Abstract

1495652 Acceleration responsive brakes GRANGES FAHRZEUGTECHNIK GmbH 19 Aug 1975 34382/75 Heading F2E [Also in Division B8] An emergency brake for arresting a moving load, comprises a spindle 10 rotatably mounted between walls 4, 5, of a casing 27, 28 and spring biased to wind a load safety tie thereonto and a flywheel control element 20, 21 which normally rotates with the spindle 10 but upon acceleration of the spindle above a predetermined limit, rotates relative to the spindle causing the element 20, 21 to move axially of the spindle into an arrest position whereby the spindle is also braked. The control element 20 having the flywheel 21 secured thereto is in screw threaded engagement with a coarse thread 13 on the spindle 10, the element normally being biased by a spring 25 against a ring 16 on the spindle, at which position serrations 24 on the element 20 are out of engagement with serrations 8 formed on a member 9 secured to the wall 5 for journalling the spindle 10. During normal powered lifting and lowering- of a load each safety tie associated therewith winds and unwinds with and against a spiral spring 17 secured between the wall 4 and the end 14 of the spindle. Upon acceleration of the load and hence the spindle 10, at a greater magnitude than that possible by the flywheel 21, as determined by its mass, the spring 25 and the threaded connection 13, the spindle rotates relative to the flywheel element 20, 21 which therefore threads itself along the spindle until the serrations 8 and 24 interengage to halt the spindle.
