Definitions
- This invention relates to an elevator shock absorber for mitigating the impact on a car or a counterweight.
- a hydraulic buffer for an elevator in which a plurality of plungers, which are successively formed with a small diameter and extendable in the vertical direction, are entered into a base cylinder filled with hydraulic oil.
- a vessel has been proposed.
- a coil spring for returning the position of the plunger after compression of the hydraulic shock absorber is connected between the plungers of each stage. The positions of the plungers at each stage are restored by being displaced in a direction in which the upper and lower plungers are separated from each other by the biasing force of the coil spring (see Patent Document 1).
