Universal Loft Block 55 / 56 / 59 Series
Universal Loft Block
2NC-10855R
2NC-10855R
- May be mounted upright or underhung.
- May be supported by I-beams, grid wells, or Unistrut™.
- Nylon or ASTM Class 30 grey iron sheaves are available. Nylon sheaves are quieter, have a higher capacity, lower weight, and lower cost than blocks with cast iron sheaves.
- 8" blocks have a 24" base angle with a continuous pattern of holes and slots for universal mounting for a grip range up to 20". Multi-line block base angles have a series of mounting holes.
- 8-Line blocks have the base angles turned in, requiring different upright and underhung models.
- A clip package is available for single line blocks with a combination of J-bolts and clips for both underhung, and upright mounting options.
- Sealed precision ball bearings (Single line, 8" nominal sheave only) or tapered roller bearings
- Side plates fully enclose sheave.
- Five spacer between the side plates, three of which prevent cables from escaping the sheave grooves
- Pivot adapters (070-PIVOT) are available for single line 8" blocks used in applications where the mounting surface is sloped.
- Underhung loft blocks may need to be welded to loft beams after final alignment - consult the factory for specific information.
