What must be checked regularly to ensure the safety of an elevator system?

Regular checks on the condition of the hoisting cable, the amount of hydraulic fluid, and the pressure in the hydraulic tank are all critical for maintaining the safety and reliability of an elevator system.

Inspecting the condition of the hoisting cable is essential because it supports the entire weight of the elevator car and its passengers. Worn or frayed cables can lead to failures that may result in dangerous situations.

Monitoring the amount of hydraulic fluid is also crucial, especially in hydraulic systems. Low fluid levels can lead to poor performance or even failure of the elevator to operate correctly, which can jeopardize passenger safety.

Finally, checking the pressure in the hydraulic tank is important to ensure that the hydraulic system is functioning effectively. Proper pressure is necessary for maintaining the elevator's lifting capabilities; abnormal pressure levels could indicate leaks or malfunctions that pose risks.

Together, these inspections represent a comprehensive approach to elevator safety, reinforcing the importance of regular maintenance and checks to prevent accidents and ensure safe operation.
