A Correct use and application of the truck

ZThe <Guidelines for the Correct Use and Application of Industrial Trucks? (VDMA) are included in the scope of delivery for this truck. The guidelines are part of these operating instructions and must always be heeded. National regulations are fully applicable.

The fork-lift truck described in these operating instructions is a truck that is suitable for lifting and transporting loads.

It must be used, operated and maintained according to the information in these operating instructions. Any other uses are outside the design envelope and can lead to injury to persons or damage to equipment and property. Above all, overloading caused by excessively heavy or unbalanced loads must be avoided. The max. admissible load to be picked up is indicated on the identification plate or load diagram label shown on the truck. The operator must ensure that damaged and/or poorly readable load diagrams are renewed. The fork-lift truck must not be operated in spaces subject to fire or explosion hazards, or in spaces where corrosive or very dusty atmospheres prevail.

Duties of the user: A <user? within the meaning of these operating instructions is defined as any natural or legal person who either uses the fork-lift truck himself, or on whose behalf it is used. In special cases (e.g. leasing or renting), the user is considered the person, who, in accordance with existing contractual agreements between the owner and the user of the fork-lift truck, is charged with the observance of the operating duties.

The user must ensure that the truck is not abused and only used within its design limits and that all danger to life and limb of the operator, or third parties, is avoided. In addition to this, it must be ensured that the relevant accident prevention regulations and other safety-related provisions, as well as the operating, servicing and maintenance guidelines, are observed. The user must also ensure that all persons operating the truck have read and understood these operating instructions.

MIf these operating instructions are not observed the warranty becomes void. The same applies if improper works are carried out at the device by the customer and/or third parties without permission of our Customer Service.

Mounting of attachments: The mounting or installation of any attachments which will interfere with, or supplement, the functions of the truck is permitted only after written approval by the manufacturer has been obtained. If necessary, the approval of local authorities has to be obtained.

Any approval obtained from local authorities does not, however, make the approval by the manufacturer unnecessary.

Trailing and slipping loads: The truck may only be used for trailing or slipping loads for which the truck has been approved.

Design and application

 

 

 

EFG 422-430 is an electric rider-controlled fork lift truck in four-wheel construction

 

with front drive which picks up, transports, and lifts its load outside the wheelbase. It

 

is a cantilevered counterbalance truck which can E due to its load lifting device being

 

located in front of the lift truck E unload lorries and deliver the load on ramps or in

 

racks unimpededly. It can be used to stack and transport DIN 15142 pallets,

 

DIN 15144 lattice box pallet, and other palletised loads.

2.1Truck

Steering (8): When a load is applied to the driver seat the steering is switched to Standby. The steering unit runs at a preset idle speed. Depending on the steering request the steering pump is increased and the travel speed is reduced depending on the steering arc (FCurveControlH). The steering angle is indicated in the display.

Driver seat (2): The driver seat is a comfort seat and the steering column is adjustable. There are storage places for documents or personal belongings of the driver. The MULTI-PILOT combines all hydraulic functions and the travel direction switch in one single lever. The overhead guard (1) is prepared for a cabin installation and thus can be easily retrofitted.

Electric/electronic system: Sophisticated three-phase AC technology enables data transfers with few cables only (CAN bus). Thus we achieve decreased susceptibility to faults caused be broken cables as well as considerably faster fault isolation. The complex TC system (Total Control) is designed for simply, safe, and flexible usage. Depending on the load the driver can select from different operating programmes: from high-performance to energy-saving. Convenient and very fast fault analysis and programming can be performed via PC.

Drive and brake system: The front drive offers ideal traction to the drive wheels at all times.

The hydraulically actuated oil-bath multi-disk brake used a service brake is practically maintenance-free. The encapsulation in the transmission allows applications even in aggressive environments. In addition, the lift truck is generatively braked via the travel motor. Thus the energy consumption is minimised.

After approximately 15 sec standstill of the truck or 1 to 15 sec (adjustable) after the driver seat is relieved the spring-loaded brake engages.

When actuating the accelerator the spring-loaded brake is automatically disengaged.

Hydraulic system: All functions must be executed sensitively, proportionally, and simultaneously (only if this does not impair the safety). For higher efficiency a hydraulic unit and a steering booster motor function separately from each other. The micro pressure filter can be changed from the top (without spilling hydraulic oil).

Lifting mast (7): Our goal is optimising the view. The high-strength steel profiles are narrow, which is especially notable in the three-stage lifting mast with its good view to the fork arms. The same good results are achieved for the fork arm carriage.

The lifting mast as well as the fork arm carriage move on prelubricated and thus main- tenance-free cocked support rollers.

3.4EN standards

Continuous sound pressure:

EFG 422/425k/425 = 70 dB(A)

EFG 425ks/425s/430 = 71 dB(A)

according to EN 12053 as stipulated in ISO 4871

ZThe continuous sound level is a value averaged according to standard regulations, taking the sound pressure level into account when driving, lifting and idling. The sound pressure level is measured at the ear.

Vibration:

EFG 422-430 = 0.45 m/s2

 

According to EN 13059

ZThe swinging acceleration acting on the body in its operating position is, according to standard regulations, the linear integrated, weighted acceleration in the vertical plane. It is determined by driving over bumps with a constant speed.

Electromagnetic compatibility (EMC)

The manufacturer confirms compliance with the limit values for electromagnetic emission and interference immunity as well as testing of static electricity discharge according to EN 12895 and the references to other standards contained therein.

