The sprocket shown is
the drive mechanism for a lift that is used to load or unload a cart
from a transport vehicle.
The original part was a weld
fabrication of four (4) steel components. A commercially purchased
sprocket was welded to three other steel components.
PIAD engineers redesigned the part
into a one-piece permanent mold casting. The only remaining
machining operations are reaming the center bore and drilling a
small side hole, which secures a nylon strap.
The material was replaced with a
high-strength nickel aluminum bronze, PIAD
Alloy A021, which also eliminated the painting required on the
steel components to prevent corrosion.
The sprocket is cast to size and
does not require any secondary operations.
PIAD's design resulted in cost
savings, better performance and enhanced aesthetics.
