What is the primary function of the left-hand joystick in a two-joystick manipulator system?

In a two-joystick manipulator system, the left-hand joystick typically controls functions related to the movement of the boom. Specifically, it is responsible for the boom's left and right swing, as well as its extension and retraction. This functionality is crucial for positioning the boom in various directions and adjusting its reach to effectively perform lifting tasks.

The boom left/right swing allows the operator to pivot the boom horizontally, aligning it with the load or the intended area of operation. The extend/retract function enables the operator to adjust the length of the boom, ensuring they can lift loads from a distance or bring them closer as needed. This control is essential for safe and accurate maneuvering, which is particularly important in tight spaces or during intricate operations.

Understanding the role of the left-hand joystick helps operators effectively manage crane movements and maintain control during complex lifting scenarios.
