The 55-ton (50 t) spread-axle, low-deck trailer (55SA-LD) from Talbert Manufacturing features an 18-in. (46 cm) deck height and an E1Nitro so it can run with three axles, four axles close-coupled or as a 3+1 spread-axle. The trailer is an optimal solution for haulers who need the flexibility of a low deck height and the flexibility to run a variety of configurations, according to the manufacturer.
The 55SA-LD is an East Coast trailer whose height is 2 in. (5 cm) lower than Talbert's standard 55SA unit. The extra 2 in. provides an advantage for haulers who need to haul heavy and oversized equipment under bridges or through tunnels with low clearance rather than making trips around. In addition, the lower deck height equates to additional load opportunities.
The standard Talbert 55SA-LD features a non-ground bearing hydraulic gooseneck design with a 108-in. (274 cm) swing radius. The trailer's 24-in. (61 cm) flip gooseneck extension results in a 132-in. (355 cm) swing radius that allows haulers to transfer additional load from the drive axles to the steer axle of their tractors. The E1Nitro also allows companies to expand their service regions into states that require the fourth axle to be at least 14 ft. 1 in. (4.3 m) from the third axle.
The E1Nitro makes the 14-ft. 1-in. spread between the third and fourth axles possible. The system articulates left and right and uses nitrogen to equalize the up and down movement to provide proportionate weight distribution in each axle grouping.
