CAUTION! Do not use elastic stop nut on chain connector pins. Damage to the machine or conveyor chain could occur due to the elastic nuts vibrating off.

IMPORTANT! During assembly, turn two flights upside down (evenly spaced within the conveyor chain assembly) to aid in cleaning return line.

DANGER! When using an additional pulling device (e.g. winch or lifting tackle with adequate load limit) for pulling the conveyor chain, the connection could fracture under the load. You could be seriously injured or killed by the recoiling chain or cable.

Use only approved lifting equipment for connecting pulling devices to the conveyor chain.

IMPORTANT! If old conveyor chain is still on machine, installation can be facilitated by connecting the new conveyor chain to the old conveyor chain via the chain connectors and pulling it through the bottom conveyor pan.

IMPORTANT! Heating connections with a torch may be required to ease the removal of spiral pins and connecting pins.

DANGER! When using an additional pulling device (e.g. winch or lifting tackle with adequate load limit) for pulling the crawler track, the connection could fracture under the load. You could be seriously injured or killed by the recoiling chain or cable.

Use only approved lifting equipment for connecting pulling devices to the crawler track.

______________________________________________________________ A6474X251 SUVT/03 2.21

Overview of safety instructions _________________________________ DANGER! Do not replace relief fitting with standard type grease fitting or high pressure build up will occur in take-up cylinder. You could be seriously injured from high pressure grease.

NOTICE! Field replacement of sprockets is for temporary use only. Replace sprocket properly (see How to install the drive shaft sprockets in this chapter) at next maintenance shift.

DANGER! All adjustable pressures are preset at the factory; do not change the pressure settings from what is stated on the hydraulic schematic located in the hydraulic section of your parts manual.

NOTICE! The hydraulic system must be purged of air anytime a hydraulic hose or component is disconnected or changed. Failure to do so can cause damage to any part of the hydraulic system.

DANGER! Never disconnect a hydraulic hose if the circuit is pressurized.

Release of pressurized fluid can cause serious injury or death to you or other workers.

WARNING! Some procedures must be carried out with the cover of the electrical controller removed and some procedures require the controller to be energized during the tests. It is extremely important that you take all necessary precautions to prevent accidental electrical shock while working within the controller. An MSHA-certified electrician must supervise and inspect all work performed.

IMPORTANT Since communication is both ways, the error codes help to narrow down the cause. Cable problems will most often result in error code numbers 5, 6, or 7. Codes 8-16 are return message problems which usually indicates an internal MCU problem, as wiring must be intact for the outgoing messages to have been received.

_________________________________________________________________ 2.22 BUCYRUS – FULL DIMENSION® Continuous Haulage System

DANGER! Never disconnect a hydraulic hose if the circuit is pressurized or if there is a load on the circuit. If a hose is disconnected while the circuit is pressurized or a load is on the circuit, the load will fall causing damage to the machine or serious injury or death to you or other workers.

________________________________ Overview of safety instructions IMPORTANT Most error codes are common between the fault log and real time codes.

Chapter 6: Technical data IMPORTANT The technical data listed in this chapter is for stock machines only. Customer specials may not be listed.

© BUCYRUS AMERICA, INC.

IMPORTANT! Due to the application of fasteners being subject to great stresses and heavy or extreme vibration, it is imperative that all bolts be applied with an adequate amount of torque. For this reason this list of recommended torque settings for different types and sizes of fasteners used has been compiled.

The tightening torques stated in the spare parts lists have to be observed, as well, for installation and maintenance.

NOTICE! Use only lubrication fluids and greases approved by Bucyrus America, Inc.! These fluids and greases have been tested at Bucyrus America, Inc. and guarantee reliable operation of the mechanical and hydraulic functions of the machine.

IMPORTANT! The lubrication fluids and greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent.

Differently composed fluids and greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient. It may also be dangerous to use lubricating greases and fluids having the same specification base but different origins.

In case of doubt, the manufacturer of the lubrication to be used should be contacted as to the compatibility of the lubrication in question.

IMPORTANT! Bucyrus America, Inc. expressly point out that the approval of the listed products relates only to the pure technical use in our mechanical and hydraulic systems. The responsibility for the constituents used in the hydraulic concentrates lies solely with the respective manufacturer.

IMPORTANT! Be sure to observe the manufacturer’s instructions for use.

NOTICE! When performing maintenance on the continuous haulage system, all used oil and lubricants should be disposed of per your local EPA standards.

________________________________________ Storage and transport

Storage and transport This chapter contains important information on the correct storage and transport of the continuous haulage system.

Observance of the instructions and tips will increase the service life and availability of the system. You will also be able to carry out the transport work quicker and more safely. Careful attention to the points in this chapter will help you to simplify your day-to-day work.

Storage corrosion protection

Components coated with temporary corrosion inhibitor are protected for approximately six months.

© BUCYRUS AMERICA, INC.

Before delivery, the hydraulically operated equipment is operated with a test medium which is drained as far as possible prior to shipment.

The medium remaining in the equipment also protects all the internal parts against corrosion for at least six months.

