1. Structure and function

– Double hook design: The left and right T-shaped threaded screw and sleeve are combined. The sleeve is rotated by the ratchet to realize the screw-in or screw-out, so as to adjust the tension or loosening. The hook head is equipped with a safety pin and a lock plate to prevent the wire rope or stranded wire from being unhooked.

– Ratchet mechanism: The built-in reversible pawl controls the forward and reverse rotation of the sleeve through the handle. It is easy to operate and has an anti-reversal function to ensure the safety and stability of the tensioning process.

– G80 chain: Some models are equipped with G80 grade high-strength chain

2. Application scenarios

– Power construction: used for tightening overhead line conductors, adjusting insulator strings and installing wires,

– Logistics and transportation: suitable for bundling and fixing goods such as trucks and vans

– Railway anti-slip: A new anti-slip device designed specifically for railway vehicles uses a tension spring structure to disperse stress, prevent wire rope breakage, and is easy to maintain.

3. Advantages and Features

– Safety: Anti-unhooking design (safety pin, lock plate), non-slip handle, detachable structure (easy to store), etc. improve operational safety.

– Convenience: 360° rotating handle, reversible pawl, quick tensioning mechanism, reducing manpower consumption.

– Durability: Use high-strength materials (such as G80 chain) and rust-proof technology to extend service life.
