A core interactive course of 19 interactions and 7 validated competencies where learners read real load charts and work radius, boom angle, configuration, and weight estimation. They learn to confirm a lift is within capacity by the numbers before the load leaves the ground.
Load-chart and load-weight awareness for everyone involved in planning and making crane lifts — operators, riggers, lift directors and supervisors — in construction, steel erection, industrial maintenance, and general industry. Aligned with the Manitoba WSH Act (C.C.S.M. c. W210, including the s.43 right to refuse dangerous work), WSH Regulation MR 217/2006 (cranes and hoists), and CSA Z150 (mobile cranes — load charts and rated capacity).
Give everyone who plans or makes crane lifts the literacy to answer the two questions every lift depends on — what does the load actually weigh, and what can the crane actually lift in this exact configuration — so that no lift ever proceeds on a headline…

Who this course is for
Crane and lift operators, riggers, and workers who plan or participate in lifts and must interpret load-chart capacity.
Crane operators reading and working to the load chart
Riggers and lift directors planning lifts and confirming capacity
Supervisors and superintendents who approve or direct crane lifts
Signal persons and crew who need to understand why a lift is within (or over) capacity
What you will learn
Determine the actual weight of a load by reliable means — data plate or stamped weight, shipping/mill documents, calculating from dimensions × material density, or a load cell — and never accept "about"
Explain that a crane's rated capacity is not a single number: it changes with radius, boom length, configuration, outriggers and quadrant of operation
Distinguish the headline (rated) tonnage from the real capacity for the actual pick, and understand that capacity shrinks as the load moves out to a larger radius
Apply gross vs net capacity — deduct the hook block, hook, jib and all rigging to find the net capacity available for the load
Account for the dynamic reductions and the safety margin — wind, swing, side-load and soft ground reduce real capacity, so a lift is never rigged to 100% of the chart

The Chart Is Not One Number — The load chart as a table, not a single number — capacity changes with radius (how far the load is from the crane's centre), boom length…
Gross, Net, and the Real Margin — Gross vs net capacity — the chart figure is GROSS and must carry everything on the hook first: deduct the hook block, hook, jib and all…
Reading the Whole Lift — Putting it together — the pre-lift capacity check as two honest numbers meeting: the verified load weight, and the crane's net capacity for…
Laws and standards covered
Manitoba Workplace Safety and Health Act (C.C.S.M. c. W210)
Manitoba WSH Regulation MR 217/2006
CSA Z150 (Mobile Cranes)

Certificate and renewal
Passing the final test issues a QR-verified certificate, valid for one year. Orientra’s standard is for training to be reviewed at least annually and whenever the equipment, load charts or lift conditions change.
