Wheel Station Change-Out

Wheel Station Change-Out

At BCMEL, the 785 wheel station change-out involves detailed maintenance, including removing and replacing components in Caterpillar's 785 truck wheel assembly. Tasks include tire removal, rim and hub inspection, and replacement of worn or damaged parts. Specialized tools, equipment, and expertise are needed to maintain the truck's performance and safety.

Key Features

Supporting the weight
The main role of the wheel station is to bear the weight of the dump truck, along with its cargo. This necessitates robust construction and materials that can endure substantial loads
Providing traction
The wheels and tires of the dump truck provide traction, allowing the vehicle to move efficiently on different terrains, such as rough, muddy, or uneven surfaces often encountered in mining and construction sites
Steering
The wheel station enables the dump truck to be steered, allowing for precise maneuvering and positioning of the vehicle, especially when loading or unloading materials.
Suspension
The wheel station typically incorporates a suspension system to absorb shocks and vibrations encountered during operation, improving driver comfort and reducing wear and tear on the vehicle.
Braking
The wheel station includes braking components such as brake calipers, discs, and pads, which are crucial for stopping the vehicle safely, particularly when carrying heavy loads downhill or on slippery surfaces.
Power transmission
In some dump trucks, especially those with all-wheel drive or articulated designs, the wheel station may also be responsible for transmitting power from the engine and transmission to the wheels, providing the necessary torque for propulsion.
Monitoring and control
Modern dump trucks may incorporate sensors and monitoring systems in the wheel station to track parameters such as tire pressure, temperature, and condition, allowing for proactive maintenance and ensuring optimal performance and safety.

The advantages of a 785C wheel station change-out

Regularly replacing worn tires and components helps maintain optimal traction and stability, reducing the risk of accidents and enhancing overall safety.

Installing new tires and components ensures proper alignment and balance, leading to smoother operation and better handling of the off-highway truck

By replacing tires and components before they become excessively worn or damaged, the overall lifespan of the vehicle is extended, reducing downtime and maintenance costs.

A well-maintained wheel station contributes to the truck’s overall reliability and uptime, allowing it to operate more efficiently and effectively in demanding work environments.

Performing wheel station change-outs as part of routine maintenance schedules helps ensure that the truck remains in compliance with manufacturer recommendations, maximizing performance and longevity.

steps involved in a 785 wheel station change-out typically include

Secure the truck in a safe and stable position, and gather all necessary tools and equipment.

Remove the old tire from the wheel hub assembly using appropriate lifting and handling equipment.

Inspect the wheel hub, rim, and other components for signs of wear, damage, or defects.

Install the new tire onto the wheel hub assembly, ensuring proper alignment and torque specifications.

Balance the newly installed tire to minimize vibration and ensure smooth operation.

Mount the wheel assembly back onto the truck’s axle, ensuring proper alignment and tightening of bolts.

Conduct a test run to verify the proper functioning of the wheel assembly and ensure there are no issues or abnormalities

Record the details of the wheel station change-out, including the date, mileage, and any relevant observations or recommendations for future maintenance

Clean up the work area and properly dispose of any old or damaged components.

Perform a final inspection of the wheel assembly to ensure everything is installed correctly and meets safety standards.
