Trigg Industries has been installing its over height early warning system in Western Canada with eight installations in Alberta four years ago. The Trigg over height vehicle detection system activates when the truck breaks the beam (A), and a sign (B) directs the truck to divert to exit (C). While container loads are the same height, construction equipment and loads related to construction are growing.
“The equipment is getting bigger and the infrastructure is the issue,” he said as large projects currently near completion. “What we are seeing is the big moves because of the decommissioning of Site C and the Coastal pipeline is almost done. The big stuff is winding down and equipment is being demobilized and relocated.” Earle said highway construction needs to be modernized to accommodate today’s larger loads and over height vehicle detection systems are available that can warn a driver his load won’t fit under a structure. But, these systems need to be combined with a highway exit design that can accommodate trucks hauling over height loads
