Hydraulic Reversibles

GPR78 hydraulic reversible vibratory plate GPR160 hydraulic shifting reversible vibratory plate

MBW's hydraulic shifting reversible plates solve maintenance problems that have long plagued this product type. MBW exciter systems are vented to prevent damage to shifting mechanism seals. Worn shifting seals are readily serviced from the outside of the exciter assembly (patented), eliminating the complicated process of opening and exposing the exciter assembly for service purposes. Maintenance is simplified, service time is reduced dramatically.

All MBW hydraulic reversibles are easy to maneuver, featuring forward and reverse travel as well as spot compaction. Powered by either Honda gas engines or Hatz diesels, these reversibles have plenty of power to tackle the toughest compaction applications.

MBW advises users to carefully consider which type of compactor best fits the job. If there is sufficient room to maneuver a single direction plate, productivity, cost and maintenance favor the single direction unit. But where maneuverability is key, reversible plates are the answer.
