4 WORKING PRINCIPLES

The governor is of the centrifugal type, and is able to work either upwards or downwards.
As mentioned above, the designed object is fixed into the car or into the sling of the lift, and it can be placed either
above or below both. The rope, anchored to the ceiling and to the pit floor, passes through the governor, along the
pulley jaws. This way, when the car reaches its tripping speed, the rope-governor relative movement will lock it. This
governor locking will drive the safety gear and will stop the car movement.
Working diagram is as follows:
Such is the interlocking process that, when the car speed exceeds a pre-set level (governor tripping speed), the
centrifugal system, together with the pulley, interlocks with the governor "locking system", which, in turn, is coupled
to the driving bar by means of an auxiliary component. At this moment, the main pulley locks and the friction between
the rope and the pulley is transferred to the safety gear through the auxiliary component and the driving bar. The
safety gear, on wedging, will cause the car to stop.
It is important to remark that the connection between governor and safety gear is not carried out through the governor
