Abstract
A method and a catching device are used to catch a traveling body in an elevator system wherein traveling body is movable along a rail. The catching device includes a first braking element, a second braking element, a first guide element, a second guide element and an actuating element. The first braking element and the second braking element are brought into contact with the rail for braking. A first linear bearing is formed between the first braking element and the first guide element and a second linear bearing is formed between the second braking element and the second guide element. Both guide elements are moved between a rest position and a braking initial position, the actuating element moving the two guide elements from the rest position into the braking initial position.
