BALANCER |
| 摘要 |
The invention relates to a balancer (1) for raising, holding and lowering a load, comprising a cable drum (7) which can be rotated in a manner actuated by pressure medium and has a cable for bearing the load, which cable can be unwound from and wound onto said cable drum (7), and has a device for emergency braking of the cable drum (7) if a defined rotational speed is exceeded, which device for emergency braking comprises at least one locking element (16) which is fastened to the cable drum (7), is held in a freewheeling position in a spring-loaded manner and can be moved into a deployed locking position in a manner which is actuated by centrifugal force, in which locking position the rotation of the cable drum (7) is blocked by virtue of the fact that the locking element (16) is in engagement with a stop which is stationary relative to the cable drum (7). The balancer (1) according to the invention is distinguished by the fact that, after its triggering, the locking element (16) is held in a deployed position when said locking element (16) and the stop which interacts with it move out of engagement. |

1. A balancer for raising, holding and lowering a load, comprising a cable drum which is actuated by pressure medium and has a cable for bearing the load, which cable can be unwound from and wound onto said cable drum, and has a device for emergency braking of the cable drum if a defined rotational speed is exceeded, which device for emergency braking comprises at least one locking element which is fastened to the cable drum, is held in a freewheeling position in a spring-loaded manner and can be moved into a deployed locking position in a manner which is actuated by centrifugal force, in which locking position the rotation of the cable drum is blocked by virtue of the fact that the locking element is in engagement with a stop which is stationary relative to the cable drum, characterized in that, after its triggering, the locking element is held in a deployed position when said locking element and the stop which interacts with it move out of engagement. |
