When the stacker moves straight between rows of goods, what operation should be performed to avoid collisions?

When the stacker is moving straight between rows of goods, it is crucial to avoid lifting the cargo too high while in motion. Keeping the load at a lower height helps maintain stability and visibility, which significantly reduces the risk of collisions with other goods or obstacles. High lifts can obstruct the operator's view and make it challenging to navigate carefully, increasing the likelihood of accidents.

Additionally, operating with the load raised can lead to instability, making the stacker more prone to tipping over or causing the load to fall. This practice enhances safety and ensures a smoother operation while maneuvering within confined spaces. Lowering the lift height while driving through aisles is a standard safety protocol in forklift operation and is designed to protect both the operator and the merchandise.

The other options, although they may seem plausible, do not promote safe navigation practices. For instance, turning sharply or accelerating to pass quickly can lead to a loss of control and potential accidents. Lifting the cargo to ruin its position is counterproductive and dangerous, as it compromises both load integrity and visibility.
