What component connects the plunger to the car sling in hydraulic elevators?

The correct response highlights the role of the platen in the hydraulic elevator system. The platen is a crucial component that directly connects the plunger to the car sling. This connection is essential for transferring the force generated by the hydraulic system to the elevator car itself, allowing it to move up and down smoothly.

The design of the platen ensures that when hydraulic fluid is pumped into the cylinder, the resulting pressure forces the plunger outwards. This outward movement of the plunger then pushes against the platen, lifting the car sling and subsequently the elevator car. Proper functioning of the platen is vital for the safety and efficiency of the elevator operation, as it must withstand the weight of the elevator and its load while providing reliable performance.

Understanding this connection helps in recognizing the importance of each component in the hydraulic system, where the platen plays a key role in facilitating movement and ensuring stability.
