1Wind Load and the Double-Stack at the Waterfront Slot
You are asked to lift a 40 ft container from ground level onto a stack that is already two high, making the target the third tier. The load chart for your machine at the required boom/extension geometry and the measured radius of 9.5 m shows a rated capacity of 8.2 t for a spreader-only configuration.

You are setting up in a container yard on a compacted gravel hardstand. The yard manager points to a painted rectangle and says 'this is where the reach stackers always work.' You notice the surface there is rutted and one corner of the rectangle sits over a patch of darker, softer-looking ground near a recently backfilled drainage trench.

You are working a busy container yard with a single access lane between two rows of stacked containers. The lane is 7 m wide; your reach stacker is 4.1 m wide with the spreader retracted and you need to swing the boom to place containers into the second row, which means the rear of the machine sweeps toward the access lane.

At the start of the shift you complete the pre-start inspection. You find: (1) the left rear tyre has a deep sidewall cut about 40 mm long, with the cord not visibly exposed but the cut is open; (2) the boom lift cylinder has a light film of oil around the gland, with no drips on the ground; (3) the reverse alarm sounds intermittently when you test it, working about seven times out of ten; (4) the load chart placard in the cab is faded but the figures are still legible.
