When to Use hydraulic breaker for mini excavator？

There are innumerable industries that use excavation. Construction, mining, agriculture, and oil and gas exploration are just a few of the major ones.

Like most jobs, doing excavation well requires having the right tools. For instance, hydraulic hammers are used for breaking up hard materials. They are particularly useful when traditional excavation techniques do not suffice.

This article covers the basics of hydraulic hammers for mini-excavator projects. Keep reading to find out the many advantages they have to offer.

Hydraulic Hammer Basics

Hydraulic hammers are often called “hydraulic breakers” or “percussion hammers”. They are robust tools that can demolish stone, asphalt, concrete, and other hard materials.

Hydraulic hammers come in a variety of sizes. Many larger, more powerful ones require heavy-duty excavators. However, you can use smaller hydraulic hammers with mini-excavators.

Check Compatibility

First, you need to ensure that the size and weight of the hydraulic breaker are compatible with the mini-excavator. In general, the hammer should weigh no more than 10 percent of the excavator’s weight.

It is also vital to check the excavator capacity for hydraulic pressure and flow. It needs to be able to meet the demands of the hydraulic hammer.

Advantages of Using Hydraulic Hammers for Mini-Excavator Projects

There are many advantages of using hydraulic hammers with mini-excavators. Here are the main ones to consider.

Compact Size

One of the biggest benefits of using a hydraulic breaker with a mini-excavator is its compact size. This can be ideal for job sites that do not support larger machines, including in urban areas or other confined environments.

They also offer better maneuverability on a work site. It could mean being able to reach and break up hard materials in tight spaces that you otherwise may not be able to access.

It is easy to see how all this can translate into greater efficiency. It also means not having to use manual labor to complete the job.

Increased Precision

Imagine trying to remove brick mortar with a jackhammer rather than a chisel. It will do the trick but is likely to damage the surrounding bricks.

Similarly, smaller hydraulic hammers can offer a level of precision not achievable by larger breakers. This can allow you to tackle jobs that require a higher level of exactness or care while avoiding collateral damage.

Ease of Use

Unlike larger, more cumbersome breakers, smaller hydraulic hammers attach easily to mini-excavators. This can be particularly useful on sites where you are often switching attachments, and can lead to greater efficiency when shifting between jobs.

Power

Smaller does not mean weaker. In fact, hydraulic hammers for mini-excavators can pack a lot of power, especially relative to their size. You can find breakers that fit smaller excavators that produce as much as 1,500 foot-pounds of torque.

Hydraulic Hammers/Breakers

There are times when an obstacle prevents normal excavation from occurring. Used in mining, quarries, excavation, and demolition, the hammer/breaker is brought in to chip away at large boulders or existing concrete structures. There are times when blasting is used to remove obstacles or breakthrough thick layers of rock, but hammers offer a more controlled process.

Breakers are driven by a hydraulic piston that exerts pressure on the head of the attachment to provide a powerful and consistent thrust into the obstruction. In simplest terms, it’s just a really really big jackhammer. Great for tight spaces and continuous production, breakers are also much quieter and create less vibration than blasting.

Follow All Precautions

Still, these powerful tools still need to be handled with the care and safety of any industrial machine. An experienced operator and spotter working in tandem will reduce injuries or unwanted fissures during operation. Understanding how the machine works will also prolong the lifespan of the breaker/hammer.

Blank-firing is when there is no object or material to accept the force of the breaker. So the piston fires into the tool shank, but that energy can’t be absorbed by dead air. The shock is sent back up the tool and crashes into other shocks being sent down the tool.

That’s a lot of force meeting in the middle which will cause undue stress and wear on the tool itself. This is where experience comes into play. By anticipating the “break” of the obstacle, an operator can stop the breaker just before the intended piece falls away. This limits the number of blank fires, protecting the tool.

As with all machinery, the breaker should be inspected before and after every use to ensure good working conditions. Unusually worn components should be addressed and the operator needs to make sure the proper amount of lube or grease is being used. During operation, make sure the following processes are followed for safety. For the tool, the operator, and other personnel in the area, make sure to consult the OEM users manual for correct operation.

General Rules

• Only run a breaker or hammer from the operator’s seat to ensure maximum control
• Be aware of flying debris – use protective eyewear, make sure protective window or screen is available for operator
• When installing/removing attachment, be mindful of pinch points
• Make sure safety decals and signage are clean and legible
• Use the right size attachment for the job

Operational Precautions

• The breaker/hammer must only be used perpendicular to the object
• The use of the attachment should never lift the excavator off the ground
• The head should always be able to move freely
• Work from the edges of the obstruction, never the center
• When working in a trench, never allow the breaker to hit trench walls

For intended uses only

• Never hit the same spot for 15 seconds straight
• Never use the breaker/hammer attachment to lift something
• Never use the breaker/hammer to move a rock
• Never use the breaker/hammer as a pry bar
• Never submerge the breaker/hammer into the water at depths you can no longer see the tool

When to Stop Operation

• When hydraulic hoses begin to rattle violently – the energy chamber needs repair
• When the point, chisel or spade stops moving – the tool may have seized
• When hydraulic oil begins to leak – gaskets or other parts may be too worn for operation
