286 Choosing the right rockbreaker Contractors should match their equipment to the requirements of their carrier and then to the application of the job. The biggest breaker, to get the job done fast, may not be the most practical. Consider the sizes that will be the most appropriate to your particular applications in construction, quarrying or demolition. B efore acquiring any breakers, it is imperative to know how much hydraulic oil pressure and fl ow your machine has. This will determine the size of the breaker to be fi tted. Once you have purchased your breaker, it is imperative that preventative maintenance is adhered to. Regular lubrication and replacement of worn bushes and damaged retaining pin is essential. If the top and bottom bushes and tools are not replaced within the manufacturers wear limits, uneven striking will occur between the end of the tool and the piston. This will lead to early failure or damage to the piston and undue shock to the rest of the breaker.” It is also recommended that the correct tool is used for the job. For instance using blunt tools in quarrying and mining, as hard rock needs to be broken by impact, chisels for general purpose work, such as trenching, house pads and swimming pools and moils for demolition and concrete work. Longer tools can be an advantage through deeper penetration and by the way they keep dirt away from the lower bush. Lubrication of the breaker should be carried out on a regular basis. Lubrication can be carried out manually with a grease gun or automatically with a Lincoln Lubrication system. It is essential that the breaker is regularly greased to eliminate bush & tool wear with a good quality grease.
