BOMAG is offering new soil compacting solutions for the 4-8tonne class with the BW177D-5 being the first of this improved range. Weighing in at 6.7tonnes, the machine has a 55.4kW diesel and Friedrich Knoche, a product manager for the soil compactors said, “These machines are totally new and they have Tier 4 Final engines. There are two versions, the DH with better gradeability and the D, which is the standard model.”
Efficiency and performance are said to be improved over previous generation machines and Knoche said, “All the machines are equipped with the Ecomode, while the DH version comes with a double pump. It has one pump at the front and one at the back so you always have full power for gradeability.”
He explained that the machines are also more compact, which makes them easier to transport and this is further aided by a loading function that can be set by the operator, slowing the drive system and providing high torque for when the compactor needs to be driven onto a truck or low loader. The machine is designed for use in sites with restricted space such as urban applications and Knoche said, “It has a small turning radius, low emissions and it’s very quiet.”
The operating platform has been improved and the machine has an adjustable steering wheel, the firm’s sophisticated Terrameter compaction measurement system. “It’s integrated with the display in the middle. It gives the driver an idea of the compaction. You can see where the weak spots are and what needs more compaction,” Knoche said. The Terrameter system is integrated with a GPS package so as to give location data, which can all be recorded for later analysis of operations.
Maintenance has been improved, with better access for servicing.
