Maintaining an articulating boom lift is essential for ensuring its longevity, safety and optimal performance. Regular check-ups should include inspecting the hydraulic system, electrical components and control operations to detect malfunctions early. Lubricating moving parts is critical for smooth operation and to prevent wear and tear. Tires and outriggers should also be checked frequently for signs of wear or damage. Lastly, always adhere to the manufacturer's recommended maintenance schedule and guidelines, and ensure certified professionals carry out any repairs. United Rentals offers equipment service and inspection of owned equipment to keep your fleet maintained.

Articulating boom lifts — sometimes referred to as knuckle booms — use arms with sections separated by joints or “knuckles.” These lifts are ideal for tighter spaces that might be difficult to reach.

Specific instructions depend on your machine and specific task. Always inspect the machine, review the owner’s manual and ensure the operator is properly trained and certified before operating a knuckle boom lift.
