Uneven compaction due to damaged plates reduces hauling efficiency and can lead to material spillage during transport.

Truck Bed Lining Maintenance

The bed lining serves as a protective barrier between the truck’s structural bed and the abrasive materials being processed. It prevents costly damage from sharp concrete fragments, rebar, and rocks.

• Clean the bed lining after each use to remove trapped debris, dust, and moisture that can accelerate wear
• Inspect the lining weekly for cracks, tears, delamination, or areas where it has pulled away from the bed
• Check fasteners (if bolted) or adhesive seals (if glued) for integrity and re-secure as needed
• Repair minor damage promptly using approved patching kits to prevent further degradation
• Replace the lining when wear compromises its protective function—typically when more than 10–15% of the surface is damaged

High-quality polyurethane or rubber linings offer superior impact resistance and longevity compared to basic steel beds.

Belt Tension and Drive System Checks

The crusher’s fan and hydraulic pump are typically driven by belts connected to the engine via pulley systems. Proper belt tension is critical for efficient power transfer and component longevity.

• Inspect belts weekly for signs of cracking, fraying, glazing, or separation
• Check belt tension using a tension gauge or the "thumb pressure" method—belts should deflect about 1/2 inch when pressed midway between pulleys
• Adjust tension according to manufacturer specifications—over-tightening can damage bearings, while loose belts slip and overheat
• Ensure pulleys are aligned properly to prevent premature belt wear
• Replace belts in sets if multiple belts are used to maintain even load distribution
• Listen for squealing or chirping noises, which often indicate improper tension or worn belts

Expert Tip: Mark belts with chalk upon installation to monitor slippage and track wear patterns over time.

Lubrication of Moving Components (Greasing Gears and Joints)

Regular lubrication minimizes friction, reduces wear, and prevents seizing of critical moving parts such as pivot points, gears, and linkages.

• Grease all zerks (grease fittings) daily or after every 8–10 hours of operation
• Use high-quality, heavy-duty lithium-based or extreme pressure (EP) grease suitable for construction equipment
• Focus on high-wear areas: compactor hinge points, hydraulic cylinder pins, linkage joints, and gear housings
• Apply grease until fresh lubricant appears at the seals—this ensures old, contaminated grease is pushed out
• Wipe away excess grease to prevent dirt accumulation, which can act as an abrasive
• Inspect seals and boots during greasing to ensure they are intact and not allowing contamination

Under-lubrication leads to accelerated wear, while over-greasing can cause seal damage and overheating.
