General Information INTRODUCTION The operation of heavy mining machinery can be hazardous. To ensure safe operation, operators and personnel must be alert, competent, correctly trained, tested and licensed in the principles, capabilities and correct operating and isolation procedures of the machinery.

This manual is designed to provide the MH-40 Shield Hauler operator with the proper information regarding the machine’s instrumentation, operating controls and general safe working procedures. All operators of this machine must be conversant with the information contained within this manual before operating the machine.

To ensure safe and efficient operation, the MH-40 Shield Hauler must be adequately maintained by the operators and service personnel. To achieve this, the operator’s pre-start inspection procedure contained in Section 6 of this manual must be performed before any use of this machinery is undertaken.

Any abnormalities should be reported immediately to service personnel to avoid costly machine repairs, production downtime and unsafe operation of the machine.

DESCRIPTION The MH-40 is a 40000 kg high capacity Shield Hauler. It has been designed for lifting and carrying heavy pieces of equipment and machinery in underground coal mines. Its main function is carrying and placing of longwall equipment and shields. The machine comes standard with a set of fork tines and winch for this purpose.

The motive force is provided by a 172 kW Caterpillar 3126 turbocharged four-stroke inline six cylinder flameproof diesel engine package. Flameproofing of the system includes a wet bath exhaust conditioning system complete with exhaust filtration and intake flame traps.

The start system is pneumatic. The Electronic Shutdown System is an intrinsically safe electronic monitoring system. The engine power output is connected to the constant fourwheel drive system via a drive coupling and converter through a four-speed bidirectional power shift transmission to heavy duty axles.

The MH-40 Shield Hauler utilises a wet bath exhaust system complete with a exhaust purifier.

A site specific Risk Assessment is recommended to be conducted before this machine is introduced into service.

Gauge Parameters and Colour Coding GAUGE COLOUR CODE The gauges in the operator’s compartment are colour coded to assist the operator to recognise if the temperatures and pressures are within the correct operating parameters.

During normal operation some gauges may, at times, read outside of the indicated normal operating range e.g. during normal operation, when the operator applies the brake the brake head pressure gauge will drop below the minimum pressure and indicate that the pressure is too low. This is because the pressure is being released from the brakes to allow the springs to apply the brakes. When the operator releases the brake the gauge should then return to the green zone.

RED:

The gauge is indicating an unsafe condition. When this occurs the operator should stop the machine and rectify the problem or have service personnel rectify the problem before placing the machine back in service.

ORANGE: The gauge is indicating a temperature or pressure outside of the normal operating range. The operator should closely monitor the gauge and report the problem to service personnel for rectification.

YELLOW: The gauge is indicating a temperature or pressure below the normal operating range. This will not cause immediate damage if operated for short periods. Report to service personnel for rectification if machine continually operates in this area.

GREEN:

The gauge is indicating that the temperature or pressure being monitored is within the normal operating range.

CONTROL LOCATIONS COMPARTMENT DOOR The compartment door must be closed and locked after entering the compartment before the park brake button can be released and the declutch cylinder deactivated.

Never use the door to apply the park brake. Always manually apply by pressing the park brake button and ensure the brake head pressure gauge reads zero. The steering pressure will automatically bleed down, never assume the steering pressure has bled down unless the steering pressure gauge reads zero.

When the door is open the machine cannot be operated, as the park brake will be on and the transmission will be declutched. There is a roller cam valve in the door lock that needs to be activated to release the park brake. Also the brake system pressure is dumped with the door open. The engine will run with the door open.

TRANSMISSION GEAR CONTROL LEVER The transmission gear control lever has four positions, first, second, third and fourth.

Shifting to a higher or lower speed may be made at full engine RPM. The transmission in the machine is modulated. This prevents severe shocks being transmitted through the drive train when the transmission is shifted between gears.

TRANSMISSION DIRECTIONAL CONTROL LEVER A directional control lever controls the transmission. This lever has three positions, forward, neutral and reverse. The engine should be at low idle when the transmission is shifted from the neutral position to either forward or reverse direction.

The transmission must be placed in the neutral position for the starter motor to engage when starting the engine.

If the engine starts when the transmission is not in neutral, the machine should be tagged out of service until the problem is rectified.

PARK BRAKE BUTTON The park brake button has two positions and it is held in the release position by pilot air pressure. By pushing the button inwards, the park brake is applied, and by pulling the button out the park brake will be released. The park brake cannot be released until the system pressure is sufficient to overcome the spring force of the brake control, it also will not release unless the door is closed (there is a interlock valve inside the door lock which needs to be activated to release the park brake).

If the engine shuts down the park brake will automatically apply itself by dumping the pilot air pressure via the low engine oil pressure valve. The brake head pressure gauge must read zero when the brake is applied.

