Unfortunately, you can’t prevent the chisels on a blasting hammer from wearing out over time, especially if you use the hammer heavily. However, there are things you can do to ensure that the chisel on your hammer lasts as long as possible. You can extend the life of the chisel by keeping the demolition hammer maintained as well as possible. Depending on how they are handled and used, chisels on hydraulic demolition hammers are susceptible to damage.
In addition to maintenance, there are many other factors which can prevent the chisel on your hydraulic demolition hammer from breaking. When you know how the chisel on your hammer can break it also helps operators to avoid this. Although the chisels on hydraulic demolition hammers appear to be strong and durable, there are various factors that can cause them to break. Here is a quick summary of aspects which can cause chisels on demolition hammers to become damaged.
AVOID STRIKING WHEN COLD
When it is cold outside, a demolition hammer is more susceptible to fatigue failure. Before you start using the chisel on your hydraulic hammer, you should warm up the hydraulic hammer. This is why you should begin with light demolition work. When the chisel is wet and frozen in particular, it can break on the first strike. That is why you should start slowly and not use the demolition hammer for too long in a single area.
AVOID BLANK STRIKES
Blank strikes happen when the tip of the chisel does not make proper contact with the workpiece, or the chisel receives too little counter-force from the material. This problem can cause the top part of the chisel head to fracture or create cracks in the chisel chuck.
Blank strikes also happen when the tool slips from the work area, or the tool breaks through thin concrete boulders or sheets.
PAY ATTENTION TO LATERAL FORCES
The most frequent cause of breakage of a demolition hammer chisel is when it is subject to lateral forces during use which cause fatigue stress to increase. Any type of lateral force that acts on the demolition hammer while it is being used can cause the tool to flex. Lateral forces occur when the hammer is not used correctly.
Using the machine to lever an object, working at an incorrect angle and using the traction power of the machine are all things you should avoid doing when operating the demolition hammer in order to extend the working life of the chisel and the demolition hammer.
ADEQUATE LUBRICATION
In order to smoothen contact between metal surfaces in the hydraulic demolition hammer, it should be lubricated every two hours. If you do not lubricate the hammer shaft frequently enough, it can lead to problems and cause the hammer to fracture. When you follow the recommended service schedule, the hammer and chisel will last considerably longer.
AGEING
Many demolition hammers are used too infrequently. Hammers can get rusty over the course of time due to the effects of the weather and because insufficient grease has been applied between uses. This not only causes rust on the outside of the hammer, but also rust inside the housing due to condensation. In a previous blog, I talked about how a demolition hammer should be stored in a vertical position to avoid unnecessary damage.
