UnitedTest plastic tube, wire bollard tensile test grips bollard Grips are used on a Universal Testing Machine to perform tensile tests on filament material such as string, thread, wire and yarn.  The specimen is wrapped around a bollard or post and then secured with a vise grip mechanism.  The term bollard comes from the maritime industry and is used to describe a thick, short post on a ship deck or dock which is used to wrap a rope around to anchor the vessel.

Product use: The wire winding tensile fixture is the most commonly used accessory for tensile testing, which can test the elongation and tensile strength of linear materials (such as metal wire, fiber rope, etc.). It consists of two grips, the upper and lower, and the two ends of the specimen can be wound in the middle of the upper and lower grips. Before the tensile test, we need to mount the wire winding fixture on the tensile testing rig and apply force in different directions to the upper and lower grips to stretch the linear material until it breaks.

This fixture is suitable for tensile test of rope, and it is necessary to ensure that the wire rope can be wound when doing wire rope test. This fixture adopts a winding structure, which is locked and fixed after winding 3-5 times on the winding wheel, which can effectively prevent the rope from slipping or damaging the specimen after blessing and causing fracture in the jaw. For thicker ropes, this is also the case, but a larger scale clamp is required.
