1, What are the standards for replacing worn tires on electric forklifts
Electric forklifts are electric powered industrial handling vehicles commonly used in factory workshops, warehouses, distribution centers, and other places. The tires used by electric forklifts need to be regularly inspected and replaced to avoid affecting the safe operation of electric forklifts. The general standard for tire replacement of electric forklifts is:
1. The normal service life of electric forklift tires is 4-5 years. If 5 years have passed, even if the tire tread wear is minimal, it still needs to be replaced.
2. When the groove depth left on the tread of the electric forklift tire is less than 1.6 millimeters, it needs to be replaced.
3. Electric forklift tires need to be replaced after three or more repairs to reduce the risk of tire blowouts.
2, Steps for replacing tires on electric forklifts
During the use of electric forklifts, if there are tire cracking, damage, uneven wear, excessive wear, etc., it is necessary to replace the tires in a timely manner. Tires that have been used for a certain period of time also need to be replaced. The specific replacement method steps are as follows:
1. Remove the load from the forklift, park the electric forklift on a flat and solid road surface, lower the forks to the ground, and apply the parking brake to stop the wheels.
2. Use a jack to lift the electric forklift under the outer door frame on the side where the tire needs to be replaced, until the tire is still slightly in contact with the ground, and place a cushion block under the front side of the forklift frame to prevent it from falling.
3. Loosen the wheel hub nut with a wheel hub nut wrench or other tool until the nut can be turned by hand, but be careful to loosen the nut in a diagonal order.
4. Lift the electric forklift up a little further until the tires are slightly off the ground, remove the wheel hub nuts, and disassemble the front wheel assembly.
5. Place the side of the wheel hub of the front wheel assembly on a flat and hard road surface. At this time, a cushion such as a wooden board or blanket should be laid on the road surface to prevent the wheel hub from rubbing. With the help of a tool, press down on the tire, remove the two half piece snap springs, then remove the retaining ring, and finally remove the tire.
6. Put the new tires of the electric forklift into the wheel rim, press down the tires, place the retaining ring, insert the snap spring, and release the tires to directly assemble the front wheel assembly.
7. Insert the assembled front wheel assembly into the wheel hub bolts, first tighten the wheel hub nuts one by one by hand, and then use a wheel hub nut wrench or other tool to pre tighten the wheel hub nuts diagonally, with a pre tightening torque of about 20 to 30 Nm. However, it is important to note that the threads of the bolts and nuts must not be stained with grease or oil, otherwise it will affect the tightening torque of the nuts and cause accidental safety accidents.
8. Remove the cushion block from under the electric forklift frame, lower the forklift and tighten the wheel hub nuts diagonally with the specified tightening torque.
Reminder: When conducting a test run after replacing the tire, be sure to check if the wheel hub nut is loose. If it is loose, tighten it to avoid affecting normal use in the future
3, Is it better for electric forklift tires to be solid or inflated
Whether solid or inflatable tires are better for electric forklifts depends on the working environment of the electric forklift
If the workplace is chaotic, such as places with a lot of stones, iron filings, and waste residue, it is recommended to use solid tires to avoid tire blowouts. If the workplace is clean and tidy, it is recommended to use pneumatic tires, which have better anti slip performance and are more economical.
