Prorope Rope Test Database

Prorope Test Lab

Rope test database

Measured breaking strength of 104 ropes and rope constructions. No manufacturer figures — our own tensile tests, with the spread included.

104test series
520pulls
50 kNtensile bench
ISO 2307:2019basis of the protocol

Every test series consists of five pulls on the same rope. The table lists the average, lowest and highest breaking force per series. Filter by material, diameter, construction or knot, or search for a rope directly.

All tests were carried out by Otto Tromm
