- Despite being compact and lightweight, this reel provides a long stroke of up to 4m (winding length).
- Due to the use of a cylindrical drum, the tension (winding force) increases gradually as the wire rope is pulled out.
- The cylindrical drum also prevents cable jamming even when you pull out the wire rope in an oblique direction.
- Balance is obtained at the preset height and the wire rope is wound up after being pulled out again.
- The models with the ratchet mechanism (ER-3A, 5A, 10A) can be stopped even during strokes.
