The hand signal that represents Trolley Travel is characterized by a palm-up position, fingers closed, and the thumb pointing in the direction of motion. This motion is often accompanied by a jerking action of the hand horizontally. This specific signal is designed to clearly communicate to the crane operator the necessity to move the trolley—a component that allows the hoist to move along the beam—horizontally across the overhead structure.

Using a palm-up gesture ensures that the signal is visible and distinct from other signals, helping to maintain clarity and safety in communication during crane operations. This is crucial in a work environment where multiple signals may be in play, as it reduces the likelihood of misinterpretation that could lead to accidents.

The other choices do not appropriately represent Trolley Travel according to industry-standard signaling practices. For example, the palm down with fingers extended might indicate a different movement or action, while pointing with one finger or raising both hands above the head conveys other commands and could lead to confusion if used in the context of signaling for trolley movement.
