Sollevatore a trazione manuale per funi metalliche
Tieshou wire rope pulling hoist (commonly designated as a mechanical wire rope puller or winching block) is an ultra-versatile, portable manual tool engineered for heavy-duty lifting, tensioning, and lowering across unlimited distances. Operating on a continuous walking-grip principle, internal dual-jaw mechanism alternate clamping forces onto the steel cable, delivering unlimited wire rope travel that bypasses the capacity limitations of conventional drum winches.
Encased within a high-strength, corrosion-resistant lightweight aluminum alloy housing, this manual puller is highly optimized for remote field operations including emergency vehicle recovery, forestry log skidding, electrical steel tower erection, and structural construction positioning. Equipped with built-in overload protection shear pins in the forward handle, the hoist ensures maximum operator safety by shearing under a 25% overload, while allowing immediate pin replacement under full load containment without dropped risks.
