Q:50 what is the hourly fuel consumption of the loader?
In highway construction, it is mainly used for filling and digging of subgrade engineering, aggregate and loading of asphalt and cement concrete field. Because of its advantages of fast operation, good maneuverability and easy operation, it has developed rapidly and become the main machinery in the construction of earthwork.
Q:How big is the bucket capacity of model 50 tire loaders?
There are 3 sides with 2.7 sides, Liugong 50 seems to be 2.7
Q:What is the difference between a loader dry bridge and a wet bridge?
Dry and wet for the brake on the bridge for the dry bridge using caliper disc brake, brake and brake disc exposed; wet brake pads on the bridge bridge closed shell, immersed in gear oil, by oil circulation cooling. Compared with the dry brake, the utility model is easy to be polluted and worn by the material, and the wet brake can be free from maintenance because of the full closure. At present, most domestic loaders adopt dry bridges, and wet bridges are used in export models and foreign brands, and the wet bridges are also the direction of technological development.
Q:How about the quality of Xinbang loader zl926
Xinbang is doing the first, but not now, whether from the technical or from the quality or appearance from other manufacturers and is too large and can not be compared, but Mingyu car is good, can be regarded as the bright younger generation.
Q:Who knows the quality of the loaders in Shandong? 16?
To tell you the Laizhou loader bill of goods. I do you a few years what all understand. In any case, Levin is also the country's largest manufacturer of small loaders, starting early
Q:Loader shovel skills
A lightWhen loading the loader, place the heel firmly against the floor of the cab, parallel the pedals and the accelerator pedal, and gently press the refueling pedal.Two.The loader always keeps the throttle steady during the operation. General operating conditions, the throttle opening at about 70% is appropriate.From threeIn the loader operation, the baseboard should be separated from the brake pedal, flat on the cab floor, and never step on the brake pedal. Loaders often work on uneven job sites. If the foot is always on the brake pedal, the body is running up and down, causing the driver to step on the brake pedal without interest. In general, control the engine conditions and shift gears by controlling the speed of the throttle. This will avoid frequent braking, resulting in overheating of the braking system, but also for the loader to speed up quickly to bring convenience.Four QinIn loader operation, especially in the operation of digging and digging, the bucket should be filled with material under the condition of stable throttle. The cycle pull of the hoisting and turning control lever is called "diligence"". This process is very important and has a great impact on fuel consumption.Five coordinationCoordination is the combination of lifting and bucket handling. Generally, the backhoe process of the loader is to lay the bucket flat on the ground and smoothly to the material pile. When the bucket is parallel to the hopper, the resistance should first follow the principle of first lifting the arm and then receiving the bucket. It can effectively avoid the bucket bottom resistance, which can give full play to the maximum breakout force.Six strictly prohibitedFirst of all, tires are strictly prohibited. When the loader is working, the door will skid when encountering resistance. This phenomenon is usually caused by improper handling by drivers, increasing fuel consumption and damaging the tires.
Q:What are the commonly used models of loader for Liuzhou 50?
3100mm maximum discharge height; corresponding discharge distance 1130mm; the operation quality of 15850kg 162kw; rated power; fuel consumption per hour 75 yuan per hour speed; 40km; bucket capacity of 2.7~3.0 cubic 5000kg; rated load; the maximum breakout force not less than 155kN.
Q:What's the price of the concrete loader mixer machine? How much is it?
In the first heavy industry is still OK, you yourself Baidu check
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:936 how much is the loader?
The forklift and loader are synonymous and have been merged. Loader Name: Loader: definition: use the bucket at the front of the body to shovel, install, transport, unloading operations of construction machinery. The loader is a kind of earthwork construction machine which is widely used in highway, railway, building, hydropower, port, mine and other construction projects,
