How Digital Readouts Simplify Field Work for Power Transmission Pulling System

2026 06/05

Tension management is an obstacle that industry rod-pulling teams consistently in the global power transmission projects face, which is due to outdated analog-based pulling machines. This MARSHINE Power Transmission Pulling System generates a maximum pulling force of 80 kN and a constant output of 60 kN, so that he overhead cable laying work can be performed day and night. The operators also like to tailor the pulling speed, with a max rate of 95 m/min, so they can slow down when pulling more sensitive bundled conductors, and speed up when pulling common ground wires. This line stringing machinery has a groove-bottom diameter of 540 mm, 8 independent grooves, which is designed to precisely wrap up 21 mm steel wire ropes, precisely wraps up 65 mm cable accessories without any tangling or jamming of the wire rope.

This utility stringing equipment is driven by a water cooled diesel engine, and the pulling machine adopts the design of fully enclosed closed loop hydraulic circuit. When the hydraulic pressure suddenly falls down, the MARSHINE Transmission Stringing Equipment activates automatic brake locking right away, which can avoid huge wire rope damage and accident, even danger that could be faced if working environment embraced complex situation such as rough mountain terrain or riverbank environment. Building contractors will often opt for this machinery when taking on work in areas like stringing OPGW fiber-optic ground wires over valleys, swapping out deteriorated conductors as part of rural power grid modernization initiatives, and even stringing within confined spans when working on 220kV substation expansions.
