Compaction Basics
The following features and benefits are standard on all Sakai vibratory soil and asphalt rollers:
Shock Isolation – Sakai's patented, custom-designed shock isolators reduce the transmission of vibration back to the operator and critical components.
Chassis – Super heavy-duty center hitch design provides superior chassis stability, ground contact and operator control.
Braking Systems – Sakai is the only roller manufacturer to offer three separate braking systems, including an automotive footbrake as a standard safety feature on all its machines.
- Dynamic hydrostatic braking is activated by simply returning the forward-reverse lever to its neutral position.
- The parking brake may be activated by depressing the brake switch at the operator’s station console. In emergency situations, this same braking system may be activated by depressing an automotive-style footbrake in front of the operator’s seat.
- A spring-applied, hydraulically-released (SAHR) brake is automatically activated upon engine or hydraulic system failure.
Safety – In addition to Sakai’s superior braking systems, ROPS and seatbelts are included as standard equipment on all rollers marketed in North America at no additional charge.
Engines – Sakai employs a selected range of highly popular diesel engines designed for a combination of power, fuel efficiency and long-term reliability. All engines comply with all current EPA/Carb emission regulations. Contractors rave about the fuel economy of these power plants.
Drive Train – Both contemporary and unique mechanical, hydraulic and electronic technologies are incorporated to transmit power effectively from the engine to the propulsion, vibration and steering systems.
Drums – The uniqueness of Sakai’s vibrating drum assemblies is the key to one of the most effective compaction tools on the market. Driven into rotation by state-of-the-art drive train components, Sakai’s unique eccentric weight system develops an extremely high force output per horsepower employed.

Propulsion – Typical propulsion systems in Sakai rollers employ a conventional, multi-speed, closed-loop hydrostatic transmission system consisting of a variable-speed piston pump and fixed piston motors. Unlike all other manufacturers, Sakai drives its drums directly rather than indirectly through the shock isolation system. This technique ensures efficient transmission of power while eliminating radial stresses on the isolators and resultant downtime obvious in competitive models. Combined with this positive transmission of power, the necessity of constantly replacing expensive shock isolators is virtually eliminated.
Product Support – Parts & Service is available through a team of well trained dealers across North America or via overnight dispatch out of the North American Headquarters in Georgia.
