Hydraulic cushionride elevator |
摘要 |
A mechanism is placed between a plunger and an elevator car to damp the effects of stick-slip encountered during elevator start-up and to minimize the probability of damage to a plunger/cylinder assembly if the elevator car is stopped in an emergency. The mechanism comprises a self-leveling hydraulic shock absorber that operates independently of any stick-slip between the plunger and cylinder.
