A wall cage is ready to lift but not ready to stand
A prefabricated wall cage is lying on dunnage beside its foundation. The crew has completed the ordinary intersection ties, but the lift points and temporary standing restraint have not been verified against a lifting plan. A pair of shipping bands remains around part of the cage. The crane can reach the destination, although its final radius will be greater than the radius at the pickup position. Workers have prepared a narrow landing area, and one suggests holding the cage upright while the rigging is released. The rigger must consider the cage's construction-stage behavior, the actual operating configuration, the landing supports, and the exclusion arrangements rather than treating a tied assembly as a rigid rated lifting frame.
1. What information is needed before the lift?
Read the worked answer
Verify cage weight, centre of gravity, structural behavior, approved pick points, temporary restraint, rigging ratings, sling geometry, route, and the crane capacity at the relevant configurations. Shipping bands and ordinary ties are not assumed to be rated lifting points.
2. When can the rigging be released after landing?
Read the worked answer
Only after the cage has the required stable support and temporary restraint, with the landing condition checked. Workers should not substitute their bodies for bracing. Maintain the agreed exclusion and communication controls, and provide a safe way to disconnect and retrieve rigging.
