<p>#CMT# #/CMT# The drive has a brake device including brake levers (5, 6) with a compression spring (2) that exert a spring force to move brake linings (13, 16) to cause a braking force on a brake drum (14). A brake magnet (4) lifts the brake levers against the spring force, and includes a switch for monitoring a minimum distance between a plunger of the brake magnet and a brake magnet housing. The switch is arranged on a brake magnet rod, and executes movement of the brake magnet rod relative to the brake magnet housing. #CMT# : #/CMT# An independent claim is also included for a method for the construction of an elevator drive. #CMT#USE : #/CMT# Elevator drive. #CMT#ADVANTAGE : #/CMT# The simple construction of the drive realizes end-position monitoring. The drive facilitates direct switch off of the drive, before the brake fails or before the occurrence of dangerous condition for the users of the elevator. The provision of switch in the drive detects and prevents the failure of the brake. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an elevator drive with a brake device with a compression spring and a brake magnet. 2 : Compression spring 4 : Brake magnet 5, 6 : Brake levers 13, 16 : Brake linings 14 : Brake drum.</p> |
