Volvo launches PT220 pneumatic tyre roller in Middle East and Africa

New model features a fuel-efficient and powerful Volvo diesel engine, increased performance characteristics and enhanced safety features

Volvo Construction Equipment has introduced a new pneumatic tyre roller in the Middle East and Africa market, which is more powerful and fuel efficient as well as quieter in operation.

Volvo CE announced that the new PT220 roller features a Volvo D5 Tier-3 compliant turbo-charged diesel engine and incorporates safety features such as Roll Over Protective Structure (ROPS) sunshade, reversing alarm and automatic engine shutdown.

The announcement added that the PT220 compacts using the forces of mass and manipulation and can be adapted to a variety of applications by adding or removing ballast or by adjusting tyre inflation pressure. The positioning of the tyres, four each on front and rear, helps to ensure uniform surface coverage while rolling.

Volvo added that the tyres’ kneading action against the material surface provides excellent compaction and an isostatic suspension for the front tyres helps to keep the roller stable on irregular surfaces as well as maintain uniform tyre contract pressure.

Other highlights of the PT220 include dual seats with a sliding console to give the operator the most convenient work position and the best view of the work area. In addition to equal forward and reverse speeds, the hydrostatic drive also features a high-speed travel mode that allows operators to get to the worksite quickly. For increased compaction versatility, the maximum weight of the machine can be increased using a number of ballast options, including water.

The PT220 is powered by a turbocharged four-cylinder Tier 3/Stage IIIA engine with an output of 135hp. Volvo says it is fuel efficient and exceeds the requirements of exhaust emission legislation across the machine’s intended market. Propulsion comes in the form of a closed loop hydrostatic parallel circuit, which is fitted with two heavy duty radial piston motors.

Travel speeds range from 0-15km/h. Forward to reverse directional changes are smooth, using a simple control lever to reduce operator fatigue. To maximize effort and minimise service requirements, the transmission delivers power directly to the rear wheel motors.

The PT220’s has a pressurised water system for consistent water flow control from the rust-proof water storage tank. The operator can precisely adjust water flow to the tyres, to prevent then picking up asphalt material. Water usage is also minimised, extending the periods between refills. For improved safety, thanks to an operator-presence switch incorporated into each seat, the PT220 will also shut down its engine and apply the brakes if the operator removes himself from the seat.

For easy maintenance, the engine and hydraulic components are easily accessible, thanks to a swing- up engine hood and access step. Daily checks on engine, battery, radiator, filters etc. can be done from ground level. A lockable vandal cover protects the operator console, while lockable engine hood, fuel cap, water fill cap and deck access doors help deter theft and vandalism. Water nozzles and screens can be quickly removed, cleaned or replaced. The water spray system is rust proof, with rubber distribution lines and brass spray nozzles.
