Martin Engineering introduces new pin latch
By Andrew Macklin
April 6, 2016 – Martin Engineering has introduced its new Pin Latch secondary belt cleaner, a tungsten carbide-tipped secondary cleaner that slides in and out for service without requiring any tools.
The design features a square, tabbed mainframe with segmented blades connected by a simple pin mechanism, allowing easy access and quick blade replacement by semi-skilled personnel.
The pin latch design provides adjustable tension for varying conditions, such as belt speed, material being conveyed and belt cleaner position relative to the head pulley. It will handle belt speeds up to 1,000 feet per minute (5.1 meters per second), and the versatile unit accommodates belt rollback. The carbide tip is acid and abrasion resistant, and the assembly is well suited for use on belts with mechanical splices, smoothly adapting to and riding over the splices without damaging the splice, belt or blade.
Blade replacement can be performed with a greatly reduced risk of errors, and the narrow blades conform readily to conveyor belt profiles.
The Martin Pin Latch secondary belt cleaner delivers excellent cleaning performance with quicker blade recovery, and provides the versatility to adjust blade performance to match a wide range of application characteristics. It is considered a preferred upgrade for Martin SQC2 and SC16 secondary cleaners.
