• Additional moving parts that may require more maintenance
• Steeper learning curve for operators to maximize effectiveness

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

Exhaust Configurations: Consider the types of vehicles you service and their exhaust system designs.

Questions to ask:

• Do you primarily work with consistent vehicle types or a diverse range?
• Are you dealing with standard horizontal exhaust pipes or vertical stacks?
• How much variation exists in where vehicles are positioned during service?

Recommendation: For shops focusing primarily on similar vehicles with predictable exhaust positions, pivoting arms often work well. Facilities servicing diverse vehicle types from passenger cars to heavy equipment will benefit from articulating arms' adaptability.

3. Required Reach and Coverage

Extension Needs: Determine the maximum distance your boom arm needs to extend and the range of motion required.

Questions to ask:

• What is the furthest point that needs exhaust extraction in your workspace?
• Do you need to cover multiple work areas with a single boom arm?
• How precisely do you need to position the extraction point?

Recommendation: For straightforward, direct extension needs within 13 feet, pivoting arms may be ideal. For greater reach (up to 20 feet) or complex positioning requirements, articulating arms provide superior coverage.

4. Budget Considerations
