6.3.3 THE RADIO RECEIVER UNIT (Pict.10)

The radio control version unit (3) is externally equal to the remote control version, internally, it includes the electronic system that manages machine logic and radio module and works as a receiver; a safety system prevents other transmitters from entering the system since it only recognizes its matched keyboard (transmitter) through the RFID code (radio frequency identifier). The European version (868 MHz) includes an antenna that is applied to the electronic units through a connector, it enhances the medium/large range reception field (considering the 868 MHz transmitter reduced power). A supplementary unit (7 function radio) is available upon request; it is similar to the main one and it activates

easy to handle even if exposed to extreme conditions.

6.3.5 THE KEYBOARD – RADIO TRANSMITTER (Pict.10)

N.B. Never let the crane work with disabled emergency button.

WARNING When the cable keyboard is not being used, it must be disconnected from the connector located on the guard aside the unit where the protection cover will be screwed. Press the mushroom button of the cable and radio keyboards after their use and before storing them on a protected and safe place. The radio keyboard batteries last from 12 to 24 hours depending on their use. It is suggested to let the batteries discharge until they are completely flat before starting a new recharge cycle.

6.5.1 KEYBOARD DIAGNOSTIC SIGNALS

The following signal devices are found on the radio keyboard: -a beeper -a green led

Beeper signals:

Radio connection keyboard: - a brief signal (beep) indicates that the keyboard is powered (through the emergency button) -a long signal (beep) indicates that the RFID code (radio frequency identifier, exclusively used by

authorized workshops) self-learning procedure has been activated. -four brief signals indicate that the keyboard has switched to energy save mode or that battery charge is

not enough. Cable connection keyboard (serial): -

6.5.2 DISPLAY MESSAGES

As previously explained, the electronic control unit is fitted with a 3 digits display showing messages which help the operator understanding if everything is working properly, the operating state and the functioning of its electrical components. The operator, when led by an expert or following basic operations, can actually read on such display different messages helping him locating possible electrical anomalies on the system. This is a great help for searching and identifying possible faults, preventing useless and unsuitable interventions by the after-sales service. Against possible displays of error messages, the operator is requested to contact the Technical After-Sales Service.

6.5.3 NORMAL DISPLAY MENU

When switching on, after a sequence of messages on the display this must show:

When carrying out whichever movement by selecting the function it must appear:

When the overload condition is almost reached the display shows:

When the crane goes gets locked by the LLD (overload) the display shows:

In this case you have to carry out the manoeuvres allowing the overload reduction, i.e.: extension re-entry or winch lowering. The boom might be blocked on maximum lift position on some crane models, even without load. To be able to descend with the lifting cylinder, it is necessary to select the extension insertion or the winch descent and immediately afterwards the boom descent followed by the proportional button.

In case of pressure gauge (pressure transducer) signal absence

Moreover, the system can show the following error messages, which can be displayed when operating or trying unsuccessfully to operate.

The messages and relevant meanings are the following: “O”xx followed by the solenoid valve abbreviation. It means open circuit detected on the solenoid valve in object.

Examples: Open circuit alarm on solenoid valve EV3B.

7 OPERATING INSTRUCTIONS

7.1 GENERAL ATTENTIONS

The crane must be used exclusively by qualified and skilled operators. They must know location and function of every control, instruments, indicators, lights, plate and sticker.

• Stay away from the outrigger beams when they are pulled in, to avoid crushing hazard between them and the truck parts.
• When the work is over make sure that the outriggers beam are locked in rest position and the shut-off valves are closed. Lack of doing this may result in serious danger if these parts come out whilst traveling on road.
• The stickers and plates applied on the crane are necessary to enable a safe usage of the same. Should them be no longer readable, replace them as soon as possible with new ones.
• Always disconnect the power take-off before driving away. If the truck engine turns at high revs, the PTO could be damaged.
• The operator should be someone who is familiar with type of crane and has had some experience with it.

