What is the minimum clearance from the buffer to the bottom of the car for a hydro system?

The correct answer specifies that the minimum clearance from the buffer to the bottom of the car for a hydraulic elevator system is 2 feet. This requirement is significant due to the specific operational characteristics of hydraulic elevators.

Hydraulic systems operate using fluid pressure to lift the elevator car, and they require a certain clearance to accommodate the potential movement and mechanics involved in this system. The added clearance allows for safe operation, providing space for both the buffers and any potential displacement of the elevator car during normal functioning or in case of a malfunction.

The distinction made in the answer indicates a difference in clearance requirements between hydraulic systems and other types of elevators, emphasizing that each system has been designed with specific safety standards and operational dynamics in mind. Understanding these clearance requirements is crucial for ensuring the safe installation and operation of elevators in accordance with building codes and safety regulations.
