The increased capacity of these two trolleys is due to the use of No. A-164 trolley wheel. This is a sturdy, heavy-duty drop forging with precision ball bearings and pressure lubrication. It assures smooth travel and trouble-free service. Four wheel trolley No- A-162 consists of two No. A-179 two wheel trolleys with No. A-167 load bar mounted in the saddle of the No. A-145 yokes. This load bar is regularly furnished with No. A-118 hoist hook bearing but any of the other fittings can be appliedmore at no additional cost.

The application of drop forgings at all load bearing points provide a greater margin of safety, extra long wear and lighter dead weight of the trolley itself. less
