Introduction
Caterpillar 428 II, 1991 is a versatile machine that is designed to handle a variety of jobs in construction and infrastructure projects. Its excellent features and specifications make it a popular choice for contractors who require a dependable and efficient machine to complete their work on time.
In this article, we will analyze the advantages and disadvantages of the relevant features and specifications of Caterpillar 428 II. We will also provide real-world examples that illustrate the practical applications of the advantages and disadvantages discussed.
SideShift or CenterMount
The Caterpillar 428 II is available in both SideShift and CenterMount versions. The SideShift version is designed for work in tight spaces where maneuverability is essential, while the CenterMount version is ideal for work that requires stability and power.
Advantages of SideShift:
– Increased maneuverability in tight spaces.
– Improved operational efficiency since the machine can be positioned closer to the job site.
Disadvantages of SideShift:
– Reduced stability since the machine is not centered.
– Reduced lifting capacity compared to CenterMount.
Real-world example: When excavating for a new building in a crowded urban area, the SideShift version of Caterpillar 428 II was preferred due to the tight space and the need to maneuver around existing buildings.
SAE dig depth
The SAE dig depth of 4141 mm is one of the key specifications of Caterpillar 428 II. The SAE dig depth is the maximum depth that the machine can excavate.
Advantages of SAE dig depth:
– Enables the machine to excavate deeper and therefore more suitable for larger construction projects.
– Improves efficiency by enabling excavation of large volumes of soil at once.
Disadvantages of SAE dig depth:
– Machine becomes less stable as the depth of excavation increases.
– Increased risk of soil collapse due to the deeper excavation.
Real-world example: A contractor used the Caterpillar 428 II with a SAE dig depth of 4141 mm to excavate a large trench for laying water pipelines. The deep excavation allowed for faster completion of the project, thereby reducing labor costs.
Reach @ ground level
The reach at ground level of 5520 mm is another important specification of Caterpillar 428 II. The reach refers to the maximum horizontal distance at which the machine can excavate or move material.
Advantages of Reach:
– Enables the machine to access hard-to-reach areas on a construction site.
– Improves the efficiency of the machine by reducing the need to reposition the machine.
Disadvantages of Reach:
– The further the reach, the more unstable the machine becomes.
– Risk of overturning the machine increases as the reach increases.
Real-world example: A contractor used the Caterpillar 428 II to clear a large area of debris for the construction of a new building. The machine’s reach allowed the operator to clear a large area of debris without having to move the machine frequently.
Loading height
The loading height of 3486 mm is the maximum height at which the machine can load material into a dump truck or other material transport vehicle.
Advantages of Loading height:
– Enables the machine to load larger material transport vehicles.
– Improves the efficiency of the loading process since the machine can reach higher.
Disadvantages of Loading height:
– The higher the loading height, the more unstable the machine becomes.
– Risk of material spillage or damage increases as the loading height increases.
Real-world example: A contractor used the Caterpillar 428 II to load crushed rocks into a large dump truck. The machine’s loading height allowed the operator to load the truck quickly and efficiently, reducing the time needed to complete the task.
Bucket width, min-max
The bucket width, min-max of 305-914 mm, refers to the range of bucket widths that the machine can use.
Advantages of Bucket width:
– Enables the machine to handle a variety of materials of different sizes.
– Improves the efficiency of the machine by enabling it to adapt to different job site requirements.
Disadvantages of Bucket width:
– Changing bucket widths can be time-consuming.
– The wider the bucket, the less stable the machine becomes.
Real-world example: A contractor used the Caterpillar 428 II to excavate a foundation for a new building. The machine used a narrow bucket width to excavate the sides of the foundation and a wider bucket width to excavate the center of the foundation.
Bucket breakout
The bucket breakout of 4640 kgf and dipper breakout of 3260 kgf are the forces required to break the soil when digging and excavating.
Advantages of Breakout:
– Increased efficiency by enabling the machine to break and excavate soil quickly.
– Reduces operator fatigue since less effort is required to dig and excavate.
Disadvantages of Breakout:
– Increased risk of soil collapse due to the force applied by the machine.
– Reduced stability as the force increases.
Real-world example: A contractor used the Caterpillar 428 II to dig a trench for laying power cables. The machine’s breakout force allowed the operator to dig through the hard soil and complete the project within the required timeframe.
Loader Bucket Capacity
The loader bucket capacity of 1 m3 is the maximum amount of material that the machine’s loader can carry.
Advantages of Loader Bucket Capacity:
– Improves efficiency since the machine can transport larger amounts of material in a single load.
– Reduces the number of trips needed to transport material, thereby reducing fuel consumption.
Disadvantages of Loader Bucket Capacity:
– The heavier the load, the more unstable the machine becomes.
– Increased risk of material spillage or damage as the load increases.
Real-world example: A contractor used the Caterpillar 428 II to transport gravel from one part of a construction site to another. The machine’s loader bucket capacity allowed the operator to transport a larger amount of gravel in a single load, reducing the time needed to complete the task.
Dump height
The dump height of 2643 mm is the maximum height that the machine’s loader can dump material.
Advantages of Dump Height:
– Enables the machine to dump into larger material transport vehicles.
– Improves efficiency since the machine can reach higher and dump material quickly.
Disadvantages of Dump Height:
– Increased risk of material spillage or damage as the dump height increases.
– The higher the dump height, the more unstable the machine becomes.
Real-world example: A contractor used the Caterpillar 428 II to dump gravel into a large dump truck. The machine’s dump height allowed the operator to dump the gravel at a suitable height, reducing the risk of material spillage.
Engine Make & Model
The Caterpillar 428 II is equipped with a Perkins 4.236 engine, which has a power of 52 kW@2400rpm.
Advantages of Engine:
– High power output enables the machine to handle heavy loads.
– Increased efficiency since the engine produces more power with less fuel consumption.
Disadvantages of Engine:
– The engine may be noisy, causing discomfort to workers and nearby residents.
– More power may lead to increased wear and tear on the machine’s components.
Real-world example: A contractor used the Caterpillar 428 II to clear a large area of debris for the construction of a new road. The machine’s powerful engine allowed the operator to clear the area quickly and efficiently.
Transmission type
The Caterpillar 428 II is equipped with a P’shuttle transmission, which
