The competition in the 7-ton small excavation market is fierce. Is it domestic or imported for users? In fact, the domestic 7-ton small excavation has become more and more mature, similar to Sany sy75c, XCMG xe75d, Liugong 9075e and other representative models. Today, let's talk about XCMG xe75d excavator. What are the advantages and disadvantages in the use process?
Xe75d excavator is a 7-ton product mainly produced by XCMG, with a total working weight of 7.46 tons and a standard bucket volume of 0.3m?, which is one of the popular small excavation products at present.
The boom of XCMG xe75d is partially strengthened, and the stick is made up of the molded "U-shaped plate" and the upper cover plate by welding, which has a longer service life; X-frame chassis structure is adopted, and the inner part of the lower frame is formed into a large section box through the stiffener plate, which has a good bearing performance.
Dynamic aspect
XCMG xe75d excavator is equipped with jiubaotian small displacement turbocharged engine. The engine maintenance points are arranged on one side. The engine has low noise and vibration, good fuel economy, strong power, and sufficient low-speed torque reserve.
When the throttle is in the fourth gear or above and the control handle is neutral for more than 4S, the engine will automatically reduce the engine speed, reduce unnecessary fuel consumption, and reduce noise and exhaust emissions. When the handle acts again, the engine speed will resume.
XCMG xe75d excavator adopts a new generation of load sensitive hydraulic system, with less system pressure loss. The output flow of constant power variable piston pump is always suitable for the opening of multi-channel valve core, without redundant flow loss, to achieve load independent flow distribution, better flexibility of composite action, and smoother flat action.

Listen to boss Xu Gong.
1. Boss Wang: great strength
"I've been driving the new car since I came back. I usually work on the construction site. I don't have a lot of loose work. The old model doesn't have a very coordinated action, but the new one is good. The action is coordinated and the strength is not small. The fuel consumption of the air conditioner is about 30 yuan. The diesel oil is 5.5/l. The cab space is large enough. It's very comfortable to sit inside and easy to operate. I feel it after getting off 8-9 hours a day. Not very tired. "
2. Boss Hu: save fuel!
Advantages: fuel saving, 5.5 oil 5 throttle 22, turn on air conditioner 23! Small arm speed block, stable car, full bucket of mud loading to the farthest point without raising the bottom; large cab space, curtains everywhere, good air conditioning effect at present, good storage space near the cab door, with butter gun rack, winter engine cooling air and butter gun is much easier to hit, walking rabbits running on the ground.
Disadvantages: the bucket volume is too small, the body is so aggressive, it's not particularly harmonious to match a 0.3 bucket, the body steel is not good, the bucket is not wear-resistant, the paint on the body is not good, there are traces, some edges and corners are warped, the three parts are made in China, everywhere, I don't know how about the future.
3. Boss Guo: the air conditioning is not very good
Advantages: compared with Liugong's 908c at home and his friend's 908d, the action coordination is much better than Liugong's. the engine is jiubaotian's fuel saving. Compared with Liugong's Cummins B3.3 power, the same seven accelerators save one liter of oil an hour. It's about 35 yuan an hour for us to hit seven more gas pedals at 6 yuan. The speed is very fast, but the strength is a little bit small. After all, the engine is only 42 kilowatts.
Disadvantages: the air conditioning effect is not very good. The air conditioning panel is relatively simple. There are only two knobs, one for refrigeration and heating conversion, and the other for air volume knob with three gears. The second hydraulic components are quite domestic. The rotating motor is Shanghai nanbosk, so is the walking estimation.
