Compensation and rope elongation arrangement

An arrangement for compensating an elongation of suspension and compensation ropes of an elevator, comprising:

• an elevator car;
• a counterweight;
• suspension and compensation ropes linking said elevator car and said counterweight;
• and
• a buffer structure fixed in place below the counterweight and provided with means for adjusting the buffer structure in the vertical direction while the buffer structure remains fixed in place.

An elevator including a compensation rope arrangement, comprising:

• an elevator car;
• a counterweight;
• a set of elevator suspension ropes on which said elevator car and said counterweight are suspended;
• and
• a set of compensating ropes operatively associated with said elevator car and said counterweight;
• wherein a suspension ratio of the compensating ropes corresponds to a product of the suspension ratio of the suspension ropes and a constant which is greater than one, and the suspension ratio of the suspension ropes on the side of the car is the same as the suspension ratio of the suspension ropes on the side of the counterweight.

An elevator arrangement comprising:

• an elevator in an elevator shaft;
• a counterweight in the elevator shaft and connected to said elevator by suspension and compensation ropes;
• and
• a buffer structure, said buffer structure including:
• a base having a first surface for attachment to the elevator shaft;
• a buffer part having a top surface for contacting the counterweight;
• and
• adjustment means connected to said base and to said buffer part, for adjusting a distance between the first surface and the top surface.

A buffer structure for use in combination with an elevator system, comprising:

• a base for connection to a first surface in an elevator shaft;
• a buffer part having a top surface for contacting a component of the elevator system;
• and
• an adjustment screw connected to said base and to said buffer part, said adjustment screw adjusting a distance between the first surface and the top surface as said adjustment screw is rotated.
