Hydraulic shock absorber for elevator

In a hydraulic shock absorber for an elevator, at least one cylindrical intermediate plunger is inserted into a base cylinder. An upper stage plunger is inserted into the intermediate plunger. An orifice is formed in the bottom surface portion of the upper stage plunger. A pin rod is installed upright in the base cylinder. The pin rod is inserted into the orifice midway through stroking of the upper stage plunger. The intermediate plunger and the upper stage plunger can be returned to the non-loading position by a return spring.
