Bomag

BOMAG   ROLLER

 We have 4 Bomag sizes available

  • 350mm
  • 650mm
  • 760mm
  • 900mm

Hand-guided double vibratory rollers are designed for general use on earthworks, granular or asphalt construction. Depending on model and specification, these machines have operating weights of approx. 600 to 1000 kg and are available in working widths of 600 mm to 750 mm. The low lateral projection, the proven double vibration system, the easy handling and low centre of gravity makes these models suitable for new construction work and maintenance of footpaths, road shoulders, cycle paths, parking areas and garage driveways, playgrounds, commercial and forestry roads.

These rollers feature large diameter drums with thick shells to provide maximum strength and durability. Travel and throttle levers are integrated into the adjustable steering handle to ensure easy handling. Their high compaction performance and compact design make these rollers ideal for a variety of light duty work.

Recommendations

  • THIS MACHINE USES DIESEL FUEL ONLY.
  • DO NOT LET MACHINE RUN OUT OF DIESEL (CALL OUT CHARGE TO RE-START R250.00).  
  • CHECK ENGINE OIL EVERY 2 HRS.
  • DO NOT JERK MACHINE FORWARD AND BACKWARDS TO TURN.
  • Bomag's do not operate in Water.        
  • Thickness of the layer to be compacted can be up to 200mm.
  • Always run engine at FULL SPEED when doing compaction work.
  • Avoid machine hitting against structures or rocks etc.
  • Never operate machine on solid/hard surfaces,eg concrete,aspalt.etc.when vibration is switched on.
  • Don't sit on machine while operating.
  • Stop machine before reversing or forward motion.
  • PLEASE NOTE ALL WATER PIPES WORKING CORRECTLY DAMAGE TO PIPES (R375.00)

This soil density chart shows properly compacted soil.Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure failure. Almost all types of building sites and construction projects utilize mechanical compaction techniques.

 

Why Compact?


There are five principle reasons to compact soil: - Increases load-bearing capacity
- Prevents soil settlement and frost damage
- Provides stability
- Reduces water seepage, swelling and contraction
- Reduces settling of soil


Static force is simply the deadweight of the machine, applying downward force on the soil surface, compressing the soil particles. The only way to change the effective compaction force is by adding or subtracting the weight of the machine. Static compaction is confined to upper soil layers and is limited to any appreciable depth. Kneading and pressure are two examples of static compaction.

Vibratory force uses a mechanism, usually engine-driven, to create a downward force in addition to the machine's static weight. The vibrating mechanism is usually a rotating eccentric weight or piston/spring combination (in rammers). The compactors deliver a rapid sequence of blows (impacts) to the surface, thereby affecting the top layers as well as deeper layers. Vibration moves through the material, setting particles in motion and moving them closer together for the highest density possible. Based on the materials being compacted, a certain amount of force must be used to overcome the cohesive nature of particular particles.
