A drop deck trailer increases versatility and allows you to haul more—especially loads with special requirements. High-performing, lightweight aluminum drop deck trailers from Benson give you low-cost, low-maintenance miles whether you haul regionally or cross-country.

Our nationwide network of highly trained dealers customizes our aluminum drop deck trailers to meet your specific needs. With engineering and features designed to increase safety, decrease weight and increase load capacity, our trailers give you results and peace of mind.

Superior Main Beam. Lower Maintenance.
The two-piece, welded main beam design eliminates
the need for mechanical fasteners by welding on the
neutral axis of the main beam where bending stress
is minimal. Unlike bolted designs, this main beam
doesn’t have fasteners, which eventually loosen,
requiring additional maintenance over its lifetime.

Less Weight. More Freight.
Floor crossmembers weld to the main beam, side rail,
and floor to form a super stiff structure, eliminating the
need for knee braces for a lighter weight trailer and
less maintenance.

Greater Flexibility. More Loaded Miles.
The Lock-Rite™ multi-position tie down system
offers flexibility to either tie down narrow loads to
the center of the trailer or to the outside siderails.
This patent-pending design also allows the use of
either straps or chains to secure loads.

Better Highway Visibility.
The enhanced visibility lighting system offers three
stop/tail/turn lights and five dual-function side
marker lights. The side marker lights also function
as turn signals for improved motorist visibility. In
addition, the one-piece, tubular bumper includes
an extruded grip surface.
