Working principle of impact hammer

The impact hammer is a type of piling equipment that uses impact force to penetrate piles into the ground. It consists of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical leaders (commonly known as gantry) at the front of the pile frame, and is lifted by a lifting hook.

Hydraulic accumulator

OverviewTypes of accumulatorsFunctioning of an accumulatorSee alsoExternal links

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage
