Crane Inspection and Certification All truck-mounted cranes require an annual safety inspection. Multi Engineering offers a certification-grade inspection and repair service carried out by trained and experienced personnel. We offer a full maintenance and repair service for all brands of knuckle boom cranes. Crane Inspection Service At Multi Engineering our crane inspection is a comprehensive, hands-on service and takes around six hours. This is far more extensive than the typical torch and hammer testing. Our inspection includes the following:
  • We thoroughly clean and inspect the crane structure, hydraulic systems and controls.
  • We check all bolts and fasteners are tight with a spanner or torque wrench for critical components.
  • We check the tightness and condition of the bolts connecting the sub-frame to the truck chassis, and also the main bolts connecting the crane to the sub-frame.
  • The truck chassis, sub frame and full crane structure are all checked for fatigue cracking, distortion and damage.
  • The condition of the paint is assessed, and areas of corrosion indicated on the test as a fail and repair, or noted for the next annual test..
  • We check all hoses and hydraulic fittings for leaks, cracking or damage.
  • The hydraulic oil tank is checked for damage or leaks and hydraulic fluid checked for condition, correct level and water content.
  • PTO and PTO pump are checked for leaks, excess noise or damage.
  • Hydraulic cylinders are checked for damage and leaks.
  • Stabilizer legs are checked for correct operation, damage, wear and that fasteners are all tight.
  • We check all crane stickers, decals, load charts, range diagrams for existence, legibility and condition.
  • All cranes have their crane hook or hook block tested or replaced with a tested hook from our tested hook pool.
  • The crane is worked throughout its operating range, and pins and bushes, pivot points and slides and guides are all checked for condition and wear.
  • We check the maximum lifting capacity of the crane as well as any safety systems to limit loads or to indicate overloads.
  • We conduct a full load test for creep or dropping.
  • If any areas are requiring repair or adjustment, we will quote for repair and arrange a new booking with you.
  • The reworked areas are retested and if OK, a test report or certificate is issued.
  • A full greasing and filter change is done and the crane is ready for work.
A copy of the check sheet, full details of any repairs and a hook test certificate are available.
