Technical data available on Gemini-Google:
The Hiller & Lutz HP71 is a classic, robust hand 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 typical 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 frame size/frame width, and 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 fully raised)

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

Machine features
Design: Solid cast iron stand in a C-shape for high rigidity.

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

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

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