The emergency rescue device has as a drive element a crank (16, 17) with a flexible shaft (15) and can be actively connected to the lift drive by a gearwheel (3) which moves along its toothed flanks without changing the engagement depth. The gear wheel gear is preferably formed as a crown wheel gear , a spur wheel gear or as an internally cogged gear. The crank and remote control operating elements (14,18) are mounted in an operating recess (24) set in a shaft wall or door front. |
