    • An arrangement for equalizing rope force of an elevator may include: a hoisting machine, set of hoisting ropes, traction sheave, elevator car, guide rails, and compensating device. The hoisting machine may engage the hoisting ropes via the traction sheave. The elevator car may be at least partially supported by the hoisting ropes to move the elevator car. The elevator car may move along the guide rails. The compensating device may include first and second tensioning devices. The first tensioning device may be spaced apart from the second tensioning device. The first and second tensioning devices may be interconnected via a transmission device that transmits rotary motion. A first end of the set of hoisting ropes may be secured to a point in conjunction with the first tensioning device. A second end of the set of hoisting ropes may be secured to a point in conjunction with the second tensioning device.
    • 用于平衡电梯的绳索力的装置可以包括:起重机,起重绳索组,牵引滑轮,电梯轿厢,导轨和补偿装置。 曳引机可以通过牵引滑轮接合起重绳索。 电梯轿厢可以至少部分地由提升绳索支撑以移动电梯轿厢。 电梯轿厢可以沿导轨移动。 补偿装置可以包括第一和第二张紧装置。 第一张紧装置可以与第二张紧装置间隔开。 第一和第二张紧装置可以经由传递旋转运动的传动装置相互连接。 一组提升绳索的第一端可以固定到与第一张紧装置结合的点上。 一组提升绳索的第二端可以固定到与第二张紧装置结合的点上。

    • An elevator may include an elevator car, counterweight, set of hoisting ropes, and one or more rope pulleys. The elevator car and counterweight may be suspended on the set of hoisting ropes. The one or more rope pulleys may be provided with one or more rope grooves. Each rope groove may have a groove bottom and groove sides. At least one rope pulley may have a coating adhesively bonded to it. At the groove bottom, a thickness of the coating may be at most about 3 mm. At the groove bottom, the thickness of the coating may be substantially less than half a thickness of the at least one hoisting rope running in the one or more rope grooves. At the groove sides, the thickness of the coating may be at most about 3 mm. The coating may be thicker at the groove bottom than at the groove sides.
    • 电梯可以包括电梯轿厢,配重,一组提升绳索和一个或多个绳索滑轮。 电梯轿厢和配重可以悬挂在一组起重绳索上。 一个或多个绳轮可以设置有一个或多个绳槽。 每个绳槽可以具有凹槽底部和槽侧。 至少一个绳索滑轮可以具有粘合到其上的涂层。 在凹槽底部,涂层的厚度可以至多约3mm。 在凹槽底部,涂层的厚度可以基本上小于在一个或多个绳槽中运行的至少一个提升绳索的一半的厚度。 在槽侧,涂层的厚度可以至多约3mm。 凹槽底部的涂层可能比凹槽侧更厚。

    • 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。
