A hydraulic breaker tool is an excavator-mounted percussion hammer used for demolishing hard structures. It is powered by the auxiliary hydraulic system of the excavator and is controlled by a foot-operated valve. Demolition crews use this tool when a jackhammering job is too large or where blasting isn't practical. The Association of Equipment Manufacturers has published a manual for the safe use of hydraulic breakers.

Impact of cold temperatures on hydraulic breaker tool

The hydraulic breaker is an important working tool of hydraulic excavators. It is used for crushing, impact, and hammering of rock and soil. Since the breakers are used extensively in different industries, it is essential to use and maintain them correctly. The following are six common failures of hydraulic breakers.

The hydraulic breaker oil circuit should be cleaned, and the cylinder body should be inspected for damaged diaphragms. The hydraulic breaker must also have the nitrogen pressure balanced. If the oil leaks at the cylinder body, tightening the oil circuit joints can repair the problem.

In order to simulate the dynamic behavior of hydraulic breaker tools, it is necessary to model their hydraulic flow. This is done by using mathematical models using commercial software SimulationX. The resulting model includes accurate control volumes for parts that change with pressure. The hydraulic fluid transfer system components are also subject to repetitive tests, which are reflected directly in the analytical model. This minimizes the risk of miscellaneous errors.

Maintenance of hydraulic breaker tool

Hydraulic breaker tools need routine maintenance to keep them performing at their best. It is important to keep them clean and lubricated, as well as to inspect the internal components and fasteners. Regular visual checks will detect worn items and potential failures, including worn bushings and bolts. If a tool feels loose or becomes stuck, stop working immediately and check the condition of the tool.

To grease the tool, apply a lithium-based grease rated to 500 degrees Fahrenheit. This grease is specially formulated for use in higher temperatures, and it will stay between the steel and bushings for better lubrication. You can apply the grease manually, or you can also use an automatic greaser. Different types of grease are available for different types of hydraulic breakers, and you can choose a grease that best suits your needs.

Hydraulic breakers are prone to fluid leakage, so it is vital to maintain them properly. This means that the breaker should be stored in a climate-controlled location, and the hydraulic seals must be properly maintained to prevent fluid leakage. The hydraulic ports should also be capped to prevent any dirt or debris from getting inside, as this could cause distorted seals and fluid leakage.

Proper lubrication prolongs life of breaker cylinder

Lubrication is essential to the life of hydraulic breakers. It performs a two-phase job by protecting the internal components and extending breaker cylinder life. Proper lubrication is equally important as following the guidelines for the operation of hydraulic breakers. Using improper lubrication can result in the same wear as not lubricating at all.

Proper lubrication also reduces friction and wear. The constant up and down cycling of a hydraulic breaker leads to unnecessary wear and tear. This wear reduces effectiveness, reduces the life of the breaker, and can lead to internal damage. Proper grease will minimize friction and wear and maximize the hydraulic breaker's lifespan.

Lubrication should be done several times a day to maintain optimal performance. The industry standard is to re-lubricate every two hours, although your own regular inspections may indicate you should do so at a shorter interval. To check if the breaker needs grease, check its bottom bushing to ensure that a grease film is formed.

Application of hydraulic breaker tool

The hydraulic breaker tool is one of the most common and versatile tools used in the construction industry. This powerful tool is usually connected to an excavator and is very quiet compared to other tools. It also has the advantage of being easily connected to a variety of power sources, such as trucks, excavators, skid steer loaders, tractors, and more. In fact, you can purchase one hydraulic breaker tool for the same price as two pneumatic ones!

Hydraulic breaker tools should be used with care. Always operate with a spotter or an experienced operator. This will minimize the risk of injuries or unwanted fissures. It will also help to prolong the tool's life. If the tool is used improperly, it can cause “blank-firing,” which occurs when no object accepts the force of the breaker. The shock from blank-firing is redirected back up the tool shank.

In addition to the hydraulic breaker tool, you should consider other attachments. Using the right one for the application you're performing is essential. There are other tools that can assist you in breaking large pieces of rock. Chisels are particularly useful for this purpose because they direct force in a specific directional pattern.
