  • Vertical conveying apparatus
    Patent number: 4240529
    Abstract: Apparatus for conveying goods in vertical direction, such as a stacker crane or elevator, with a lifting unit and an emergency braking system which influences the lifting unit as soon as a preselectable speed is exceeded. The braking system comprises two wedges connected to an endless rope drive moving synchronously with the lifting unit. The rope drive moves only up to a preselectable top speed, and as soon as a speed difference between rope drive and lifting unit occurs, the brake wedges are activated and decelerate the lifting unit progressively until it stops.
