The Upright -55 Series may be mounted upright on one or two structural I-beams. These head blocks have fully enclosed sheaves and the base angles are turned in and notched to allow easy passage of lift lines.

Additional Information

  • ASTM Class 30 grey iron or nylon sheave.

  • 10-gauge side plates fully enclose sheave; 16″ blocks have 7-gauge side plates.

  • Side plates are bolted and welded to the base angles for extra strength.

  • Six spacers between the side plates, four prevent cables from escaping the sheave grooves.
