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.
A spring, torque reducer, and variable-radius pulley keep railway wire tension constant through thermal length changes without bulky counterweights.
An internal counterweight in a hollow pole stabilizes overhead cable tension, reducing wear and breakage while generating power from movement.
A wireless link lets the puller control tensioner settings in real time, cutting response delays, operator error, and conductor damage risk.
Automatic direction switching and ratchet locking let this live-wire tensioner extend rope distance freely while preventing reverse rotation and backlash.
Wireless puller-to-tensioner control enables one operator to adjust conductor stringing in real time, reducing delays, errors, and damage.
A pendulum-driven ratchet wire grip switches drum direction through the operating lever, enabling remote live-wire work while preventing backlash.
A ratcheted clamp and connecting line let robotic appendages create cable slack while maintaining line tension for safer live insulator work.
A robot-manipulated tensioner and clamps create slack in live electrical cables, enabling safer remote repair and replacement work.
Bimetallic strips automatically vary traction force with temperature to keep cable tension constant without bulky winding space or manual retensioning.
Helical legs with distinct surface roughness provide radial compression for wire tension while protecting the outer sheath from damage.
