Tips to Get the Most Out of Your Excavator Rock Breaker

Best used for digging and moving large objects among various other tasks that they perform, excavators are widely used in Quarry, Urban construction, Infrastructure, house building, road construction, landscape engineering, mining and so on. They offer excellent performance and versatility at the jobsite due to the various attachments. In fact, it is these various useful excavator attachments that make them reliable enough to handle various tasks in different working environments. Also, these attachments add to the overall productivity of the excavators. Amongst the various attachments, excavator-mounted hydraulic rock breakers deserve a special mention.

Also called as hydraulic hammers, rock breakers are best for breaking hard objects like rock, concrete, asphalt and other construction and aggregate materials. Rock breakers are powered by the hydraulic energy. A hydraulic hammer to break rocks and a robust housing bracket are two major components of the rock breakers.

Getting the best out of your excavator rock breaker

Excavator-mounted rock breakers are designed in such a way that they can withstand toughest operating conditions, However, their excessive usage can result in wear and tear. So, in order to achieve the most from the excavator-mounted rock breakers, their maintenance is very important as without that there might be project delays, wastage of time and money and the lifespan of the attachment may also reduce. So, here are some top tips through which you can get the optimal performance, increase the life of your excavator rock breaker and get the most out of it...

Visual inspection is necessary: In order to check the rock breaker for any wear and tear, visual inspection after every use is a must. However, this step is often overlooked but this should not happen as thorough visual inspection, you can easily identify any worn or damaged components on time and prevent unexpected downtime. Hydraulic hoses, the breaker Housing, attachment pins, Chisel pins and locks and the tool point for any cracks or gouges should be considered in the visual inspection checklist.

Hydraulic hoses should be examined carefully: You need to check that the hydraulic hoses from the excavators are of correct length and always routed properly. This is because hoses that are short in length restrict attachment extension and hoses longer in length can become disengaged on rebar and other debris.

The importance of greasing the excavator-mounted rock breaker: Greasing at regular intervals assumes lot of importance because it helps in lubricating and clearing the tool bushing area of debris. For greasing, the manufacturer’s recommendations must be followed. This is because if the grease is added before properly positioning the breaker, it could lead to seal damage or even a catastrophic failure and too little grease could cause the bushings to overheat, seize and damage tools. So, in the best case scenario, greasing should be done every one to two hours to reduce build-up, tool wear and bushing wear.

Checking the nitrogen pressure: It is important to maintain proper nitrogen pressure in rock breaker Head cap and accumulator, and this depends on the application and outside working temperature. As a matter of fact, the nitrogen level required for breaking rocks is different from what is required for breaking concrete in a parking lot. Here, the attachment’s operation and maintenance manual can come to help as it will have the details about the nitrogen pressure setting for your application and working temperature.

Regular checks are also needed: The hydraulic breaker is percussion equipment, the bolts and nuts can easily become loosened, which is the cause of severe damage to several component parts. Thus, check torque of nuts, bolts periodically, as per the guidelines shared by manufactures. Regular checking of the wear status of the chisel, bushes and chisel pin is very important as excessive wear of bushes and chisel can cause chisel head and piston damage.

Regular servicing is the key: If the rock breaker is serviced regularly, its durability can increase considerably. However, if there are issues, rock breakers can be repaired or rebuild to give the best results.
