This new roller offers a broad range of operating weights from 18,960 to 61,730 lb. (8,600 to 28,000 kg) and a higher maximum wheel load than former models of 7,715 lb. (3,500 kg) for deeper static compaction than previously achievable.
The Bomag BW 28 RH pneumatic tired roller features a large 106 cu. ft. (3 cu m) ballast compartment and efficient weight ballast changing system to boost wheel loads and improve compaction performance across a wide range of applications from city streets and county roads to interstate highways and airports. This new roller offers a broad range of operating weights from 18,960 to 61,730 lb. (8,600 to 28,000 kg) and a higher maximum wheel load than former models of 7,715 lb. (3,500 kg) for deeper static compaction than previously achievable.
The new flexible ballast system design of the BW 28 RH pneumatic roller features the option of adding concrete, steel and/or underfloor weights plus water, dry sand or wet sand to quickly adapt machine weight to the application, resulting in optimum compaction performance. With the ballast system, contractors can install four 1,653-lb. (750 kg) concrete weights, four 3,307-lb. (1,500 kg) steel weights or two 1,543-lb. (700 kg) underfloor weights in a matter of minutes. The ballast compartment accommodates up to 6,614 lb. (3,000 kg) of water, 9,920 lb. (4,500 kg) of dry sand or 13,228 lb. (6,000 kg) of wet sand to increase machine weight and wheel load.
Offering an 80.4-in. (204 cm) compaction width, the roller's eight offsetting tires overlap by 1.3 in. (3.3 cm) to ensure consistent, full-width coverage on each pass. The BW 28 RH roller's front axle boasts three-way pivoting to ensure even weight distribution across all tires, and the wheels' kneading and flexing action seals the asphalt surface for optimum quality. Helping to improve asphalt quality, the machine's asphalt temperature sensor lets the operator know that the roller is compacting the mat inside the correct temperature range. The optional tire inflation system varies tire pressure from 29 to 116 psi (2 to 8 bar), giving operators an efficient way to ensure the right contact pressure.
This roller's distinctive new front end design significantly improves visibility to the outside tires and the tops of the tires, allowing the operator to efficiently compact next to obstructions and detect debris pick-up. To reduce material pick-up and improve surface quality, the BW 28 RH roller features a pressurized water system with one fully adjustable spray nozzle per tire to ensure full-width coverage of each tire, according to the manufacturer.
Available scraper coco mats are spring-loaded and tiltable to help ensure uniform water distribution on each tire, while optional heat retention shields allow the tires to quickly heat up and maintain of high heat uniformity during operation.
The Bomag BW 28 RH pneumatic tired roller is powered by a 134-hp (100-kW) Deutz diesel engine that meets stringent Tier IV Final/Stage IV emissions standards. Featuring ecomode load-dependent operation that automatically matches engine output to the application, this pneumatic roller offers up to 30 percent fuel savings over previous models. The roller also runs quieter, boosting comfort for the operator and workers at the job site. The machine's one-piece, tilt-up hood offers unhindered access to all engine service points from ground level, reducing maintenance time.
Oversized steps leading up to the spacious platform allow the operator to quickly and safely enter the workstation. The pneumatic roller features a similar operator station design concept to that of all Bomag rollers, affording fast learning of machine control. An adjustable seat is fully rotatable along with the steering wheel and slides the full length of the platform, so operators can take advantage of 360-degree machine visibility. A new rocker brake pedal spans the full length of the platform to give operators safe access to braking function at all times. Bomag's field tested multi-function arm rest is connected to the movement of the joystick for comfortable operation, and the driver's seat, joystick and compact steering wheel are placed for the highest levels of operator comfort, according to the manufacturer.
For conducting on-board machine diagnostics, the roller's multi-function display at the operator's station provides a wide range of fault detection and service information, so issues occurring during machine operation can be quickly pinpointed and corrected. All machine service points are quickly reached from the ground to maximize machine uptime operation. The 52.8-gal (200 L) fuel and 89.9-gal (340 L) water tanks are conveniently located for fast filling, minimizing routine servicing time.
