Un underground mining wheel mucking loader is widely used for ore handling in tunnels and mines. During daily work, it may face various faults. Proper maintenance is essential to extend its service life and ensure safe, efficient operation. Below are several common maintenance methods and tips.

1. Removing the Tire from the Rim

One common issue with an underground mining wheel mucking loader is separating the tire from the rim. Long-term use without disassembly often causes rust, making them stick tightly. Deflating the tire and rolling it is not effective. Instead, add water as lubrication between the tire and rim. Then, press both sides with two bulldozer shovels, insert an iron rod across the rim, and use a steel rope with a crane or loader to lift it. This method separates the tire and rim easily.

2. Problems with Incomplete Wrenches

Sometimes, incomplete wrenches cause difficulties in disassembly and assembly. In this case, you can insert copper, iron wire, or a screwdriver inside or outside the wrench to increase grip. If the open-end wrench is smaller than the bolt head or a hex wrench is larger, carefully file the wrench to adjust the size.

3. Replacing Worn Bushings on Pins

On wheel mucking loaders, the bushings of the pins may wear out due to long-term use and poor lubrication. If not replaced correctly, the new bushing may become damaged or misaligned. A reliable method is to first place the bushing on the pin, insert it into the seat hole for positioning, and then gently hammer the pin. This ensures the bushing is pressed into place without damage.

4. Handling Damaged Connecting Rod Bearings

Connecting rod bearings on an underground mining wheel mucking loader often get damaged. To remove the bearing, place the rod in a vise. Use a socket slightly smaller than the outer bearing ring on one side and a larger socket on the other side. Gradually tighten the vise until the bearing presses out. If available, gas cutting tools can also be used to cut the outer bearing ring directly.

Un underground mining wheel mucking loader requires daily care to reduce failures and downtime. Regular lubrication, proper disassembly techniques, and timely replacement of worn parts ensure stable performance. With consistent maintenance, the mucking loader will work more efficiently and have a longer service life.
