Chelker have worked with BHL on a number of special projects including submerged effluent conveyors, roof tile handling conveyors, and a magnetic conveyor for food can handling.

The tile handling conveyor project required design for an aggressive environment including heat, abrasive dust and weak acid spray. The equipment had to be designed to fit into an existing production line, requiring on-site measurements to be taken out-of-hours, and consideration being given to rapid installation between production shifts.
