Features— Changlin Road Roller 8272-5
The road roller coming in the model of 8272-5 is a kind of pneumatic roller. It adopts eleven-wheel vibration, which brings high compacting quality. It is equipped with two sets of sprinkling system. By adjusting the capacity of ballast water, the ground pressure can be changed correspondingly.
Due to these advantages, the road roller has found applications in compaction of cohesive or non-cohesive base and sub-base layers of various materials. For example, it can be used to compact asphalt in the construction of roads.

- Q:What is the lifting time of the loader? What does the three item mean?
- The three term refers to the time when the loader has a complete loading and unloading time, from lifting, loading and unloading, and landing. Different models also use different time, most loaders in more than 9 seconds, 10 seconds or so.
- Q:What brand of loader tires are good?
- Loaders, tire brands, large and small, is too much. General Chaoyang, forward, wind, and so on may be more famous, I heard, relatively speaking, relatively high prices, after all, is the big brand, the market price is relatively transparent. In fact, people do not think big brands of tires is a good person, previously used a Baoyi loader tire completely have not heard of the brand because it took the same price of 20 layers and 16 layers of Aeolus I try holding the attitude to buy two for two or three months is not what the problem
- Q:The working principle of the loader engine
- The working principle of two stroke diesel engineBy two strokes of the piston to complete a working cycle of the engine is called the two stroke diesel engine, oil engine crankshaft in a work cycle of only one round, compared with the four stroke diesel engine, it improves the work ability, there are great differences in the structure and working principle.The basic structure of the two stroke diesel engine is the same as that of the four stroke diesel engine, and the main difference is in the valve train. Two redThe diesel engine has no air intake valve, and some do not have an exhaust valve. Instead, a scavenging port and an exhaust port are arranged at the lower part of the cylinder;A scavenging port and an exhaust valve mechanism are also provided. Specially set up a scavenging pump driven by moving parts and stored pressure airThe utility model simplifies the structure of the diesel engine by matching the piston and the air port to complete the gas distribution.The diagram is the working principle diagram of the two stroke diesel engine. The scavenging pump is attached to one side of the diesel engineThe rotor is driven by a diesel engine. Air is inhaled from the pump, compressed and discharged, stored in a larger volumeScavenge the air box and maintain a certain amount of pressure in it. The work of the two stroke diesel engine is illustrated in this paperPrinciple.
- Q:What function does the air compressor of the loader have? What is the principle?
- The principle of braking: after compressing the air, there is a certain air pressure, there is power to drive a series of cylinders and so on.
- Q:The role of Loaders
- More, can the earthwork and stonework, coal, slag, coal, ore, general construction waste loading and so on. 1, the general cargo yard loading 2, leveling the site 3, inverted side operations. 4, do traction in special circumstances. Hope to be of some help to you
- Q:Construction machinery, such as excavators, loaders and so on, belong to special equipment?
- No, just like if you drive a car on the road, it is necessary to have a driver's license, usually issued authority to manage, you can log on the Quality Supervision Bureau website to see, or askJob description of special equipment departmentJob responsibility of special equipment division of quality supervision bureau:1 、 special equipment safety supervision;2, special equipment operators assessment, certification3. Registration of special equipment.
- Q:What does the triplex valve on the loader mean?
- There are multiple working devicesA normal forklift is an armA bucketIf the 3 piece, such as adding a bucket, lateral displacementOr grab one of the joystick more than one
- Q:How to save energy and reduce the cost of loader?
- Forklift at 70-80 is the most efficient choice of the nearest route forklift not idle for more than 10 clocks will be off without running road speed usually less air conditioning air check vehicle engine oil dry air filter regularly observed whether to ensure complete combustion of clean diesel leaking prohibitedDisposable rubbing material
- Q:There's a stereo in front of the loader, but why not?
- 1, loaders and forklifts are the same kind of machine, no different.2, the loader is a widely used in highway, railway, construction, utilities, ports, mines and other construction projects of earthwork construction machinery, which is mainly used to shovel of soil, sand, lime, coal and other bulk materials, can also be used as a mild shovel of ore and hard soil digging etc..
- Q:Liugong ZL50CN loader, how much do you buy?
- We have more than 320 thousand points to buy a dozen of the basic stage to spend 2 million bucks.
