GRD800, different to most of chain or belt driven rollers on the market, is with a fully hydraulic-drive system, consists of hydraulic pumps and motors not only on vibration but also movement, eliminating the need for regular periodic adjustments and changes while providing infinitely variable working speed.
Deadman control lever offers reversing protection.
Anti vibration controls ensure non-fatiguing and low vibration for the operator.
Drive system uses world famous brand SAUER variable pump, fixed displacement hydraulic motor, stepless speed, easy to change direction.
55 Liters, corrosion-free water tank mounted at the rear of roller reduces sound and keeps dust to a minimum.
Vibration is controlled by easy to reach on and off switch in speed controlled hand lever.
Two scraper bars on each drum ensure a clean drum when working on asphalt.
A fully hydraulic-drive system consists of hydraulic pumps and hydraulic motors provides infinitely variable working speed for travel and vibration, eliminating regular maintenance and adjustments that chain driven rollers require.
Fretures:
1.Central-gravity set lifting hook;
2.Deadman control provide safety protection;
3.Comfortable steering handle design;
4.Heavy duty vibration system provide vibration on both front and rear drum;
