Q What is a hydraulic breaker on a excavator?
A A breaker is a powerful impact hammer mounted on an excavator or skid steer for the demolition of concrete structures or rock. It is powered by the excavator/skid steer's auxiliary hydraulic system, which is equipped with a foot valve for this purpose.
Q How do I choose a hydraulic breaker?
A Instructions for choosing a hydraulic breaker from a variety of models and brands. 1. Weight of the basic machine. The hydraulic breaker should not exceed 10% of the weight of the base machine. 2. Oil flow rate. ... 3. Working pressure. ... 4. Productivity. ... 5. Construction. ... 6. Ease of use and maintenance ... 7. External noise and vibration.
Q Which rock breaker is best?
A For hard materials, we recommend a 7,500 to 10,000 ft-lb breaker, and if high production is required a 13,500 ft-lb breaker would be beneficial. CONCRETE BREAKING: When breaking concrete, the hammer must penetrate the material so that it cracks and separates from the reinforcing steel.
Q What's the principle of hydraulic breaker?
A The piston is moved by the high and low pressure of the hydraulic oil to hit the chisel, and then the chisel hits the stone for crushing work.
Q What's the different among three models breaker?
Top Type: 1. easy to locate and control 2. More conducive to excavator 3. Weight lighter, the lower risk of broken chisel
Box Type: 1. Reduce noise 2. Protect the enviroment
Side Type: 1. Overall length shorter 2. Hook back things conveniently 3. Maintenance free
Q What's main parts of hydraulic breaker? And how about their fundation?
Cylinder: This contains the moving piston which strikes the tool. The seals for both ends of the piston are also located in the cylinder. The seals for the upper end of the piston are located in a removable seal retainer while the seals for the lower end of the piston are located in proves machined directly into the cylinder.
Piston: The piston transfers impact power to the tool, generated by hydraulic power.
Front head assembly: This retains the tool, using the tool pins. By removing these pins, the tool can be changed.
Ring Bush: This guides the tool, Ring Bush limits the uppermost position of the tool. It is consumable parts, which should be checked for wear limits. If needed, they should be replaced.
Back head assembly: This contains the cushion chamber charged with N2 gas that is compressed during upward strokes of the piston, and serves to provide maximum absorption of the piston recoil, efficiently storing this energy for the next blow.
Through bolts: These are used to assemble the front head, the cylinder, and the back head. They have to be constantly tightened to the specified torque. Inspect the bolts for loosening, and re-tighten them weekly.
Q What are included in one set breaker?
A Standard package include two chisels, two hoses, one set of N2 charging kit with N2 bottle and pressure gauage, one set of spare seal kit, one tool box with necessary maintenance tools and operation manual as well.
Q Can the earth drill fit a variety of machines?
A Yes, as long as the machine specifications fall within the parameters of the Earth Drill as outlined in the product information.
Q What is the use of the auger?
A An auger is a rotating metal shaft with blades that circle the outside edge.
The blades are designed to clear away and pull out material from the hole you are digging.
The auger has many uses, which may include:
1.Fence Post Hole Drilling
3.Planting Trees 4.Deck Footings
Q How to operate the excavator auger?
A Here is a few tips for fitting the auger drive and auger to the mini excavator...
1.Lay the auger drive down with hose faces away from you.
2.Remove the bucket from the excavator if fitted.
3.Hook up the auger drive mount to excavator hitch and fit pin.
4.Connect up the hydraulics, have a rag handy to clean connections.
5.Connect the auger bit to the auger drive and fit pin 6.Use the toggle switch or foot pedal to control the auger.
Q What is an auger attachment for a skid steer?
A A skid steer auger is an attachment designed to pierce the ground and drill straight down. In doing so, this attachment proves useful in a wide range of applications.
Q How deep can you auger with a skid steer?
A Depth: Most auger drill bits have a dig depth of up to 72 inches. However, the actual dig depth depends on the model of skid steer you're using. Extension attachments are available to increase dig depth if necessary.
Q How much does an auger for a skid steer cost?
A It can range from $1500to $3000 per piece.
Q How deep can a towable auger dig?
A You can add an extension rod to the auger.
Q What is a hydraulic auger?
A A hydraulic auger is a powered drill that uses fluid pressure to operate. The hydraulic auger serves the same purpose as a drill machine but with much more power and speed. Some models can rotate up to 19 revolutions per minute!
Q Should you wet gravel before compacting?
A Should I wet gravel before compacting? You don't necessarily need to wet gravel before compacting, however a light amount of water can help to keep dust levels down. Just be sure not to make the area too wet.
Q How heavy of a plate compactor do I need?
A A rule of thumb is that a compactor will compact 1 inch of material for every 1,000 pounds of compaction force it exerts. You should also consider the machine's vibration frequency, measured in vibrations per minute. Higher vibration frequency (around 5,700 vpm) is good for compounding thin layers of material.
Q What is the difference between a rammer and a plate compactor?
A Rammers have the ability to compact a deeper amount of soil than a plate compactor, because the force from the plate is more direct. Therefore, more soil can be added to each layer which can make the process of filling and compacting a hole or trench, much faster.
Q Which is better jumping jack or plate compactor?
A Having Both. While vibrating plate compactors are best for larger areas and granular soils, jack rammers are an excellent choice for mixed or cohesive soil and smaller areas or trenches.
Q What are the four common types of compaction equipment?
A The method of compaction is primarily of four types such as kneading, static, dynamic or impact and vibratory compaction. Different type of action is effective in different type of soils such as for cohesive soils; sheepsfoot rollers or pneumatic rollers provide the kneading action.
