Everyone who drives a mini excavator knows that, in addition to the maintenance of the machine, the daily operating cost accounts for most of the cost. It is burning oil. Every time you refuel the machine, do you faint and feel heartache? Because it is inevitable to refuel, it is necessary to start from the throttling Oil (to some hard drives today) is working hard to provide you with fuel-saving tips for excavator operation. 1. When loading, the excavator should be in a higher position, and the truck should be parked at the same height as the work surface. The reason is simple, a stone, is it as hard as your head when you lift your knee? How much "energy" will it save ?Assuming the height is the same as before, you can increase the power by 40%. Cool! 2. When the bucket cylinder and the connecting rod, the ejector cylinder and the ejector are all at 90°, each cylinder pushes the excavator with the maximum force. 3. When excavating natural ground, the bucket or loosening device should keep the ground angle at about 30°, and then retract the bucket lever. When the bucket lever is close to vertical, the bucket lever has the maximum force and can withstand Larger loads. The two keys are like bending the arm to carry something, or keeping the arm straight, bent of course. 4. At the beginning of excavation, do not extend the bucket rod to the maximum function range, and the best function range is about 80%. 5. Bucket shaft excavation plan: The angle of the bucket shaft from the farthest 45° to the inside is 30°. The excavation depth is slightly different, but the larger stick and bucket should be operated within this plan, while the Do not use at the end of hydraulic cylinder stroke. 6. During continuous excavation, put the chassis forward so that you can walk immediately after excavation. If you want to walk, please change it again, you will burn a lot of oil at the beginning and end. 7. When digging the trench, first dig the two ends of the trench, and then dig the center part. In this way, excavating in the center can save a lot of work and energy. 8. Put the engine in the economic gear. Select auto idle to allow the engine to idle during excavation. 9, Minimize the radius of rotation. 10. The smaller the excavation depth, the better the excavation economy. It is divided into upper, middle and lower layers of excavation. Assuming that it is carried out in sequence from low to high, the function scale will first increase, and then decrease due to the increase in the power scale of the excavator, reducing the operating efficiency, which will cost a lot of oil.

Mini excavators are often used in special environments, such as embedding projects, pipe laying, trenching operations and so on. Excavators are not always used as a digging machine, builders sometimes use them to drive piles, and perhaps use them to lay pipelines. Therefore, you must pay special attention to the condition of the bucket to ensure that there are no problems with piling, crushing and walking equipment.   Another important part is the bucket cylinder coupling pin and bushing. It is necessary to check the tightness of these places in all directions. Many problems occur due to neglect of protection and inspection.   When you start the machine and move the bucket, stick, and rear arm, you may see the pins or cylinders move, but the stick and bucket don't. This is due to the looseness of the pin shaft and bushing.   Another key point is to carefully observe the connection between the rear arm and the excavator. If the joint under your rear arm wears too much, it may result in losing the value of the entire equipment.   In the specific use of mini excavators, the rubber tracks on mini excavators are different from the steel tracks on large machines, and they are suitable for grass and driveways. Many times you don't get to see the wear and tear of rubber tracks as closely as you look at steel tracks. As a result, you only see the wear of the rubber track, but not a lot of wear on the sprocket and supporting roller. In the end, you can estimate its use by checking the cracks on the rubber track and the wear of the edges, and pay attention to the height of the ribs, just like paying attention to the texture of the tire when looking at the wear of the tire.

Mini excavators, with their advantages of small size, strong power, low fuel consumption and high sensitivity, can carry out construction operations such as digging fertilizer ditches and fruit tree pits in the orchard. Power, but also save labor costs. At the same time, the multi-functional small excavator is also suitable for road greening repair, excavation of cable trenches, landfill pipelines, mining and mining, subway tunnels in narrow and congested spaces, suitable for coal washing plants, paper mills, sugar factories and other factories and mines. Picking and transporting, suitable for plowing and fermenting bedding operations in pig farms, chicken farms and other farms.   First, wide applicability. The mini excavator is small in size and flexible, and is very suitable for various pipeline excavation, foundation construction, public utilities and house repairs in towns and villages. The mini excavator's compact size and special design enable it to work in environments where large excavators cannot construct.   Second, versatility. The real benefit of a mini excavator is its versatility. Due to the relevant hydraulic power system, mini excavators can be equipped with many auxiliary working tools, such as equipped with rollers and plate compactors for landfill compaction of trenches; equipped with breakers and hydraulic tongs for lightweight lifting operations; equipped with rotary Drilling tools are used for drilling holes, fishing hooks are used for lifting heavy objects; equipment grippers are used for shoveling operations and so on.   Third, obvious job characteristics. The design and application of the tail turning radius is zero, so that the excavator operator does not need to consider whether there are obstacles on the construction site to prevent the excavator from rolling when the small excavator is working in an environment with limited working space, so that the operator can focus more on the bucket This also avoids damage to buildings around the construction site and the excavator itself. The most important feature of a mini excavator suitable for operations in narrow areas is its special boom and stick design. The boom of the mini excavator is articulated with the fuselage, which allows it to shake in a large range. This design enables the excavator to avoid obstacles when there are obstacles around without moving the fuselage frequently. At the same time, this also allows the excavator to facilitate excavation work around the wall or fence. The rubber track of the small excavator helps to reduce the damage to the phenomenon area and travel within the narrow construction range during the construction of the excavator.   Fourth, it is convenient to transport and move the workplace. Mini excavators are easy to transport between various construction sites, and do not need large trailers or heavy trucks for transport, and small transport items can carry them. This not only facilitates transportation, but also greatly reduces the transportation cost of the machine.
