Loader is an indispensable “Hercules” on the construction site, whether it is carrying materials or clean up the site, it can easily deal with. But just like people occasionally get sick, the loader will inevitably have some minor problems after a long time of use. Today, we will talk about the common faults of the loader, see how they occur, what performance, and how to quickly solve, so that you can easily deal with the work of the small trouble.
The loader common faults and cause analysis
1. Difficulty or inability to start the engine
Reason:
Insufficient battery power or aging battery
Fuel system blockage or poor fuel quality
Failure of starter motor or ignition system
Air filter clogged, resulting in insufficient air intake
Phenomenon:
Engine does not respond or starts slowly when starting
Stalls immediately after starting
Solution:
Check the battery voltage, charge or replace if necessary
Clean the fuel system and replace with high quality fuel
Check starter motor and ignition system, repair or replace damaged parts
Clean or replace air filter
2. Insufficient hydraulic system pressure
Cause:
Insufficient or poor quality hydraulic fluid
Worn hydraulic pump or damaged seals
Hydraulic line blockage or leakage
Phenomenon:
Loader lifting powerless or slow movement
Hydraulic system noise abnormality
Solution:
Check the hydraulic oil level, replenish or replace the hydraulic oil
Inspection and repair of the hydraulic pump, replace worn parts
Check the hydraulic pipeline, repair the leakage or clogging
3. Abnormal tire wear
Cause:
Tire pressure too high or too low
Improper driving maneuvers, such as sharp turns or hard braking
Poor ground conditions, such as gravel or sharp objects
Phenomenon:
Uneven wear on the tire surface
Cracks or bulges on the side of the tire
Solution:
Regularly check tire pressure and keep it within the standard range
Standardize driving operations, avoid sharp turns or harsh braking
Slow down under adverse road conditions and install tire protection chains if necessary.
4. Braking system failure
Cause:
Insufficient or deteriorated brake fluid
Brake pads are worn out
Leakage of air or oil from brake lines
Phenomenon:
Slow response or complete failure when braking
Brake pedal feels soft when pressed
Solution:
Check brake fluid, replenish or replace
Replace worn brake pads
Check brake lines and fix leaks
5. Transmission rattles or shifts with difficulty
Cause:
Insufficient or poor quality transmission fluid
Worn gears or damaged synchronizers
Loose or damaged gearshift mechanism
Phenomenon:
Rattling or sticking when shifting gears
Abnormally high transmission temperature
Solution:
Check the transmission fluid, replenish or replace
Inspect the inside of the gearbox, replace worn parts
Inspect the gearshift mechanism, repair or replace damaged partsSecond, how to prevent loader failure?
Regular maintenance:
According to the maintenance cycle recommended by the manufacturer, change the oil, hydraulic oil, filters and other wearing parts regularly to ensure that the equipment is in the best condition.
Standardized operation:
Avoid overloaded operation, reduce rapid acceleration, emergency braking and other improper operation, to extend the service life of the equipment.
Daily inspection:
Check the tire pressure, oil level, braking system and other key parts before each use to find and solve problems in time.
Environmental adaptation:
According to the operating environment to choose the appropriate equipment configuration, such as the use of reinforced tires or protective devices in poor road conditions.
If you encounter other problems in the process of use, it is recommended to contact professional maintenance personnel in a timely manner to ensure the safe and efficient operation of the equipment.
