Wolf Trailer Company is the driving force behind the latest innovation in the heavy truck industry.
The Vernon-based business recently announced the Commercial Vehicle Safety and Enforcement Branch (CVSE) of the B.C. Ministry of Transportation and Infrastructure has granted approval for tridem axle pony trailers to operate at the maximum allowable weight of 24 tonnes, provided they are connected to the towing truck by a roll-coupling hitch system.
With this technology in place, carriers will realize a three-ton increase in trailer productivity, and will enjoy better heavy truck safety through improved trailer stability.
For the public, the result is improved road safety, reduced traffic congestion, decreased transportation costs and reductions in fuel consumption and exhaust emissions.
Wolf Trailers has spent the last four years and more than $300,000 in a collaborative research and development program to establish the benefits of this innovative hitch system. During that time, they worked closely with CVSE staff and other experts in the field of heavy vehicle dynamics and testing, such as FP Innovations and Innovative Vehicle Testing Ltd.
When compared to pintle hitches, roll-coupling systems can increase the roll stability safety margin of fully loaded tridem pony trailers by up to 20 per cent to meet or exceed minimum national safety performance standards.
Roll-coupling enables heavy trucks and trailers to maintain maximum productivity and comply with prescribed safety standards.
Wolf Trailers thanked Jack, Patti and Rick Wood (Woody’s Sand and Gravel), Bob Mohr and Dwayne Douglas (Mormak Equipment), Pat Young (Roga Contracting), Jim Knight (Tolko) and Barry Bertolli (CVSE) for their support.
Wolf Trailers is now exploring opportunities elsewhere in Canada, U.S., New Zealand and Australia to enable pony trailers, full trailers and road trains to comply with safety standards.
The company is producing roll-coupling hardware in Vernon for use on pony trailers in B.C. and trailers behind tri-drive trucks in Saskatchewan.
