Structure and movement
A double mast arrangement uses a paired mast structure to define the platform's vertical path. The platform, paired masts, base and setup supports have different measurement boundaries. Use a labelled sketch so a platform dimension cannot be mistaken for the complete equipment width.
Describe how the equipment reaches the work area, where it is set up and where the platform must be positioned for the task. The folded movement envelope, support footprint and raised arrangement should be considered separately, including obstructions beside and above the equipment.
