OMAC F145.S Detachable 2/3 Conductor Pulley

The OMAC F145.S is a detachable three-sheave running-out block fit for stringing two- or three-bundled conductors. It shares its sheave sizes with the standard F145 but is built with detachable sheaves.

The aluminium sheaves are mounted on sealed ball bearings with nylon-lined grooves, and the central sheave, which carries the pulling rope and running board, runs on double bearings. The galvanised steel frame hangs from a demountable attachment that revolves by 90°.

Six sizes are listed: Ø500 mm (40 kN, 120 kg), Ø650 mm with 68 or 95 mm grooves (60 kN, 143–160 kg), Ø800 mm with 68 or 95 mm grooves (60 kN, 150–202 kg) and Ø1000 mm with a 95 mm groove (66 kN, 227 kg).

Options are aluminium-sector sheaves (opt. 314), a grounding device (opt. 326) and a 6 m copper earthing cable with tower clamp (opt. 329). For quad-bundle conductors, the matching detachable block is the F149.S.

Optional Devices

• Sheaves lined with aluminium sectors.
