    • A crane return system is used for returning a crane component to a home position when there is a loss of power. A crane includes a bridge with a plurality of main wheels adapted to travel along at least one rail. The crane return system includes a plurality of auxiliary drive wheels supported by the bridge, the auxiliary drive wheels movable between a first position, in which the auxiliary drive wheels are recessed from the rail, and a second position, in which the auxiliary drive wheels are in contact with the rail. When power is supplied to the crane return system the auxiliary drive wheels are in the first position. A hydraulic fluid pressure vessel stores hydraulic fluid, wherein a substantially fixed mass of hydraulic cylinder is interconnected with the auxiliary drive wheels and selectively fluidly communicates with the hydraulic fluid pressure vessel. When power is lost to the crane, hydraulic fluid is supplied to the hydraulic cylinder to extend the hydraulic cylinder and thereby move the auxiliary drive wheels from the first position to the second position. A drive motor is interconnected with the auxiliary drive wheels and selectively fluidly communicates with the hydraulic fluid pressure vessel. When the auxiliary drive wheels are in the second position, hydraulic fluid is diverted from the hydraulic cylinder and supplied to the drive motor to rotate the auxiliary drive wheels and move the bridge toward a home position.
    • 起重机返回系统用于在发生电力损失时将起重机部件返回原位。 起重机包括具有适于沿着至少一个轨道行进的多个主轮的桥。 起重机返回系统包括由桥支撑的多个辅助驱动轮,辅助驱动轮可在辅助驱动轮从轨道凹入的第一位置和辅助驱动轮之间移动的第二位置 与铁路接触。 当向起重机返回系统供电时,辅助驱动轮处于第一位置。 液压流体压力容器存储液压流体,其中液压缸的基本上固定的质量与辅助驱动轮互连,并与液压流体压力容器选择性地流体连通。 当起重机损失动力时,向液压缸供给液压油以延伸液压缸,从而将辅助驱动轮从第一位置移动到第二位置。 驱动马达与辅助驱动轮互连,并与液压流体压力容器选择性地流体连通。 当辅助驱动轮处于第二位置时,液压流体从液压缸转向并提供给驱动马达以使辅助驱动轮旋转并将桥移向原位。

    • A hoist apparatus (10) including a rope sensing device (14) for detecting rope fouling events. The rope sensing device (14) includes a lever arm (74) having a first end portion (74g), a second end portion (74h), and a pivot point (74j) located between the first (74g) and second (74h) end portions along the lever arm (74). The lever arm (74) is pivotably mounted to a frame (18) of the hoist apparatus for movement between a sensing position and a fouled position. A follower (78) is connected to the first end portion (74g) and positioned adjacent and spaced from a drum (30) of the hoist apparatus such that rope (38) winds on to the drum spaced from and relative to the follower (78) when the rope sensing device is in the sensing position. A switch actuator (82) is connected to the second end portion (74h) adjacent a switch (86) such that the switch is actuated to a motor stop position when a rope fouling event occurs.
    • 一种提升装置(10),包括用于检测绳索污染事件的绳索感测装置(14)。 绳索检测装置(14)包括具有第一端部(74g),第二端部(74h)和位于第一(74g)和第二(74h)之间的枢转点(74j)的杠杆臂(74) 端部沿着杠杆臂(74)。 杠杆臂(74)可枢转地安装在起重设备的框架(18)上,用于在感测位置和污损位置之间移动。 从动件(78)连接到第一端部部分(74g)并定位成与提升装置的滚筒(30)相邻并间隔开,使得绳索(38)卷绕到鼓上,与滚筒间隔开并相对于从动件(78) )当绳索感测装置处于感测位置时。 开关致动器(82)连接到与开关(86)相邻的第二端部(74h),使得当发生绳索结垢事件时,开关被致动到电动机停止位置。
