Type E or ZE petrol engine or a Ford 10 hp petrol engine and a control panel. A 4 kVA transformer, adjustable to suit supplies to range from 190-230V, permits the alternative use of an external source of power supply. The neon tubes are individually supplied by eight transformers which are housed in a compartment forward of the generator and a smaller compartment houses the flasher unit. A 12V lighting set is incorporated for servicing purpose. The capacity of the generating set fuel tank is 23 gallons.
