In a type-H support system, which component is responsible for pulling the support arm and support black back when the ramp reaches its lowest position?

In a type-H support system, the component responsible for pulling the support arm and support block back when the ramp reaches its lowest position is indeed the drawback cable. This cable plays a crucial role in ensuring that the ramp can be retracted smoothly after it has been lowered. When the ramp reaches its maximum downward extension, the tension in the drawback cable helps to engage the mechanism that brings the ramp back up to its resting position, ensuring stability and functionality in the operation of the support system.

The other components mentioned have different functions. For instance, the support arm mechanism primarily provides the necessary movement and structural integrity for the ramp but does not actively retract it. A weight counterbalance might assist in managing the weight of the ramp for better control but does not actively pull the ramp back. The hydraulic actuator is responsible for lifting and lowering the ramp, but it does not perform the retraction task. Therefore, the drawback cable is specifically designed for the retraction process in the type-H support system.
