The next generation of troughing and return rollers are made of lightweight, high strength, corrosion- and abrasion-resistant composite materials. Despite the heavy-duty construction and solid performance, the rollers are 40%-50% lighter than steel. In most cases, a CoreTech roller requires only one person to lift, carry, and place, requiring less manpower and increasing productivity, while adhering to one-person lifting limits. With low breakaway mass, the rollers also require less energy or torque to start rotation. This, plus a low running friction, decreases power consumption and can contrib-ute to lower electric bills.