Storage of the equipment no direct exposure to sunlight

dirt and moisture

Store the equipment indoors or cover with a tarpaulin to protect against direct exposure to sunlight. Store the electrical equipment, electronic components, spare parts of rubber or plastic – such as seals, hoses and tires – and hydraulic fluids only in closed rooms at temperatures of 60° F (15° C) to 77° F (25°C).

Protect the equipment and all spare parts stored outdoors against moisture and dirt, e.g. using tarpaulins.

The mounting surfaces of hydraulic components must be protected against corrosion and sealed with blind plates. Protect the hydraulic plug connectors and the connectors of the electrical cables with the caps and plugs supplied

short-term storage

During short-term storage (approximately 4 weeks) of equipment outdoors, but at temperatures above freezing, electrical components need not be removed. Such components must be particularly protected against excessive temperatures, dirt and moisture.

long-term storage

If the equipment is to be stored more than six months, the hydraulic components must be completely filled with a corrosion inhibiting/frostproofing fluid, e.g. CV 50.

Fill the hollow areas of hydraulic components (e.g. the piston chambers) in horizontal position (ports facing upwards) until they start to overflow. Then seal the ports with plastic or steel plugs.

The equipment must be stored in a well ventilated, dry room. Do not store outdoors.

______________________________________________________________ A6474X251 SUVT/03 3.3

Storage and transport _________________________________________ plastic deformation

In order to prevent plastic deformation of the seal elements, cylinders must be stored in an upright position. Some cylinders must be removed so that they can be stored upright.

random sample inspection

After a storage period of approximately two years, a random sample inspection must be performed to determine whether the measures taken and the method of storage has prevented damage.

On request, the inspection can be carried out by Bucyrus America, Inc.

natural aging

Even with proper storage, seals and hoses are subject to natural ageing. Do not use these parts if they have been stored for more than two years.

HFA fluids

Instructions on the storage of concentrates for hydraulic fluids can be found, if required, in chapter 6 in this operating manual.

Transport Dimensions and weights Observe the transport sheets for the machine and spare parts. They contain information on: ■

dimensions

■

weight

■

lifting points, etc.

Additional information on the dimensions and weights can be found in chapter 6 in this operating manual.

WARNING! Use only load handling devices complying with the technical and legal regulations for the transport of loads.

You could be seriously injured or even killed by falling loads.

Use only suitable load handling devices.

_________________________________________________________________ 3.4 BUCYRUS – FULL DIMENSION® Continuous Haulage System

IMPORTANT! Take care to insure that new supplies are stored separately from existing stock and that removal takes place on the “first in, first out” principle.

________________________________________ Storage and transport Before transport temperatures below freezing

Before transporting the equipment at temperatures below freezing, all hydraulic components operated with emulsion (HFAE or HFAS) must be completely drained and then filled with a corrosion inhibitor/frostproofing fluid (e.g. CV 50).

Transport of equipment at temperatures between -6° F (-21° C) and -40° F (-40° C) is only permissible when certain measures were taken to meet these conditions at the design and manufacture stages. Nevertheless, the individual parts and devices of this equipment must not be subjected to sudden impact loads at such low temperatures and may only be loaded statically or quasi-statically.

© BUCYRUS AMERICA, INC.

During transport of this equipment with floor-mounted vehicles at such low temperatures, measures must also be taken to ensure that the parts and devices are not subjected to sudden impact loads. At very low temperatures and on poor roads, the transport vehicle speed must therefore be limited to a maximum of 15 mph (25 kph) for truck transport. electronic components

Electrical and electronic components must be removed for overseas transport or prolonged storage outdoors unless these components or the complete equipment is protected against harmful environmental influences by a suitable packaging.

The electrical cables remain in the equipment. They must be carefully protected against transport damage and soiling of the connections.

_______________________________________ Adjustment procedures Instructions on the adjustment procedures on the mobile bridge carrier (MBC) It is essential that adjustments be made periodically to the conveyor chain and crawler tracks, otherwise damage can be caused to other parts of the machine or to the assembly itself. Inspect the adjustments at regular intervals.

WARNING! Failure to follow applicable guidelines described in Chapter 2, "Your Safety" before performing maintenance or service on this machine could result in severe personal injury or potential death.

Conveyor chain The conveyor chain is a complete assembly and should be checked for correct tension at regular intervals.

© BUCYRUS AMERICA, INC.

To adjust tension on the conveyor chain with the take-up cylinders proceed as follows (Fig. 58): Loosen bleeder fitting 2 – 3 turns. Attach a grease gun to the grease fitting on the rod end of the cylinder housing and apply grease until desired tension is achieved on both sides. Correct tension is achieved when conveyor chain can be lifted approximately 1” at the center of conveyor with conveyor empty.

Note: Receiving and discharge booms must be fully raised when adjustment is checked. Close bleeder fitting. Remove cover plate. Install or remove the required amount of shims to fill the shim area.

