Here are the typical technical specifications for this model:

Technical Details (reference values)
As these machines have been produced over several decades, details may vary slightly depending on the year of manufacture:

Pressing force: approx. 20 to 25 tonnes (the "71" refers mainly to the frame size/clear opening, pressing force results from the spindle pitch and flywheel diameter).

Spindle diameter: approx. 70 – 80 mm

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

Throat depth: approx. 250 – 300 mm (distance from spindle center to frame)

Table size: approx. 500 x 400 mm

Clearance height: max. approx. 400 – 500 mm (with spindle fully raised)

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

Machine features:
Design: Heavy-duty cast iron C-frame for high rigidity.

Drive: Manual via large flywheel; energy is generated by the flywheel’s inertia during downward threading.

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

Weight: Net weight typically between 700 kg and 950 kg, ensuring stable positioning (usually requires bolting to the foundation).

Gemini says:
The dimensions of the Hiller & Lutz HP71 depend substantially on whether just the body or the total space requirement including the flywheel overhang is considered. Here are the specific dimensions for this model:

Basic machine dimensions (body only):
Height: approx. 1,800 mm to 2,100 mm (depending on spindle position).

Width (frame): approx. 500 – 600 mm.

Depth (base): approx. 800 – 1,000 mm.
