A truck-mounted boom crane where the boom, wire rope, outriggers, and load-moment system carry the same safety weight as a mobile crane.
National Crane boom trucks mount a hydraulic crane on a commercial chassis. The crane inspection mirrors any mobile crane — wire rope, LMI, outriggers, and certification — with the truck chassis and PTO added.
Boom wear and rope condition govern safe lifting.
CHECK Inspect the boom and wire rope for wear, broken wires, and corrosion.
Drift indicates failing valves.
CHECK Check boom and outrigger drift under load.
Outriggers and the load-moment system are safety-critical.
CHECK Set up and verify the LMI and anti-two-block.
Swing and winch/brake wear are costly.
CHECK Check swing play and test the winch and brake.
The truck, PTO, and certification status matter.
CHECK Inspect the chassis and PTO and verify a current crane certification.
