ACCIDENT PREVENTION REGULATIONS FOR ELECTRICALLY POWERED SHOVELS

The safety and accident-prevention regulations valid in the respective country must be observed.

The following requirements are based on extracts from the German accident prevention regulations "Electrical Systems (BGV A3)".

The installation, modification and repair of the electromechanical component of electrical systems and components must be delegated only to qualified electricians or firms employing such experts.

A "qualified electrician" in the context of this regulation is a person who, on the basis of specialized training, know-how and experience as well as knowledge of the relevant regulations, is in a position to judge the extent of the work assigned to him and to recognize any potential hazards.

The machine owner/contractor must inform all persons working on electrical installations and components or in the vicinity of components conducting electricity during operation, or who are responsible for the operation of electrical systems, of the potential danger of electricity and must instruct them on the accident prevention regulations relevant to their work. Instruction in safety measures is to be repeated at intervals appropriate to the operating conditions. If necessary, special working regulations must be displayed.

The shovel and its electrical systems must be adequately protected against other potential hazards of electricity, e.g. fire and explosion.

Electrical systems and components must be protected against electric shock in the case of a fault, e.g. short circuit to exposed conductive part.

Any parts of the electrical system conducting current when in operation must be housed in lock-up switchgear cabinets. Hazard warning signs are displayed on these lock-up cabinets.

Voltage Hazard

The switchgear cabinets must be secured against unauthorized opening. The key must be kept by the electrician in charge.

Electrical systems and components must not be used unless they comply with the operational and local safety requirements. They must be in an orderly state and must be kept in such a state.

Any defects or malfunctions occurring in electrical systems or components must be reported to the electrician in charge.

Before switching on any systems, the shovel operator must check that no one is working on the machine or its electrical systems.

The heavy-duty power cable must never be driven over, buried or ripped away. The shovel equipment must never be set down on the power cable. When the shovel is being moved, the cable must never be pulled or dragged over the ground.

Whenever work is being carried out on electrically powered shovels, the general rules of engineeringespecially those concerning low and medium voltage - must be observed. Regulations such as those issued by the German VDE, e.g. specification VDE 0100, should be observed. Observe all the related laws and rules in your state or country.

Before commencing any work on electrical systems and components, the electrician in charge (or an electrician appointed by him) must switch the power off all circuits and lock them in the OFF state as follows:

Switch voltage OFF all systems.

Check with voltage detectors that all systems are voltage-free.

Lock switches/systems to prevent them from being switched ON.

The above procedures must be carried out in the given sequence.

The machine contractor must provide all the necessary protective equipment and adopt the necessary safety procedures. He must ensure that the safety equipment is used and the safety procedures observed.

The shovel operator and all personnel working on the shovel must use the protective equipment and carry out the specified safety procedures. It is absolutely forbidden to work on any systems or components while they are conducting current. Fatal injury can occur.

If work has to be done in special cases on systems or components conducting current, appropriate safety measures must be taken. Work must not be done on "live" systems and components except by the electrician in charge. The machine contractor must also be notified.

The shovel and its electrical systems must not be switched on again until the above safety procedures have been cancelled and all working areas are prepared for the resumption of operations. Start-up can be ordered only by the person in charge (qualified electrician). Time-based switch-on agreements are absolutely forbidden.

Safety instructions for shovels with electric motor

Before carrying out any maintenance and repair work on the electrical system, the following precautions must be taken:

In the transformer station

Switch off the supply voltage

Lock the safety device preventing switch-on; apply a warning sign

Check that the electrical system is off circuit and dead

Connect to earth and short-circuit

Protect adjacent and live parts against accidental contact

On

The Shovel

Switch off the switch-disconnector

Lock the safety device preventing switch-on; apply a warning sign

Remove the cover

Check that the electrical system is off circuit and dead

Connect to earth and short-circuit

Slide the partition into the disconnector housing

Fire And Explosion Hazard

Prior to commencing work, obtain informationon the national and corporate rules for the prevention of accidents. Pay particular attention to hazards caused by combustible and easily flammable substances.on the safe handling of the fire extinguishers to be used.

Avoid smoking and open fire on, next to and below the shovel.

Combustible and easily flammable substances or liquids increase the fire and explosion hazard. Do not store or handle any flammable substances during operation.

Clean the shovel thoroughly, if possible, with a steam jet (rubber parts and electric components with compressed air - refer to information label), when, for example, oil, grease, fuel or cleaner was spilled.

Such substances may spontaneously ignite if they get into the vicinity of hot units or objects such as turbo superchargers.

