What type of components are hydraulic foot brakes categorized as?

Hydraulic foot brakes are categorized as load-controlling parts because they play a crucial role in managing the movement and stopping of the crane's load. These components allow the operator to control the descent of the load and stop it safely, ensuring that the load is held securely when necessary. They are essential for maintaining stability and safety when the crane is in operation, especially when lifting or lowering heavy loads.

In contrast, other categories such as load-bearing parts refer specifically to components that support and carry the actual weight of the load, while operational parts are those that facilitate the functioning of the crane without being directly involved in controlling the load itself. Therefore, the categorization of hydraulic foot brakes as load-controlling parts highlights their specific function in regulating the load's movement and enhancing overall safety.
