Abstract

967,691. Pulley hoists. HEINRICH DE FRIES G.m.b.H. June 8, 1962, No. 22274/62. Heading B8B. In a power-operated pulley hoist the housing comprises two parts 1, 5, Fig. 3, bolted together by bolts 6 (not shown) and each containing a pair of bearings 8, 15 and 17, 18 for the ends of the driving shaft 10 and chain wheel shaft 14 so that the shafts are readily removable on dismantling. In one example in which the hoist is driven by an electric motor, the drive shaft 10 has a pinion 9 of small diameter for withdrawal through the bearing 8 and engaging a large pinion wheel 13 on the chain wheel shaft 14. The motor is mounted in the casing part 5 and has a brake 31 operated through a slidable armature 28, the drive to the shaft 10 being through a coupling disc 29 and pins 30. The motor assembly with electrical connections is enclosed by cover-plates 7, 24 secured by screws 25. In a modification the hoist may be interchangeably fitted with a compressed air motor mounted within a casing 5a, Fig. 4, interchangeable with the casing 5. In this example the drive shaft 33 is driven through reduction gears 34, 12 from a pinion 34 on the motor shaft 11 and the shaft 33 is mounted at the driven end on a bearing 21 in the motor casing. The compressed air motor has a pneumatically operated multiple plate brake 32.
