Product IntroductionThe suspended sheave is specialized equipment used in vertical shaft construction to support and guide the steel wire rope of the sinking winch. Based on the performance of the sinking winch, it is categorized into single-groove and double-groove types.
The single-groove suspended sheave is primarily used for suspending hoisting platforms, formwork, and stabilizing ropes, while the double-groove suspended sheave is more commonly employed for suspending ventilation ducts, pipes, and other construction materials. and ductwork during construction.
Both double-groove and single-groove pulleys consist primarily of a rope wheel, fixed shaft, and bearing housing. The inner bore of therope wheel is fitted with an alloy copper bushing. During operation, the pulley rotates around the shaft. An oil cup is mounted on the hub to lubricate the interface between the shaft and the copper bushing. The double-groove pulley features two rope wheels separated by an adjustment ring, allowing for the regulation of the distance between the two wheels.
