- Q:What are the units of measurement for loaders?
- The general materials such as coal by tonnage as engineering cases such as soil, sand is cubic calculation
- Q:What does the ZL50 loader tire model '23.5-25' represent?
- What does the tire model 23.5-25 stand for?23.5 represents the top of the tire by 23.5 inches25 represents a tire with a 25 inch diameter rimNo. for low pressure tyres
- Q:Why are loaders charging 24?
- Mainly depends on the power to start the motor, if the use of 12V power as the starting motor power, the current will be doubled, and related wires will be thicker and increase costs.
- 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:Customs HS code for imported loader tires
- The key depends on the car. The new inflatable rubber tires are classified as 4011, the refurbished ones are classified as 4012, and the inner tubes are classified as 4013.You should have this herringbone similar to the tread bar, recommendation 40116200 (wheel not more than 61 cm), or 40116300 (wheel over 61 cm).
- Q:Loader operation detailed method
- 7, prohibit manipulation in the direction of the inclined ladder, if necessary, should be adjusted in the open inclined ladder, open up.8,After loading, block the loader's tires with a wedge and secure the machine with ropes.When loading must not come to car, stepping on the brake throttle arm unless in neutral, should go to the front when the throttle, speed is slow but also a touch on the brakes arm backhoe unloading, a long time to master.
- Q:Loader maintenanceThe ammeter in the loader is light, please ask the reason
- Maintenance is to play butter, check whether the instrument is normal, to see whether the body has oil leakage, check the oil brake oil enough
- Q:What are the transmission systems of the loader?
- 1. what are the components of the transmission system of the wheel loader? Its function and working principle are briefly described.The power line is the engine, hydraulic torque converter, transmission, front and rear drive axle, wheel side reducer, wheel.Hydraulic torque converter, loader adopts double turbo torque converter, can change its working condition automatically according to the change of external load. It is equivalent to a two gear automatic transmission, which improves the external load adaptability of loader.
- Q:How long will it take to change the hydraulic transmission oil for the loader?
- The new 300 hours change, then every 2000 for 8 oil, heavy work, then a little shorter time
- 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.
