small powers equipment
A Mover (Figure 1.1) is used to gash grass and crops
FIGURE 1.1: Mower
Mower’s functions is to gash the grass or crops in the agricultural monopoly . They have two types of movers which is side-cut and direct-cut types. The cutting appliance could function in various methods such as reel blades, rotary blades and snipping blades.
Generator (Figure 1.2) is used to supply current.
FIGURE1. 2: Generator
Generator is very functional appliance that which can provide current during the interruption of power service and stop the break when the daily activities and business working are getting on .
2. Earth Moving Plant
Bulldozer (Figure 1.3) is used to push the soil layer by layer.(Holmes.R,1995)
FIGURE1. 3: Bulldozer
Bulldozer is a useful plant at construction site.bulldozer usually used in the preliminary site work at construction site. Preparation of digging the foundation holes can use the bulldozer to strip off the surface vegetation. It also can push the soil layer by layer and heap it at the place which close to the construction site. Bulldozer only can push the soil, waste and rubble and it cannot dig and lift up the soil.
Breakers (Figure 1.4) are used to demolition of buildings ( Geeno. R,2007)
FIGURE 1.4: breakers
Breakers, generally called a sledges or scrubber rams, are earth shattering percussion gadgets used for isolating bond or shake. They can mounted on an excavator and it controlled by colleague water fueled systems. They are practically identical in limit and assignment to hand-held pneumatic drills. Breakers are regularly used as a piece of utilization, for instance, destruction of structures, isolating black-tops or avenues, breaking hardened ground, helper diminishment of affected material and trenching in shake.
The concrete mixer (Figure 1.5) is used to mix the
FIGURE 1.5: concrete mixeraggregate, cement and water to form concrete ( Holmes. R, 1995)
The concrete mixer is normally used to mix the sand, aggregate ,cement and water to form concrete. Then,it can make each of the composition on the micro and macro evenly.Also it can increase the collision between the material and particles friction, and decrease the impact of dust film. The concrete mix by concrete mixer is more better than hand mixing concrete because of collision. The small amounts of concrete can easily transport on construction site by using the concrete mixer with wheelbarrow,if the poor condition of the ground soil,planks can use as walkways.
Concrete mixing trucks (Figure 1.6) is used to transport the mixed concrete from depot.(Jalal Afsar,2012)
FIGURE 1.6: Concrete Mixing Truck
This truck used to transport the mixed concrete which from the depot or mixing plant to the construction site. The truck has a big water tank which has around 1000 litres capacity, to prevent the concrete setting while transporting the mixed concrete to the construction site. The chute of the concrete mixing truck will extends from the back of this vehicle when the truck want to place the concrete to the location which required the concrete or place the concrete into a pump and dumper.
Dumper Truck (Figure 1.7) is used to transport materials (Holmes. R 1995)
FIGURE1. 7: Dumper truck
This plant uses to transport the large amount of material needs to on or off site. The dumper truck also use to transport the loose material such as excavated dirt, sand,gravel and so on from the construction site to another place. The bodies of the dumper truck are heavily-plated and operated hydraulically. The different dumpers have a different options such as elevated tipping, side and front and also the carrying capacity.
Crane (Figure 1. 8) is used to lift and lower materials (Holmes. R, 1995)
FIGURE 1.8: cranes
Cranes is vital for carrying heavy material such as steel bar or can be lifted tasks of all kinds in construction work.Cranes is equipped with cables and pulleys,the application of cranes is based on the fundamental mechanical principles.The human construction workers is well beyonded because it can lift and lower loads.The design of cranes has been changing to satisfy the requirement of a variety of industrial needs.The cranes must be carefully used because it would be dangerous for human workers even though it is very helpful in construction work.
5. Excavation plant
Face shovel (Figure 1.9) is used to excavate the soil (Greeno. R, 2007)
FIGURE 1.9: Face Shovels
This machine can excavate any types of soil and including rock.Face shovel is feature by bucket arn hydraulic ram, bucket ,boom and front discharge bucket.Faca shovels generally is used to removal of top spoil.The machines are available to a universal power unit based machine or a hydraulic purpose designed unit.Many of the face shovels have been limited capacity between 300 and 400mm to excavate below their own track or wheel level.
Dragline (Figure 1.10) is used to control a drag bucket (Chudley. R,2007)
FIGURE 1.10: Dragline
Dragline is the heavy equipment in civil engineering projects,it is used for surface mining and construction work. Dragline is used to carry material at far distance from the machine such as carry material from storage to the construction site.Dragline is consisted large bucket,hoist rope,boom, drag rope and driving motors.There are two types of separate function ropes such as hoist rope and drag rope are attached with bucket.
Trenching machine (Figure 1.11) is used to excavating long trenches (The editors of Encyclopaedia Britannica, July 2)
FIGURE 1.11: Trenching Machine
Breakers, jointly mentioned as a hammers or hoe rams, are effective percussion instrumentality used for ending concrete or rock. they’re going to put in on associate degree excavator and it powered with the help of auxiliary hydraulic systems. they are comparable in operate and operation to hand-held gasolene drills. Breakers ar unremarkably utilised in code like demolition of buildings, ending pavements or roads, breaking frozen ground, secondary reduction of blasted cloth and trenching in rock.
Multi-purpose excavator (Figure 1.12) is used to excavate the soil (Jalal Afsar, June 2012)
FIGURE 1.12: multi-purpose excavators
These machines area unit usually in sight of the agricultural tractor with two or four wheel drive and area unit expected for the foremost half to be used in conjunction with very little uncovering works, as an example, those old by the limited to medium measured building written agreement employee. Most multi-reason excavators area unit fitted with a stacking/uncovering front pail and a back backacter basin each being victimization controlled water controlled. At the purpose once in task utilizing the backacter instrumentation the machine is raised off its axles by raise mounted pressure driven outriggers or jacks and in a very few models by setting the front will on the bottom. Most machines will be fitted with associate assortment of will widths and completely
different connections, as an example, tractor sharp edges, scarifiers, snatch cans and post gap bit borers
