What must occur when extending the outriggers?

When extending the outriggers, it is essential to make visual contact or post a signalperson because this ensures that the crane operator has an accurate understanding of the surroundings and can safely position the outriggers without causing hazards. The presence of a signalperson can help guide the operator by communicating vital information about the area, potential obstructions, and ensuring that the crane is set up on stable ground. This practice enhances safety by ensuring that all maneuvers can be performed with clear visibility and assistance, reducing the risk of accidents during this critical setup phase.

While relying on voice commands may seem convenient, it can lead to misunderstandings, especially in noisy environments. Following a pre-written checklist is useful for ensuring proper safety protocols overall but does not provide real-time, situational awareness. Using a crane feature indicator can offer technical data about the crane's operation but does not replace the need for effective visual communication or oversight during the physical positioning of the outriggers.
