Flow Boy
a specialized belt trailer (or self-unloading trailer). This style of trailer moves massive amounts of asphalt or other commodities without ever leaving the cab of the truck. The trailer attaches to a truck / tractor like other semi-trailers. Unlike dump trailers, the bed of the flow boy never raises, making it a safer option when working around power lines, bridges, and other overhead obstructions. They are also beneficial when paving super-elevated road or race tracks, with steep banking. SePi has several live bottom Flow Boy trailers in our fleet.
Steel Bed Multi-Axle Dump Trucks
Used for hauling everything an aluminum bed will haul but has more versatility for larger dump rock and demolition materials or concrete chunks. SePi has many steel bed dump trucks in our fleet.
Drop Deck
A specialized trailer with just one drop in the deck, right after it connects to the truck. It still sits low to the ground but not as low as a lowboy trailer. The deck itself is longer and can accommodate longer items that might not otherwise be able to be hauled on a lowboy. There are ramps on the back of this style of trailer that allows you to drive your equipment right up on the trailer, unlike a lowboy / RGN. SePi has many drop deck trailers in our fleet.
Aluminum Multi-Axle Dump Trucks / Dump Trailers
Used for hauling dirt, asphalt, aggregates, and other materials. SePi has several aluminum trucks / dump trailers in our fleet.
Lowboy / RGN (removable gooseneck)
A specialized trailer that has two drops in the deck; one right after the gooseneck (that attaches to the truck) and one before the wheels on the trailer (which are at the very back of the trailer. This trailer allows us to haul taller items and still maintain the legal hauling height of 13’6", since it sits very close to the ground. Equipment is loaded by detaching from the truck and driving the equipment onto the trailer then reattaching it. SePi's Lowboy/RGN fleet has 25’ "in the well".
Flatbed
A standard trailer with no sides or roof which allows for easy loading and unloading with cranes or forklifts, depending on the load. This style trailer sits about 3-1/2 feet off the ground and are customarily 48’ or 53’ long. SePi has many 48’ flatbed trailers in our fleet.
