The cylinder assembly is the heart of the breaker body. It is mainly composed of control valve, piston, seal retainer and In/out nipple.
The piston and the valve are the only two moving parts of a hydraulic breaker hammer.
The piston moves up and down and hits on the tool, while the valve rotates to control the oil flow’s direction. It is the place where movement happens and where the hydraulic power is generated.

The back head is a chamber for storing nitrogen. When placed under high pressure, this nitrogen-filled chamber acts like a damper upon the return piston-stroke. It also works as an impact enhancer when the piston travels down.
Yantai Wangyuan Hydraulic Co.,Ltd. is one of the largest and most professional manufacturer for the hydraulic breaker and spare parts, we can produce diverse types of back head. Our provided back head is manufactured by high precision CNC equipment which imported from Germany, Japan and South Korea. We use the best in class raw material which we purchase from the certified vendors of the market.

The control valve is the heart of the breaker hydraulic system. It is installed in the valve housing and controls piston reciprocation. The hydraulic oil is supplied to hammer through this valve. When upward stroke takes place, the pressure in the back head is released by the control valve and through the outlet. Then the high pressure in the lower chamber pushes the piston upwards.

Diaphragm is the main components for hydraulic breakers accumulator.
A hydraulic accumulator is a pressure storage reservoir. The diaphragm is filled with gas (nitrogen) and is housed inside a chamber. When this chamber is filled with hydraulic fluid, the gas inside the diaphragm starts to compress. Once at a required pressure, the fluid is released and the gas re-expands, forcing the hammer piston down sharply. This all happens hundreds to thousands of times a minute depending on the size of the hammer.

Tool box is a container for storing various tools for hydraulic breaker.
It can be used for a variety of purposes such as production, home, maintenance, fishing, etc. It is divided into mobile type and fixed type. The mobile toolbox is also called a tool cart.
There are screwdrivers, wrenches, nitrogen meters, and screws in the breaker tool box. Necessary accessories for tools such as adjustable wrenches suitable for repairing breakers.
We could supply all brands and models of Hydraulic breaker tool box. It also can be customized based on the special size based on sample or detail drawing.

Hydraulic breaker is a type of construction machinery that is mounted on excavators, backhoes, skid steers, mini-excavators, and stationary plants. Driven by hydraulic power it breaks rocks into smaller sizes or demolishes concrete structures into manageable pieces.
Hydraulic breakers are widely used in mining and landscaping applications. Although it can be both stationary and mobile, the hydraulic breaker is most commonly used as a mobile tool because it is more flexible.
