What is the main use of the shuttle at the front end of the stacker?

The main use of the shuttle at the front end of the stacker is indeed to freely lift and tilt forward or backward. This functionality is crucial for the operation of a stacker, as it allows the operator to position loads accurately and securely. The ability to tilt the load forward or backward facilitates a more precise placement of items as well as safe stacking and unstacking. This capability is particularly important when dealing with loads of varying sizes and shapes, ensuring that items can be handled with maximum efficiency without compromising stability.

When the shuttle can freely lift and tilt, it enhances the overall maneuverability of the stacker, allowing operators to navigate tight spaces and adjust the load orientation for different tasks. Such versatility is essential in warehouse settings and other scenarios where material handling involves a variety of goods.
