As an important part of road machinery, GRH provides a large number of gear-type vibration motors , gear pumps, ?and manifold control valve for road rollers. We can offer the solutions to the hydraulic system of the small compactors. ??According to the vibration requirement, the displacement of the gear motor can be specially made to meet the consistent vibration speed when the double barrel is vibrated. High-efficiency gear pumps and high-quality matching control valves ensure the stability and durability of the roller during operation.
