Vibro Hammer Glossary

It is also called as’ Normal Frequency Vibro Hammer, Vibratory Hammer’ or ‘Standard Vibro Hammer, Vibratory Hammer’ by many others among Vibro Hammer manufacturing company.
The Frequency range of Fixed Moment Vibro Hammers are specified on the average between 1600~2200 vpm to conduct a standard Vibro Hammer work.
Regardless of Fixed Moment type or Variable Moment type, all the Vibro Hammer, Vibratory Hammer is consisting of three main components, which are Suppressor Housing, Gear Box Assembly and Clamp Assembly.
The Eccentric Weights on Vibro Hammer, Vibratory Hammer In the Gear Box rotates in a vertical plane to create vibration driven by hydraulic motors mounted on Gear Box Assembly where two of both are connected each other to keep them a proper synchronization that creates vertical vibration.
Thus the vibration pn Vibro Hammer, Vibratory Hammer can be transmitted into pile being driven by means of Clamp.

Adding an Extra Weight to the Static Weight of Vibro Hammer, Vibratory Hammer can increase the Vibro Hammer performance resulting in more deeper and faster penetration especially, when the Vibro Hammer need to vibrate a firm clay soil although it is less effective in sand.
This is because the Centrifugal Force on Vibro Hammer, Vibratory Hammer must overcome its resistance under the pile, where the friction of clay soil would be reduced by the Amplitude.
In general, unfavorable result can be brought in sand when a total static weight of Vibro Hammer, Vibratory Hammer is more than the Dynamic Weight of Vibro Hammer, Vibraotry Hammer.

It is aimed at relatively small Vibro Hammer, Vibratory Hammer can be mounted on the Excavator to enhance the mobility to be light and fast with agile transportation to the task compared with Crane Suspended Vibro Hammer, Vibratory Hammer.
It has no additional Power Pack, in stead, It is necessarily to pick up the Hydraulic source from an exacting Excavator the customers owned.
Excavator Mounted Vibro Hammer, Vibratory Hammer provided by BRUCE boasts a high punctuality rate to the Vibro Hammer task with hydraulically rotating at 360 degrees to make piles positioned for more precise method of operation.

It is called as ‘Clamping Force’ by BRUCE Vibro Hammer, Vibratory Hammer.
It is the area of piston rod head of the clamp multiplied by the available Clamp Pressure of the Power Pack.
The Clamp Force is very important to the life of Jaws of the Clamp and ensureing pile hold when moves and driving the piles by vibro hammer, vibratory hammer.

This is the first key factor in Vibro Hammer performance.
The Eccentric Moment must create big enough Amplitude to exceed the elastic range of various soils.
If Eccentric Moment at vibro hammer, vibratory hammer is bigger, the Amplitude will be automatically the same in Vibro Hammer performance.
The Eccentric Moment is described the effectiveness of a force to produce rotation about an axis.
It is the value that is equal to the weight of the Eccentric Weights multiplied by the distance from the center line of gravity to the center line of rotation and Then multiplied by the total number of Eccentric Weights used in the Gearbox.

It is also called as ‘Elastomer Rubber’ on just’ Rubber’ by many others.
When upward vertical vibrations created by the rotating Eccentric Weights in the Vibro Hammer, Vibratory Hammer, the Elastomers attached on the Suppressor Housing absorbs the vibration imparted by the Vibro Hammer, Vibratory Hammer and prevent damage to the Crane boom.
It should be periodically inspected when Vibro Hammer, Vibratory Hammer is being used regularly.

It is important key factor that decides the performance of Vibro Hammer, Vibratory Hammer, Sheet Pile Vibrating Hammer and toher vibrating machine.
It is generated by rotating Eccentric Weights inside the gear box shaped of vibro hammer, vibratory hammer like a half moon and it is connected with other components by Gears and Shaft to create the moment.
A small increased speed can be turned out a large increasingly developed Centrifugal Force and this force is generally measured in tons by BRUCE Vibro Hammer, Vibratory Hammer.

It is one of main part of Vibro Hammer, Vibratory Hammer attached to on bottom of Vibro Hammer body to conduct a practical Vibro Hammer operation after it grabs the piles.
The clamp contains two gripping jaws, one is “fixed” and one is “moveable”.
A large hydraulic cylinder in the clamp body of vibro hammer, vibratory hammer operates the moveable jaw with up to designed power tons of clamping force depending on clamp pump relief pressure.
The jaws open and close by turning a switch on the remote control pendant at vibro hammer, vibattory hammer, or may be operated by turning the switch at the main control panel, mounted behind one of the doors on the power unit.
The check valve automatically operates the clamp flows either the direction Close or Open.
Clamp types and sizes provided by BRUCE Vibro Hammer, Vibratory Hammer are varied, among them the Universal type, which is also called as ‘Single Clamp’ and Caisson Clamp which is also called as ‘Double Clamp’ are the most representing Clamp released by BRUCE Vibro Hammer, Vibratory Hammer.

It is called as ‘Steel Tube Pile’ or ‘Tubular Pile’ by many workers on sites, but the leading reason for calling a Caisson Pile is that its for typically in the Caisson foundation by using the Vibro Hammer or Vibratory Hammer operation.
This pile is manufactured in seamless spirally welded or well lap-welded and is normally installed by top driving but in difficult ground conditions and also it can be installed by a combination of drill and drive. This pile is born as a watertight retaining structure used for, for example, to work on the foundation of a bridge pier, for the construction of concrete dam or for the repair of ships.
These are constructed such that the water can be pumped out, keeping the environment dry and is sunk into the ground to some desired depth and then filled with concrete thus forming a foundation that this is because Caissons can be floated to the job site.
The types of Caissons are varied like Box type, Excavated type, Open type, Pneumatic type and Caisson Sheet Pile.

It is also called as ‘Raked Pile’ or "Inclined Pile".
A pile driven by vibro hammer, vibratory hammer or other pile driving equipment on angle driving in an angle to the vertical, and it is normally used for counteracting its horizontal force acting on vertical piles
