What is the common pressure range for hydraulic elevator systems?

The common pressure range for hydraulic elevator systems typically falls between 150 to 300 psi. This range is essential for the proper functioning of hydraulic systems, as it provides the necessary force to lift the elevator car smoothly and efficiently. Within this pressure range, hydraulic fluids can effectively transmit power through the system, ensuring that the cylinder operates correctly and that the elevator responds promptly to commands.

In hydraulic elevators, the oil pressure must be sufficient to overcome the weight of the elevator car and any additional load it may carry. Operating outside of this range can lead to inefficient operation or potential system failure. Therefore, the selected answer accurately reflects the operational standards for hydraulic elevator systems, ensuring safety and reliability in their design and usage.
