Key Decision Factors: Making the Right Choice When deciding between pivoting and articulating boom arms, consider these critical factors:

1. Workspace Configuration

Facility Layout: Measure your available wall space, ceiling height, and the distance to the typical work areas. Map out any permanent obstacles like support columns, existing equipment, or storage areas.

Questions to ask:

How many bays or work areas need coverage?
Are there overhead cranes or other obstacles that the boom arm needs to work around?
Is your facility layout likely to change frequently?

Recommendation: For open, obstacle-free spaces with consistent workflows, pivoting arms may be sufficient. For complex layouts with multiple obstacles or changing configurations, articulating arms offer valuable flexibility.

2. Vehicle Types and Diversity
