Vibration System

  • Pod-style eccentric design
  • Dual amplitude and frequency with world class piston pump and motor


Hydraulic System

  • Improves efficiency by 20% vs. open center system
  • Reduces oil contamination, extends life of hydraulic system
  • Maintains higher system pressure with less energy loss
  • Allows for simpler hose routings
  • Requires smaller volume hydraulic tank, reduces maintenance cost

Cooling System

  • Modular cooling package design
  • Up to 49°C ambient temperature cooling capacity

Key Application

SEM510 and SEM512 SCOM are widely used in road work, sub-base, parking lots, site development, water and sewer trench work, hills and uneven terrain

Cab & Operation System

  • Canopy standard, Cabin + A/C optional
  • Big room, superior front, side and rear visibility
  • SEM512/510 is hydrostatic compactor. The operation system is very simple, it just has two control levers, one for throttle control, another one is for forward/backward and brake control
  • A/C with interior cycle/out side fresh air cycle selection for better defog capability
  • Safety belt is standard
