The GREAVES BW 151 ADH-2 Double Drum Vibratory Roller is a HEAVY DUTY Tandem vibrating roller designed for use on major contracts involving the compaction of wearing course, base course, roadbase and sub-base layers.
The BW 151 ADH-2 has an operating weight in excess of 8 tones and has proven compaction capability on medium to large-scale works.
The engine drives the pumps for the hydrostatic drive, vibration, and steering. Greaves rollers are fitted with the Rexroth Bosch / Poclain Hydraulic components renowned for its reliability and high performance.
The Hydraulic Motor on the Drum flange takes care of the vibration while the Radial Piston type motors fitted on the Drum ensures jerk free travel motion.
The Hydraulic system in Greaves Rollers follows the ‘Closed Loop’ principle, thereby increasing the Oil change period apart from utilizing lesser quantity of Hydraulic Oil.
A choice of high(50 Hz) and low (40 Hz) frequency settings permits optimum compaction on thin and thick layers apart from ensuring smooth surface finish.
The Auto-Vibration Cut off feature in the machines avoids damaging of the asphalt layer during reversal of direction.
The High KERB clearance of 925 mm enables the operator to use the machine close to medians & kerbs.
The Hydro-statically driven Water pump eliminates the troublesome electric DC motor driven water pumps in other Rollers. This water sprinkling system is supported by a Gravity feed system to avoid any stoppage due to water pump problem. The Timer in the system ensures optimum usage of the pump apart from avoiding water wastage.
OPERATOR FRIENDLY MACHINE
The factory set Auto- Vibration mode helps even un-skilled operators to run the machine at the optimum speeds to avoid “Rippling’ effect on the asphalt surface.
The ‘Sliding’ and ‘Swiveling’ seat combined with the ‘Tilting’ Steering makes the operation very comfortable even while doing edge compaction.
The Two operator’s Travel lever on either side of the seat along with emergency ‘Stop’ switch on a aesthetically designed Panel board, makes it the most operator friendly Tandem Roller.
Greaves Double Drum Vibratory Rollers also has its dimensions allowing it to be transported in “Tipper” Lorries from site to site.
Greaves Double Drum Vibratory Rollers, apart from being known as a high performance machine, is also renowned for its very low operating and maintenance costs.
The 6 Micron Hydraulic filter used extends the Oil change period to 2000 hours or One year of operation, whichever is earlier.
The direct drive for the travel motion through a Radial Piston type Hydraulic Motor on the drum flanges avoids the normally maintenance extensive Gear drive system incorporated in other Vibratory Rollers.
- The fully sealed and ‘Lubricated for Life’ Bearings for Travel & Vibration systems makes this machine a ‘Greasing Free’ machine. The Poly-eurethene Water tanks are rust-free and the machine runs on ‘Maintenance free Battery.
- The general maintenance for the machine is limited to checking for leakages and checking the Hydraulic and Engine Oil levels apart from carrying out the regular engine maintenance.
