TERM DEFINITION
Anchors Bolts used to fix masts to the floor
ATF Automatic transmission fluid
Back frame The vertical portion of the carriage on the cantilever Freightlift
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
Chain
Controls Any electrical device used in the operation of a Freightlift, which normally includes push
button stations, control boxes, limit switches, interlocks, etc.
Cycle The lift is considered to have operated one cycle any time the motor starts.
Drive Gear motor drive located at top of lift mounted to the drive base tube
ECS Electrical Current Sensor – located in the motor control panel & designed to keep the
current overloads from kicking out as a result of high initial amp draw at motor start
Enclosure A structure surrounding the Freightlift to prevent anything from interfering with normal
operation of the lift, and to protect personnel. Typically eight-foot high panels made of
expanded metal that will prevent a two-inch diameter ball from passing through. This is a
requirement of the conveyor code (ANSI-B20.1)
Gate A device that opens and closes to allow access to the carriage for loading and unloading.
Normally a swing, sliding, or vertical acting device constructed of similar expanded metal
as the enclosure.
Interlock An electrical mechanical system for doors or gates to prevent operation of the lift if all the
gates are not closed or if the lift platform is not level.
Limit Switch An electrical device by which the movement of the Freightlift may be controlled within
predetermined limits.
Load height The maximum height of the material a carriage can accommodate.
Load pattern A method to describe how a Freightlift will be loaded at different levels.
Locking Cam Free-fall arrest safety device attached to the lifting chain to sense slack chain conditions
and automatically & mechanically lock / jam carriage into the guide beams
Masts The vertical members between which the carriage is guided throughout its vertical travel.
Mechanical Actuated by mechanical means – i.e. through gear motor drive to chain & sprockets
