- Built for operations where the stacker has to hold pace with everything upstream. Pit unscrambler infeed, programmable stick placement, automatic stack lowering, and powered takeaway, running without anyone tending it.
Board Stackers
The right board stacker is determined by what's in front of it. A stacker running behind a gang saw, a notcher, or a band resaw is handling different material at a different rate, and that upstream machine sets the pace for the stacker.
From there it comes down to speed, floor space, and how much labor you want tied to the station. Some configurations run unattended. Others need an operator, cost considerably less, and take up less room. Whether you're stacking notched stringers, straight deck boards, or cants also changes the answer.
Pendu builds stackers across that full range, from units feeding a modest cut-up line to high-speed systems running 25 layers per minute. Tell us what's feeding the stacker and how fast it's running, and we'll design a configuration that fits.
Available across configurations, specified to your operation:
Programmable stick placement with adjustable magazines, so a change in board dimension is a setup change rather than a service call
Adjustable stack width with air cylinder escapement
Automatic stack lowering with hydraulic scissors lift
Powered takeaway with live roller outfeed and gravity rolls
Pac tamper for keeping light pine compacted through the stack
PLC controls with touchscreen and remote access
Board bypass on combined notcher-stacker systems, routing un-notched deck boards to the same stacker
Three things determine which configuration fits: what's feeding it, how fast, and how much floor you have.
Throughput: from 4,000 boards per hour on inline configurations up to 9,300 boards per hour, or 25 layers per minute on high-speed systems.
Material: boards from 3/8″ to 2 1/2″ thick, 1 1/2″ to 6″ wide, and 28″ to 72″ long, with cant handling up to 6″ x 8″ on configurations built for it.
Stack size: up to 48″ wide by 50″ high by 72″ long, with lowering tables rated to 6,000 lbs.
Comparison Guide

Filter by what's feeding the stacker and what's constraining you. If nothing fits quite right, Pendu builds custom systems to spec.
Filter by type:
- A smaller-footprint configuration for operations that need stacking capacity without the room a high-speed system requires.
- Notched stringers move from the notcher to the stacker with no crew stacking by hand. Handles the narrower profile and heavier per-piece weight stringers carry.
- Pieces lay out flat as they come off, where an operator can see and grade them before they're stacked.
- Sits lower to the ground than an over-the-top design, putting the stick placer and infeed within easy reach. Runs with or without a pit.
- Built to run inline behind a cut-up line, handling boards and cants as they come off the saw. Sized to the output of the machine feeding it rather than to a general throughput number.
FAQs
Frequently Asked Questions
How do I know which stacker I need?
Start with the machine feeding it. A gang saw, a notcher, and a band resaw each hand off material differently and at different rates, and that narrows the field before anything else does. Then it's speed, floor space, and labor. Tell us what's upstream, and we'll work through it with you.
How fast can a Pendu stacker run?
Up to 25 layers per minute on high-speed configurations, or 9,300 boards per hour depending on how you measure. Inline configurations behind a cut-up line typically run 4,000 to 6,000 boards per hour.
Does someone have to run the stacker?
It depends on the configuration. High-speed systems run unattended. Lower-cost configurations need an operator at the station, which is a real tradeoff worth weighing against price and footprint. A slower stacker that costs less and fits a tight floor is the right answer for plenty of operations, and we'll tell you when that's the case.
Can it stack notched stringers and deck boards?
Yes. Configurations exist for both, and on a combined notcher-stacker system a board bypass routes un-notched deck boards to the same stacker as finished stringers.
What if I need to grade material as it comes off?
Some configurations lay pieces out flat where an operator can see them, and others don't. If grading matters in your operation, mention it early because it points toward specific configurations.
How much floor space does a stacker need?
Footprints vary considerably across the line. Bottom-up designs sit lower and can work without a pit. If floor space is your constraint, say so up front, and we'll work within it.
If You Can Describe It, We Can Build It.
Tell us what's feeding the stacker, how fast it's running, and how much floor you have to work with. Pendu builds board stackers around the production you're actually running, from inline units behind a cut-up line to high-speed systems that run unattended.
