1. GENERAL INFORMATION

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

The PAT DS 350 Rated Capacity Limiter (RCL) monitors various crane functions andprovides the operator with a continuous reading of the crane’s rated capacity. The readingscontinuously change as the crane moves through the motions needed to make the lift. If a non-permitted condition is approached, the RCL is designed to warn the operator by sounding anaudible alarm and illuminating a warning light.

During crane operation, The RCL provides the operator with information such as: the selectedoperating mode, main boom length, main boom angle, jib length, jib angle, and the total loadbeing lifted by the crane. The total load is defined as all weight at the end of the hoist line,which includes hook block, load, rigging, etc..

This manual describes the function, operation, and maintenance of the PAT DS 350 RatedCapacity Limiter (RCL) System for Link-Belt Lattice-Boom Cranes.

This system assists the crane operator in promoting safe and efficient operation by monitoringcrane loads and by warning the operator of approaching overload conditions. Always refer tooperational instructions and load charts provided by the crane manufacturer for specific craneoperation and load limits.

2. WARNINGS

• The PAT DS 350 Rated Capacity Limiter (RCL) is an operational aid which warns a craneoperator of an approaching overload and over hoist condition which could cause damageto equipment, property, and/or injury to the operator or bystanders.

• This device is not, and shall not be a substitute for good judgment, experience, and the

practice of accepted safe crane operation. • The operator is solely responsible for the safe operation of the crane and must observe

and obey all warnings and instructions supplied by PAT and the crane manufacturer. • Prior to operating a crane, the operator must carefully and thoroughly read and understand

the information in this manual and the crane manufacturer’s manual to ensure that theoperator understands the function and limitations of the RCL system and the crane.

• Proper operation of the RCL System is dependent upon proper inspection, maintenance,

and observance of the operating instructions set forth in this manual.

3. SYSTEM DESCRIPTION

The PAT DS 350 Rated Capacity Limiter (RCL) System consists of a central microprocessorunit, operator’s console, and component sensors for angle, load, and anti-two block (A2B)condition. The system uses angle sensors to measure boom and jib angle, if applicable. Thehoist line tensiometers (lineriders) measure the load. And the A2B switch senses anapproaching a two block condition.

The system operates on the principle of comparing real to reference data. The real data issupplied to the central unit by sensors and the operator’s input settings, such as: operatingcode, hoist selection switch, and reeving switch. The reference data (i.e. crane capacitycharts, geometry) is supplied by the crane manufacture and stored in memory chips in thecentral processor unit. The microprocessor evaluates the real data (sensors and operatorinput) to determine an operating mode. The operating mode determines the reference datarequired to calculate permitted operating limits. When limits are exceeded, warning signalsare generated and viewed at the operator’s console. Note the difference between operator’scode and mode; the code is entered by the operator from Appendix, and the system definesthe mode.

1. ANTI-TWO-BLOCK INDICTOR

This symbol will light when the hoist A2B switch opens, indicating that a two-blocking condition is imminent. At the same time, the load hoist up functions willbe disabled.

NOTE: Some Link-Belt machines are equipped with Link-Belt A2B Systems whichincorporate their own horn and/or light.The term “two-block” is a crane term which refers to a condition when the hook block comesinto contact with the boom head. This condition, if not prevented, will cause the wire rope tobreak, allowing the load to fall. Two-blocking can be caused by raising the load into the boomhead, and by lowering the boom without paying out hoist line.

2. PREWARNING LIGHT

This yellow light will illuminate when the load on the hook is between 90% and100% of the crane rating, indicating that an overload condition is approaching.

3. OVERLOAD LIGHT/AUDIBLE ALARM SILENCE BUTTON

A red warning light signals the operator that an overload condition has occurred.The red warning light will illuminate when the total load exceeds the crane ratingor a system error occurs.This button allows the audible alarm to be silenced.

The audible alarm must not be silenced during crane operation, as the operatormay not be alerted by the red warning light alone.

4. TARA BUTTON

This button will tare the net load. (See Section 8.G.) The tare condition willautomatically be canceled, when changing the boom position.

7. GEOMETRY SELECTOR SWITCH

The geometric selector switch determines the information to be shownon the geometry display (4.8.D). Each switch position is identified by anumber (1 to 10) under the window of the control knob. The numbers1,2,3,4,5,9 and 10 refer to the crane symbol (4.8.E) and, if selected,the corresponding arrow will flash to emphasize the displayedgeometric value.

The display (4.8.D) will show one of the following selected switchpositions:

Position 1: main boom lengthPosition 2: main boom anglePosition 3: main boom radius(including jib/extension, if any)Position 4: jib anglePosition 5: boom tip height above ground level (including jib/extension, if any)Position 9: jib lengthPosition 10: Test position. All lamps and characters of the liquid crystal display (LCD) will

illuminate, when this position is selected. Only use this position to check thedisplay.

