Material Handling Troubleshooting Guides

Conveyors, cranes, hoists, and forklifts carry the rest of the plant. When they stop, the line stops within minutes. The good news: they almost always tell you they are about to fail. A belt that starts wandering. An idler that now makes a tick. A crane hook with a latch that will not spring back. Most of these are found on a walkaround if someone is walking.

Where conveyors go wrong

Belt issues are the top call. Mistracking, uneven wear, dust escape from a bad scraper. The fault is usually in the tail pulley, a bent idler, or a piece of material wedged under the belt. Walk the conveyor with the belt running. Your eyes catch things that sensors miss.

Belt wandering to one side: check pulley alignment first, idler alignment second.
Unusual vibration: one bad idler out of fifty is often enough to cause it. Feel each one with the back of your hand at slow speed.
Scraper blade worn: spillage piles up near the head pulley. Replace the blade on a schedule, not when you notice the pile.
Drive pulley lagging peeling off: you will hear it before you see it. Shutdown call.

Chains stretch, sprockets do not

Chain conveyors and chain hoists use chains that elongate under load. Once wear exceeds 3 percent of original pitch, the chain no longer engages the sprocket teeth cleanly. Measure a chain section with a gauge once a quarter, not by eye. Replacing a chain before it jumps is cheap. Replacing it after a load drops is not.

Cranes and hoists deserve a pre-shift look

Every shift-start inspection catches problems the PM missed. Brakes. Limit switches. Hook latch. Wire rope condition on any drum you can see. Do not skip this because you are busy. A failed upper limit switch on a hoist is a fatality waiting to happen.

Forklift damage is cumulative

Every small mast impact adds up. A forklift mast with visible channel damage is a future fall. Do not repair mast channels in-house. Heat treatment matters, and a field repair creates a hidden hazard the next operator will discover at the worst possible moment.

Shaft Alignment Fundamentals: Precision That Prevents Failure

Misalignment is the second leading cause of rotating equipment failure after lubrication problems. Laser alignment takes 30 minutes and prevents months of accelerated wear on bearings, seals, and couplings. This guide covers the basics of angular and offset misalignment correction.

Bearing Replacement: When, Why, and How to Do It Right

Bearings are the most commonly replaced component in industrial machinery. Yet 16% of premature bearing failures come from improper installation: wrong fit, contamination during mounting, or inadequate lubrication at startup. This guide covers the full process from selection to run-in.

What is Preventive Maintenance? Types, Benefits, and How to Start

Preventive maintenance replaces the 'run it until it breaks' approach with scheduled inspections and part replacements. Plants that run a solid PM program see 25-30% fewer emergency work orders within the first year. Here is how to build one that sticks.

Lubrication Best Practices: The Most Overlooked Maintenance Task

Poor lubrication causes up to 40% of bearing failures. Wrong grease, wrong amount, wrong interval, or contaminated supply are the usual culprits. Getting lubrication right is the single highest-ROI maintenance improvement most plants can make.
