Critical Lift

A Definition of Critical Lift

A “critical lift” means:
(a) a lift by a mobile crane or boom truck that exceeds 90% of its rated capacity while it is lifting the load at a load radius of more than 50% of its maximum permitted load radius, taking into account its position and configuration during the lift,

(b) a tandem lift if the load on any one crane, hoist or other piece of powered lifting equipment exceeds 75% of the rated capacity of that crane, hoist or other piece of powered lifting equipment,

(c) a tandem lift involving the simultaneous use of more than two cranes, hoists or other pieces of powered lifting equipment,

(d) a lift of a person in a work platform suspended from or attached to a crane or hoist,

(e) a lift in which the centre of gravity of the load changes during the lift,

(f) a lift in which the length of one or more sling legs changes during a lift,

(g) a lift by a crane, boom truck or hoist, supported on a floating base, that exceeds 90% of rated capacity for the lifting system,

(h) a lift of a load over or between energized high voltage electrical conductors, or
