GENERAL INFORMATION

The PAT Rated Capacity Limiter (RCL) DS 350 has been designed to provide the crane operator with the
essential information required to operate the machine within its design parameters.

Using different 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 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 350 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.

WARNINGS

The RCL is an operational aid that warns a crane operator of approaching overload conditions and of over
hoist conditions that could cause damage to equipment and 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 crane operation shall remain with the crane operator who shall ensure that
all warnings and 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 indicator and crane.

Proper functioning depends upon proper daily inspection and observance of the operating instructions set
forth in this manual. Refer to Section 6.

Pre-Operation Inspection and Calibration Verification

of this

handbook.

The RCL can only work correctly, if all adjustments have been properly set. For correct adjustment, the
operator has to answer thoroughly and correctly all questions asked during the setup procedure in
accordance with the real rigging state of the crane. To prevent material damage and serious or even
fatal accidents, the correct adjustment of the RCL has to be ensured before starting the crane
operation.
