Following the design concepts used on the BF 300 and BF 600 series finishers the newly developed BF 800 model, with an operating weight of 20 t and maximum screed width up to 10 m, complements perfectly the range of BOMAG finishers
Like all BOMAG machines this unit was tested under extreme working conditions on job sites around the world before coming into series production.
With paving widths of 2.50 m to 10 m, the BF 800 is designed for medium to large-scale construction projects on motorways and major roads. This BOMAG finisher can be used where ever high paving outputs are needed, for example on larger road works, local road networks and in inner city areas. With a compact design, this finisher is truly multi-talented – and boasts an impressive performance to match.
Available as a manoeuvrable wheeled model or high-traction tracked unit, the BOMAG BF 800 finisher has massive power reserves with a 139 kW (189 PS) 6-cylinder Deutz engine featuring low noise and exhaust emissions. The ECOMODE machine management system provides intelligent use of energy, reduced fuel consumption and lower environmental pollution.
The screed – at the heart of the paver
The screeds feature electric heating as standard; the heating elements are cast in an aluminium block making them highly robust and durable. With optimised heat transfer, heat is evenly distributed throughout the screed plates and fast heat-up times are guaranteed. Also, only 1,000 rpm (idling) is required in the warm-up phase for paving widths of 6.0 m and just 1,400 rpm (ECOMODE) for widths over 6.0 m.
For the maximum screed extension of 10 m mechanical attachments are used, fitted without complicated braces with quick fit sliding couplings, and guarantee the quickest set up times with minimum site labour.
BOMAG screeds give paving thicknesses up to 30 cm and crown adjustments of -2.5% to +4.5%. Generous smoothing plate depths of 40 cm and the overall 4,200 kg weight of the S 600 E basic screed (S 500 E = 3,900 kg) give high level pre-compaction and perfect surface finish with the tamper and vibration units.
From prototype to serial production
Before serial production of any machine BOMAG prototypes are tested on construction sites across the world and the BOMAG BF 800 finisher was no exception. Subjected to extreme temperatures up to 50 °C, laying gravel materials on dusty slopes, 24-hour operation on asphalt with very tight time frames, and paving 10 m mats on motorways. No difficult and demanding job is overlooked to ensure that series production machines meet all demands with total reliability and paving quality.
