, a leading global company in bulk material handling technology, has introduced a new family of heavy-duty conveyor belt cleaner designs, engineered so the blade cartridge can be pulled away from the belt for safe access and replaced by a single worker.
The U.S. firm developed the Safe to Service (STS) blades to secure both primary and secondary cleaners rigidly to the conveyor mainframe, while offering more versatility and easier access.
Initially available on the Martin QC1 Cleaner HD, Martin QC1 Cleaner XHD and Martin SQC2S Secondary Cleaner, external servicing reduces confined space entry and eliminates reach-in maintenance, while facilitating faster blade replacement. The result is said to be greater safety and efficiency, with less downtime.
“Routine maintenance and replacement of blades that require reach-in or chute entry is an unpleasant and potentially dangerous task for workers,” said Daniel Marshall, product engineer for Martin Engineering. “We developed the STS system so operators could work on the product safely from outside the chute wall, without breaking the plane of entry.”
The system was originally developed for an international client who needed a safer method for workers to replace cleaner blades on the company’s large conveyor system. After field-testing, operators found that the STS design lowered the chance of injury and required fewer workers to perform maintenance, contributing to greater overall process efficiency.
