AHU and mechanical plant installation: energy sources and direct controls

Installing air handling units and plant involves very heavy modules, machine lifting into tight plant rooms and power tool work around the unit.

High-energy check

AHU modules and plant sections exceed the 1500 J trigger whenever they are lifted clear of the floor, and skated moves carry serious crush and tip-over exposure at any speed. Keep every person out from under and beside the moving unit.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

The lifting or skating plan matches the module mass.
The route and floor loading are checked before the move.
No person is under or beside the module while it moves.
The module is stable and supported before rigging is removed.
Hands are kept out of gaps during final positioning.
Stop if the module moves in an unplanned direction.

For your SPA or pre-start

State the module mass, the lifting or skating method, the route and floor loading check and the exclusion around the movement.
