TERM DEFINITION
Anchors Bolts used to fix masts to the floor
ATF Automatic transmission fluid
Autotrol A seven-function valve block that performs the hydraulic functions of Freightlifts.
Back frame The vertical portion of the carriage on the cantilever Freightlift
Cable Wire rope that is used in lifting the carriage
Cable
Reeving The path of the wire rope beginning at the connection to the carriage, over the sheaves,
and ends at the top of the masts.
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 A mechanical hydraulic means that transmits lifting force through the use of cables and
sheaves.
Cycle The lift is considered to have operated one cycle any time the motor starts.
Down
solenoid An electrical mechanical device that, when electrically energized, opens the down valve.
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.
Hydraulic Operation by movement and force of liquid
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.
Masts The vertical members between which the carriage is guided throughout its vertical travel.
Motor starter An electrical controller for accelerating a motor from rest to normal speed.
