Product overview
Two construction forms
Square-base body
A round body on a square mounting foot, with a small rounded central boss and a short side cable exit.
Drawing capacity group: 100 kg–30 t.
Round body
A larger circular body with a flat-topped central boss, perimeter mounting openings and a side connection.
Drawing capacity group: 40–200 t.
The low-profile spoke structure uses the shear-stress principle for load measurement.
Square-base dimensions · 100 kg–30 t
L is the square base width; K is the corner-hole spacing. H1 marks the base thickness and H2 the cylindrical-body height in this drawing. Dimensional units require confirmation. Request a mounting drawing for the selected capacity and body shape before machining the fixture.

Circular-body dimensions · 40–200 t
The top reference depicts eight holes; the 40–50 t row specifies four. ØB is the mounting circle, ØD the smaller hole diameter and ØD1 the counterbore diameter. H1 and H2 follow this circular-body drawing. Dimensional units require confirmation. Request a mounting drawing for the selected capacity and body shape before machining the fixture.
