The description of sb81 hydraulic breaker

    Hydraulic breakers are referred to as “hammers” or “crushers”. The power source of hydraulic breakers is the pressure provided by excavators, loaders or pumping stations. It can crush stones and rocks more effectively during construction. Work efficiency. The principle of selecting a hydraulic breaker is to select the most suitable hydraulic breaker according to the type of excavator and the environment of the operation. 

    Features of sb81 hydraulic breaker 

    There are many types of hydraulic breakers, and there are many classification methods. According to the operation mode: hydraulic breakers are divided into two types: hand-held and airborne; classified according to working principle: hydraulic breakers are divided into three types: full hydraulic, liquid-gas combined and nitrogen explosion. The liquid-gas combination relies on hydraulic oil and rear-compressed nitrogen to expand and simultaneously push the piston. At present, most of the crushers belong to this type of product; according to the classification of the valve structure: the hydraulic breaker is divided into two types: the internal valve type and the external valve type. 

The advantage of our sb81 hydraulic breaker


    The vibration and noise emitted by the PTEROSAUR breaker is much lower than other similar equipment on the market, providing operators with a better and healthier working environment. The drill-type hydraulic breaker produces splashing material and debris (flaking) during operation. The energy of these sprinklers is extremely harmful, killing people and damaging other equipment. Since the PTEROSAUR breakers work differently, there is almost no splashing material. According to the risk assessment, the safety range of the Fuktron breaker is 15 meters, while the safety range for other equipment working at the same time is 0 meters.

    Low loss

    The technology we use minimizes vibration levels and hydraulic shock effects. The effect is to reduce the wear and tear of the excavator, which in turn reduces maintenance costs and extends service life. After using PTEROSAUR equipment, some of our customers' excavators have been used for more than 20.000 hours.

    Cost effectiveness

    Low loss guarantees that maintenance costs are kept to a minimum. In addition, our breakers have more complete functions than traditional crushing equipment on the market. So you don't have to invest in buying bulky, expensive secondary crushing equipment, saving you time and money.

    High productivity and strong crushing force

    Our impact breakers can be carried directly to the job site, ie to the material to be crushed. You do not need to invest in a secondary reversing device.

     High productivity and productivity

    The PTEROSAUR breaker is characterized by high precision and high frequency, which makes the material crushing and processing more rapid and efficient.

    Feel free to contact us for more information on impact crushers.

How to use and maintain the sb81 hydraulic breaker

    Before using the breaker, you should carefully check whether the bolts on the hammer body and the hydraulic oil pipeline joint are loose, whether the inlet and return valve are fully open, and whether there is any oil leakage in the hydraulic oil pipeline.

    Try not to use the hammer when the cylinder rod is fully extended or fully retracted, because the damage to the cylinder and the car itself will be relatively large. There is also the ability to ensure that the body is placed in a stable position and the drill rod is compacted in the work. There is also the need to put the breaker into the water, so that the seal inside the hammer is too damaged.

    As for the maintenance of the breaker, I think it is relatively simple, but it is also essential. First, the inside of the drill sleeve is filled with butter. Before use and during use, it is found that the drill sleeve does not have enough butter to be filled, which can extend the use time of the drill sleeve. Another important point is the daily inspection of nitrogen pressure. Before using the hammer, use the gauge to measure whether the pressure is normal, because too much nitrogen pressure will cause the hammer speed to slow down or not hammer, and too little blaster will increase the frequency. At the same time, it is also boring, affecting the working efficiency of the hammer.

sb81 hydraulic breaker Installation and disassembly 

    The bucket and the breaker are alternately operated. During the replacement process, since the hydraulic line is easily contaminated, it should be disassembled and installed as follows.

    1. Move the excavator to a flat, mud-free, dusty, and sundries site, turn off the engine, and release the pressure in the hydraulic lines and the gas in the tank.

    2. Rotate the shut-off valve at the end of the boom to 90 degrees to the OFF position to prevent hydraulic oil from flowing out.

    3. Loosen the hose plug on the boom of the breaker and then connect a small amount of hydraulic oil out into a container.

    4. To prevent dirt and dust from entering the oil pipeline, plug the hose with a plug and plug the pipeline with internal thread plug. To prevent dust pollution, the high-pressure pipe and the low-pressure pipe should be tied with iron wire.

——Hose plugs When equipped for bucket operations, the plugs are used to prevent dirt and dust from the hammer from entering the hose.

——Internal thread plug The internal thread plug is used to prevent mud or dust attached to the equipment main unit from entering the oil pipe.

    5. If you want to disassemble the broken hammer, first remove the pin connecting the stick; store the broken hammer outside, put it on the sleeper and cover it with a thin cloth.

    6, the breaker is not used for a long time, please keep the following methods:

1 Clean the outside of the breaker;

2 After removing the steel brazing from the casing, apply anti-corrosion oil;

3 Before the piston is pushed to the nitrogen chamber, the nitrogen in the nitrogen chamber must be sent out;

4 When reassembling, the parts on the breaker should be lubricated before assembly.

    7. If a breaker is to be installed, the process is reversed from the previously mentioned disassembly sequence. If the bucket is used, it is easy to contaminate the end of the hose and the pipe, and the contaminated part should be cleaned immediately (please use hydraulic oil or diesel to clean it).

Packing and Shipping

    The normal package is plywood box or pallet.If container space is not enough,we will use pe film for packing or pack it according to customers special request.

    We will delivery the breakers within 7-10 working days after get the deposit if no special request.

    Standard accessories include two chisel,two hose,one Nitrogen bottle,one Nitrogen charging kit and pressure gauge and one tool box with necessary maintenance tools and operation manuals.
