Vibro Hammer
Vibratory Hammer Glossary - BRUCE prepared this glossary to standardize the technical terms and expressions that construction contractors use when operating BRUCE hydraulic vibro hammers, vibratory hammers, and pile hammers on job sites worldwide. We wish and aim that this will be standard in the pile driving industries.

It is the width of periodic vibration measured in the Vibro Hammer, Vibratory Hammer.
The Amplitude is a key factors for Vibro Hammer, Vibratory Hammer to be selected and it must be higher than sand and also it should be between 3~6mm for clay soil.
General description of Amplitude is that it should be between 6~12mm. The Amplitude will travel vertically to shear the soil away per vibration when drives sheet pile or casing pile and other piles.

It is consisting of three main parts of a shell, a Bladder and a oil port and is placed inside the Power Pack close to a Relief Block.
The Accumulator here in the Power Pack is relatively small size containing less than 10 liters of Nitrogen gas to take its role as an shock absorber mainly protecting a sudden stop the Engine mainly caused by overload the Engine.
This is because that, for example, the present pressure is pushing at 150kg/㎠, then, it will be compensate to be 200kg/㎠ when Operating Pressure goes up 200kg㎠ in the same value that oil goes from V/V to an accumulator, then finally oil can be drained to tank when the Engine stops
