Abstract
1,118,399. Brakes. ALIMAK-VERKEN A.B. 25 April, 1967, No. 18912/67. Heading F2E. [Also in Division B8] A centrifugal brake, mounted on a hoist cage to prevent over-speeding of the cage, is provided with a gear wheel 11 which engages a rack on the hoist mast. When the cage attains a predetermined speed, pawls, Fig. 3 (not shown), which are mounted on pivots 16 on a member 18 secured to the gear wheel shaft 12, pivot outwardly against the action of a spring and engage projections on a drum 20. The drum then rotates in a casing 15 causing a screw sleeve 37 to move axially along a screw shaft 23 secured to the drum. This axial movement of the sleeve compresses a spring 22 and causes the drum to move axially into engagement with a removable brake shoe 34. Movement of the sleeve 37 causes a pin 25 to actuate a switch 24 to cut out the hoist drive motor which is mounted on the cage and which drives a gear-wheel engaging the rack on the mast. In a second embodiment, Figs. 6, 7 (not shown), the brake acts for both directions of rotation of the gear wheel 11. In a modification, Figs. 8, 9 (not shown), the gear-wheel on the brake shaft 12 meshes with two further gear-wheels which engage the rack.
