Tower Crane Inspection & Certification

Mast, foundation and tie-ins

The mast carries the entire crane load down to the foundation, so its sections, the connection bolts or pins between them, and the base anchoring are safety critical. We inspect these connections and, where the crane is tied into the structure, examine the tie-in collars and their fixings, since these anchor the tall mast against wind and lifting loads.

Tower cranes remain in one position for long periods and are exposed to weather, so corrosion and bolt condition receive careful attention.

Slew, jib and hoist

The slewing unit, slew ring and counter-jib with its counterweight are inspected as the rotating heart of the crane, and the jib structure, trolley or luffing mechanism is examined for cracking, distortion and wear. The hoist ropes, drums, brakes and hook block are checked as the direct link to the load, with non-destructive testing applied where duty and age warrant.

Safety devices and certification

Tower cranes rely on load-moment limiters, hoist and trolley limits, anti-collision systems where multiple cranes operate, and wind monitoring. We function-test these safeguards and document their operation. Periodic inspection and a major inspection apply under AS 2550.4, and our report records the structural, mechanical and safety-device findings and the certification outcome.
