Now, let’s provide a detailed explanation for you on how to determine the appropriate size of the excavator to match with the size of the breaker hammer: This question may seem quite “elementary” to those with some experience, but for users who are new to excavators or those planning to install the breaker hammer, it can also become a major challenge.
No.1 The general model of a breaker hammer：
There are many brands of excavator breakers on the market, such as Yite, Gongbing, Atlas Copco, Gohai, etc. Each brand has its own naming convention for the breakers, and new buyers may be completely confused by it.
However, in the industry, excavator impact hammers are generally classified by the diameter of the shank. The term “68 hammer” we often hear refers to an impact hammer with a shank diameter of 68mm, and “140 hammer” refers to an impact hammer with a shank diameter of 140mm.
The diameters of common breaker hammer shank rods are 53, 68, 75, 100, 120, 135, 140, 150, 165 (all in millimeters), etc. Different brands also have many different models. Now let’s take a look at which excavators these models of breaker hammers should be matched with.
Now everyone should have a clear understanding of the compatibility of the breaker hammer, right? Many people had the question “Can a 6-ton small excavator be equipped with a 68mm breaker hammer?” Here, the answer is provided. A 68mm drill rod breaker hammer can possibly be installed on an excavator weighing 4 to 7 tons. Of course, this is only a reference value. The more accurate matching method is to check the pressure and flow required for the normal operation of the breaker hammer, and compare them with the pressure and flow of the excavator’s hydraulic system. If they match, then it can be installed and used with confidence.
No.2What are the hazards of an improper match between a breaker hammer and an excavator?
The matching breaker is too large: This is truly a case of “a small horse pulling a large cart”. The flow and pressure of the excavator’s hydraulic system cannot meet the requirements for the normal operation of the breaker. In this situation, if operations are carried out forcibly, it will seriously damage the engine and hydraulic system, and at the same time, the impact frequency of the breaker will decrease or even fail to function properly, affecting the efficiency of the crushing operation.
Too small matching for the breaker: In this case, it doesn’t cause any harm to the excavator. However, if the breaker model is too small, the efficiency of the operation will decrease, which is not cost-effective in terms of benefits, and it will also cause some damage to the breaker. Therefore, it is still recommended that everyone match the breaker within the appropriate range.
