Vibratory Hammer Glossary - The BRUCE Hydraulic Vibro Hammer, Vibratory Hammer Standard Glossary of Terminology has specially been prepared with the object of unifying the various technical terms and expressions targeted for majority members of construction concontractors on sites who are being involved with BRUCE Pile Hammer and Vibratory Hammer, Vibro Hammer to be operated at the various different vibro hammer operation taking place through the world. We wish and aim that this will be standard in the pile driving industries.
Total 22.
It is literally a total weight of Vibro Hammer, Vibratory Hammer that included firstly the Vibro Hammer itself plus typically a half the weight of Hydraulic Hoses and additional extra weight or special additions and it is measured kg.
It is also called as ‘Dynamic Weight’ by others. It is a vibrating parts of Vibro Hammer, Vibratory Hammer plus pile weight of any soil sticking on pile.
It is measured in kg and it is a important factor creating the Amplitude

Resonance Free Vibro fells on this Vibro Hammer, Vibratory Hammer.
The Frequency range of Variable Moment Vibro Hammers are specified on the average 2300 vpm to conduct its Vibro Hammer work.
When this Vibro Hammer, Vibratory Hammer is started and stopped, it has no Amplitude or Moment are created because this is accomplished with the use of two sets of Eccentric Weights that gives one set is apposing the other set during the secession of start up and stopping.
These Eccentric Weights on vibro hammer, vibratory hammer are, then phased in and out of time each other during the operation creating Amplitude or Eccentric Moment.
This infinite Amplitude control allows for operator to minimize the radial vibration in the near native soil and to maximize the ability of pile by limiting the vibration nearby.
This result can lead the Suppressor creates no Crane line vibration or less vibration known as Resonant Vibration which is commonly believed to occur for a certain Vibro Hammer, Vibratory Hammer.

In general, sand and soft soil are especially suited for Vibro Hammer operation and well graded sand is much easier to vibrate then uniform sand.
Round grains are easier than sharp sand and dense sand has higher penetration resistance than loose sand requiring larger Vibro Hammers, Vibratory Hammers with higher Centrifugal Force to overcome the resistance.
Clay with firm consistence is less suited for vibration and available Amplitude is the major criteria for the ability of Vibro Hammer, Vibratory Hammer to select the piles within planned project.
Vibrating in bigger stones and rocks are impossible to Vibro Hammer, Vibratory Hammer, in the meanwhile, the higher the water content in the soil, the easier it is to vibrate the pile and dry soil have higher penetration resistance than saturated soil that will require larger Vibro Hammer, Vibratory Hammer than it estimated at the early stage for Vibro Hammer operation.

In physics, Resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others.
Frequencies at which the response amplitude is a relative maximum are known as the system’s Resonance frequencies .
Looking at the Vibro Hammer operations, Resonance normally occurs when getting the Vibro Hammer, Vibratory Hammer starting and stopping moment by the movement of hydraulic motors in the Vibro Hammer, Vibratory Hammer that are connected with two or more gears inside the gear box to rotate and to create such as kinetic energy , which is ‘Centrifugal Force’ in terms of Vibro Hammer, Vibratory Hammer, forming some specific type of frequency from cycle to cycle.
Resonance phenomena occur with all types of Vibro Hammer but the Vibros from BRUCE can control its Resonance effect from starting and stopping the Vibro by reducing the Engine speed in order not the Vibro transfers energy radically.
In the Vibro Hammer industry, the resonance free Vibro is equipped with Variable Moment and this Vibro Hammer can have a lot of advantages then Fixed Moment Vibro, in terms of driving Vibro even in the very urbanized area.

It is also called as ‘Static Weight’ by others the weight of non-vibrating parts of Vibro Hammer, Vibratory Hammer that are normally Suppressor, Elastomers and added any extra weight and it is measured in kg.
lt is the amount of pull Suppressor on vibro hammer, vibratory hammer can handle before engaging in safety stops.
More is better but the Crane must be able to apply pulling at radius and it is measured in tons.

Output horsepower of the hydraulic motors is equal to the actual gallons per minute or liter per minutes of hydraulic oil being delivered multiplied by the maximum relief setting of the hydraulic system on vibro hammer, vibratory hammer.
It is important when reviewing vibro hammer hammer specifications that the diesel engine horsepower is capable of providing more power than is required to achieve the required hydraulic horsepower.
Without this horsepower available, it is not possible to maintain frequency to obtain maximum driving forces of vibro hammer, vibratory hammer.

It means that the overall weight of the Vibro Hammer, Vibratory Hammer, Sheet Pile Driver in Combination with its Frequency and Centrifugal Force that helps to drive a pile by crane hanging that vibro hammer, vibratory hammer is driving the piles by crane free hanged.
In physics, it means that the number of cycles or completed alternation per unit time of a wave or oscillation, but in Vibro Hammer terms, it is the vibration per minute (vpm) and speed of rotating eccentric weights to generate centrifugal force on vibro hammer, vibratory hammer.
