e.) Operational controls in a sound proofed cab
f.) High gradeability

The propulsion system features independent hydrostatic drive/service braking of each track,
allowing steering by differential operation of the tramming control levers.
Engine

TheMid--Range series blasthole drill rigs use water cooled engines, with direct injection and turbo
chargers.

Electric starting and belt driven alternator battery charging is standard on all drill models.
The drills are equipped with dual system air filtration. Dry type 2--stage air cleaners, with optional
pre--cleaner, respectively provide clean air to the engine and the compressor.
The engine power / rpm is controlled by the engine speed control switch. The engine is shutdown
either by the removable key “ON/OFF” switch or the emergency stop switch.

Main Frame
The drill main frame consists of a track frame which supports the power pack assembly
(engine/compressor/hydraulic pumps), the combined engine radiator/hydraulic oil cooler, drill
tower assembly and three leveling jacks.

Drill Tower
The drill tower assembly features the hydro-- static driven rotary head and the hydraulic drill feed
systems. A standard 5 drill rod carousel can be controlled from the operators console to provide
safe and easy multi--pass drilling.
By using the angle drilling accessories, hole can be drilled at 5 degree increments from vertical up
to 30 degrees from the vertical.

Controls
All of the controls are positioned for operator convenience in the operator’s cab. Full details are
provided in section 4.

Tramming (Propelling)
Each track is provided with direction (Forward and Reverse) speed control leverswhich control the
tramming speed. This system also provides service braking by moving the respective levers
towards the ’STOP’ position.

Steering
The drill can be steered by adjusting the speed of one track relative to the other.

Braking
Service braking is effected by moving the tramming control lever towards the “STOP” position.
Because the LH and RH track systems are independently controlled, one track acts as secondary
braking for the other.

Parking brakes are incorporated into each track motor assembly and are fail--safe, hydraulically
released, spring applied. These brakes will therefore be applied in the event of loss of brake
release hydraulic pressure due to:
a.) Pressing a RED emergency stop switch
b.) Turning the main key operated “ON/OFF” switch to OFF position.
c.) Hose failure resulting in loss of charge pressure, when themain pumps will cut off the flow
to the tracks.

Operator’s Cab
The operator’s FOPS cab is designed for convenience, ease of control, comfort and safety while
providing maximum visibility to the work area. The operator’s station is sound insulated. A fully
adjustable suspension--mounted seat is standard. Remote Tramming Control is available at Cab
location.

Pengetahuan Dasar Tentang Drilling Rig

A drilling rig is a machine which creates holes in the ground. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person. They sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells.

Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth's crust.

Drilling rigs can be:

• Small and portable, such as those used in mineral exploration drilling, water wells and environmental investigations.
• Huge, capable of drilling through thousands of meters of the Earth's crust. Large "mud pumps" circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate many hundreds of miles or kilometres distant from the supply base with infrequent crew rotation or cycle

 There are many types and designs of drilling rigs, with many drilling rigs capable of switching or combining different drilling technologies as needed. Drilling rigs can be described using any of the following attributes:

By power used

• Mechanical — the rig uses torque converters, clutches, and transmissions powered by its own engines, often diesel
• Electric — the major items of machinery are driven by electric motors, usually with power generated on-site using internal combustion engines
• Hydraulic — the rig primarily uses hydraulic power
• Pneumatic — the rig is primarily powered by pressurized air
• Steam — the rig uses steam-powered engines and pumps (obsolete after middle of 20th Century)

By pipe used

• Cable — a cable is used to raise and drop the drill bit
• Conventional — uses metal or plastic drill pipe of varying types
• Coil tubing — uses a giant coil of tube and a downhole drilling motor

By height

(All rigs drill with only a single pipe. Rigs are differentiated by how many connected pipe they are able to "stand" in the derrick when needing to temporarily remove the drill pipe from the hole. Typically this is done when changing a drill bit or when "logging" the well.)

• Single — can pull only single drill pipes. The presence or absence of vertical pipe racking "fingers" varies from rig to rig.
• Double — can hold a stand of pipe in the derrick consisting of two connected drill pipes, called a "double stand".
• Triple — can hold a stand of pipe in the derrick consisting of three connected drill pipes, called a "triple stand".

By method of rotation or drilling method

• No-rotation includes direct push rigs and most service rigs
• Rotary table — rotation is achieved by turning a square or hexagonal pipe (the "Kelly") at drill floor level.
• Top drive — rotation and circulation is done at the top of the drill string, on a motor that moves in a track along the derrick.
• Sonic — uses primarily vibratory energy to advance the drill string
• Hammer — uses rotation and percussive force (see Down-the-hole drill)

By position of derrick

• Conventional — derrick is vertical
• Slant — derrick is slanted at a 45 degree angle to facilitate horizontal drilling

Perhitungan Kapasitas Tenaga Engine

Satuan tenaga yang umum digunakan dan sudah kita bahas pada posting sebelumnya, yaitu satuan HP dan PS.
Tenaga (power) = Kerja /satuan waktu
Kerja (work) = Gaya (force) x jarak (distance)

Pada komponen engine, gaya diwakili oleh beban (load), jarak diwakili dengan panjang (radius/ lengan pada dynamo meter, atau jarak titik pusat main journal terhadap titik pusat pin journal crankshaft), kemudian waktu diwakili oleh kecepatan (putaran per menit/ rpm).

Gaya dikali kecepatan pada engine dinyatakan sebagai torsi (torque), sehingga torsi dapat dinyatakan: Torsi = Gaya x Kecepatan
Maka tenaga engine bisa ditulis dengan formula: P = T x S
Dimana,
P = Power (tenaga)
T = Torque (torsi)
S = Speed (rpm)

Jika suatu poros (shaft) berputar satu kali dalam satu menit dapat dinyatakan bahwa poros tersebut berputar 360º/menit. Jika berputar 3/4 putaran dalam satu menit, maka dapat dinyatakan dengan 0,75 put/mnt. atau 270º /mnt.

Dapat dinyatakan dengan: 1 putaran = 360º = 2π radian

Apabila Speed/kecepatan 1 putaran / mnt = 2π x n/mnt............ atau dalam 1 putaran/dtk = 2π x n/60.

1 PS = 75 kgm/dtk
1 HP = 76,04 kgm/dtk

Karena kecepatan putaran engine biasa menggunakan putaran per menit (rpm), maka harus dirubah menjadi putaran per detik, sehingga menjadi:
P = T x S
P = T x 2π x n/mnt, menjadi:
P = T x 2π x n/60 ........ untuk menjadikan dalam satuan kgm/dtk.

Sehingga tenaga dalam satuan HP, didapat formula:
HP = (T x 2π x n)/(60 x 76,04)
HP = (2π : 4662,4) x T x n
HP = 0,001376 x T x n


Dalam satuan PS, didapat formula:
PS = (T x 2π x n)/(60 x 75)
PS = (2π : 4500) x T x n
PS = 0,001396 x T x n

Contoh penggunaan formula, jika diketahui dari grafik performance engine, engine tersebut mempunyai rated power sebesar 320 hp pada 2000 rpm, maka torque rated nya didapat:

HP = 0,001376 x T x n
HP rated = 0,001376 x Torque rated x n
320 = 0,001376 x T x 2000
Torque rated = 320 : ( 0,001376 x 2000)
Torque rated = 116 Kg.m
