PREFACE

GENERAL SAFETY STANDARDS PERSONAL SAFETY n

Always use the personal protective equipment when it is required.

n

Pay attention to the squashing risks due to moving parts, oscillations, not correctly fastened materials when lifting operations are carried out or when the loads are moved.

n

Do not wear rings, watches, jewels, unbuttoned or hanging clothes such as scarves, unbuttoned jackets or smocks with open zips that can get entangled in the moving parts.

n

Never carry out cleaning, lubrication or maintenance operations when the battery is connected.

n

If you use compressed air to clean the parts, wear glasses with lateral guards.

SAFETY IN THE WORKPLACE n

Make sure that all working tools are perfectly efficient and ready to use. Keep the working surfaces clean and free from the deposits that settle on the truck parts and cause damage.

n

Keep sparks, free flames and cigarettes at a distance from fuels or flammable materials such as the gas of the batteries.

n

Make sure that the working area is well ventilated, illuminated, dry and clean. Remove any water puddles or oil spots.

n

Make sure that the lifting equipment, devices or machines can bear the load.

n

Never use petrol, gas oil or other flammable liquids as detergents: use commercial non-toxic and non-flammable solvents.

n

In case the interventions are carried out of the workshop, lay the truck flat and block it. If it is necessary to carry out the work on slopes, block the truck and bring it in a flat area as soon as possible within a certain safety limit.

n

Disconnect the batteries and label all controls in order to indicate that an intervention is in progress.

Block the truck and any equipment to be lifted.

n

Do not carry out any intervention on the truck when the operators are controlling it, except that they are qualified operators and help to carry out the intervention.

n

During towing operations use only the prescribed attachment points and make sure that the pins and/or bolts are tightly secured. Lift and move all heavy components by means of a lifting device of proper carrying capacity. Use the proper eyebolts. Make sure that nobody stays near the load to be lifted.

n

Do not twist chains or metal ropes.

n

Do not use damaged or bent chains or ropes: do not use them during lifting or towing operations.

While handling them always wear safety gloves.

n

Do not accumulate cloths soaked with grease or oil: they represent a risk of fire. Always put them in a closed metal container.

n

The oil must be collected and not be let off in the drain pipes; the industrial oils must be disposed of by specialized companies under the protection of the law in force in every Country.

PREFACE

When welding operations are carried out, it is necessary to use proper accident-prevention protections: protective glasses, helmet, overalls, shoes. The protective glasses must be worn also by the people who do not carry out the works if they stay near a welding area.

Before using the batteries, make sure that the cables are connected to the terminals as described: (+) with (+) and (-) with (-).

Do not short-circuit the terminals.

The gas emanated during a recharge is higly flammable. During the recharge of the battery leave the battery compartment uncovered in order to use a more efficient ventilation and remove the plugs.

Do not check the condition of the battery charge by means of “jumpers” obtained by placing metal objects on the terminals.

Before any intervention check if there are no short-circuit elements.

Disconnect the batteries before acting on the electric system.

For the battery chargers and similar equipment, use only auxiliary electric power supply sources in order to avoid any electric shocks.

A fluid passing through a very small hole can be almost invisible but strong enough to penetrate into the skin; in these cases check the fluid by means of a card or a piece of wood.

To check the pressure of the plant use the proper devices.

BANDS, ROPES AND HANGING ROPES: SUGGESTIONS FOR THE USE n n n n n n n n n n n

Register all used hanging ropes, whose features and data are shown on the identification plate.

Do not use bands, ropes or hanging ropes, whose identification plate has been lost.

Always use bands, ropes or hanging ropes of proper dimensions. As far as the hanging ropes are concerned, take into consideration the lifting angle and the unbalance of the load.

The hooks of the hanging ropes must have a proper size according to the hook of the bridge crane and they must move freely.

Position the load in the hook mouth.

Do not place the load on the point of the hook.

During lifting, do not carry out sudden operations that could tear the ropes and the bands.

Do not carry out lifting operations with twisted ropes and bands.

