    • An elevator without counterweight may Include an elevator car suspended by a hoisting rope, a traction sheave operatively connected to the elevator car by the hoisting rope, and a brake structure configured to engage with the traction sheave in a braking operation in an upward motion and a downward motion of the elevator car. The brake structure may include first and second brake elements. The first brake element may include a surface engageable with the traction sheave, and first contact and sliding surfaces. The second brake element may include second contact and sliding surfaces. The first sliding surface may slide along the second sliding surface relative to the second brake element when the elevator car moves with the upward motion. The second contact surface may contact the first contact surface to stop a sliding motion of the first brake element when the elevator car moves with the downward motion.
    • 没有配重的电梯可以包括由提升绳索悬挂的电梯轿厢,通过提升绳可操作地连接到电梯轿厢的牵引滑轮,以及构造成在向上运动的制动操作中与牵引滑轮接合的制动结构, 电梯轿厢向下运动。 制动结构可以包括第一和第二制动元件。 第一制动元件可以包括可与牵引滑轮接合的表面,以及第一接触和滑动表面。 第二制动元件可以包括第二接触和滑动表面。 当电梯轿厢以向上运动移动时,第一滑动表面可相对于第二制动元件沿着第二滑动表面滑动。 当电梯轿厢以向下运动移动时,第二接触表面可接触第一接触表面以停止第一制动元件的滑动运动。

    • An elevator may include an elevator car, a set of hoisting ropes, a traction sheave, and a compensating device. The set of hoisting ropes may include first and second rope portions. The elevator car may include one or more first diverting pulleys from which the first rope portions extend upward. The elevator car may include one or more second diverting pulleys from which the second rope portions extend downward. The first rope portions may be under a first rope tension. The second rope portions may be under a second rope tension that is different from the first rope tension. The compensating device may act in substantially opposite directions on the first and second rope portions. The compensating device may produce an auxiliary force acting substantially in a same direction as the first rope tension.
    • 电梯可以包括电梯轿厢,一组提升绳索,牵引绳轮和补偿装置。 提升绳索可以包括第一和第二绳索部分。 电梯轿厢可以包括一个或多个第一转向滑轮,第一绳索部分从该第一转向滑轮向上延伸。 电梯轿厢可以包括一个或多个第二转向滑轮,第二绳索部分从该第二转向滑轮向下延伸。 第一绳索部分可能处于第一绳索张力之下。 第二绳索部分可能处于不同于第一绳索张力的第二绳索张力。 补偿装置可以在第一和第二绳索部分上以基本上相反的方向作用。 补偿装置可以产生基本上沿与第一绳索张力相同的方向作用的辅助力。