ZElectrical or electronic components and their arrangement may only be modified after written approval by the manufacturer has been obtained.

4.2Truck load diagram

The truck load diagram indicates the carrying capacity Q kg of the truck with the lifting mast in vertical position. The table shows the maximum carrying capacity at a standard load centre distance D (in mm) and the desired lifting height H (in mm).

Example for determining the maximum carrying capacity:

At a load centre distance of D = 600 mm and maximum lifting height H = 3,600 mm the maximum carrying capacity Q = 1,105 kg.

4.3Fork arm load diagram (basic device)

The fork arm load diagram indicates the carrying capacity Q of the truck in kg. In the diagram the maximum carrying capacity for different load centres D (in mm) is shown.

4.4Attachment load diagram

The attachment load diagram indicates the carrying capacity Q of the truck in connection with the respective attachment in kg. The attachment serial number indicated in the load diagram must correspond to the ID plate of the attachment, since the manufacturer must state the carrying capacity specially for each attachment. It is indicated in the same way as the carrying capacity of the truck itself and must be determined accordingly.

The arrow markings (42 and 43) at the

inner respectively outer mast indicate to 42 43 the driver that the lift limitations pre-

scribed in the load diagram have been reached.

C Transportation and commissioning

1Transportation by crane

1

MOnly lifting gear of adequate capacity must be used

(loading weight = own weight + battery weight; see identification plate of the truck).

G Safe parking of the truck (refer to chapter E)

G Fasten hoisting gear at lifting mast crossbeam (1) and at trailer coupling

(2).

MTransporting by crane is only provided for transport for first commissioning. For application conditions that require frequent shipment (changing usage locations) it is required to consult the manufacturer.

MHoisting belts or chains may only be hooked into the top lug of the counterweight and the lugs of the end crosshead (lifting mast).

The lifting mast must be fully tilted back. The hoisting belt or chain at the mast must have a minimum free length of 2 m.

MThe crane hoisting gear must be attached in such a way that it cannot touch any attached components or the overhead guard during lifting.

2Securing the truck during transport

MThe fork lift truck must be properly secured with wedges and restraints during transport on a lorry or trailer. The lorry or trailer must be equipped with lashing rings and a wooden floor. Perform loading with suitably trained specialist staff according to the recommendations of VDI 2700 and VDI 2703 guidelines. Correct dimensioning and implementation of load securing measures is required for every separate case.

ZTo lash down the fork lift truck with the lifting mast installed use the eyes on the top cross beam of the mast and the trailer coupling pin.

Lashing and wedging with the lifting mast installed

ZTo transport the fork lift truck without lifting mast perform lashing across the overhead guard front.

3Commissioning

FCommissioning and instructing drivers may only be performed by appropriately trained personnel.

MThe truck must only be operated on battery current. Rectified alternate current will damage the electronics. Cables connected to the battery (trailing cables) must be less than 6 meters in length.

In order to prepare the truck for work following delivery or transportation, the following operations must be performed:

H Check equipment for completeness.

H Check battery connections and acid level (refer to chapter D, section 6).

H Bring the truck into service as prescribed

(refer to chapter E, section 3).

4Moving the truck with the drive unit inoperative

In order to move the truck without electricity supply, the spring-loaded brake must be disengages as follows:

FBefore the driver leaves the truck with the spring-loaded brake disengaged he

must secure the truck against accidental

3

rolling away.

 

D Set lever (1) to position IDisengage spring-loaded brakeK.

DTurn the steering wheel clockwise until pressure builds up in the hydraulics circuit and the spring-loaded brake is disengaged. (This can be noticed by checking whether the brake pedal functions normally, if the brake is still engaged you feel an immediate resistance). The drive wheels are no longer blocked resp. decelerated by the spring-loaded brake. The foot

brake will still be fully operative. While turning the steering wheel the foot brake must not be actuated.

MPrior to recommissioning the truck by applying power again, lever (1) must be set to the right to ITravel positionK. The truck is now ready to operate in travel position.

Trucks with Multifunction Steering Wheel (o)

D Set lever (4) to the left position IRelease accumulator brakeK

D Carry out a sufficient number of pump strokes with the lever (5) until pressure builds up in the hydraulic circuit and the

spring-loaded accumulator brake is released. The drive wheels are no longer blocked / braked by the springloaded brake.

MBefore starting the truck again with power supply, the lever (4) must be reset to the right in the ItravelK position. The truck can

only operate in the travel position.

5Steering the truck without its own drive system (o)

MThe truck cannot be steered if the steering hydraulic system or the truck electronics are damaged.

To steer the truck without power, apply

6

the steering as follows.

A Turn the EMERGENCY DISCONNECT and key switch off.

A Secure the truck to prevent it from rolling away

A Place a spanner on the hex. bolt (6) and turn the drive to the required steering position.

6Towing the truck

A Connect a tow-rod/towing rope at the trailer coupling of the recovery vehicle and at the truck to be towed.

A Disconnect the battery plug (observe item D3!). A Disengage the parking brake.

FThere must be a person for steering the truck on the driver seat of the truck to be towed. Tow the truck at walking speed!

ZAs the steering booster is not switched on, the truck can only be steered with increased effort.

MFor trucks with a multifunctional steering wheel (o) only authorised persons may only tow the truck out of the hazard area for slow shunting. The truck can only be moved using a recovery truck and a tow bar. The emergency steering must be applied as described in XSteering the Truck without its own Drive SystemY
