Fluid clutches are used on equipment that experiences?

Fluid clutches are specifically designed to handle applications that involve shock loading, which refers to sudden and extreme forces that can occur during equipment operation. These clutches use a fluid medium to transfer torque, allowing for a smoother engagement and disengagement process compared to mechanical clutches.

When shock loading occurs, a fluid clutch can accommodate the sudden changes in load and can absorb the energy, reducing the impact on the machinery. This capability decreases wear and tear on components and helps maintain smoother operation in applications where starting and stopping can introduce significant stress to the system.

In contrast, equipment that operates under heavy load shifting typically does not require the additional benefits of a fluid clutch, as mechanical clutches might suffice. Similarly, equipment that runs at a constant speed or experiences low friction does not need the shock absorption features that fluid clutches provide, as these conditions do not introduce the same types of mechanical stresses.
