General Information

1 GENERAL INFORMATION

The PAT Load Moment Indicator

(LMI) 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 Load Moment Indicator 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 LMI 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 350 Load Moment Indicator 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.

2 WARNINGS

The LMI is an operational aid that warns a crane operator of approaching overload conditions and of overhoist conditions that could cause damage to equipment and bodily injury.

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 the operation and limitations of indicator and crane are known.

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 manual.

The LMI can only work correctly, if all adjustments have been properly set. For correct adjustment, the operator must 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 LMI has to be ensured before starting the crane operation.

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

Operator's Manual DS 350 / 1319

3 SYSTEM DESCRIPTION

The PAT Load Moment Indicator DS 350 consists of a central micro processor unit, operating console, length/angle sensor, pressure transducers, and anti-two block switches.

The system operates on the principle of reference/real comparison. The real value, resulting from the pressure measurement is compared with the reference data, stored in the central processor memory and evaluated in the micro processor. When limits are reached, an overload warning signal is generated at the operator’s console. At the same time, the aggravating crane movements, such as hoist up, telescope out and boom down, will be stopped.

The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and dimensions are stored in memory chips in the central processor unit. This data is the reference information used to calculate the operating conditions.

Boom length and boom angle are registered by the length/angle sensor, mounted inside the cable reel which is mounted on the boom. The boom length is measured by the cable reel cable which also serves as an electrical conductor for the anti two-block switches.

The crane load is measured by pressure transducers attached to the piston and rod side of the hoist cylinders.

The interactive user guidance considerably simplifies the input of operating modes as well as the setting of geometry limit values.

3.1 SYSTEM FUNCTION

Upon switching on, the system starts with an automatic test of the LMI system, of lamps and audible alarm. During the test, the LC display shows the initial logo.

If the system was turned off for more than two hours, the setup configuration has to be entered after the system test. (⇒ Chapter 4)

First, the operating mode is determined by an interactive step-by-step interrogation of the rigging states.

Next is the interactive input of the reeving.

Now the LC display shows in symbols all inputs and awaits acknowledgment or cancelling.

Upon acknowledgment of the inputs the system is ready for operation.

General Information

3.2 OPERATING CONSOLE

The console has 3 functions:

• inputs by the crane operator (operating mode, reeving)

• input of geometry limit values and signalization of exceeded limit values

• display of important data and information

The operator’s console is mounted in the crane’s cab in the operator’s field of vision. For a better identification of displays and operating elements, they are continuously backlit during operation.

3.3 CONTROL IDENTIFICATION

This unit contains a display and different controls which are described as follows:

LC-Display

The LC display visualizes graphical symbols, texts and numerical values. Depending on the selected operating mode (setup, limit mode or LMI representation), the corresponding information is indicated on the display. Please refer to the description of the different operating modes for the signification of the individual elements.

Load Moment Limit Light

The red LOAD MOMENT LIMIT LIGHT (2) warns the operator that a rated load condition has been reached. It lights up when the load on the crane reaches the crane load capacity. The audible alarm also sounds when this condition has been reached. The following crane movements will be stopped concurrently: hoist up telescope out boom down

Load Moment Prewarning Light

The yellow LOAD MOMENT PRE-WARNING LIGHT (3) will light up when the load on the crane reaches the defined prewarning area, thus indicating that an overload condition is approaching.

This means for the operator to continue his crane operation with extreme caution.

Alarm Light “Anti-2-Block”

The red “Anti Two-Block Alarm Light” (4) lights up when the anti-twoblock limit switch contacts open, indicating that a two-blocking condition is approaching. At the same time the audible alarm will sound. The following crane movements will be stopped subsequently: hoist up, telescope out, boom down.

Override Key Warning Light

The red OVERRIDE KEY WARNING LIGHT (5) flashes to indicate that the cut-off function of the A2B / LMI system is deactivated.
