Grade T (80) and Grade V (100) must have period inspections and the Australian Standard AS3775 includes a guide on how often these inspections should take place. The guide is based on lift cycles (Per week), with 1 lift cycle equal to lifting and lowering a load once.
Number of Lift Cycles (per week)
1 to 5 = 12 monthly periodic inspection
6 to 25 = 6 monthly periodic inspections
26 to 200 = 3 monthly periodic inspections
201 plus = monthly inspections
