The new QC1+ is shown being cut to length on-site.
The new design uses a hole in the aluminum extrusion to keep the blade firmly in position.
The torque tube lock collars are designed to be an interference fit with the square mainframe. To assemble, the tube is installed first, then the collars are added and set in position. The length of the mainframe is adjusted next, and finally the set screws on the collars are tightened down. In most applications, the simple sequence can be performed by a single worker in just a few minutes. The new design is compatible with any of the Martin tensioning systems.
Urethane belt cleaner blades from Martin Engineering are designed with the company’s patented Constant-Area Radial Pressure (CARP) technology to deliver consistent cleaning
throughout all stages of blade life. Martin designed and developed the concept, patented in 1990, which has been adopted worldwide. The innovative engineered cleaners maintain the same contact area, blade angle and pressure to effectively remove virtually any type of material carryback, even as the blade wears down over time.
Five different urethane formulations are currently available for the QC1+:
• Standardorangeformostapplications(approvedby MSHA for mining applications)
• Brownforchemicalresistance
• Greenforhigh-temperatureapplications
• Clearfordryproductssuchassandandgravel
• Navybluefortackymaterialssuchascement
The product is initially being launched in the USA, followed by other regions over the coming year.
“This design introduces a new generation of belt cleaning technology,” Mueller added. “It’s a truly revolutionary product that delivers the cleanest belt and the longest blade life -- at the lowest cost.”
