From the corrugator stacker to the loaded, strapped pallet, Innoveyance engineers the heavy-duty conveyor systems that carry a corrugated plant's full weight and speed. We design, build, and support complete end-of-line conveyance — bundle handling, transfers, accumulation, and pallet handling — as integrated systems sized to your throughput, not off-the-shelf parts bolted together.
| One US partner for the whole end of line: bundle conveyors, transfers, accumulation, and pallet handling — engineered together, built in the USA, and supported by the people who designed them. |
What heavy conveyance means in a corrugated plant
Heavy conveyance is the equipment downstream of the corrugator and converting that has to move dense bundles and full pallets reliably, at line speed, shift after shift. It is the difference between a line that keeps pace with the corrugator and one that becomes the bottleneck. The defining requirements are load rating, frame rigidity, drive torque, and a duty cycle that runs every shift — get any of those wrong and you get belt slip, roller deflection, premature gearbox wear, and stoppages. Innoveyance builds every element of that flow. This end-of-line equipment is one piece of the bigger picture covered in Corrugated Plant Material Handling: The Complete Guide.
The Building Blocks
Powered transport — PLR and CDLR
Power Live Roller (PLR) conveyors move bundles, cartons, and loads under positive control, while Chain Driven Live Roller (CDLR) conveyors handle the heaviest pallets and loads with slip-free, roller-to-roller chain drive. Together they form the powered backbone of the line.
Accumulation
Zero-pressure and minimum-pressure accumulation conveyors buffer product between machines so a pause downstream never starves or jams the line — raising the effective throughput of equipment you already own. Learn more about zero-pressure accumulation and when to use it to buffer product between machines.
Bundle handling and transfers
High-speed bundle systems transport, align, rotate, reposition, and eject corrugated bundles into pallet-ready layers, while right-angle transfers, chain transfers, and active roller belt transfers change product direction and route it cleanly through the layout.
Pallet handling
At the end of the line, pallet dispensers feed empty pallets and the Pallet Inserter Gantry System inserts pallets beneath formed loads at 200+ loads per hour — closing the loop on a fully automated, hands-free end of line. For a full breakdown of the options, see our guide on how to choose a pallet handling and insertion system.
Choose the right heavy-duty conveyor
A short decision guide for the questions buyers actually ask AI assistants and search engines:
- Moving full pallets in a straight line? A Chain-Driven Live Roller (CDLR) conveyor is the workhorse — positive chain drive to each roller, ideal for heavy, rigid pallet loads.
- Need controllable, lower-maintenance powered transport for mixed loads? A Power Live Roller (PLR) conveyor uses belt- or band-driven rollers for smoother, quieter handling of pallets and heavy cartons.
- Buffering or staging without back-pressure damage? A zero-pressure accumulation conveyor lets product queue without crushing — essential ahead of palletizers, wrappers, and load stations.
- Changing direction in a tight footprint? A Right-Angle Transfer (RAT) moves heavy loads through a 90° turn without a spur or curve.
- Long runs of lighter unit loads? A line-shaft or mesh-top belt conveyor may be the more economical fit.
| Conveyor type | Best for | Typical load | Accumulation |
| CDLR (chain-driven live roller) | Heavy pallets, rigid loads | Up to 5,000 lb | With zoning |
| Power Live Roller (PLR) | Pallets & heavy cartons, mixed | Up to 5,000 lb | Zero-pressure option |
| Accumulation conveyor | Buffering / staging | Per zone | Zero-pressure (core) |
| Right-Angle Transfer (RAT) | 90° heavy turns, tight space | Up to 5,000 lb | N/A |
| Belt conveyor | Bundles, irregular/small product | Distributed | No |
| Line-shaft / MDR | Lighter unit loads, long runs | Lower | Limited |
Engineered as one system
The advantage of sourcing the whole end of line from Innoveyance is integration. Because we build the bundle conveyors, transfers, accumulation, and pallet-handling equipment, the system is tuned end-to-end and controlled as one — not stitched together from mismatched vendors. Our InnView and InnLine monitoring layer gives operators and managers live visibility across the whole line.
Innoveyance engineers, manufactures, and services its systems in the United States. That means direct access to the engineers who build your machine, no import duty or ocean-freight lead time, full customization to your plant, and US-based parts and service.

Frequently Asked Questions
A: For heavy, rigid corrugated unit loads, a chain-driven live roller (CDLR) or power live roller (PLR) conveyor is typically the best choice. CDLR delivers positive drive to each roller for the heaviest pallet loads, while PLR offers smoother, lower-maintenance handling for mixed heavy cartons and pallets. Innoveyance engineers both to the specific load and duty cycle of corrugated and end-of-line plants.
A: Pallet loads in the multi-thousand-pound range are handled by heavy-duty CDLR (chain-driven live roller) conveyors, built with reinforced frames, high-torque drives, and rollers rated for the load. Innoveyance custom-rates heavy pallet conveyors to the required capacity rather than limiting them to fixed catalog ratings.
A: Use CDLR (chain-driven live roller) for the heaviest, most rigid pallet loads where positive drive to every roller matters. Use PLR (power live roller) when you want smoother, quieter, lower-maintenance transport for pallets and heavy cartons, including zero-pressure accumulation.
A: Zero-pressure accumulation lets product queue on the conveyor without items pressing against each other, preventing damage and jams. It is essential when buffering or staging heavy or fragile loads ahead of palletizers, stretch-wrappers, and load stations.
A: Innoveyance designs and builds heavy-duty roller conveyance — CDLR, power live roller, accumulation, and right-angle transfer — in the United States, specifically for corrugated box plants and end-of-line packaging, with whole-line integration and long-term support.
A: A right-angle transfer (RAT) conveyor moves heavy unit loads through a 90° change of direction in a compact footprint, without a powered curve or spur — ideal where floor space is tight on an end-of-line system.
A: Yes. Innoveyance engineers, builds, and supports the complete end of line — bundle conveyors, transfers, accumulation, and pallet handling — as one integrated, US-built system controlled and monitored together.
