How to properly maintain the crawler crane to prolong its service life!

When we complain about the frequent failure of equipment, have we considered the correct and timely maintenance, adjustment and maintenance of equipment in the process of using equipment? What are the main points for maintenance of crawler cranes?

First of all, the four plates of the track we hang on routine maintenance as we explain one by one: the whole car steel structure anticorrosion crawler crane steel structure is the entire crane steel structure skeleton, if rust, so not only affects the appearance, is more likely to occur because the structure corrosion and cause accidents. Therefore, in the discovery of paint, bruising and other conditions should be timely supplementation of paint. All vehicle activities hinge point and bearing timely lubrication and maintenance points include: Boom hinge pin, track plate connection pin, pulley block bearing, track belt supporting wheel, track support wheel and other parts of lubrication.

Engine maintenance

1. before the use of a caterpillar crane, the oil and oil amount and water level of the engine should be used in time. If there is a lack of comparison, it should be added in time.

2. the oil level of diesel should also be checked in front of the car to avoid the oil pump entering the air after the use of the oil.

3. the oil, fuel and coolant should be replaced ahead of time in the northern season. In summer, the oil of low viscosity should be used to turn the winter oil. The oil is used in winter diesel oil and the coolant is selected according to the average winter temperature of the local years.

4. when the operation of the engine reaches the number of hours of the instructions, or after observation, it is found that the oil of the same grade should be replaced after the oil oil is deteriorated.

Maintenance of hydraulic system

1. the hydraulic system should choose T32 or the same grade of hydraulic oil in winter, and remove the water from the oil-water separator in time to avoid the freezing burst oil.

2., the hydraulic oil grid should be replaced according to the requirement of the crane operation instructions. After the daily check and found that the hydraulic oil grid is dirty, though the time limit for maintenance and replacement is not reached, it is also necessary to replace the hydraulic oil grid.

3. under conditions of conditions, a hydraulic system is often filtered and cleaned. Above we have shared how to maintain the key points of crawler cranes. Now we introduce the contents of daily maintenance, monthly maintenance and annual maintenance for crawler cranes.

Routine examination

1, check whether the engine oil is missing

2, check whether the cooling fluid of the water tank is missing

3, check whether the hydraulic oil and diesel oil are missing

4, check whether the four round is loose, worn, deformed, or crack

5. Check the wear, deformation, or crack of the pulley and bearing of the various ministries

6. Check whether the wire rope is broken, deformed and worn seriously.

7, check whether each arm frame, A frame is deformed and open welding

8. Check the lock of the connecting pin and rope, whether the pin is damaged or missing

9. Check whether the hook is slippage

10, check whether the bolts are loose and shedding

11. Check whether the control devices are normal

12. Check whether the safety devices are normal

13. Check whether the electrical devices are normal or not

14. Check the normal monthly maintenance and maintenance of each instrument and indicator lamp

Diesel engine：

1, check whether the oil filter core is blocked (300 hours must be replaced)

2, check whether the fuel filter cartridge is blocked (300 hours must be replaced)

3. Whether the oil-water separator is blocked or not to be drained every day (must be replaced)

4, whether the water tank coolant is enough to add enough

5. Whether the filter cartridge is blocked, the filter core is cleaned or replaced.

6, the liquid quantity and proportion of the battery is normal, the terminal is loose, and the corrosion is corroded

Walking device:

1. Whether the driving wheel, the guide wheel, the support wheel, and the tug are loose or leaking

2. Whether the crawler plate is worn out, deformation or crack

3. Whether the caterpillar frame is collided or deformed

4. Whether the walking reducer, motor and so on are working normally, whether the hydraulic pipe is damaged or leaking

Host part:

1. Whether the platform is messy and bad, whether there is a crack in the open welding

2. Whether fuel oil and hydraulic oil level meet the requirements

3. Whether the bolt is loose and the wire rope breaks the broken wire

4, the work of the brake and the clutch is normal

5. Whether the rotary support is injected with oil and the fixed bolt is loose

6. Whether the oil leakage work is normal in every reducer, motor, valve group and pipeline

Operating equipment:

1. Whether the connection of the base arm frame and each arm frame is safe and reliable

2. The safety and reliability of the shedding device for the steel wire rope of each pulley group and the hoisting hook

3, A type, anti leaning rod, support frame and so on is safe and reliable

4, above the requirements of open welding are not used, the professional must be repaired or replaced.

Safety device:

1. The indicator lights in the driver's room are shown to be normal.

2. Whether the monitor and monitor are normal

3. Whether the hydraulic control system is normal

4. Whether each safety limit device is normal

5. Whether the distribution lines are loose, short circuited and serious aging

6. Whether the angle meter is accurate or not

Annual inspection, maintenance and maintenance

1, the replacement of the engine filter

2, the replacement of hydraulic system filter

3. Replacing the filter core of the air filter

4. Replacement of hydraulic oil

5. Change the gear oil of each reducer

6. Clean the appearance of various hydraulic components and find out or replace problems in time.

7. Check the rust and wear of the wire rope and the rope.

8. Whether the hydraulic lines and electric lines are damaged or not, the problem must be replaced.

9. Check the performance to meet the technical requirements

10, the above inspection should be replaced if the relevant performance parameters and technical requirements must be replaced.
