TADANO Automatic Moment Limiter
(Model:AML-L)
Main unit in crane cab gives audible and visual warning of
approach to overload. Automatically cuts out crane motions
before overload. With working range (load radius and/or
boom angle and/or tip height) limit function.
Eight functions are constantly displayed.
Digital liquid crystal display:
Either Either Boom angle or moment %
Either boom length or potential hook height
Either actual load radius or swing angle
Actual hook load
Permissible load
Either jib offset angle or number of parts of line of rope
Boom position indicator
Either outrigger position or on-tire indicator
Bar graphical display:
Either moment as percentage or main hydraulic pressure and torque converter oil pressure (Display
changes by alternation key )
OUTRIGGERS
4 hydraulically operated outriggers. Each outrigger
controlled simultaneously or independently from the
cab. Equipped with sight level gauge. Floats mounted integrally with the jacks retract to within vehicle
width. All jack cylinders fitted with pilot check
valves.
