‘Speedcrafts’ 3-wheeled Diesel Road Roller, Model DRR/10 (4 speed) & Model DRR-3/10 (3 speed), capacity 8/10 tonnes.
Fabricated out of mild structural steel and all joints checked and tested to performance. Easy accessibility to all parts for overhaul and inspection is given utmost importance in design of these Diesel Road Rollers.
Powered by Simpson S-4(I) water cooled Diesel Engine with 12 volt electric starting system and an alternative hand start arrangement.
The Clutch, Gearbox and Differential are integrated in a single unit. The clutch is of the heavy automotive double acting type, controlled by a single hand lever. A forward or backward movement of the lever gives a smooth and instantaneous corresponding direction of travel to the roller in any gear setting.
