MBW's new GP3000 vibratory plate has evolved into the GP3550. This model has the same low maintenance exciter unit of the previous model, but the company has updated the system to enhance travel speed. At 110 feet per minute, the GP3550 is approximately 20-percent faster than the previous model. Amplitude has also increased by 10 percent.

“The increased amplitude of MBW's exciter allows the vibratory plate to lift higher off the soil causing the plate to hit the soil harder in the downward motion,” says Tony Grinwald, project engineer for MBW. “This produces deeper compaction for every hit, compacting the soil faster with fewer passes. When higher amplitude is combined with increased travel speed, a much larger area can be compacted in less time, greatly improving productivity.”

The GP3550's operating weight decreases by 15 pounds, in spite of a heavier vibrating base assembly of stress-relieved, solid steel. A more efficient engine deck attributes to the weight reduction. The new deck features a full roll cage as standard equipment with provisions for an optional water tank for asphalt compaction. The new base plate is self-cleaning with an open-sided plate design that allows material to flow out and away from the belt/pulley assembly during operation.

MBW has also reduced hand/arm vibration on the new model by about 70 percent over the previous model. Models set up for soil compaction are prefixed GP while those set up for asphalt have the prefix AP.