Knots are forbidden.

Always protect the ropes and the bands when they are near sharp edges.

During the movements without load in order to avoid unintentional collisions or hooking, fasten the hooks to the proper seats and lock them.

Use of hanging ropes with unbalanced load If unbalanced loads must be lifted it is advisable to reduce the carrying capacity of the hanging ropes: n Slings with 2 arms, consider them as the slings with 1 arm. n Slings with 3 and 4 arms, consider them as the slings with 2 arms.

Suggestions for maintenance Check the bands, the ropes and the hanging ropes according to the law in force in order to determine their working conditions.

Carry out the replacement in the following cases: n When the components are deformed, cut or when there are cracks, hollows, notches or abrasions on them. n When the wear of the components is higher than 10% of the initial dimensions. n When the sling is overloaded.

DRIVING TORQUE OF SCREWS, NUTS AND CONNECTORS Before the disassembly of the various parts and of the bolts and screws, read carefully the instructions below.

To tighten the screws use the product LOCTITE 270 in order to ensure the safety of the threaded couplings.

DRIVING TORQUE Nm

Nominal diameter

If it is not possible to loosen the screws because this product is used, do not add extensions to the tools, but heat the area (maximum 50° - XXX farehnheit degrees) in oder to eliminate the effect of LOCTITE 270.

In the above-mentioned cases use a small quantity of LOCTITE 270 in the assembly phase (30% of the connection surface).

The driving torque with which the threaded couplings are tightened is very important to ensure the safety of the truck connection.

The bolts and nuts and the corresponding driving torques are shown in the tables on this page.

PREFACE

INSTRUCTIONS FOR THE INSTALLATION OF HOSES AND CONNECTORS Visual check of hoses and connectors: if one of the following conditions occurs, the hose must be immediately disconnected and replaced:

• • • • • • •

movement of the connector on the hose; there are damage, cuts or abrasions on the surface; hardening or stiffness of the hose, burned parts or cracks due to heat; cracks, damage or corroded parts on the connector; leakages from the hose or connector; the hose has permanent folds, squashed or twisted parts; presence of bubbles, softening and wear of the external surface.

Pre-installation inspection: before installing a hose it is necessary to check the conditions of the pipes. First of all check if the type, the size, the reference code and the length are correct and then make sure that there are no impurities, obstructions, bubbles, external layer peeling-off or other visible defects.

Installation: Do not twist the hose, otherwise it could break due to pressure.

Consider a proper radius of curvature in order to avoid the bending or breaking. If the radius of curvature is lower than the minimum radius of curvature allowed, the life of the hose is considerably reduced.

The pressure can change the length of the hose, up to + 2%. Therefore it is advisable to consider a length which is higher than the required one in order to compensate for such changes.

INSTALLATION AND SETTINGS

DELIVERY OF THE TRUCKS MOD. ALL MODELS

Before delivering the truck, the battery on the control (COMBI and/or MPB) must be set.

Before carrying out this operation, we recommend charging the battery so that it can be used at the maximum voltage.

SETTING PROCEDURE A) When the truck is off, remove the MDI connector (if any) from the control and connect the console adapter on the same connector (B) of control MPB. Turn on the truck and select “CONFIG MENU ADJUSTMENT “ and then parameter “ADJUST BATTERY”.

B) Lower the tiller to disable the main remote control switch and by using the “MULTIMETER” detect the battery voltage on the control by positioning the multimeter prods on the battery cable clamps (B+ - B-).

Set the value detected on the “MULTIMETER” (example 25,2V) on the console on parameter “ADJUST BATTERY”. Turn off the key and turn it on to store the value.

To check if the value of the voltage has been stored, select “MAIN MENU’ TESTER” and then parameter “BATTERY VOLTAGE”, if the value does not correspond, repeat the procedure above-described.

NOTE: If the battery is not completely charged, the battery indicator (MDI) does not reset showing the actual charge value, until the battery is completely recharged.

