A detachable motorized power unit rotates the screw shaft to tension wire faster, with less manual force and safer one-person operation.
Sensors, motor control, and a counterweight keep cable tension within range during servicing, reducing tangling and manual adjustment.
A motor-actuated gripping mechanism speeds wire tensioning and release at height, improving safety and enabling single-person operation.
A cam-triggered clamp grips the cable when reverse motion signals breakage, preventing drop and keeping the line anchored during stringing.
