Provided is an elevator wherein a balance wheel device has a balance wheel guide rail, a balance wheel frame which can move vertically along the balance wheel guide rail, a balance wheel guide shoe which is in contact with and moves along the balance wheel guide rail, and a balance wheel body. The coefficient of friction between the balance wheel guide shoe and the balance wheel guide rail duringthe ascent of the balance wheel guide shoe is greater than the friction of coefficient between the balance wheel guide shoe and the balance wheel guide rail during the decent of the balance wheel guide shoe.
在电梯中,平衡轮装置具有:平衡轮导轨;平衡轮框,其能够沿着平衡轮导轨上下移动;平衡轮导靴,其与平衡轮导轨接触并沿着平衡轮导轨移动;以及平衡轮主体。平衡轮导靴上升时的平衡轮导靴与平衡轮导轨之间的摩擦系数比平衡轮导靴下降时的平衡轮导靴与平衡轮导轨之间的摩擦系数大。
