Abstract
The invention relates to a suspension arrangement for a hydraulic elevator. In addition to a normal diverting pulley mounted on the top end of the piston of the hoisting cylinder, the arrangement includes an additional diverting pulley placed at the bottom end of the cylinder. The first ends of the elevator ropes are fixed to a rope anchorage in the car frame of the elevator, from where the ropes are passed over the diverting pulley on the top end of the piston to the additional diverting pulley, from which additional diverting pulley the ropes are further passed to an adapter moving with the top end of the piston, with the second ends of the ropes being attached to the adapter.
