With the price of new trailers taken into consideration, it has become very economical to convert trailers with older axle configurations to the new Ontario “SPIF” Regulations. There are many things to consider when contemplating this procedure, most importantly, overall tank condition. With impending weight restrictions on older axle configurations, converting these trailers to conform to the new regulations, allows carriers to transport cargo at the maximum weight allowances which on a cost to transport basis, maximizes efficiency and profitability.
When this unit arrived it had spoke wheels, carbon steel frame, tandem rear axles and spring suspension with dual forward lift axles, insulation with a stainless jacket and an older style bumper and older style lights. The trailer came into the shop where it was stripped down to the rings and barrel. New side supports were fabricated and welded in place in preparation for the stainless steel frame and sub frame. In the mean time, technical drawings and blueprints were sent to our Engineer on staff, to work out the axle locations relative to the barrel, for the trailer to load equalize. Once ascertained, construction begins on the bogie.
