Product description
The new design offers the reliability of standard McKissick® folding blocks, making this series the ideal choice for heavy-duty applications, such as use on tugger winches or rigging.
- Galvanized surface.
- Blocks of 203 mm and 254 mm are suitable for two rope gauges.
- Swivels, connectors, hook bearings and shackles made of hardened and tempered forged steel.
- Easy maintenance thanks to rope sheave lubrication via centrally mounted nipple.
- Safety factor of 4:1.
- All blocks 356 mm and larger feature McKissick® Roll Forged™ sheaves with flame-hardened groove.
- Recessed side sections reduce the gap between the sheave rim and side section, so the sheave will not fall out of the block even if the center pin is lost.
- Encapsulated tapered sheave bearings increase pin and bearing life. At the same time, this allows higher rope speeds than with conventional folding blocks.
- Easy positioning due to swivel shackles.
- Suitable for passenger transport provided all personnel, including the winch operator, have been trained to follow all applicable national, local and industry guidelines.