Even battery gases can ignite in open flames or fire. Avoid parking the shovel in places where combustible substances such as coal dust or tar are present.

open or smouldering fire may occur.

Remove the shovel from such an area where combustible or easily flammable liquids have spilled from the shovel onto the ground.

Flying sparks (caused by welding, flame cutting, grinding, electrical short-circuit) may cause fire on the ground that can spread to the shovel.

Place suitable fire guardings (fire barriers) if open fire or flying sparks cannot be avoided during repair work.

Apply special protection to cables, cable ducts as well as to hose and pipe lines.

If necessary, also cover the ground with fireprotective blankets. Ensure sufficient ventilation.

Clean the shovel before starting a job.

Do not keep any fire extinguishers that are not suitable or have not been tested.

Do not extinguish flammable liquids with water. Use: dry-powder, carbon-dioxide or foam extinguishing compounds. When getting into contact with burning substances, the fire-fighting water would abruptly evaporate and distribute the substance such as oil over a wide area. Water causes short-circuits in the electrical system thus possibly entailing new hazards.

Danger To Life

Call the fire brigade. Have all your welding, flame cutting and grinding work approved.

Undercarriage

The undercarriage of the hydraulic shovel serves as a stable base and for travelling. The crawler tracks are driven hydraulically with oil motors and travel gearboxes. Undercarriage and superstructure are connected by means of a slewing ring.

Superstructure

The superstructure accommodates the drive and part of the hydraulic and electrical equipment.

Drive

The drive unit comprises electric motor, pump drive gearboxes, hydraulic pumps, hydraulic cylinders and hydraulic motors.

Hydraulic system

All working and travelling movements are performed hydraulically. The movements are controlled by servovalves. The working commands are initiated by hand and transmitted to the valves via control circuits. The oil supply from the superstructure to the undercarriage is ensured by the rotor. The hydraulic system is overload-protected by pressure-relief valves. The hydraulic pumps are supplied with oil from a hydraulic reservoir.

Pump Managing System (PMS)

The Pump Managing System (PMS) with overlimit regulation ensures optimum utilization of the installed or preset engine power. The electronic pump demand control prevents the machine from demanding more hydraulic power than the electric motor can furnish. A microprocessor ensures that the hydraulic output power of the pump is optimally suited to the actual operation conditions.

The PMS box (load-limit regulator) is installed in a control cabinet in the operator's cab.

Stored Program Control (SPC)

The SPC controls the functions: Switch on electric motor, Switch off electric motor Stop, Central lubricating system, Further auxiliary functions.

Further information is given in the Service Manual “Stored-program control”.

Control Management System (CMS)

The CMS is an electrohydraulic servocontrol. Together with the PMS, it provides for optimum interaction between drive hydraulic circuit and working movements.

The required working movements are recognized by microcontroller-assisted scanning of the operating elements (hand levers, pedals) and transmitted to electrohydraulic valves. In the system sequence, the drive regulation is first activated to provide hydraulic working energy. Only then are working movements enabled. Further information is given in the Service Manual.

Demand control / Zero-flow regulation

In the fine-control range, swivelling of the hydraulic pumps, and thus the variation of oil flow, are proportional to control lever and pedal valve travel. This means that during the work, the pumps supply only as much hydraulic oil as required to perform the working movement. In the neutral position of the control levers, the pumps are automatically swivelled to zeroflow.

These special features offer the following advantages: minimum power losses, reduced temperature of the hydraulic oil and greater service life of hydraulic pumps and electric motor.

Board-Control-System (BCS)

The BCS is a data-evaluating and dataprocessing system whose function is to collect, evaluate and store data about the shovel's operating status and to display these to the operator. The BCS is based on a micro-processor. The measured values (actual values) supplied by sensors and transducers installed in the shovel are compared to preset nominal values. Out-oflimit conditions are displayed in the form of error messages in the cab.

Critical operating conditions are additionally indicated by optical and acoustic warning signals. Further dedails are set out in the Board-ControlSystem operating instructions.

Power supply

The electric power is supplied to the shovel through the drag cable (1, Fig. 2-3:) and connection box (3).

The drag cable is guided by a cable guide (2). The power is then transmitted via the slip ring assembly (4) to the circuit breaker in the switchgear cabinet (Fig. 2-4:).

The drag cable can be wound on a cable reel (optional).

Signs

Warning and instruction signs

Observe the warning and instruction signs attached to the machine.

Keep the signs legible and clean. Replace signs immediately if they have become illegible.
