Principle of excavator hydraulic breaker

The power source of the excavator hydraulic breaker is the pressure oil provided by the pumping station of the excavator or the loader, which can more effectively clean the floating stones and the soil in the cracks of the rock in the role of excavating the foundation of the building. The principle of selecting a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the operating environment.

The excavator hydraulic breaker has become an important work tool for hydraulic excavators. Some people also install the excavator hydraulic breaker on the backhoe loader (also known as busy at both ends) or wheel loader for crushing operations. Hydraulic breaker is also called hydraulic breaker or hydraulic rock breaker.

This term is often used in Japan and South Korea. It is also called hydraulic hammer, which is often used by companies in Finland and Germany. Chinese manufacturers and users, some call them hydraulic breakers, and some call them hydraulic picks, hydraulic guns, gun machines, crushing heads, woodpeckers, and so on. Although the names are diverse, they all refer to the same machine. This machine uses hydrostatic pressure as the power to drive the piston to reciprocate. When the piston strokes, it hits the drill rod at high speed, and the drill rod crushes solids such as ore and concrete.

Characteristic

Impact energy enhanced structural design

The excavator hydraulic breaker adopts the optimized design concept, increases the stroke of the piston and cylinder, and adopts the same large diameter as the piston and drill rod to make the breaker

It has the best matching effect with the main engine, reasonably utilizes the highest output energy, saves energy, and achieves the highest work efficiency.

The use of high-quality materials and special precision technology processing and manufacturing.

The materials of important parts such as piston, main body bolt, main body front part, cylinder, main body rear part, etc. have passed the strict quality inspection of HALL company, which can guarantee the highest quality. The main components such as the piston, the front part of the main body, the oil cylinder, and the rear part of the main body are manufactured using the latest heat treatment equipment, and many years of technical experience ensure the stability of excellent quality. HALB hydraulic breaker has been invested in multiple facilities to set up special MCT (Universal Machine Tool Center), CNC (Numerical Control Machine Tool) and large-scale grinding machines for the breaker to realize the automated manufacturing process and stabilize the quality. In particular, use a large-scale inner diameter grinder for breakers to process the cylinder and the inner side of the valve as a finished product at one time to ensure centering and improve accuracy. With special super processing and inner diameter grinding operations, the surface roughness and product completion are improved.
