Title: Plant and Equipment
1Plant 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.
2Plant 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.
3Bulldozer
- 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
4Excavator
- -used to dig large volumes of soil rock load
trucks - usually tracked
- have backhoe bucket variable sizes
- can turn 360O
5Wheeled Excavator
6Rock Saw attachment on excavator
7Many councils stipulate the use of rock saws to
minimise problems with adjacent properties.
8Mini 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.
9Front 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
10Small 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).
11variety of attachments for skid steer loaders
12Broom
13Rock Hammer
14Stump Grinder
15Loading a skid steer loader
16 Trucks
- used to remove soil/ spoil to tip or elsewhere
- -rated in either m3 or tonnes.
17Drilling rigs -used for drilling pier holes
18 Barge -Used for floating plant in to difficult
access areas on waterfront properties
19Dingo 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.
20 Dingo Attachments- Boring machine to place
tube underground
21Trencher Auger Cement mixer
22Equipment
- Equipment generally refers to handheld tools or
similar. - In the following frames are common examples of
typical residential construction equipment.
23Laser 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.
24Jackhammer
- 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.
27Submersible 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.
28Shovels/ Mattocks,etc -for hand held detailed
excavation
29Angle 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

you.