Make certain that the same amounts of shims are used on both sides to prevent chain from stretching unevenly. Spare shims are located in a storage pocket in front of the conveyor chain take-up cylinder.

______________________________________________________________ A6474X251 SUVT/03 5.63

Adjustment procedures ________________________________________ NOTICE! Make certain that the same amounts of shims are used on both sides of the conveyor to prevent chain from stretching unevenly.

Incorrect tension or adjustment can cause premature wear of sprockets and chain. Release pressure on the grease cylinder on both sides by first loosening the grease fitting and then opening the bleeder valve.

_____________________________________________ Troubleshooting Troubleshooting procedures The following section lists possible problems encountered when operating and servicing the continuous haulage system and can aid in locating and correcting these problems.

This section covers basic hydraulic components, with each listed in a trouble-cause-remedy format.

WARNING! Some procedures must be carried out with the cover of the electrical controller removed and some procedures require the controller to be energized during the tests. It is extremely important that you take all necessary precautions to prevent accidental electrical shock while working within the controller. An MSHA-certified electrician must supervise and inspect all work performed.

© BUCYRUS AMERICA, INC.

For maintenance procedures and tests that DO NOT require the controller to be energized, these precautions include:  Before removing the controller cover, remove power from the system by switching the circuit breaker off.  Use insulated gloves and tools where possible.  All connections must be tight and care must be taken to prevent bolts, nuts, washers and other small metal fasteners from being dropped or lost inside the controller. These lost fasteners could cause electrical shorts inside the controller.

For procedures that DO require that the controller be energized while the cover is off:  At no time should you reach inside the controller while it is energized. If it becomes necessary to make adjustments or to replace parts inside the controller, the machine circuit breaker must be turned to the “OFF” position. Once the circuit breaker is in the “OFF” position adjustments or parts replacements can be made.

WARNING! Never disconnect a hydraulic hose if the circuit is pressurized or there is a load on the circuit. If a hose is disconnected while the cylinder is supporting a load, the load will fall.

Trouble, symptom or cause

_____________________________________________ Troubleshooting Error codes The continuous haulage system will display and log error codes. There are two basic types of error codes: ■ ■ Fault log codes

Fault log codes Real time codes

Fault log error codes (Table 12) are sequentially numbered and are stored in the fault log only when they result in a system shutdown.

They normally do not appear on the display. The infra red transmitter is used to access the fault error log.

© BUCYRUS AMERICA, INC.

Communication errors between MCU will result in fault log codes, numbers 5 through 16.

IMPORTANT Since communication is both ways, the error codes help to narrow down the cause. Cable problems will most often result in error code numbers 5, 6, or 7. Codes 8-16 are return message problems which usually indicates an internal MCU problem, as wiring must be intact for the outgoing messages to have been received.

Real time codes

Real time error codes (Tables 12 and 13) will appear on the display immediately. They are almost always displayed on the fourth line replacing “STATUS OK”. They are numbered and transferred to the fault log if a motor shutdown resulted when they occurred.

IMPORTANT Most error codes are common between the fault log and real time codes.

Communication faults

Errors indicating a communication fault or an initialization error (Table 12) on the part of the control station (CST) are not numbered and will appear during normal operation (real time). They will typically appear on the fourth line of the display.

When the CST is powered up, it scans its switches for the “off” position.

If any switches are found to be “on”, including tram joysticks, the CST will not transmit to the machine control unit (MCU), and the MCU will indicate a “CST COMM error”.

The “EST POWER” LED on the CST will not be blinking and the “SW ACTIVE” LED will be constantly illuminated. The “EST POWER” LED must be blinking for transmission back to the MCU. Keep connections between the CST and the MCU tight.

This is most likely due to a cable problem, but may also indicate trouble with the barrier.

___________________________________________ Tightening torques Tightening torques IMPORTANT! Due to the application of fasteners being subject to great stresses and heavy or extreme vibration, it is imperative that all bolts be applied with an adequate amount of torque. For this reason this list of recommended torque settings for different types and sizes of fasteners used has been compiled.

The tightening torques stated in the spare parts lists have to be observed, as well, for installation and maintenance.

© BUCYRUS AMERICA, INC.

NOTICE! Use only lubrication fluids and greases approved by Bucyrus America, Inc.! These fluids and greases have been tested at Bucyrus America, Inc. and guarantee reliable operation of the mechanical and hydraulic functions of the machine.

IMPORTANT! The lubrication fluids and greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent.

Differently composed fluids and greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient. It may also be dangerous to use lubricating greases and fluids having the same specification base but different origins.

In case of doubt, the manufacturer of the lubrication to be used should be contacted as to the compatibility of the lubrication in question.

IMPORTANT! Bucyrus America, Inc. expressly point out that the approval of the listed products relates only to the pure technical use in our mechanical and hydraulic systems. The responsibility for the constituents used in the hydraulic concentrates lies solely with the respective manufacturer.

IMPORTANT! Be sure to observe the manufacturer’s instructions for use.

NOTICE! When performing maintenance on the continuous haulage system, all used oil and lubricants should be disposed of per your local EPA standards.