• When the tiller box board must be replaced • When the proportional push buttons for the lifting and lowering must be replaced (when they are installed)

PROCEDURE Step 1 Move the jumper from position “A” (fig. 1) to position“B” (fig. 3). During the acquisition procedure the jumper must be inserted in the external pins of the board.

Step 2 Turn on the truck (Key ON): the CONTROLLER is in acquisition mode.

Step 3 Rotate slowly the speed control forward up to its end of stroke and then release it slowly by letting it come back to the centre.

Rotate slowly the speed control backward up to its end of stroke and release it slowly by letting it come back to the centre.

Step 4 Remove the JUMPER from position “B” and iinsert it into position “A” (travel condition). Turn off the truck (Key OFF). Wait 30 seconds before restarting the truck (Key ON).

The controls has now acquired the potentiometer new values. Close the tiller box and carry out the test by moving the truck. If the acquisition is not successful, repeat the procedure.

NOTE: A new acquisition is required when “ALARM 78” (Vacc not ok) is activated.

MAST MECHANICS 4.00

CHAIN GREASING

The element that gives a long life to the chains is their lubrication.

Therefore a periodical lubrication with a proper oil must be performed by means of a brush or by means of aerosol cans.The frequency with which this operation must be repeated depends much on the type of work and the environmental conditions, but usually every 500 working hours.

4.01 CHAIN ELONGATION

With the use, the chains tend to stretch.Such elongation can be reduced by acting on the chain tightener.

The maximum reduction of the chain elongation is equal to 2%. When this value is exceeded, the chain must be replaced.

4.02

CHAIN MEASURE

Measure the elongation on more sections of 10 pitches, measured on the most stressed sections. This control must be performed about every 1500/2000 working hours. The measure of the 10 pitches is represented in the table below with also an indication of the corresponding chain. If, before the control, the chains have undergone negligible elongations, lower than 2%, this does not mean the chain has remained intact and without any defect.On the contrary, you can have deformations caused by the stress; therefore it is better to carefully check the whole chain in order to control the wear state of the links, the hinge pins, the chain tightener and the chain tightener pin.

OPERATION The electromagnetic brake, which is fixed on the drive motor, is only a parking brake with STOP or EMERGENCY function and it is a spring-loaded brake.

When the electromagnet is supplied, it attracts the braking plate (ref.4) and releases the brake lining making it rotate freely.

When the electromagnet is no more supplied, the springs push the plate downward on the brake lining enabling the braking.

BRAKING SYSTEM

2.00 BRAKING SYSTEMS There are 3 braking systems:

• Release breaking.

• Inversion braking.

• Emergency and parking braking.

A) RELEASE BRAKING It controls the deceleration ramp when the drive control is released.

B) INVERSION BRAKING It controls the deceleration ramp when the drive control is inverted.

The “inversion braking” called also reverse current braking is consists in reversing the current on the motor by changing the direction of travel when the truck is driving.

The braking current must be adjusted so that the truck can stop within a distance not smaller than the length of the truck.

C) EMERGENCY AND PARKING BRAKING The “emergency and parking braking” is obtained by the electromagnetic brake fixed on the drive motor.

The excessive decreasing of the braking space may compromise the good operation of some components of the truck, since during the braking the current on the motor reaches very high values thus causing (in case of wrong adjustment) an early wear of the brushes, the drive motor manifold and the drive wheel.

H G Fig. 5 After assembling the electromagnetic brake unit, it is necessary to adjust the brake lining before using the truck.

For a good braking the distance between the brake lining and the electromagnet (ref.F fig.5) must be not higher than 0.35 mm. Therefore a feeler gauge of that measure is required.

Keep the three nuts loosened (ref.G fig.5), insert the feeler gauge near a bolt (ref.H fig.5), tighten the fastening screw by means of the Allen wrench (ref.I fig.5) Allen wrench and bring the plate nearer at a distance that allows extracting the feeler gauge with a little friction. Repeat the operation on all three bolts.

Tighten the nuts by means of the open ended spanner (ref.G fig.5).
