Second Hand Conveyors – Pitfalls

Second Hand Conveyors can seem a cost-effective way to procure plant equipment rather than investing in new chain, roller or belt conveyors. Unless due-diligence is undertaken, the perceived bargain can often lead to a costly refurbishment if fundamental mechanical/electrical checks are not adopted. Sometimes plant and machinery such as conveyor systems can have the maintenance budgets removed a long time before the equipment is de-commissioned, leaving the new owner with a fully depreciated and well worn investment. Some basic pre-purchase checks would include: Conveyor components, conveyor idlers and rollers should be checked for worn shafts, tubes and bearings for signs of fatigue. Drive chains, chain wear strips and belting should be checked for excessive wear. The power-train and gear-motor assembly should be appropriate for the conveyor capacity. Check that the duty, torque and output speed are suitable to the new work area. Conveyor stringers and the frame integrity should be inspected for wear. Damaged, buckled or corroded frames can result in belt/chain misalignment, material spillage or safety issues. Safety guarding and devices should be intact and operative. All pulleys, chains and rollers should have guarding applicable to Australian standards requirements AS 1755-2000.