Selecting position 10 for extended periods of time could cause damage to thedisplay. Only use this position to check the display.

NOTE: Position 4 and 9 will only display correct data if a jib operating mode is selected.During this test, some characters may appear which are insignificant for operating thiscrane.

5. LOCKOUT CONTROLS

5.1 CONTROL LOCKOUT OVERRIDE KEYSWITCH

A key-actuated switch, installed on the central processor unit, enables the operator tooverride the control lockout feature for the load/A2B circuits. Since this switch deactivatesthe lockout function of the RCL system, the following instructions MUST be adhered to:

The bypass switch must be used with discretion. OVERRIDING THE CONTROLLOCKOUT SYSTEM CAN RESULT IN INJURY TO PERSONNEL, DAMAGE TO THECRANE AND/OR PROPERTY. When overriding the system an operator must be fullyaware of the crane capabilities defined by the load charts for the crane.

NEVER use the by-pass switch to either overload or operate the crane out of themanufactures allowable or safe operating range.

To override the lockout features: insert the key, turn the switch to the right, press in, and turnkey back to the left. The key cannot be removed, and system lockouts are by-passed. Toreturn to normal operation simply turn the key to the right and allow the key switch to springout and to the left. The key should be remove and kept in a safe place. The followingillustration shows the keyswitch positions.

15

8. SERVICE AND MAINTENANCE

Daily maintenance of the load moment indicator consists of inspecting:

1. The electrical wiring connecting the various parts of the system. If electrical wiring isdamaged, it shall be replaced immediately.

2. Check the anti two-block limit switches for freedom of movement.

3. Verify that the displayed main boom angle agrees with the actual angle.

4. Inspect linerider sheave. Lubricate as necessary.

Other than correcting the problems identified in the Malfunctions Table and replacing faultymechanical parts and cables, all other repairs shall be performed by PAT Authorized ServiceRepresentatives.



16

9. OPERATIONAL TEST

The operation test will test the Rated Capacity Limiter System and verifies the system sensorsare functioning properly. This test should be completed periodically or anytime there is anindication of inaccuracy.

The following tests shall be performed with care to prevent damage to the machineor injury to personnel. Proper system function requires successful completion ofthese tests before operating the machine.

If the operator cannot clearly see the hook block approaching the boom head, anassistant must watch the hook block.

The operator should be prepared to stop the machine immediately, should theRated Capacity Limiter (RCL) System not function properly by lighting the redwarning light and /or sounding the audible alarm.

Any structural modifications or changes to the crane shall require verification ofthe crane’s RCL System calibration.

1. Start the crane in accordance with crane operator’s manual.

2. Test display using the geometry selector switch.

3. Check that anti-two-block indicator and audible alarm function properly by manually liftingthe weight attached to the A2B switches on the crane. When the weight is lifted, the audiblealarm should sound, the anti two-block alarm light should light. (See SAE J1305 for twoblock warning and limit system operation)

4. Slowly raise the main boom hook block to bring it into contact with the A2B switch weight.

NOTE: If the operator cannot see the load handling device approaching the boom nose, heshall have an assistant (signal person) watch the load handling device. The operatorshall be prepared to stop the machine immediately should the RCL System notfunction properly by lighting the red warning light, sounding the audible alarm andlocking the hoist up function.



17

9. OPERATIONAL TEST (continued)

When the hook block contacts the weight, the red anti-two-block indicator should light andthe audible alarm should sound. NOTE: The hoist up function of the crane will be disabled.Lower the hook block to eliminate the two-block condition.

If the light and audible alarm do not function as described and the crane

movements are not stopped, the system is not working properly. The malfunctionshall be corrected before operating the crane.

5. If the crane is equipped with a boom extension, repeat the test procedure for the boom

extension anti two-block switch. 6. Check that displayed length of main boom agrees with actual length. (Verify operating

code selection before checking length)7. Check that displayed angle of main boom agrees with actual angle. (See SAE J375 for

recommended tolerances)8. Check that displayed operating radius of crane agrees with actual radius. (See SAE J375

for recommended tolerances)9. Check the load display by lifting a load of known weight. (See SAE J376 for recommended

tolerances)

NOTE: Total load include the weight of the hook block, slings, and auxiliary load handlingdevices. Their combined weights shall be subtracted from the listed load capacities asstated on the load capacity chart to obtain the net load to be lifted.

If any of the displays reflects a deviation between displayed and actual values, anauthorized PAT service representative shall be called for repair of the system orverification of the crane’s LMI calibration.
