In some cases, the number of lamps that light up will decrease.※See graph 2■Extension Plate■Compaction Sensor "Compas II"810m2/hour1050m2/hour1360m2/hour■Extension PlateFor MVH-308, 408, 508 (75,150mm)※MVH-508 is equipped Extension Plate 75 mm as standard.+OptionCompaction Area/Hour①0.285m (A) x 12m /min. x 60min. /hour = 205.2m2 /hour②0.500m (A) x 27m /min. x 60min. /hour = 810m2 /hour①②MODELOperating WeightImpact ForceCentrifugal ForceWidthTravel SpeedTravel Distance/hourCompaction Area/hourkgkgfmmm (A)m/minm (B)m2 (A X B)MT-55H6210002650.26511660174.9MT-66HL7213002850.28513780222.3MT-77HRL7714002850.28512720205.2MVH-308DSY34146004450.445271620720.9MVH-408DSY40751005000.500271620810.0MVH-508DSZ52566006500.6502917401131.0[Remarks] The LED lamps of the compaction sensor do not show the absolute value of the soil rigidity. When using this machine always conduct tests such as the plate load test and dynamic load test (FWD) to determine the correct soil rigidity suitable for the work, and do calibration of the actual measured value and the LED illumination level.20