• If the crane is accidentally hit, it has to be checked and tested from the closest authorized installer workshop.
• Check every month the state and correct functioning of all the parts subject to wear: pins, valves, hoses, sliding pads and bushings, etc. If necessary replace with genuine spare parts.
• It is absolutely forbidden to alterate the hydraulic circuit and open the safety seals. Failure to comply will cause automatically the voiding of any warranty on the product. Valves adjustments or setting must be done only by authorized installer workshops.
• Overheating of hydraulic oil may burn the sealing parts and alterate the oil itself. This can be caused by an excessive oil flow of the pump or by repeated stroke ends of the cylinders.
• Check that the pump supplies the control valve with the oil flow suggested in our technical specifica

ATTENTION

The outrigger beams are in their working position when the yellow band existing on every beam can be entirely seen.

• Lower to the ground the bearing pads of the outriggers jacks, one at a time, acting as follows:

Hydraulic jack (Fig. 15) Open the shut-off valve (1) to allow the lowering to ground of the cylinder’s pad and rod (2). The valve is open when its lever is on position “A”. Operate the corresponding lever of the control valve until the pad reaches the ground. Avoid to lift the truck off the ground unloading the vehicle suspension, this reduces greatly the stability of the truck. Then, turn again the valve lever to its previous “C”closed position.

Swinging hydraulic jack (Fig. 16) When swinging jack are fitted, before operating the shut-off valve (1) make sure that the jack (2) is in vertical position, with its pad (3) oriented downward, its pin (4) secured with the retainer spring (5). If not, take off the pin, turn the jack downward and then lock in the working position in the aforesaid way. Then open the valve

(1) as already explained (hidraulic jack), operate the corresponding lever of the control valve and lower the pad to the ground as described before. When duly positioned, close the valve (1) as described.

ATTENTION

When turning the swinging jack and removing its pin, be careful and hold it up, to prevent it from falling down because of gravity , resulting in damage or injuries.

• Repeat this sequence of operations for the outrigger jack on the other side of the truck and for every other jack fitted on the truck. Make sure that the vehicle is level, in order to have a good stability. Maximum allowed angle is 3°.

IMPORTANT

Proper leveling has to be checked by means of a level instrument fitted on the truck.

7.3 OPENING THE CRANE

• Starting from the crane in rest position, operate the switch of „boom hoist up“ on remote control. When the boom is roughly horizontal or in any case, higher than vehicle sides or other existing obstacles.
• Then operate the switch “crane swing”, to direct the boom in the desired direction.
• Then operate the switch “boom section extend” until the hook has reached the required position.

7.4 CLOSING THE CRANE

Closing the crane into rest position is performed by carrying out the opposite movements to those made to open it, taking special care , at the end of the operation there are no parts protruding from the truck size.

maximum height allowed by the law, it could hit bridges and other obstructions

7.7 MAIN ERRORS OCCURRING WHEN OPERATING THE CRANE

Because of lacking of care or of adequate instructions, some dangers may occur during crane operation. Most common errors are:

• Slinging of loads exceeding the crane capacity: always check their actual weight not to overload the crane or the winch. Special care has to be taken when handling big loads, when free they can remain hanging on the crane and result in damages and accidents.

• A sudden stop when lowering a load. This creates high forces of inertia on the crane structure with relevant dangerous overload.
• Hitting the rope where the load is suspended, overload is generated.
• Side pull, dragging the load on the ground. All these operations originate strong overloading forces on the crane.
• The outriggers are badly positioned or the ground is not firm: in both cases the truck tilts and could tip over.
• Working with strong wind or wind gusts

8 PUTTING THE CRANE INTO SERVICE

8.1 TEN RULES FOR THE PERFECT CRANE OPERATOR

Always comply with the following ten basic rules:

1 -When approaching the crane for the first time, become on familiar terms with it, executing all the manoeuvres the crane can perform during working. Carefully read all the prescriptions of this manual and execute step by step the activities hereby described to be sure of the correct under standing.

