Rated Capacity Limiter
General Information
The PAT Rated Capacity Limiter (RCL) DS 160 has been
designed to provide the crane operator with the essential
information required to enable the machine to be used within
its design parameters.
Using various sensing devices, the Rated Capacity
Limiter monitors various crane functions and provides the
operator with a continuous reading of the crane's capacity.
The readings continuously change as the crane moves
through the motions needed to make the lift.
The RCL provides the operator with information
regarding the length and angle of the boom, working radius,
rated load and the total calculated weight being lifted by the
crane.
If non permitted conditions are approached, the DS 160
Rated Capacity Limiter will warn the operator by sounding an
audible alarm, lighting a warning light and locking out those
functions that may aggravate the crane's condition.
*Load Moment: Generally the product of a force and its
moment arm; specifically, the product of the load and the
load-radius. Used in the determination of the lifting capacity
of a crane.
Warnings
The RCL is an operational aid which alerts a crane
operator of approaching overload conditions and also warns
of two block conditions which could cause damage to
equipment and harm personnel.
The device is not, and shall not, be a substitute for
good operator judgment, experience and use of
accepted safe crane operating procedures.
The responsibility for the safe operation of the crane
shall remain with the crane operator who shall ensure
that all instructions supplied are fully understood and
observed.
Prior to operating the crane, the operator must carefully
and thoroughly read and understand the information in this
manual to ensure that he knows the operation and limitations
of the indicator and crane.
Proper functioning is dependent upon proper daily
inspection and observations of the operating instructions set
forth in this manual.
The displays will only aid the operator when the RCL
is properly programmed and the proper load capacity
chart is selected for the crane configuration being
utilized. To prevent property damage or serious bodily
injury or death to personnel, ensure the RCL is properly
programmed before operating the crane.
