Choose Right Machine For The Job

Getting the job done right when it comes to compaction requires knowledge of what it is being compacted before selecting the most suitable machine for the job.

Typically plate compactors and vertical rammers are used in a variety of applications.

Compaction Forces

Frequency and amplitude determine the type of force a compaction machine produces. Frequency is measured in vibrations per minute and measures the speed at which a machine jumps.

Amplitude is a measure of the maximum movement in one direction. In the case of a rammer it’s the distance the leg extends down.

Rammers are more suited to clay and silt-type soils where the lift (depth) is around 200mm or less. Forward plate compactors are more suited to gravel and sand-type soils where the lift is 300mm or less.

Rammers deliver a high impact force (high amplitude) making them an excellent choice for cohesive and semi-cohesive soils. The rammer is inclined at a forward angle to allow forward travel as the machine jumps. Plate compactors are low amplitude and high frequency, designed to compact granular soils and asphalt. The resulting vibrations cause forward motion and the heavier the plate, the more compaction force it generates.

The Hoppt compaction range includes vertical rammers, forward plate compactors and reversible plate compactors. The forward plate compactors include a 66kg narrow plate, 73kg solid plate, 86kg box plate and a 95kg solid plate while there are now five reversible models. Features vary from model to model including folding handles, lifting hooks and wheels. Hoppt vertical rammers include safety cut-out switches, lifting hooks and an engine protection frame. They are powered by a variety of HONDA petrol engines and HATZ diesel engines with all machines being covered by the Hoppt 24-month warranty.
