What direction must the stacker be maintained when the load is moving forward or backward in the middle area of two rows of goods?

Maintaining the stacker in a straight direction when the load is moving forward or backward in the middle area of two rows of goods is crucial for several reasons. Firstly, keeping the stacker straight enhances stability and control. It minimizes the risk of the load swinging or shifting unexpectedly, which can occur if the stacker is not aligned properly. This is especially important in tight spaces, where navigating past rows of goods can be challenging.

Furthermore, a straight stacker helps ensure that the load remains balanced and evenly distributed, reducing the likelihood of accidents or spills. When operating a stacker with a load in a confined area, the operator's visibility and control over the machinery are also improved, allowing for more precise maneuvering.

Other choices, such as allowing the stacker to sway slightly or turning it towards an exit, introduce unnecessary risks. Swaying may lead to loss of control over the load, while turning towards an exit does not take into account the need for alignment and safety when moving through narrow aisles. Reverse slowly regardless of direction is not a recommended practice either, as it could lead to collisions or damage to nearby goods if the stacker is not aligned correctly.
