Excavators are all earth-moving buckets, and the construction site needs to be crushed. It is really difficult to do without a breaker. Want to install a breaker for dual purposes of digging? Before installing, you need to know these. When buying a breaker, many friends like to ask, what size breaker should my excavator be equipped with, or are all breakers universal? Such a question is easier for friends who are not familiar with this industry Asked, in fact, it is not the case. If you want to connect the excavator and the breaker well, you must choose a suitable breaker to match the excavator.
General model of breaker:
A ton excavator can generally be equipped with a 6-8 kg gun hammer. The specific size should be determined according to the model of the excavator and the usage scenario. There are many brands and models of excavator breakers on the market. The more famous ones are Shuishan, Engineer, Furukawa, etc. In fact, excavator breakers are generally divided into models according to the diameter of the drill rod in the industry. We usually hear " "68 hammer" refers to the breaker with a drill rod diameter of 68mm, and "140 hammer" refers to the breaker with a drill rod diameter of 140mm.
The diameters of common breaker rods are 53, 68, 75, 100, 120, 135, 140, 150, 165 (in millimeters), etc. There are also many types of different brands, let’s take a look below See how big the excavator should be matched with these types of breakers.
①Hydraulic breaker T50 has a drill rod diameter of 70mm, suitable for 4-8 ton excavators
②Hydraulic breaker T70 has a drill rod diameter of 75mm, suitable for 5-9 ton excavators
③Hydraulic breaker T90 has a drill rod diameter of 85mm, suitable for 6-11 ton excavators
④Hydraulic breaker T130 has a drill rod diameter of 100mm, suitable for 9-17 ton excavators
⑤ Breaker T200 has a drill rod diameter of 135mm, suitable for 18-25 ton excavators
⑥ Breaker T250 has a drill rod diameter of 140mm, suitable for 20-32 ton excavators
⑦ Breaker F320, with a drill rod diameter of 155mm, suitable for 28-40 ton excavators
⑧ Breaker F400, with a drill rod diameter of 165mm, suitable for 32-45 ton excavators
At this point, everyone has a good understanding of the adaptation of the breaker! The question that many people have asked "Can a 6-ton small excavator be installed with a 68 hammer" is answered here. The breaker with a drill rod diameter of 68mm may be installed on a 4-7 ton excavator.
Of course, this is just a reference value. A more accurate matching method is to check the pressure and flow required for the normal operation of the breaker, and compare it with the pressure and flow of the hydraulic system of the excavator. If they match, you can install and use it with confidence. .
The matching breaker is too large: this is really a "small horse-drawn cart", the flow and pressure of the hydraulic system of the excavator cannot meet the requirements for the normal work of the breaker. In this case, if the operation is carried out forcibly, the engine and hydraulic system will be seriously damaged. At the same time, the striking frequency of the breaking hammer will also decrease or even fail to strike normally, which will affect the efficiency of the crushing operation.
Matching a breaker that is too small: In this case, there is no harm to the excavator, but the efficiency of the operation will be reduced if the breaker is too small, which is not cost-effective in terms of benefits, and it will also damage the breaker, so it is recommended We match the breaker within the appropriate range.
