TEST Information

Test for Breaking Strength

Test machine : 600T, 20T, 0.5T - Tensile test machine

These testing machines are to measure breaking strength of fiber yarns and ropes by putting a certain load on a specimen at a constant speed. During the process, Elongation at break can be also checked.

Test for fatigue life & durability

Test machine : 20T - Fatigue test machine

This test is to analyze deformation and damage that occur in repetitive use of fiber ropes after reenacting various environmental condition with cyclic loads. During the process, a broken mechanism is examined in several conditions such as repetitive bending, stretch and friction etc.. The test procedures for TCLL(Tension Cycle Load Limit) can also enable us to check maximum allowable load in each cycle and evaluate the stability of long-term use and performance for fiber ropes.

Test for abrasion resistance & frictional property

Test machine : Friction test machine by using sandpaper

Damage by abrasion and friction can be converted into quantitative assessment in this test. This helps us design each material and structure and optimize coating technology in order to secure safety and durability in actual use.

Test for bending load and dynamic performance

Test machine : Cyclic Bend Over Sheave (CBOS)

This procedure is to precisely reenact dynamic characteristic, fatigue and abrasion phenomenon of a fiber rope exposed to repetitive bending loads passing through a sheave. We can measure abrasion- & fatigue-damaged effect, durability of materials and dynamic performance by cyclically bending a rope in this test. The data resulting from this test contributes to develoment of a safe and highly reliable rope by optimally choosing a material, designing a structure and improving a manufacturing process.

Test for weatherization affected by environment

Test machine : Weatherization Chamber (Temperature: -50℃ ~ 200℃)

We analyze changes in a fiber rope exposed to weatherization in the long term by utilizing the chamber and adjusting various environmental factors such as heat, humidity, UV rays etc. This test helps us evaluate changes in physical & chemical properties of fiber ropes and predict a long-term durability and contribute to setting up a plan to improve quality and optimize manufacturing process.