Never use the door interlock to actuate the park brake when exiting the machine. If there is a malfunction on the door interlock system, the park brake could possibly not apply when exiting the machine and the machine could run away resulting in serious damage or injury.

The park brake must be applied for the starter motor to engage whenever an engine start is required.

FOUR-WAY JOYSTICK CONTROL LEVER This lever has five positions, tilt back, tilt forward, lift, lower and hold. Pushing the lever to the right tilts the lift arms back for loading and tramming. Pulling the lever to the left tilts the lift arms down for unloading. Pushing the forward lowers the lift arms. Pulling the lever back raises the lift arms. The lever is spring centred to the hold position.

Two functions may be engaged at the same time by pushing the fourway joystick control lever at 45° in the direction of the two required functions.

NO. 1 - TWO-WAY HYDRAULIC CONTROL LEVER There are two hydraulic two-way control levers fitted to the machine. The first lever closest to the operator is used to auxiliary hydraulic power take off fitted to the rear of the machine.

This lever has three positions, up, down and hold. The lever is spring centred to the hold position.

NO. 2 - TWO-WAY HYDRAULIC CONTROL LEVER The second lever, furthest from the operator, is used to control the winch. This lever has three positions, up, down and hold. When operating the winch, the down position winches the rope in and pulling the lever up winds the winch rope out. The lever is spring centred to the hold position.

OPERATOR’S SEAT On the operator’s seat the height, backrest tilt and seat suspension are all adjustable. The controls for these functions are beside the seat.

ACCELERATOR PEDAL The accelerator pedal is connected to the engine fuel pump governor via a hydraulic slave and master cylinder system. When the accelerator pedal is depressed the engine speed increases. The accelerator pedal is spring returned so that when pedal pressure is removed, the engine returns to low idle.

Always keep the operator’s compartment clean. Dirt, etc. can build up under the accelerator pedal restricting its movement.

BRAKE PEDAL The brake pedal when depressed applies the brakes on the front and rear axles. There are four liquid-cooled Posi-Stop brakes located internally in each axle. Whenever possible use the engine compression to slow the machine on a grade or decline by selecting a lower gear and driving the machine using engine revs.

Do not ride the brakes while tramming the machine.

If the engine should stall, the machine is fitted with fail-safe brake system that will fully apply the brakes. The operator can apply the brakes at any time following an engine stall to immediately bring the machine to a controlled stop.

Always keep the operator’s compartment clean. Dirt, etc. can build up under the brake pedal restricting its movement.

STEERING WHEEL The steering wheel controls the flow of hydraulic oil to the steering cylinder via an orbital steering valve. As the cylinder strokes, the machine articulates to the left or to the right.

Turning the wheel anti-clockwise articulates the machine towards the operator. This effectively turns the machine to the left in the forward direction (lift arms end).

Turning the wheel clockwise articulates the machine away from the operator. This effectively turns the machine to the right in the forward direction (lift arms end).

The machine will turn in the opposite directions when travelling in forward and reverse. Operator training and familiarity with shield hauler operation is important to ensure that collisions are avoided.

If the engine should stall, the machine is fitted with a system that will dump the steering pressure. The operator can steer the machine via a 6 litre back up accumulator at any time following an engine stall to immediately bring the machine to a safe controlled stop.

If the door is opened or the park brake is applied, the machine is fitted with fail-safe steering system that will immediately dump the steering system pressure. This is to protect the operator or personnel from being crushed in the articulation area. Steering cannot be used until the door is shut and latched and the park brake button pulled out to the released position.

The machine is designed to travel in both forward or reverse direction with equal ease and performance.

The transmission is controlled by a directional control lever and a gear control lever.

The machine has the same gear ratios in forward and reverse. This is to provide equal speeds and performance in each direction.

The engine should be at idle and the machine stationary when either forward or reverse gears are selected.

Always start in the low speed and shift into the next higher speed as the machine accelerates and as conditions permit.

Do not coast the machine in neutral. Excessive speed may result in an uncontrollable runaway.

6.

Use the transmission to slow the machine whenever possible, as this avoids excessive brake wear.

Do not downshift the transmission unless the machine is travelling at a speed suitable for the lower range.

Always ensure that the transmission control levers are fully shifted.

7.

8.

Shifting from one range to another can be made at any time conditions permitting.

Momentarily decrease engine revs when selecting a lower gear.

If the transmission should overheat: a. b. c.

Stop machine in a suitable place and apply park brake.

Select neutral and run the engine at ½ speed until the oil temperature has returned to a safe operating level.

If this does not work follow the shutdown procedure and advise the service personnel.
