Technical data on Gemini-Google:
The Hiller & Lutz HP71 is a classic, robust manual spindle press (often also referred to as a piercing press), which is primarily used in locksmith shops, workshops, and the metalworking industry for tasks such as straightening, bending, pressing, or punching.

Here are the common technical specifications for this model:

Technical details (approximate values)
Since these machines were manufactured over decades, details may vary slightly depending on the year of manufacture:

Pressing force: approx. 20 to 25 tons (The designation "71" often refers to the size/frame width; the force results from the spindle pitch and the flywheel diameter).

Spindle diameter: approx. 70 – 80 mm

Stroke: approx. 200 – 300 mm (depending on the spindle length)

Overhang: approx. 250 – 300 mm (distance from the center of the spindle to the stand)

Table area: approx. 500 x 400 mm

Through-height: max. approx. 400 – 500 mm (with the spindle rotated upwards)

Flywheel diameter: approx. 1,000 – 1,200 mm

Machine features
Construction: Solid cast iron frame in C-shape for high rigidity.

Drive: Manual, via the large flywheel; the energy is generated by the inertia of the wheel when the spindle is screwed down.

Table: Usually equipped with a central through-hole and T-slots for tool attachment.

Weight: The weight typically ranges between 700 kg and 950 kg, which guarantees a stable position (usually requiring bolted mounting to the foundation).

Width (stand): approx. 500 – 600 mm.
