[david merrill]

For those interested in the nitty-gritty, here are some references for cargo securement and tiedown relating to road transport of heavy equipment.

Canadian and U.S. highway safety agencies, transportation research organizations and manufacturers of
cargo transport vehicles and equipment have been thrashing this out over the past two decades - pursuant to NAFTA. Canadian research organizations undertook the lead role in performing the underlying technical studies.

The current Canadian version of the resulting standard is:

Note the G-load guidance in Section 5(1) on page 10-13. For example, if the transported load were a milling machine weighing 2000 pounds its specified forward design load on its tiedown restraints would be 0.8 x 2000 lbs = 1600 lbs, rearward load 0.5 x 2000 lbs = 1000 lbs, and sideways load 0.5 x 2000 lbs. Note also the tie(chain, strap, rope, etc) working load limits in Part 4 starting on page 10-46.
