The cart is equipped with two circuits of Torlon balls (lower) and two circuits of Delrin balls (upper) for smooth movement. The cart can accommodate single, double, or triple pulleys with or without a ringot. The monobloc extruded body is made of high-strength anodized aluminum, while the steel parts are made of AISI 316 stainless steel. The side slots make it easy to maintain and clean the balls. The cart comes with a standard shackle or a special “stand-up” connection for maximum safety.
