Industry's lowest maintenance reversible plates...mechanical shifting
The GPR 65, 68 & 77 Series are compact reversible plates ideal for narrow trenches and confined areas.
Heavy Duty Shifting
The heavy duty mechanical shifting mechanism allows for directional changes at constant speed. Endurance testing was terminated at 400,000 shifts without system failure - the best result MBW (and very likely any manufacturer) has ever achieved on a reversible plate shifting design.
The GPR65 and GPR68 are also high production plates. Travel speeds to 92 ft/min are achieved with good compaction conditions and the plates move with ease over irregular lift surfaces. Head-to-head competitive demonstration quickly establishes the comparative productivity benefits of the GPR65 and GPR68.
The GPR77 is a 400 pound reversible plate. The simple yet reliable shifting design lowers acquisition cost, is low maintenance and provides a geo-technical benefit in its ability to shift travel direction at constant speed. The GPR77 produces an amplitude of .095 inches, travels up to 85ft/min and handles all types of essentially granular soils.
