TRANSPORTING
 B66
HOISTING; LIFTING; HAULING
 B66D
CAPSTANS; WINCHES; TACKLES, e.g. PULLEY BLOCKS; HOISTS (winding or unwinding ropes or cables for feeding or storage purposes B65H; rope or cable-winding or unwinding mechanisms for lifts B66B; hoisting devices specially adapted for suspended scaffolds E04G 3/28)
 B66D

Note(s)

This subclass covers:

  • rope, cable, or chain winding or unwinding mechanisms for moving all loads except lift cages, e.g. winches for dredges;
  • braking or detent devices characterised by their application for retarding, or preventing, rotary movement of a winding drum or barrel.
