Also Known As:
BS 4878:1973 is a standard that outlines the specifications for Large (Vee-Throated) Haulage Rope Pulleys used in mines and quarries. The standard focuses on pulleys with diameters ranging from 600 mm to 2100 mm. These pulleys are designed to incorporate rolling bearings in the boss, although there are provisions for pulleys with bearing bushes in associated pedestals as well, with diameters of 600 mm and 1350 mm.
The standard provides detailed guidelines for the classification of pulleys based on their various design criteria. It covers aspects such as the construction of shafts, pedestals, and bearings, as well as specifying the required levels of workmanship, inspection, and marking. The standard also includes an appendix that offers further explanatory information, along with graphs and illustrations to aid in understanding the requirements.
