From multiple perspectives, finding the right circuit breaker for the project needs is important, including equipment life and safety.
Among all the tools and machines that make construction and demolition possible, the most commonly used one is the hydraulic breaker. This is because the hydraulic breaker has a high level of breaking force and can pass through the material quickly. They also require minimal daily maintenance, which makes them a cost-effective option with minimal downtime.
The size of the circuit breaker that can be installed on the mobile bracket ranges from a 26,000-pound bracket to a 99,000-pound bracket. After the initial use of large and heavy breakers to start the demolition process at the construction site, smaller breakers can be used to break concrete materials before screening and crushing. The material can then be recycled or reused.
The total number of hydraulic breakers may vary depending on the level of production, the type of material being removed, and the entire scope of operation.
Without hydraulic breakers, workers will rely on alternative practices that may affect productivity and project costs. For example, hydraulic demolition will produce a large amount of waste water, and the cost of treating this waste water may be very high due to the need to take special treatment measures.
The other options of swelling agent or abrasive jet are time consuming and inefficient, especially when you consider how many times you might need to reduce the material. This can result in a lot of downtime and drastically reduced productivity.
Heavy equipment dealers usually know demolition equipment (including breakers) very well, so they are a good resource for finding the best model for your carrier (usually an excavator or fixed arm system).
More likely, they will provide specifications and information about circuit breakers of various sizes to help determine the best model. But being familiar with what to look for in a circuit breaker can simplify the selection process.
The best place to find circuit breaker information is the manufacturer's manual, website, user manual or catalog. First, you need to carefully check the carrier’s weight range. A breaker that is too large for the carrier can cause unsafe working conditions and cause excessive wear of the carrier.
The super breaker also transmits energy in two directions, towards the material and through the equipment. This generates energy waste and also damages the carrier. However, using a breaker that is too small will exert excessive force on the tool steel, thereby transferring impact energy from the breaker to the material.
Using a circuit breaker that is too small will damage the installation adapter and internal components, thereby greatly shortening its service life.
Once you find a circuit breaker that meets the operator's capacity, check its output power, usually in feet-pounds. Remember, the foot-pound rating is a generalization, not based on any physical test.
Everyone likes the story of David and Goliath; however, this does not apply to circuit breakers and building materials.
Using a breaker that is too small for the material can cause the device and hydraulic oil to overheat, which can cause the tool steel to melt, seals, and even the carrier itself.
This is a good rule of thumb: if you use the circuit breaker in one place for more than 30 seconds without seeing penetrations, dust, cracks or cracks, the circuit breaker is too small. You either need to reposition the carrier to the material or use a larger circuit breaker.
Keeping this rule in mind, you will save maintenance and replacement costs, and extend the life of the circuit breaker.
Usually the output of a circuit breaker is recorded in one of two ways: as a foot-pound rating calculated by the manufacturer or as a foot-pound rating measured by the Association of Equipment Manufacturers (AEM).
Foot-pound ratings can be deceptive because they are roughly based on the weight of the circuit breaker used rather than the results of any physical testing.
The AEM grade measures the force exerted by the breaker in a single blow through a repeatable and certified test method. The AEM rating is developed by the Bureau of Installed Circuit Breaker Manufacturers, and it is easier to compare circuit breaker models by viewing the real data collected during actual testing.
For example, three breaker manufacturers may all claim that their breakers are in the 1,000-pound breaker class, but the AEM test standard may show that these three breakers actually have smaller foot-pound impacts. If the manufacturer provides a disclosure statement, or if the circuit breaker has an AEM Tool Energy seal label, you can determine whether the circuit breaker has been AEM tested.
If you cannot find this information, please contact the manufacturer. Manufacturers also often provide productivity estimates for different types of aggregates.
In addition to weight and output power, check the installation package of the circuit breaker. There are two key points to install the breaker on the bracket: hydraulic installation kit and installation components.
The breaker requires a unidirectional flow of hydraulic pipes to transport the oil from the carrier to the breaker and then back. As long as the size of the components can correctly handle the required flow and pressure, the unidirectional flow hydraulic kit is sufficient to power the circuit breaker. However, if you plan to use the same bracket with other accessories that require two-way flow, you can consider a two-way flow hydraulic kit.
When pairing the breaker with the hydraulic system, the hydraulic flow and pressure specifications also need to be considered. If the carrier cannot provide sufficient flow under the proper pressure, the breaker will not be able to operate at its maximum output, which will reduce productivity and may damage the breaker. In addition, circuit breakers that receive too much traffic wear out quickly, shortening their service life.
