NOTE

Select a route that is as flat as possible. Steer the excavator as straight as possible making small, gradual changes in direction.

(42)

Curragh Queensland Mining Pty Ltd is part of Westfarmers Energy 41 Select the direction of travel as follows:

• Forward Travel - Push down on the front of both pedals or, push forward on both of the travel levers

• Reverse Travel - push down on the rear of both pedals or, pull back on both of the travel levers

• Neutral Position - when the travel pedals or, levers are placed in the neutral (central) position, the travel brakes will automatically stop and/or hold the machine

• Left Turn - push down on the front of the left pedal or, push the left travel lever forward

• Right Turn - push down on the front of the right pedal or, push the right travel lever forward

• Short (spin) Turn - push down on the front of one pedal and the rear of the other or, alternatively push/pull both travel levers in opposite directions

WARNING

The travel directions above are described with the track idlers positioned at the front of the excavator and the travel motors at the rear. (If the tracks are

facing in the opposite direction the control movements must be reversed)

Be sure to confirm the position of the travel motors before travelling

(43)

2.4.6 Filling the bucket

Before moving the bucket into the face it should be levelled and lowered to the floor. The bucket can be levelled by pulling/pushing the bucket control lever to the left or to the right.

Once the bucket has reached a point where the floor of the bucket is of a similar angle to that of the material being excavated, lower the bucket to the floor and check the bucket level, adjust the level if required. With the bucket levelled and lowered to the floor, move the bucket arm towards the face to the point where the excavator has

started to labour, at this stage pull the bucket control back towards the operator seat to start to roll (tilt) the bucket slowly until it’s full whilst slowly raising the boom(hoist).

Always keep the bucket floor parallel to the face when digging. When the bucket is full, continue to hoist to the required level while also slewing towards the loading position.

(44)

2.4.7 Working on Inclines (Slopes)

It is usually safer and more efficient to work from the tops of an incline to the bottom (rather than from the bottom up to the top). The weight of the excavator (and gravity) will assist in pushing the load ahead of the blade. You will need to communicate and understand the angle of an incline before you can work on it. Inclines are generally referred to in ratios (e.g. 2:1, 4:1).

2:1, means that if you walk for two metres up an incline you will rise one metre from your starting point. A ratio will also relate to the angle of the incline. The drawings below show the relative steepness of inclines and approximate angle in degrees.

At Curragh, ramp angles are usually referred to in percentages (e.g. most pit ramps are 8%. Dragline ramps are 10% maximum). Highwalls are usually referred to in ratios (i.e. 1:1 or 1:2)

2:1 Slope 27° Off Horizontal 51% 3:1 Slope 18° Off Horizontal 32.5% 4:1 Slope 14° Off Horizontal 24.9% WARNING

Avoid travelling across (right angles) a slope. If you must walk across a slope:

• Keep the bucket close to the ground (.5 – 1 metre)

• Do not swing downward on a slope

(46)

Excavators may tip forward when travelling up or down a slope (dip) always keep the bucket low to the ground (500mm to 1 metre)

Avoid turning on slopes. If you must turn ensure the ground is firm and the slope angle is not excessive. Never traverse slopes of more than 15 degrees longitudinally or 15 degrees across the fall.

It is important to select the correct digging technique with regard to the steepness of the slope.

WARNING

Avoid working across a slope (eg at right angles). If you must work across a slope:

• Start at the top

• Maintain a windrow on the low side of the excavator to provide stability

(47)

EX25/36 2.3 SELECT LOADING METHOD

2.3.1 Loading Tasks – includes both haulers and rear dump trucks.

There may also be times when loading is in conjunction with other type of loading units eg loader.

