What size hydraulic breaker is suitable for the excavator

Published by HuiTong 2023-12-20

We often see some users on the Internet asking about "how big a hydraulic breaker is equipped with an excavator?", such as "how much sledge hammer is equipped with a 20-ton excavator?", "can a 135 hammer and 140 hammer be matched?" and so on.

Common broken hammer drill rod diameters are 53, 68, 75, 85, 100, 120, 135, 140, 150, 165, 175, 185, 190 (in millimeters), etc., and different brands are also subdivided there are many models, let’s take a look at how big an excavator these models of hydraulic breaker should match.

The harm of unreasonable matching of hydraulic breaker and excavator

There is a term in the industry called "cars with cannons", which is used to describe small excavators equipped with overloaded large-scale hydraulic breaker.

 

1. The matched hydraulic breaker is too large:

This is really a "cart mounted cannon", the flow and pressure of the hydraulic system of the excavator can not meet the requirements of the normal working of the breaker. In this case, if the operation is forcibly carried out, it will seriously damage the engine and the hydraulic system, and at the same time, the hammer's striking frequency will also decrease or even fail to strike normally, which will affect the efficiency of the crushing operation.

2. Matching broken hammers that are too small:

In this case, there is no harm to the excavator, but if the size of the breaker is too small, the efficiency of the operation will be reduced, which is not cost-effective in terms of benefit, and there is some damage to the hydraulic breaker, so it is recommended that you match it in a suitable range hammer.
