What 400 Ton Capacity Means in Practice
Small and medium forgings
The 400-ton class covers small and medium automotive and general engineering forgings: hand tools, brackets, small flanges and light structural components. Table sizes on machines in this class (around 500×500 mm to 560×800 mm) suit compact die sets and shorter production runs.
Coining, sizing and calibration
Knuckle joint presses in this class handle coining, sizing and calibration of small-to-medium steel parts rather than hot forging. The toggle mechanism delivers maximum force at bottom dead centre, giving dimensional accuracy a hot forging press cannot match on its own.
Workshop-scale production
At 400 tons, both press types fit shops with limited floor space and lower production volume than the 1000-ton class and above. Machine footprint and weight stay manageable for smaller forging operations entering or expanding production.
Hand tools and fasteners
Typical parts at this tonnage include hand tools, small automotive brackets, fasteners and light engineering components that need moderate force over a short stroke.
Hot Forging Press vs Knuckle Joint Press at 400 Ton
The two 400-ton machines TRIGA has offered show how different presses with the same nominal rating can be. The Farina GAS-400 hot forging press, built in Italy in 1981, has a 180 mm ram stroke and runs at 120 strokes per minute on a 40 HP motor, with a table of approximately 560×800 mm; it suits forging of automotive and machinery components and hand tools. The Barnaul KB8336 knuckle joint press has a 130 mm stroke and runs at 50 strokes per minute on a 12 kW motor, with a 500×500 mm table and 8,500 kg weight; it is built for coining, sizing and calibration where maximum force lands at the bottom of the stroke. Same nominal rating, different process in every other respect.
Transport and Installation
Machine weight
Both 400-ton machines in this class are compact. The Barnaul KB8336 weighs 8,500 kg and measures 1,940×1,240×2,800 mm; the Farina GAS-400 is a similar scale at approximately 2,200×1,800×4,000 mm. Either fits on a standard heavy flatbed without special lifting equipment.
Permits and routing
Machines at this tonnage need oversized transport permits only in exceptional cases. Standard EU road limits (2.55 m width, 4.0 m height) cover both presses assembled, which simplifies route planning compared to larger tonnage classes.
Foundation
Refer to the manufacturer's foundation drawing for anchor bolt layout and recommended concrete depth. A compact 400-ton press needs a lighter foundation than the 1000-ton class and above; TRIGA provides the original documentation for all machines we offer.
What to Check at Inspection
Frame and uprights
Check the upright-to-crown connection for cracks. On machines of this age and size, weld repairs in the frame structure warrant investigation before purchase.
Toggle pins and gibs (knuckle joint)
On the Barnaul KB8336 and similar knuckle joint presses, measure toggle pin and bushing clearance and check slide guide (gib) wear. Worn pins cause load eccentricity and die misalignment in coining and sizing work.
Clutch and brake (hot forging)
On the Farina GAS-400 and similar hot forging presses, verify clutch engagement and disengagement response, and inspect friction lining thickness. A worn brake increases the stopping angle and creates a safety certification problem.
Lubrication system
Check the automatic lubrication system where fitted (the Farina GAS-400 uses a DropsA system) for correct operation. A failed automatic lubrication system accelerates wear on running gear.
Electrical cabinet
Original cabinets on machines from this era may no longer meet local electrical safety standards. Assess cabinet condition during inspection and budget for renewal before putting the machine into production.
FAQ
Frequently Asked Questions
The 400-ton class handles small and medium parts: hand tools, automotive brackets, fasteners and light structural components. Knuckle joint presses in this class handle coining, sizing and calibration; hot forging presses handle series forging of smaller parts in heated dies.
The knuckle joint press, like the Barnaul KB8336, delivers maximum force at the bottom of the stroke: the right tool for coining, sizing and calibration. The hot forging press, like the Farina GAS-400, runs a longer stroke at higher strokes per minute for series production of hot-formed parts. Both carry the same nominal tonnage but serve different processes.
The Barnaul KB8336 knuckle joint press weighs 8,500 kg. The Farina GAS-400 hot forging press is a similar compact scale. Both fit on a standard heavy flatbed without special lifting equipment.
We arrange physical inspection at the storage location for every machine we offer. Running the press under power depends on the electrical connection at the site. Contact us to confirm the specific machine's status and arrange a visit.
TRIGA coordinates crane work, loading onto flatbed or low-loader, and export documents. At 400 tons, both machine types are compact enough that transport is straightforward compared to larger tonnage classes.
Yes. The Farina GAS-400 hot forging press and the Barnaul KB8336 knuckle joint press are both available now, located in Europe. Contact us with your tonnage, type and application requirements and we will advise on current availability.
