Benefits
Patented Replaceable Wing Lagging® (RWL™) is an innovative way to cover new wing pulleys and recover old wing pulleys. Engineered sections are made for specific pulley sizes and effectively cover the pulley wings in a protective strip of rubber and
steel and are an ideal way to save money and time. Can be installed on new pulleys in our plant or on the pulley in the field.
- Significantly reduces noise and vibration commonly associated with wing pulleys
- Helps prevent damage to the belt bottom cover
- No layout necessary to fit to existing pulleys
- No cutting necessary: eliminates waste and scrap pieces
- Reduces conveyor downtime and reduces costs associated with pulley installation and removal
- Easy on/Easy off principle means Douglas® RWL™ may be installed in the field without removing the pulley or the conveyor belt
- Order RWL™ with any new Douglas® pulley and we will install it for free
