Locatelli Gril 87.80 - Rough-terrain cranes
Box section frame with internal ribs fabricated from high-strength steel.
Four hydraulic outriggers moved by horizontal cylinders and jacks with hold valves. Excursion of the beams in three positions: 0%, 50% and 100%. Easily removable floats. Controls and bull’s eye spirit level placed in the cabin.
Diesel, turbo intercooler, electronically controlled and water cooling. Dry type air cleaner with safety cartridge and clogging indicator.
Torque converter with Powershift gearbox with six forward gears and six reverse gears.
Gear type, driven from power-take-offs mounted on torque converter.
Front: drive/steer axle with differential and hubs with planetary reduction, rigidly mounted on the carrier frame. Rear: drive/steer axle with differential and hubs with planetary reduction, pivot for off-road use or locked in a horizontal position for the use on tyres.
