The Horizon LZ7 Series Low-Profile Dump Trailer (14,000 lb. GVWR) with Telescopic Hoist is an elite, commercial-grade dumping platform. Engineered for severe-duty contractors, roofing crews, and heavy excavation operators, this specialized LZ7 variant replaces the traditional under-bed scissor lift with a high-efficiency front-mount multi-stage telescopic hydraulic cylinder.

By shifting to a telescopic hoist system, this trailer maximizes lifting leverage, reduces overall strain on the hydraulic pump, and lowers dry weight—all while maintaining the low center of gravity and low deck height that defines Horizon's LZ7 series.

CORE FEATURES OF THE HORIZON LZ7 14K TELESCOPIC DUMP

Front-Mounted Multi-Stage Telescopic Hydraulic Hoist The defining mechanical feature is a heavy-duty, multi-stage hydraulic ram mounted directly to the front headboard of the dump body.

• The Benefit: Works like a commercial class-8 dump truck. Pushing from the very front of the box gives the hydraulic fluid maximum physics leverage over the load, requiring lower hydraulic system pressure to lift heavy, sticky loads. It provides a steep 50-plus degree dump angle that clears wet clay, asphalt, and roofing scrap instantly with zero tail-heavy frame twisting.

Low-Profile 8" I-Beam Main Frame & Integrated Tongue The structural backbone features a continuous 8-inch structural I-beam main frame and wrap-around tongue, backed by 3-inch channel crossmembers spaced on tight 12-inch to 16-inch centers.

• The Benefit: Placing the dump bed lower inside the frame rails creates an ultra-low center of gravity for exceptional highway stability. Deleting the bulky under-bed scissor mechanism allows the bed to sit even cleaner on the chassis, keeping the rear equipment loading height as low as possible.

Heavy-Duty 10-Gauge Steel Floor & 24" Sidewalls The main box is fabricated using a continuous, solid 10-gauge steel floor plate paired with 24-inch (2-foot) 10-gauge structural steel sidewalls with integrated board brackets.

• The Benefit: Delivers high puncture and impact resistance against falling concrete, skid steer buckets, and boulders. The top rim is capped with a thick structural tube rail to prevent wall bowing, while built-in stake pockets let you add wood planks to extend wall height.

3-Way Combo Rear Spreader Gate & Slide-In Equipment Ramps The rear tail features a heavy-duty 3-way combination gate (dump doors, spreader gate, and pick-up tailgate) paired with under-bed slide-in steel ramps.

• The Benefit: Allows you to metered-spread gravel down a driveway, open full barn doors for bulk dumping, or pin the gate open and pull out the heavy-duty rear ramps to load skid steers, mini-excavators, or tractors directly into the bed.

Tandem 7,000 lb. Electric Brake Axles (14,000 lb. GVWR) The running gear features tandem 7,000 lb. Dexter electric brake axles equipped with heavy slipper spring suspension.

• The Benefit: Delivers a standard 14,000 lb. GVWR, granting a true net legal payload capacity of up to ~9,400 to 9,800 lbs. (benefiting from the lower dry weight of the telescopic setup). Integrated EZ-Lube hubs make spindle bearing maintenance quick and simple.

Integrated Tarp Kit & Lockable Front Tongue Toolbox Comes factory-equipped with a heavy-duty mesh tarp assembly and a large steel tongue toolbox.

• The Benefit: The built-in roller tarp system allows you to cover loose gravel, sand, or debris in seconds to remain D.O.T. compliant on the highway. The front toolbox safely houses the hydraulic power unit, deep-cycle marine battery, corded remote, and onboard trickle charger under lock and key.

6-Stage Baked Powder Coat Finish in Custom Colors The entire steel frame undergoes an aggressive steel grit blast prep before receiving a durable, heat-cured powder coat armor.

• The Benefit: Seals the steel chassis against stone impact, gravel abrasion, road salt, and rust in finishes like Midnight Black, Ash Grey, Military Green, Desert Tan, and True Red.

THE HORIZON LZ7 14K TELESCOPIC QUICK SPECS

• GVWR: 14,000 lbs.

• Estimated Net Payload: ~9,400 lbs to 9,800 lbs depending on bed size (12', 14', or 16').

• Bed Dimensions: 83" Inside Width x 12 FT, 14 FT, or 16 FT Lengths.

• Side Wall Height: 24 Inches (2 Feet) Standard with 10-Gauge Steel.

• Hoist System: Front-Mount Multi-Stage Telescopic Hydraulic Cylinder.

• Running Gear: 2 - 7,000 lb. Dexter Electric Brake Axles.

• Tires: ST235/80R16 10-Ply Radial Tires on Heavy-Duty 8-Lug Steel Wheels.

WHY THE TELESCOPIC HOIST OVER A SCISSOR HOIST?

• Superior Mechanical Advantage: Scissor hoists push upward from the middle-rear of the bed under extreme hydraulic PSI. A front-mount telescopic cylinder pushes from the very front, using maximum leverage to lift max-capacity loads easier while reducing strain on the battery and pump.

• Higher Dump Angle: Telescopic cylinders extend higher than scissor linkages, producing a steeper dump angle (50°+) that forces sticky, wet, or frozen materials to slide out clean without shaking or dumping in stages.

• Reduced Maintenance & Fewer Moving Parts: A multi-stage cylinder eliminates the complex mechanical scissor arms, bushings, and multiple pivot points that wear out, squeak, and require grease over years of hard job-site use.