Loading materials may include:

• Topsoil

• Overburden

• Coal

• Interburden or partings

Whatever type of unit you are loading, you must work with the operator as part of a team by:

• Maintaining communication with the operator of the equipment being loaded. This may be via two way radio, by horn signals (eg one horn

signal by the excavator operator to tell the truck to stop) or visually

using hand signals

• Ensuring the truck is positioned for safe, easy and productive loading

2.3.2 Loading Preparation

• Carry out an inspection of the area where loading is to be carried out for any hazards

• Communicate your movements to any other operators in the area

(48)

2.3.3 Loading Operation

Study the area that the loading operation will be carried out and decide on the best approach to loading eg:

• Develop a plan of how to work the face and the loading method to be employed (eg drive by, through the gate)

• Inspect the area/material to be loaded and decide if any additional preparation is required (eg grader/dozer to prepare floor/bench)

• Set up the loading bench. Check the following as you go:

- keep the bench height as close as possible to the stick length or equal to the gate height of the truck.

- set the angle of the bench to suit the material being excavated. Loose material will need a lower angle while compacted earth may stand near vertical.

• Load trucks using the most productive method (eg drive by, over the

side)

When trucks are fully loaded and the area is clear of other traffic, sound the horn once to signal that loading is completed.

NOTE

Some rear dump trucks have a load weight system, as the excavator operator you should familiarise yourself with the system fitted to the trucks you are loading. The Komatsu system fitted is as follows:

One Green light for a load between 56-67 ton Two Green lights for a load between 67-85 ton Three Green lights for a load between 85-91 ton One Yellow light for a load between 91-96 ton One Red light for a load o ver 96 ton

Do Not Overload

Komatsu 785 Rear Dump Trucks are rated at 85 ton (three green lights)

(49)

2.3.4 Positioning Trucks/Loading Techniques

The excavator operator is the ‘spotter’ and it is his/her role to direct the truck to the loading position. The excavator operator usually has the bucket full and in position so that the truck can reverse under it for loading.

Loading may be carried out using a number of techniques to satisfy safety, job or production needs. Some of the more common techniques include:

• Over the side

• Off the same level

• Through the gate

• Drive by

Factors to consider when setting up for loading include:

• Bench height

• Material stability

(50)

2.3.5 Loading Over the Side

The excavator is positioned parallel to the face with the right track lined up along the cut line.

Trucks are positioned at right angles to the face or they may also be positioned at an angle to the face (see diagram below)

The excavator swings from the dig zone to the left carrying the bucket over the side (rails) of the truck before placing the material in the body of the truck.

The basic operation for loading over the side is as follows:

• The excavator raises the load and positions it at right angles to the face

• The truck operator backs under the bucket

• The excavator sounds the horn when the truck is in the correct position or has reversed back sufficiently

(51)

2.3.6 Through the Gate Loading

Trucks are positioned at an angle to the bench face and facing away to the left of the excavator.

The excavator swings from the dig zone to the left carrying the bucket through the gate of the truck before placing the material in the truck body.

The basic operation for through the gate loading is as follows:

• The excavator raises the load and positions it next at about 45o from the cut line

(52)

2.3.7 Drive By Loading

Trucks are positioned parallel to the bench face, preferably with the operator’s cabin on the excavator side. It is the responsibility of the

excavator operator to ensure that the truck is positioned so that the

counter weight clears the truck when the excavator is swinging.

The excavator swings from the dig zone to the left carrying the bucket through the trucks gate or over the side before placing the material in the truck body.

The basic operation for through drive by loading is as follows:

• The truck operator drives into position along the bench with the truck about 2.5 metres from the crest of the face

• The e xcavator sounds the horn when the truck is in the correct position

• The excavator raises the load and swings it over the trucks side

(53)

2.3.8 Loading Trucks Off the Same Level

The excavator is positioned at floor level. Tracks can be facing either directly into the heap or at an angle across the face depending on the width of the bench.

Trucks are positioned at an angle to the to the bench face (if conditions

allow).

The excavator swings from the dig zone to left and right carrying the bucket through the gate before placing the material in the truck body.

WARNING

Although truck loading can be carried out from either side, to prevent the excavator counter weight striking a truck, o nly one truck at a time should be positioned

The basic operation for loading trucks off the same level is as follows:

• The excavator raises the load and positions it to the left or right of the digger as close to the face as possible. Excavator operator must ensure that the truck is not in the path of the excavators counter weight when slewing

(54)

EX25/36 2.5 ACT ON OR REPORT MONITORING SYSTEMS AND ALARMS
