Overview
The NestaFlex 376PL is the industry’s leading expandable gravity conveyor for outbound trailer loading. While the 376AL/FL is designed for general-purpose heavy-duty dock work, the 376PL is engineered specifically as a truck loader system — purpose-built to integrate with fixed feed conveyors and deliver smooth, continuous package flow into trailers at distribution center speeds.
What makes the 376PL unique is its perpendicular leg design. The leg brackets are engineered to keep the legs vertical relative to the floor whether the conveyor is fully extended into a deep trailer or contracted for the next load. This keeps the swivel casters flat on the floor at every extension point, giving operators maximum maneuverability and stable rolling performance — a critical advantage in high-cycle outbound operations where the conveyor is pushed in and pulled out of trailers hundreds of times a day.
Features and Benefits
The 376PL shares the heavy-duty construction DNA of the 376 series — 376 lb/ft capacity, 7-gauge steel side links, shoulder bolts with Loctite, and steel locking nuts — then adds truck-loader-specific features that set it apart.
- Perpendicular fixed-height legs remain vertical at all extension points for flat caster contact and stable rolling
- Longitudinal leg braces on infeed and discharge ends add impact resistance in truck loading environments
- Welded double horizontal leg braces for long-term structural durability
- 3-inch axle centers for the first 10 feet (small package zone at trailer nose) with 5-1/4-inch centers on remaining footage
- Heavy-duty 6×2-inch casters standard, with 8×2-inch upgrade available
- Four total-lock brake casters on the discharge end hold the conveyor stable during loading
- Heavy-duty roller package stop at discharge prevents cartons from falling off and doubles as an ergonomic handle for pushing/pulling the conveyor in and out of trailers
- Zinc-plated skatewheels with steel ball bearings standard; black polymer wheels also available
- Self-tracking design keeps cartons on path through curves without engineered sections
- Ergonomic side handles for safe conveyor expansion and contraction
Truck Loader System Integration
The 376PL is designed to work as part of a complete truck loading system. The guide track assists operators in extending and retracting the conveyor out from underneath a fixed feed conveyor, keeping the flexible section aligned and centered as it moves in and out. The herringbone transition provides a smooth handoff of packages from the fixed conveyor down to the 376PL, centering cartons as they transfer between the two surfaces. Together, these components create a seamless connection between your fixed sortation or feed line and the expandable loader in the trailer.
Applications
The 376PL is the standard choice for outbound loading operations in distribution centers, third-party logistics facilities, and high-volume retail shipping departments. It excels in environments where trailers are loaded continuously throughout the shift and the conveyor must extend, retract, and reposition quickly between loads. The optional rigid discharge cart keeps the trailer end of the conveyor in a fixed position to handle slug releases from feeder conveyors without buckling under line pressure. The optional power assist helps operators safely maneuver heavy, fully extended conveyors into and out of trailer noses with minimal physical effort.
Sizing and Configuration
The 376PL is available in 18, 24, and 30-inch widths with extended lengths from 26 to 68 feet — the longest reach in the NestaFlex flexible gravity lineup. Conveyor heights are preset based on the specific loading application. Standard axle centers are 3 inches for the first 10 feet and 5-1/4 inches for the remaining length. All conveyor products can be modified to suit specific design requirements — contact Barron Equipment for custom lengths and configurations.
