Plan the load path and maintain control during lifting
Identify the real load
A reinforcing bundle or prefabricated cage needs a lift-specific plan. Establish weight, centre of gravity, geometry, stability, and suitable pick points. Include the relevant below-hook gear in the suspended load calculation. Shipping bands do not become rated lifting devices merely because they hold bars together in transit. A tied cage may not act like a rigid lifting frame, so its temporary lifting forces and bracing require an appropriate approved basis. Consider the route, landing area, personnel, and adjacent work before connecting the load.
Interpret capacity correctly
Use verifiable rigging identification and manufacturer ratings for the actual hitch and angle. An angle must have a stated reference: an angle to horizontal is not the same numerical geometry as an angle to vertical. In a symmetric two-leg system, each vertical component supports half the weight, but the actual leg tension increases as the legs flatten. Ideal calculations are learning tools, not a replacement for rated assemblies, dynamics, unequal sharing, and the approved lift. Four legs do not guarantee exact equal-quarter loading. Protect slings from damaging edges and keep connectors loaded as intended.
Test and communicate
Place the hook appropriately relative to the centre of gravity and conduct the specified controlled initial lift. If the load tilts or shifts unexpectedly, lower it safely for reassessment instead of using speed or workers' hands to force stability. Use the agreed signaling system and designated roles, recognizing emergency stops. Loss of communication calls for the specified controlled stop, not indefinite continuation of the last command. A tagline can help orientation from a safe position, but wrapping it around the body or standing in a crushing zone creates additional hazards.
Land and release safely
Prepare stable dunnage and sufficient clearance to retrieve rigging without reaching beneath the load. Release the gear only when support and required temporary restraint are established. Check ground conditions, crane configuration, operating radius, weather limits, overhead electrical hazards, and interacting work throughout the sequence. A changed radius or site condition can invalidate an earlier assumption. Crane mobilization and demobilization also depend on the specific manufacturer's sequence and competent personnel; familiarity with another machine is not a substitute for the current instructions.