For best results, please follow the hydraulic breaker specifications in the user manual, catalog and manual. You will find out if the circuit breaker has additional systems that may require additional maintenance.
Some breakers have a nitrogen assist system that works with hydraulic oil to accelerate the breaker's pistons. It is necessary to follow the specifications of the nitrogen system to ensure that the power output of the circuit breaker is consistent.
As for mounting components, a bracket or pin and bushing kit is usually required to connect the circuit breaker to the bracket.
Usually, they are bolted to the top of the circuit breaker and configured to match a specific carrier. Some manufacturers produce universal mounting brackets that can accommodate two or three different sizes of carriers.
When traditional excavation methods and impact systems are difficult to achieve the expected results, Atlas Copco's DC drum cutter connection line in Paris, New Jersey provides contractors with an economical solution. Contractors can use attachments for surface analysis, trench digging, frozen soil removal, excavation and demolition. They can also work up to 98 feet underwater without additional components.
Eight attachments weigh 440 to 6,395 pounds and can be used with brackets from 1 to 50 tons. The cutter drum on the device has an optimized picking mode to achieve high productivity, and because the produced particle size is small, chopped rock or concrete can be used as backfill material without additional crushing.
The DC drum cutting machine series are equipped with high-torque gear motors, which can improve productivity and motor durability. The sturdy spur gear provides the best energy transmission with the lowest service requirements, and the sturdy housing design with Hardox wear-resistant protection increases the uptime of the equipment. The drum cutter is equipped with a central fixing bolt, and the operator can rotate the equipment 360 degrees for easy positioning.
Atlas Copco's roller cutting technology can remove materials from tunnels, ditches and any other types of rock or concrete surfaces. They operate with minimal noise and vibration, allowing safe use in a wide range of applications, including restricted construction sites and sensitive urban areas. The DC drum cutter is a complementary product to Atlas Copco's hydraulic breaker, which is ideal for soft rock applications that require 14,500 pounds per square inch compressive strength.
With the help of adjustable pins, bushings or other components in these universal brackets, the circuit breaker can be adapted to a variety of brackets.
However, the different distances between the pin centers can complicate the connection with the quick coupling system. In addition, when the circuit breaker is not in use and removed from the carrier, loose parts (such as gaskets) may be lost.
Some carriers are equipped with a quick coupling system, which requires the installation interface of the circuit breaker to be configured like the original accessory. Some manufacturers produce top mounting brackets that mate well with the coupler.
Reviewing the after-sales support of manufacturers and distributors can also help narrow the selection of circuit breakers.
As part of after-sales support, some distributors and circuit breaker manufacturers provide on-site or factory training on the installation, use and maintenance of circuit breakers.
It is also a good idea to check the breaker tools provided by dealers and manufacturers. For any operator doing extensive demolition, the three must-haves are chisels, chisels, and blunt tools.
The rubbing point is shaped like a pencil and is very suitable for breaking hard concrete reinforced with steel bars and removing bricks. The operator can put the narrow tip of the tip into the crack and between the steel bars to separate the material.
The chisel tip looks similar to a screwdriver and will give you the best splitting action. It has standard width and wide width to choose from. The blunt point has a flat surface and a larger surface area, which can produce greater impact when slab concrete is destroyed.
Regular maintenance of circuit breakers is necessary, but it is one of the biggest challenges in construction and demolition operations. The circuit breaker needs to be lubricated with sufficient grease to keep the tool bushing area clean and reduce friction. Make sure to follow the manufacturer's recommendations.
Adding grease before the breaker is properly positioned can cause seal damage or even catastrophic failure-while too little grease can cause the bushing to overheat, jam and damage the tool.
The manufacturer recommends the use of high molybdenum grease that can withstand operating temperatures above 500 degrees Fahrenheit. Some breakers have automatic lubrication systems that manage grease levels, but these systems still need to be checked to ensure that there is enough grease. The shiny mark on the tool indicates that the breaker is not properly lubricated.
You should check the fixing pins of the device to look for oil leaks and any loose or damaged bolts, which can quickly turn a small problem into a big one.
For long-term maintenance plans, please consult the user manual to find the required regular maintenance intervals to avoid unnecessary downtime.
If you know how to choose the right equipment, you will have reliable tools for your construction and demolition operations in the next few years.
Choosing equipment that will not exceed your budget due to maintenance costs and expensive downtime is the key to maximizing profitability.
