The Mereen-Johnson Scout Loader is an automated lumber loader that feeds deadpacked lumber straight into the Rip Navigator Scout — with no manual handling. As a vacuum lumber loader, it lifts each layer of boards off the bunk with vacuum assist and transfers it into the line, working as a hands-free lumber infeed system and automatic board feeder. In a compact footprint — smaller than an unscrambler or tilt hoist — it saves labor, reduces material-handling damage, and keeps the optimizing rip line fed.
| Capacity | 4′ wide × 4′ tall × 17′-6″ maximum bunk capacity. |
| Transfer Carriage | Four vacuum boxes mounted from a heavy steel-frame carriage riding on V-castors and rails. |
| Even End Roll Case | Combination of 3-1/2″ driven and idle jump rolls arranged to receive each layer of boards and transfer to an end stop. |
| Lateral Chain Deck | Seven strands of chains integrated with the Rip Navigator Scout drive. |
| Electrical | Arranged for 3/60/230 or 460 volt power supply (other electrics available). |
| Shipping | Two skids: nominal 20′ × 7′ × 4′, 8,400 lbs; nominal 10′ × 8′ × 3′, 4,700 lbs. |
Specifications
Scout Loader will save labor, streamline production, reduce material handling damage, and will precisely transfer each layer of boards through vacuum lift assist without destabilizing the bunk. Partially used bunks can be returned to stock once production needs have been met.

The Scout Loader destacks a deadpacked bunk one layer at a time and feeds the boards into the Rip Navigator Scout — automatically:
The result is an automatic board feeder that turns a deadpacked bunk into a steady, hands-free supply of boards for the Scout — replacing manual loading in a compact footprint.
The Scout Loader automates the lumber-loading step ahead of a Rip Navigator Scout optimizing line:
As a vacuum lumber loader and automatic board feeder, it keeps the optimizing line supplied without manual handling.
The Scout Loader supports high-production operations running a Rip Navigator Scout line:
Emerging applications: any operation scaling up rip-line throughput and looking to cut lumber-handling labor and material damage.

What is the Scout Loader?
The Scout Loader is Mereen-Johnson’s fully automated lumber loader — a vacuum-assisted feeder that offloads deadpacked lumber bunks layer by layer and feeds the boards into the Rip Navigator Scout optimizing system.
How does it load lumber?
A transfer carriage with four vacuum boxes lifts each layer of boards off the bunk with vacuum assist (without destabilizing the stack), an even-end roll case squares the layer to an end stop, and a lateral chain deck feeds the boards into the Scout.
What is a “deadpacked” bunk?
A deadpacked bunk is lumber solid-packed without stickers between the layers. The Scout Loader is designed to offload these directly — no separate unscrambler needed.
How is it different from an unscrambler or tilt hoist?
It does the same job — feeding a rip line — in a much more compact footprint, using vacuum lift instead of tumbling or tilting the lumber, which also reduces handling damage.
What bunk size does it handle?
Up to 4′ wide × 4′ tall × 17′-6″ maximum bunk capacity.
Does it integrate with the Rip Navigator Scout?
Yes. Its lateral chain deck is integrated with the Rip Navigator Scout drive, so loading is paced to the optimizing line.
Can I return a partially used bunk?
Yes. Once production needs are met, a partially used bunk can be returned to stock.
Is it made in the USA?
Yes. The Scout Loader is designed and built by Mereen-Johnson in the USA.

Vertically integrated manufacturing in the USA means we control every step of the process to deliver the performance and longevity that the industry has grown to expect from us.
Listening to your specific needs, we will adapt a standard machine or develop a fully custom solution, including automation and robotics, and manufacture it in-house.
Our state-of-the-art production space has room to build, test and prove large-scale design solutions. Design-build teams work together to make your custom concept a reality.
We will always support your machine. From training programs to replacement parts, schematics to software support, we’ve got you covered, remotely or onsite.
