Hoisting Point Block for Transmission Line Construction | 50–80KN Heavy Duty Lifting Pulley
Product Introduction
The Hoisting Point Block is a lifting and guiding pulley block designed for transmission line construction, pole erection, and utility hoisting work. It is mainly used for fixing the hoisting point on an A-shape lattice structure holding pole, helping replace or support traditional hoisting tackle during field installation.
This product is available in 50KN and 80KN rated load models, with 160mm and 190mm sheave diameters. Its single-sheave structure is suitable for rope hoisting, lifting point positioning, and utility construction applications where a defined lifting direction is required.
The Hoisting Point Block is commonly used in power line construction projects, especially for pole installation, tower erection support, and lifting operations in overhead line work.
