巨力起重滑車/進口軸承可注油巨力滑車。 巨力牌起重滑車是一種能以較小的力提升較重物品的輕小型起重設備。起重滑車由定滑輪和動滑輪組成,并帶有吊掛件。定滑輪位置固定不變,用以改變力的方向;動滑輪與重物一起升降,用以減小拉力。起重滑車可單獨使用,也可與絞車等配合使用,是許多起重機械起升機構的基本組成部分。由于使用、攜帶方便,在起重安裝作業(yè)中廣泛應用。
Juli lifting pulley / imported bearing oiling Juli pulley. Juli brand is a kind of lifting pulley can enhance the heavy goods with a small force of the small light lifting equipment. Lifting pulley by the fixed pulley and the movable pulley, and a hanger. The fixed pulley position is fixed and fixed, and the direction of the force is changed; the movable pulley is lifted with the heavy object to reduce the tension force. Since weight pulley can be used alone, and winches, etc. with the use of many crane hoisting mechanism of the basic part. Due to the use, carry convenient, widely used in the lifting of the installation work.
滑輪依據杠桿原理設計的簡單機械。由一個周邊有溝槽的圓盤和一條跨過圓盤的繩索(或膠帶、鋼索、鏈條等)所組成。通過繩索繞中心軸的運動來實現機械效能,達到省力或改變力的方向的作用。
Pulley according to the lever principle design of simple machinery. By a peripheral grooved disc and a rope across the disk (or tape, wire rope, chain etc.). Through the rope around the central axis of the movement to achieve mechanical efficiency, to achieve the role of effort or change the direction of the force.
