Product Description:

We can design and produce excavator buckets for all brands, scientifically solve stress problem as different construction conditions and customer requirements, and have ability to ensure structural strength, use performance and product quality by selection of high-quality material, advanced computer-aided design and complete control over process welding quality. The specification ranges from 0.1m3 to 12m3.

By bucket type and material, there are common bucket, imitated original bucket, reinforced bucket and rock bucket, which are made from domestic high-tensile structural steel 16Mn (Q345B), in addition, the tooth plate and side edge board of reinforced bucket and rock bucket can be made from domestic high-quality wear-resistant steel NM360 and Sweden ultrahigh-strength wear-resistant steel HARDOX according to customer demands.

By function, there are ditching bucket, grid bucket, cleaning bucket, and tipping bucket, etc. The ditching bucket is suitable for ditching in different forms, and is featured by once forming, no finish and high work efficiency. The grid bucket is used to separate, excavate or salvage bulk materials excellently at a time, and is widely applicable to municipal administration, agriculture, forestry, water conservation and earthwork, and cleaning bucket and tipping bucket are suitable for finishing of slop and other planes and huge desilting and cleaning of riverway and ditches, and the tipping bucket can change the dip angle of cleaning bucket by the hydro-cylinder, which greatly improves work efficiency.

Q:How does the excavator cross the ground cable?
Slowly as before to walk down the wire frame in excavator digging machine below can go over to the other side in the same ibid.
Q:Modern 305-7 excavator oil consumption per hour, how many liters oil full load?
Diesel engine can be estimated by specific fuel consumption, but to know the normal work of the power consumption, if this is full load work, you can press the nameplate power, generally 180 grams / horsepower * hours, about 0.2 liters / horsepower * hours.
Q:How do you charge for excavator work?
To see how big is the 300 excavators, machine excavation is about 300 yuan an hour, the 220 is 260 yuan, 80 yuan, 115 is generally 160-200
Q:How much gas does the excavator use in a day?
An excavator consumes an average of 5 litres per hour
Q:Attentions of excavator operation
Three. Travel on soft groundExcavators in the swamp, flood and other soft ground work, should first use the bucket to try whether the ground can withstand the weight of excavators. If you forget the process, there may be serious consequences unless you are driving an amphibious excavator. Although the excavator is tracked design, contact the ground area is large, but the excavator into the mud, can not move events also occur! Just note that this can be avoided. In the swamp, flood and other soft ground work, to avoid excavators trapped, should pay attention to these: 1, first with the bucket test. 2, do not stay long in the same place. 3, go straight, turn less.Wetland excavatorIn case the excavator gets stuck in the mud, don't worry. Never try to climb out of a climbing system. That will only get you deeper and deeper. There are many ways to save. 1, if it's not deep enough, try to hollow out the two tracks. 2, if it is not, on the first try, how deep mud, if not very deep, directly to the front of the silt layer, for their own way, slowly toward the shore near the hard ground. 3, if it is infinitely deep silt, can rent a few piece of iron or board, sideways pressure to the track below, you can easily out.Four, vision blind areaThe driver's cab is on the left, the middle of the passive arm blocks the view, so there is a large blind spot on the right, especially in the rear of the right. Many excavator accidents are caused by falling or dying of the right side of the tail! So in the not very wide field work, try to let the excavator on the left, the right to set aside more space.Excavator rearview mirrorRearview mirror in the excavator is a very fragile things, often in work or transport in the touch off, many drivers will feel touched, it is not important, it is not in time to replace the new rear-view mirror. In fact, the rearview mirror is very important in excavators, especially on the right side. Accidents are often due to a lack of safety awareness!
Q:How much are the first pilot pressure and the two pilot pressure of the excavator?!
A pilot pressure is required with the normal operation of the system is generally about 35kg, two pilot pressure used in special conditions, such as the bucket bucket must use to dig out from the stone soil and the mining stress exceeds the system overflow pressure 345KG system set in a mining buried in the earth stone, then open the two pilot system, the sum of the overflow pressure at that time as one and two times the pilot pressure is 380kg, the working pressure increased to complete this action.
Q:What is the structure of the excavator?
Thoroughly inspect the surroundings and bottom of the locomotive in accordance with the following sequence: 1, whether there is oil, fuel and coolant leakage. 2, whether there are loose bolts and nuts?. 3 、 is there any broken wire, short circuit and loose joint of the battery in the electrical circuit?. 4, whether there is oil pollution?. 5, if there are rumors accumulation. Daily maintenance notice of daily inspection work is to ensure that the hydraulic excavator can be an important part in maintaining long-term efficient operation, especially for the self-employed, do the usual daily inspection work can reduce maintenance costs. First of all, around two laps to check the appearance of mechanical and mechanical chassis or unusual, and whether there is a rotary bearing oil flows out, and then check the braking device and bolt fastener track, tighten the screw, the change of the change in time, if you need to check the tire wheel excavator is whether there is abnormal, and pressure stability. Excavator bucket teeth to see whether there is greater wear, it is understood that the bucket teeth will greatly increase the wear and tear in the construction process of resistance, will seriously affect the work efficiency and increase the wear and tear of equipment parts. See if there is crack or oil leakage in the bucket and the cylinder. Check battery electrolyte to avoid below level line. The air filter is an important part of preventing dust from entering the excavator. It should be checked and cleaned frequently. Always check the fuel, lubricating oil, hydraulic oil, coolant, etc. whether to add or not, and choose the oil according to the requirements of the manual, and keep it clean. After starting check 1, whistle and all instruments are in good condition. 2, engine starting state, noise and exhaust color. 3 、 is there any leakage of oil, fuel and coolant?.
Q:What's the difference between a big excavator and a small excavator?
Operation is the same, big digging faster, higher technical requirements, and slowly practice.The big dig that large excavator is the weight (weight) between 40-200 tons, bucket capacity in 0.8-1.0 between the price of approximately between 80-100W, mainly used in various large-scale open-pit mining and large-scale infrastructure construction, land reclamation and harbour dredging project.A little digging small excavator, is the weight (weight) of less than 15 tons to 4-10 tons, the bucket volume in the 0.25-0.35 between the price of approximately between 34-48W, mainly used in highway maintenance, landscaping, residential construction, municipal engineering and construction projects in the field.
Q:What is the difference between a hydraulic excavator and a mechanical excavator?
Hydraulic excavators differ from mechanical excavators in specific driving forces. The hydraulic pressure depends on the hydraulic cylinder, the machine relies on the steel wire rope and the gear, the runner.Hydraulic excavator is a kind of multifunctional machine, is widely used in water conservancy engineering, transportation, power engineering and mining machinery in the construction, it is to reduce the heavy manual labor, ensure the quality of the project, plays ten important role to accelerate the construction speed and improve labor productivity.
Q:What are the specifications of excavators?
You didn't ask very clearly. A unit of length or weight, or what? The length is usually mm, and the unit of weight is usually kg. An imperial unit is usually inches in length and weighs t in weight
