Description
this is a "cutaway" view of the basic diesel-powered model
Derived from the diesel-powered JCB 525-4 telescopic handler -- JCB pioneered the telehandler concept in 1977; the 525-4 is from about 1981. About 370 kg of fuel tank, engine and transmission parts were removed; they were replaced with a Mk 1 fusion generator and a 40 kilowatt electric motor. The radiator was retained for high-power operation (i.e., powering other equipment), however the forklift can usually operate without requiring the cooling system.
It has all-wheel drive and rear-wheel steering. There is a towing eye at the rear, mostly for towing this vehicle, but it can tow military or contractors' trailers -- however, there's not connection for brake lines.
The cab is fully-enclosed by a roll-over cage, with polycarbonate windows all around. It's got a heater, windshield wiper.
The lift height with the full rated load is 6.4 meters; the reach is 3.65 meters; the maximum load at full reach is 860 kg.

Maintenance and Installed Equipment
Since the internal combustion engine has been entirely replaced, keeping the vehicle operating is much easier -- but it still needs maintenance. Besides daily checks, an actual inspection is called for by the manual after 100 hours, and a more thorough inspection every 400 hours.
-
Cooling: 19.3 liters of water is needed to fill the radiator and cooling system.
-
Lubrication: the differentials and wheel hubs need a total of 23.5 liters of lubricating oil. The chassis and crane need some lubricating and greasing every so often.
-
Hydraulics: 275 liters of hydraulic fluid are needed, for the brakes and boom.
-
Tires: the tires are 12.5x18 and 15.5x24
Accessories
There are several options and accessories: an extension jib and crane hook (giving a maximum lift height of 7.9 meters); a simple steel dump bucket (for rubble or gravel handling, not really able to cut into dirt very well); a 2.4 meter wide aerial work basket ("personnel platform"); and various fork and mast variations (including a lifting mast). With a lifting mast at the end of the boom, maximum capacity is reduced to 1500 kg, but of course the operator has more flexibility in placing and raising the load.
A military tow pintle is fitted at the rear, along with power and brake line cables.
Variants
The Project tested the vehicle with an array of 100 "vehicle batteries" instead of the fusion generator and radiator ... it could operate at continuous full power for 3.75 hours, or in a more typical 60% "use factor" for 6.25 hours.
