BC hikes lowbed, heavy-haul axle weight by 1,000 kg

VICTORIA — B.C.’s Ministry of Transportation and Infrastructure has increased the permittable weight on axle groups on lowbed trailers and jeeps in “heavy haul” applications.

In vehicle configurations that include a tandem or tridem drive truck tractor, a tridem jeep and tridem lowbed semi-trailer (with axle spreads of minimum 2.4 m and maximum 3.1 m), and a tandem booster, the permittable weight allowance is up from 27,000 to 28,000 kg on each of the jeep and lowbed tridem axle groups.

The existing permittable limit of 29,000 kg on the lowbed tridem axle group when connected with a single axle booster will remain unchanged, the ministry stated in an advisory to industry.

Tridem lowbed semi-trailers manufactured before December 31, 2010 with tridem axle spreads of minimum 3.0 m and maximum 3.7 m will be grandfathered and allowed the same increases described above.