In the crane with PTO-driven: wait for some minutes with the pump running at no load before operate any crane movement.

8.4 CRANE PROTECTION AND STORAGE

8.4.1 Short shutdowns

Wash and clean the crane, lubricate all the parts provided with grease nipples and the slewing system.

ATTENTION

Never wash the crane with chemical products or high pressure water jets, as they can cause the detaching of the stickers water entering inside the electrical components and the slewing case.

8.4.2 Long shutdowns

Same precautions as above and, moreover:

• apply protective oil on the entire crane surface
• cover the crane using a plastic curtain against rain etc.
• store in a dry place, under roof
• disconnect the connections to the truck battery.

9 MAINTENANCE

9.1 WARNINGS

• Do not wear rings, wristwatches, jewelry, loose-fitting or hanging clothing such as ties, torn garments, ordinary shoes, unbut toned jackets or un-zipped overalls, which could get caught up in the moving parts of the crane. Instead, always wear approved accident-prevention clothing such as protective helmets, anti-slip shoes, anti-noise headphones, protective glasses, and reflective jackets with bre athing apparatus. Consult your employer concerning current safety regulations and accident-pre
• Wear protective glasses with side shields to protect your eyes when using compressed air for clea ning the machine parts. Do not allow the pressure of the air to exceed 2 bar (29 psi).
• The access steps or platforms in the workshop or where the crane is operated must be built accor ding to current hazard avoiding regulations.
• Never use petrol or thinners or other flammable liquids or detergents. Use instead authorized com mercially sold cleaning products which are granted to be non-flammable and non toxic.

DANGER

of fire or scald It is forbidden to use naked flame as lighting device when carrying out checks or looking for leaks in the machine.

• Do not lubricate, repair or carry out settings on the crane when it is working, unless this is expressly required in the instructions of the Operator’s/Maintenance manual.

9.6 WIRE ROPE

9.6.1 WIRE ROPE INSPECTION

Each day and before use, inspect the wire rope for the following conditions:

1	-Kinking (Sharp bends)	6	-Rope diameter loss
2	-Crushing	7	-Rope strand	uneveness
3	-Unstranding	8	-General corrosion
4	-Birdcaging	9	-Broken strands
5	-Core protrusion	10	-Cut strands

DANGER

the rope eye for abrasion, corrosion and broken wires.

Inspect the wire rope monthly as follows:

1 -The entire length of the rope

2 -The wire rope eye

9.6.2 ROPE REPLACEMENT

It is extremely difficult to determine the exact time for replacement of wire rope since many variable factors are involved. Proper determination of the condition of a wire rope depends upon the good judgement of an experienced person in evaluating the remaining strength in a used rope after allowance for deterioration disclosed by inspection. The following reasons are sufficient justification for consideration of rope replacement: 1-Six randomly distributed broken wires in one rope lay or three broken wires in one strand in one rope lay.

9.6.3 WIRE ROPE LUBRICATION

Wire rope is lubricated during manufacturing so the strands, and individual wires in strands, may move and adjust as the rope moves and bends. A wire rope cannot be lubrificated sifficiently during manufacture to last its entire life. Therefore, new lubricant must be added periodically throughout the life of a rope to replace factory lubricant which is used or lost. The surface of some ropes may become covered with dirt, rock dust, or other material during their operation. This covering can prevent field applied lubricants from properly penetrating into the rope. Therefore, these ropes should be cleaned before being lubricated. The lubricant applied should be light bodied enough to penetrate to the core of the rope. Lubricant may be applied effictively by various methods. It may be dripped on, sprayed on, or put on by brushing, but in any case it should be applied at a place where the rope is being bent, such as at a sheave. It shold be applied at the top of the bend, because at that point the strands are spread by bending and are more easily penetrated. The service life of rope will be directly proportional to the effectiveness of the method used and amount of lubricant reaching the working parts of the rope. A proper lubrificant must reduce friction, protect against corrosion, adhere to every wire and be pliable and not crack or separate when cold and yet not drip when warm.
