Application
Machinery packing crate for heavy equipment and industrial assemblies
Machine tools, compressors, pumps, generators and production equipment are heavy, top-heavy and often loaded or unloaded at a single lifting point. That combination is what breaks a nailed timber crate: the panel splits, the corner opens, and the load shifts in transit.

What fails first on a machine crate
On machinery the base panel fails before the sides do. A machine stands on a small footprint relative to the size of the box, so the whole mass arrives as a point load on one or two areas of the floor panel. A nailed crate spreads that load through the nails, and the nails work loose in a way that is invisible until the box is opened.
The second failure is the corner. Machinery is lifted by sling, by forklift tine and by crane, and each method loads the corner differently. A timber corner block that has been nailed on takes the load once; after a handling cycle or two the fixing has enlarged its own hole.
The third is access. If the equipment has to be inspected at the destination port, a crate that was closed with a nail line is opened destructively and cannot be re-closed properly. Heavy duty shipping crates avoid that by using a joint that can be opened and closed again with the same method.
How heavy duty shipping crates are specified
Specification starts from the machine, not from the box. Three numbers decide the construction: the mass of the machine, the footprint through which that mass reaches the floor, and the lifting points. Everything else — panel thickness, base construction, internal bracing — follows from those three.
The second decision is which part of the box takes the handling load. In a steel-edged construction the formed steel edge carries it at the rim, which is why the edge is cold-rolled and pressed rather than stapled on. The panel carries the goods; the steel carries the lift.
Heavy duty shipping crates built this way can run panels from 5 mm to 12 mm on the DA-8000, with assembly length up to 9,000 mm. Above that length, or where the machine footprint is wider than the press working width of 2.5 m, the box has to be split or the process changed — those are drawings to look at together rather than assumptions to make.
Where a heavy duty crate stops being the answer
A rigid box is not always the right enclosure. If the equipment has to be assembled on site, or if the destination has no crane to lift a closed box off the truck, a knock-down construction that travels flat and is built around the machine is usually the better choice.
The same applies where the return leg matters. A closed rigid box that comes back empty pays for its own volume twice. On a closed loop, a foldable construction that returns flat changes the freight calculation more than any saving on the panel.
Packaging requirements
- Panels thick enough to hold the equipment weight without deflecting at the base
- Corners that survive slings, forklift tines and repeated handling
- A box that can be opened on site without destroying the panels, so equipment can be inspected
- Base construction matched to the machine footprint rather than a nominal box size
- Internal blocking that restrains the machine at its own hard points, not against a panel face
How our machines cover the steps
- The DA-8000 drives steel buckles through 5–12 mm plywood to lock the panel joints, so the box is fastened without nails splitting the panel edge.
- The GA-8000 forms galvanised steel strip around the box edges and corners — the part of the box that takes the lifting and handling load.
- The GA 2.5 m press closes and sets the formed steel edge with a 30 t nominal press force across a 2.5 m working width.
- The three stages are one sequence: fasten, form, press. A panel that leaves the press has its edge closed on both sides of the joint.

Machinery & Heavy Equipment Packaging — questions
The GA 2.5 m press is specified with a 2.5 m working width, and the press series is built with custom platen sizes to 1,300 × 8,500 mm. Send us the box sizes and panel thicknesses you build and we will tell you which stages of your box need a different process.
Not necessarily. If you already form steel edges, the DA-8000 fastening stage can be added on its own. Each machine is quoted with its own specification sheet so you can buy a single stage.
Blocking and bracing belong to the box design rather than to the machines we supply. The fastening stage affects it in one way: buckle joints let a brace land on a structural position and be removed again without leaving a nail line in the panel.
That depends on how the box is built and how it is handled, not on the fastening method alone. A steel-edged construction with replaceable panels is designed to be repaired rather than scrapped, which is what makes a second trip realistic.
