Sling angles and leg tension: why a flatter sling carries more
How the angle of a multi-leg sling changes the tension in each leg, how the uniform load method rates multi-leg slings, and what changes when the legs are unequal.
Guide · 6 minGround bearing pressure under crane outriggers and how mats help
Outrigger loads, bearing pressure, presumptive allowable values and what a timber mat can and cannot do.
Guide · 5 minForklift capacity at the actual load centre
Why the plate capacity is not the capacity you have, and how load centre, lift height and several loads on the forks change it.
Guide · 6 minLoad securing for road transport: the basics of EN 12195-1
The forces a load must be restrained against, tie-down versus direct lashing, and how to read a lashing label.
Guide · 5 minSide boom pipelayers: pipe weight, work radius and set-back
