Cam
Followers

Replaceable, high capacity, low impact rated, needle bearing rollers which run on the
mast beam flanges and support the full weight of the loaded cantilever carriage.

Cantilever

A style of Freightlift where the carriage rides along two masts that are mounted on the
same side of the carriage. This style of lift will accommodate all three loading patterns.

Capacity

The maximum load the Freightlift will lift

Carriage

The entire assembly that travels on the mast and carries the load

Controls

Any electrical device used in the operation of a Freightlift, which normally includes push
button stations, control boxes, limit switches, interlocks, etc.

Cylinder/Ram
