eiengineering’s Compaction Wheels are designed to deliver optimal performance through quicker compaction – more particularly in trenches. They deliver exceptional compaction on the toughest terrains, under the harshest conditions, while lasting longer, using less fuel and minimising operational costs.
Compaction Wheels are designed to reinstate material to its original condition after remedial work has been carried out or pipes have been laid. Apart from different designs of wheels for various applications, there are some interesting designs of pads, some efficient, and some unfortunate. The ideal design are pads that are tapered from the flat surface to the back where they are welded to the wheel or roller so that they do not “lift” the compacted material as they roll over the surface.
The compaction wheel has three separate wheels with pads welded to the circumference of each wheel. These are held in place by a common axle and the excavator hanger brackets are fixed to bushed brackets between the wheels set to the axles. This means the compaction wheel is quite heavy and contributes to the compaction process which reduces the power needed from the excavator to compact the terrain, completing the job with less passes. Quicker compaction not only saves time, operator costs and stress on the machine, but also reduces fuel consumption and maintenance costs.
This type of compaction wheel is ideal for trenching applications as they enable the wheel to move and compact up to each side of the trench. Because they do not have a drum, they are more efficient than the compaction roller, as more material can be placed in the trench and continually rolled out achieving maximum penetration quite quickly.
Limitations of the Compaction Wheel
Compaction Wheels can clog quite easily in wet material, and wet clay can seize the wheel until it is either washed out, or dried and removed.
eiengineeirng fit “clay splitters” to our wheels to split the clay so that it peels off the wheel as it rotates.
The nature of the brackets over the axles in the compaction wheel means that a bushing system must be used to allow the axles to turn freely. However, steel bushes in compaction wheels have limited success in the past, often seizing or wearing prematurely due to a number of issues including, poor maintenance, bushes softer than the steel used in the axles, bushes of the same hardness as the steel used in the axles.
eiengineering have devised a specialised bushing system especially engineered to naturally lubricate the axles, and to also create greater wear resistance in our bushes to ensure our compaction wheels last for hundreds of miles of efficient and high-grade compaction.
Our Compaction Wheels are the most efficient and durable available.
The formula is quite simple: the heavier the compaction wheel, the greater the compaction and less load on the excavator. Light compaction wheels will not offer the compaction demanded by most authorities and require more passes.
Our Compaction Wheels are constructed from dense, eie80 grade high strength steel. They are as heavy as an anvil and employ better bushes and pad designs.
The design of the pads and the bushes used plays a very important role in increasing compaction performance. Our compaction wheel employs a tapered design, making compaction smoother and easier to compact the material.
Compared to knobby and square pads, tapered design makes it easier to lift it out of sticky materials like wet clay. Square or knobby pads do not compact as much as tapered pads because they displace the material when moved out of the ground.
