Abstract
An elevator system driven by a linear motor and elevated up and down in a hoistway including a cage, a counter weight and a hoisting rope having both ends by and from which the cage and the counter weight are suspended so as to be alternatively elevated up and down in the hoistway. A reaction plate is supported by the side wall of the hoistway throughout an entire vertical length of the side wall. A stator is secured to the counter weight at a portion facing the reaction plate with a small gap therebetween and a guide is secured to the counter weight for guiding the elevation thereof. The guide is a guide roller structure comprising a support plate secured to the counter weight by a bolt, an adjusting rod engaged with the support plate on a side opposing to the reaction plate for adjusting a securing position of the support plate and a guide roller abutting against the reaction plate so as to be rollable therealong. The guide roller may be replaced with a guide shoe secured to the counter weight and mounted to the reaction plate to be slidable therealong. The guide may include a combination of a guide shoe and a guide roller.
