Abstract
An elevator hoisting device including a stator forming a primary side of a linear motor disposed on an wall of a hoistway adjacent to its ceiling, a tape-shaped amorphous metallic member for hanging down over a pulley to support at opposite ends thereof an elevator car and a counter weight so as to cause its pendent portion connected to the counter weight to be close to the stator through a non-magnetic member with a low coefficient of friction to form a secondary conductor of the linear motor. The non-magnetic member and therefore the adjacent surface of the stator is somewhat tilted to the vertical downward toward the wall of the hoistway.
