The new Manufactured Canoe Liner from Martin Engineering is made from durable urethane moulded around a rugged steel plate to absorb impact and abrasion from the punishing bulk handling environment. With the protective plate integrated directly into the urethane liner, the design delivers superior shielding of the skirt sealing system and chute wall from heavy, fast-moving cargo. The result is extended equipment life, longer periods of dust and spillage control, improved safety and less maintenance, reducing the overall cost of operation.
Previously, most wear liners were sheets of steel welded onto the internal chute wall of the conveyor loading zone. These protected the wall from the punishing effects of splashing, shifting and abrasive material. But since they are wear parts, periodic replacement of these early designs involved enclosed chute entry and hot work using a blow torch, which required certification and supervision, while running the risk of igniting explosive dust. The steel plates generally did not effectively protect the rubber skirt seal, leading to more frequent skirt replacements. Moreover, the wear liner’s position often left a gap between the liner and the skirting, which captured small lumps of material that could damage the belt. These design issues resulted in excessive downtime and premature equipment replacement.
The Manufactured Canoe Liner is an engineered urethane strip moulded directly around a protective steel plate. This avoids the bonding issues common to previous designs, preventing urethane separation from the plate that could damage the belt and enclosure.
Each section has a series of 2in long bracket holes for vertical adjustment. The bottom “belt side” of the liner is cut to an optional 20º, 35º, or 45º angle to maximise belt sealing and protect the softer material of the skirt seal from premature wear.
As material gradually erodes the Manufactured Canoe Liner, the bottom trough angle continues to protect the skirting. If there are significant gaps between the belt and liner, each cartridge can be adjusted by a single technician using a socket wrench.
