    • An improvement to cable conveyor system using a pneumatic cylinder system for keeping a cable tight is provided for preventing damage to the system if the cable stretches/fails or is too loose. The fluid cylinder/piston applies a force on the cable proportionate to the pressure that is regulated to the cylinder during normal operation of the cable conveyor system. The relative position of a magnetic switch and a magnet on a piston in the cylinder, provides a way to sense a lack of tension in the cable and shut the system down before damage is done to the conveyor. Likewise, if the cable stretches or fails, a carriage having an idler thereon, will move close enough to a proximity switch to cause the proximity switch to shut down the system.
    • 提供使用气压缸系统保持电缆紧密度的电缆输送系统的改进,以防止电缆延伸/失效或过松时对系统造成损坏。 流体缸/活塞在电缆输送系统的正常操作期间,将电缆上的压力与调节到气缸的压力成比例。 磁性开关和磁体在气缸中的活塞上的相对位置提供了一种检测电缆中缺少张力的方法,并在损坏传送带之前关闭系统。 同样地,如果电缆延伸或失效,则其上具有惰轮的滑架将移动到接近开关足够近以使接近开关关闭系统。
