Bend test

Single bending Load range 100 kN
Tester	WBM 180, in-house development
Application	Testing of fibre ropes up to 16 mm diameter with rope tensile forces up to 100 kN
Parameter	Test sheaves for 12, 25 and 50 x d-rope, easily exchangeable due to hub system Spindle axis with servo motor and force control for generating the preload Lifting height up to 0.5 m and bending frequency up to 0.3 Hz freely selectable Non-contact monitoring of the rope temperature in the bending zone

Single bending Load range 12 kN
Tester	WBM 25, in-house development
Application	Testing of fibre ropes of 3 and 6 mm diameter with rope tensile forces up to 12 kN
Parameter	Test sheaves for 10, 12, 25 and 50 x d-rope, easily exchangeable due to flying bearing Spindle axis with servo motor and force control for generating the preload Lifting height up to 0.5 m and bending frequency up to 0.3 Hz freely selectable Non-contact monitoring of the rope temperature in the bending zone

Counterbending
Tester	In-house development
Application	Testing of fibre ropes from 4 to 6 mm diameter with test loads up to 30 kN
Principle	Passive rope and active sheave (the test sheave arrangement is moved over the standing rope)
Parameter	Test sheaves for 10, 12, 25 and 50 x dcable Lifting height up to 1.2 m and bending frequency up to 0.3 Hz freely selectable Recording of rope damage, visual determination of diameter possible during inspection Direct measurement of rope elongation in the damage zone Possibility of introducing a forced twist Increased bending cycles per clearance possible (meandering disc arrangement)

Multi-zone bending
Tester	Tester DEP Engineering, in-house further development
Application	Testing of fibre ropes preferably with 6 mm diameter
Parameter	Cable tensile forces up to 50 kN Test discs 5 x 150 mm Lifting height adjustable between 5.2 m and 16.3 m Setting of two different load zones (main load zone, secondary load zone) Generation of differently stressed bending zones (20 %, 40 %, 60 %, 80 % and 100 % of bearable bending cycles)
