7 x 16 Lamar DT 21K Dump Trailer – Ready To Work!

7 Gauge Floor, Telescopic

The Lamar DT (Telescopic) dump trailer is a commercial-grade workhorse known for its high dumping angle and heavy-duty frame. While specific configurations can vary by dealer, the "DT" model line is defined by several high-end standard components.

KEY STANDARD FEATURES 3-Stage Telescopic HoistUnlike standard scissor lifts, the DT model features a heavy-duty 3-stage telescopic cylinder. This front-mounted lift provides a more efficient leverage point, allowing for a steeper dumping angle (typically around 47°) and reduced strain on the hydraulic system when lifting heavy loads.

7-Gauge Steel FloorWhile many competitors use 10-gauge or 12-gauge steel, the Lamar DT comes standard with a 7-gauge floor. This thicker steel provides superior durability against denting and warping when dropping heavy debris like concrete, large rocks, or machinery.

12" On-Center CrossmembersThe structural integrity of the bed is reinforced with 3" channel crossmembers spaced every 12 inches. This tight spacing ensures the floor remains flat and supported under extreme point-loading conditions, such as loading a skid steer with narrow tracks.

8" I-Beam FrameThe backbone of the trailer is a continuous 8" x 13lb I-beam frame. This one-piece design is more resistant to "twisting" under uneven loads compared to traditional channel frames, making it ideal for the high-stress environments of construction and demolition.

3-Way Combo Gate The "Spreader Gate" system is a versatile standard feature that allows for three different operations:

• Barn Doors: For dumping large debris or loading equipment.
• Spreader Mode: For metered spreading of gravel or topsoil.
• Tailgate: For traditional fold-down use.

Cold Weather Wiring HarnessTo ensure reliability in all climates, the DT is equipped with an Arctic-rated (-65°F) wiring harness. This fully sealed, modular system stays flexible in freezing temperatures, preventing the cracking and electrical shorts common with standard plastic-coated wiring.

Integrated Charging & Power SystemThe hydraulic system is powered by a 12V deep cycle battery housed in a locking front toolbox. It includes a 5-Amp 110V trickle charger as standard, allowing you to simply plug the trailer into a wall outlet at the end of the day to keep the battery topped off for the next morning.

PERFECT FOR Demolition & Concrete RemovalStandard dump trailers often suffer from "floor oil-canning" (denting and warping) when heavy chunks of concrete or rebar are dropped into them. The 7-gauge steel floor is thick enough to handle high-impact debris that would ruin a thinner 10-gauge or 12-gauge bed.

Heavy Aggregate SpreadingIf your work involves hauling and spreading large loads of #2 crushed stone, rip-rap, or heavy wet clay, the telescopic cylinder is your best friend.

• Efficiency: Front-mounted cylinders require less hydraulic pressure to initiate a lift.
• Safety: It provides a very stable, steep dump angle that ensures "sticky" material slides out completely rather than getting stuck and risking a tip-over.

Equipment TransportationBecause of the 8" I-beam frame and 12" on-center crossmembers, this trailer doubles as a reliable equipment hauler. It is perfect for transporting:

• Skid steers and compact track loaders.
• Mini-excavators.
• Heavy attachments (like hydraulic hammers or augers).

High-Frequency Commercial UseIf you are dumping 10–15 times a day, a scissor lift can generate significant heat and wear. The telescopic design is more mechanically efficient, meaning less strain on the pump and battery over long shifts. It’s built for the contractor who uses the dump function as a primary part of their hourly workflow, not just once a week.

WHY CHOOSE THE LAMAR DT DUMP OVER THE COMPETITION Choosing the Lamar DT over other big-name competitors usually comes down to three factors: unmatched floor durability, mechanical efficiency, and superior finishing.

While many brands offer a "heavy-duty" line, Lamar includes several features as standard that others often list as paid upgrades.

The "7-Gauge" StandardIn the trailer world, "standard" is usually 10-gauge steel. To get a 7-gauge floor (which is roughly 30% thicker), you typically have to place a custom order with other brands.

• The Benefit: It prevents the "washboard" effect—where the floor ripples between the crossmembers after dropping heavy rocks or concrete. A Lamar DT floor stays flat longer, which means easier dumping and better resale value.

Efficiency of the Front-Mount Telescopic LiftMost mass-market dump trailers use a scissor lift. While strong, a scissor lift is under the most stress at the very beginning of the cycle when it’s trying to "push up" from a flat position.

• The Lamar Advantage: The DT’s telescopic cylinder is
