Common Uses for Compactors
Compactors are typically powered by hydraulics and may range from small plate compactors that flatten soil or gravel in landscaping to large tractors with spiked steel wheels or bulldozer blades.
Types of Compactors
Jumping JackThe smallest of the compactors, Jumping Jack compactors tamper soil and other material that sits as the foundation under concrete slabs. These compactors are handheld, have small engines, and hydraulic rammers that push rammer shoes for compaction.
RollersThere are many uses for compactors with rollers, including landfill and soil compaction and asphalt grading. Roller compactors come with a water spray system to keep the drum and wheels wet. Types of rollers include:
Landfill CompactorLarge tractor compartment with spiked roller and bulldozer bucket
Pneumatic RollerNine to eleven oscillating rubber wheels for fine grading and soft materials.
Tandem Vibratory RollerSmooth front drum like a soil compactor and rear wheels like a pneumatic compactor. These come in different sizes, including large ones with large drums and two rear wheels and smaller versions with double rollers.
Soil CompactorDouble-spiked rollers support a cab and allow for heavy-duty compaction. On the front of the machine is a bulldozer bucket.
Manufacturers & ModelsWhen comparing manufacturers and models it is important to consider the following:
Type of Work
Determine size constraints, job type, and maneuvering needs before picking a compactor.
Variety of Material
The drums or vibrating plates on compactors perform differently depending on the material they are compacting. Jumping Jack compactors work best on sand, granular soils, and gravel and are ideal for backfill in trenches. Alternately, a sheepsfoot roller is best used on clay, cohesive soils, and silt.
Room to Move
Some areas such as trenches have confined spaces to work. Large drum tractors will not fit in the trenches, so Jumping Jack compactors are best. For large, open areas ride-on-rollers such as the pneumatic roller or tandem vibratory roller cover the expanse with quicker speeds and bigger equipment.
