Plant and Equipment

1
Plant and Equipment

• Selecting the right machine is important because,
  unlike most other classes of machine, what
  appears to be the slightest increase or decrease
  in physical size can greatly affect a mini
  excavators sphere of application. There are
  three key considerations transport,
  productivity and the constraints of the site.

2
Plant Equipment used in excavation

• PLANT is a machine that is either tracked or
  wheeled and used for clearing land, pushing
  soil, excavating or loading into trucks. It is
  generally something that can be ridden upon and
  driven whereas equipment generally refers to hand
  held tools or similar.

3
Bulldozer

• used to clear land of bushes topsoil
• usually tracked
• have blades, not buckets - can only push material
• blades have adjustment up down
• use laser levels to control depth of cut
• may use tynes to tear up ground

4
Excavator

• -used to dig large volumes of soil rock load
  trucks
• usually tracked
• have backhoe bucket variable sizes
• can turn 360O

Many councils stipulate the use of rock saws to
minimise problems with adjacent properties.

Mini excavators 1-3 tonne

• The main benefit of the mini excavator is its
  size. These models can squeeze through narrow
  gaps or gateways to work on sites that would
  previously have needed hand digging or where
  features would have required dismantling in order
  to gain access.
• Mini excavators are also lighter so they are
  easier to transport.
• ZTS stands for zero tail-swing. On these units
  the rear of the machine does not extend beyond
  the width of the undercarriage when slewing. This
  means ZTS models can be positioned next to walls
  for digging.
• The upper housing and digging arm of a ZTS mini
  excavator can rotate through 180 to dump the
  bucket without the driver having to look back and
  worry about hitting anything with the back end of
  the housing.
• Expandable undercarriages allow the machine to
  breathe in to negotiate narrow entrances and
  then breathe out to provide the stability
  needed to dig and lift earth. These models are
  useful if you need to straddle narrow trenches
  for pipe or cable laying.

Front End Loader

• -used to load large amounts of soil onto trucks
• -usually wheeled - drive on roads
• -may use backhoe attachment on rear to dig
  smaller volumes of soil, detailed excavation
  load trucks

10
Small wheeled loader

• -used to dig small volumes of soil rock in
  tight access areas.
• Load soil etc into trucks

• -commonly called a Bobcat (which is just one of
  the available brands of loader).

11
variety of attachments for skid steer loaders

• auger,
• backhoe,

12
Broom
13
Rock Hammer
14
Stump Grinder
15
Loading a skid steer loader
16
Trucks

• used to remove soil/ spoil to tip or elsewhere
• -rated in either m3 or tonnes.

17
Drilling rigs -used for drilling pier holes
18
Barge -Used for floating plant in to difficult
access areas on waterfront properties
19
Dingo skid steer

• Dingos are different to the larger skid steer
  loaders. Rather than being designed primarily to
  lift and load, a Dingo is designed as a hydraulic
  power plant on wheels, to run hydraulic
  attachments. The Dingos compact size means that
  it is easy to transport, can get into back yards
  and wont make a mess of the surrounding area.

22
Equipment

• Equipment generally refers to handheld tools or
  similar.
• In the following frames are common examples of
  typical residential construction equipment.

23
Laser level

• Laser sends out horizontal beam
• Receiver set on staff or machine to intercept
  beam alert operators to current level.
• Used for a variety of trades starting at
  excavation through to finishing trades.

24
Jackhammer

• Hand held rock breaking tool light/ detailed
  excavating work
• Pneumatic jackhammer (compressed air) when you
  need extra power(grunt) usually used where access
  is tight.

25
Conveyors

• Reinforced rubber belts running on rollers used
  to remove spoil from difficult access areas up/
  down long/ steep slopes.

26

• Rubbish Chutes move refuse easily where
  wheelbarrow access is not possible.

27
Submersible pumps

• to lower water table or empty holes/ excavation
  of water
• Submersible pumps are found in many applications,
  single stage pumps are used for drainage, sewage
  pumping, general industrial pumping and slurry
  pumping.

28
Shovels/ Mattocks,etc -for hand held detailed
excavation
29
Angle Grinder and other various cutting shaping
tools

• Angle grinders are one of the most dangerous
  tools in any workplace.
• Most angle grinder injuries are from metal
  particles lodging in the operator's eye.
• However the most serious injuries are from
  kick-back, where the disc is thrust back
  violently towards the operator.
• Discs can shatter or explode, sending pieces
  flying in all directions.
• Because angle grinders are designed for grinding
  and not for cutting, the use of cutting discs
  with angle grinders exposes operators to even
  greater risks.
• All adequate PPE must be used when operating this
  piece of equipment
