It is suitable for cargo hoisting, protecting the lives of ground operators and preventing damage to the hoisted workpiece. The fall arrester uses the speed difference of the falling object for self-control, and is hung high and used low. When using the TXS2 series, you only need to cross the nylon rope over the solid and blunt-edged structure above, hang the iron hook on the nylon rope on the "n" shaped ring, and hang the iron hook on the wire rope into the semicircular ring on the safety belt.
