ELASTIC
Capable of recovering size or shape after deformation.
ERECTED
ATTACHMENT
An attachment on the main boom fitted in its working position.
EXTENSION SENSOR
A device which measures the extension of the telescoping sections of a boom.
FLY/JIB
Something attached by one edge such as a lattice fly or jib on a crane boom.
FORCE
Energy exerted, in this case by the suspended weight of an object.
GEOMETRY
A branch of mathematics that deals with the measurement and relationships of points, lines, angles,
surfaces and solids.
GRADUATED
Marked with degrees of measurement.
HEIGHT
The vertical distance from the ground to the tip of the boom or attachment.
HITE
An abbreviation of the word height. The height of the boom pivot above ground level.
HORIZONTAL
Parallel to the horizon.
HYDRAULIC
CRANES
Operated using the pressure of oil.
INCREMENT
The action of increasing a number or value.
INITIALIZE
Erase all data from a memory prior to a new calibration.
INTEGRATED
CIRCUITS
A tiny complex of electronic components and connections on a small slice of material (such as
silicon).
MEASURE HEIGHT
The vertical distance below the boom pivot at which radius measurements are to be made
when calibrating.
MICROPROCESSOR A computer processor contained on an integrated chip.
MILLIVOLT
One thousandth of a volt.
MOMENT
The product of force and distance to a particular axis or point.
OUT OF DUTY
A point which is either longer than the longest permitted radius or lower than the lowest
permitted angle on a capacity chart
OUTRIGGER
A projecting support run out from a main structure to provide additional stability or support.
PERSONALITY
Data stored in the calibration EEPROM.
PRESSURE
Hydraulic pressure in the boom hoist cylinder
RADIUS
The horizontal distance from the center line of rotation to the center of the hook.
RATED CAPACITY
The lifting capacity of a crane as determined by the published capacity chart.
RATED CAPACITY
The load that a crane can safely handle based on factors such as strength, stability and rating.
RATING
A factor determined by legislation that limits the proportion of a cranes capabilities which may
be utilized in a lifting operation. Usually expressed as a percentage of strength or stability.
RESTORE
Move data from a back-up chip into the working personality.
