How to choose the right hydraulic breaker for your excavators?: 

• 1. The weight and bucket capacity of the excavator. The weight of the excavator is fully considered to avoid the excavator tipping over due to the overweight sledgehammer when the arm is fully extended. If the selected hammer is too large, it may cause the excavator to capsize. If it is too small, the excavator can not be used at the same time, which will aggravate the damage of the large  hammer. Only when the two counterweights are matched can the excavator and the crushing hammer be fully functional.

• 2. The flow rate of small hydraulic hammer can be as low as 23 liters/minute, while the flow rate of large crushing hammer can be as high as 400 liters/minute. When selecting hydraulic hammer, the flow requirement of hydraulic hammer must be consistent with the output flow of excavator backup valve. The flow rate determines the working frequency of the hydraulic hammer, that is, the number of impacts per minute, and the flow rate is proportional to the number of impacts. When the flow rate of a large hydraulic system is too large and the output power of the hydraulic system is too large, the hydraulic system will generate too much heat.

• 3. Hydraulic hammer adopts vehicle-mounted structure. At present, there are three common designs for large hydraulic hammers, namely triangle, splint and box (also known as silent type). Triangle and splint types typically use two thick steel splints to protect the sides of the hammer core. This structural design cannot keep the hydraulic hammer stable in front and back. Their disadvantages are that the box hydraulic crushing hammer of the same tonnage makes a larger sound, the steel plates on both sides are easy to loosen or break, and the hammer is not well maintained.

• The structure of box-type large crushing hammer is: the shell completely surrounds the hammer body, and the shell is equipped with shock absorbing materials, which can reduce the impact force and form a buffer between the hammer body and the shell. The advantages are better maintenance of the hammer, less noise, less bracket vibration, and the solution to the problem of shell loosening.
