In a truck crane, a bidirectional hydraulic lock, often referred to as a bidirectional hydraulic locking valve or a bidirectional hydraulic brake, is a component that is used to lock the hydraulic system in both directions. This type of lock is commonly employed in hydraulic systems to secure a load or prevent undesired movement. Here are key points about the bidirectional hydraulic lock in a truck crane:

1. Functionality: The bidirectional hydraulic lock is designed to secure or hold the position of hydraulic cylinders or hydraulic motors in both directions. It can prevent the unintentional movement of the load, providing stability and safety during crane operations.

2. Hydraulic Cylinder or Motor Locking: The lock is typically applied to hydraulic cylinders or hydraulic motors involved in specific crane functions, such as lifting, lowering, extending, or retracting. It ensures that these components remain stationary when the lock is engaged.

3. Hydraulic System Integration: The bidirectional hydraulic lock is integrated into the hydraulic system of the truck crane. It is connected to the hydraulic circuit and controlled by the operator through the crane's control system.
