Several features help maintain the hydraulic excavators and keep them functioning for a long time. The operators can take care of the excavator by taking care of its regular servicing and the selected tracks’ air pressure, water, and fuel conditions. A thorough inspection of the hydraulic hoses should be made to discover any potential losses, damages, or even leaks burned by heat.

If there are any operational abnormalities, unusual sounds, overheating of the engine, or abnormal vibrations, it is always better to stop the excavator and check. The operator needs to be well-trained to notice any of these issues to ensure that the excavator runs smoothly and any problem is noticed and caught before it becomes bigger and more challenging to handle.

The excavator should be cleaned daily so that there is no damage from debris, dirt, or dust, which, if left, can affect its productivity. The chain and track components, as well as those pivoted points of the excavator, should be lubricated as required. Any hydraulic component requires more frequent lubrication. Refueling, too, should be done when the engine is off, and any spills or overflows should be cleaned immediately to avoid damage and fires. Proper storage of the excavator when not in use at a dry and ventilated place is essential so that the tires do not get damaged.

Scenario

Due to its important role in the construction industry, the Daewoo excavator 55 has various application scenarios.

• Site Excavation and Ground Leveling:

  The Daewoo 55 excavator is capable of handling multiple tasks, like excavation and leveling. The powerful arm can easily level, dig and move earth. It is suitable for digging foundations, terracing, and creating areas for construction projects. Excavation is carried out precisely by the excavator's operator, who can skillfully control the vehicle with its well-designed control system.

• Trench Digging and Backfilling:

  The Daewoo 55 excavator can do trench digging with its bucket attachment. It is widely used to dig trenches for pipelines, cables, and drains. Its bucket size can be changed according to the trench width and depth. After laying the pipes and cables, the same excavator can do backfilling by using its bucket to fill the trench with soil.

• Loading and Unloading:

  The Daewoo 55 has a loading function. Its bucket can be filled with loose materials, like soil and gravel, or with items, like building materials, from the ground. The excavator will then transport the loaded materials to a dump truck or stockpile. Its flexibility allows it to serve as a loading/unloading machine in different environments like warehouses or ports.

• Dismantling Structures:

  With demolition attachments, the excavator can dismantle structures. For example, a hydraulic hammer or breaker can be used to demolish concrete structures, bridges, and walls. The operator controls the attachment to strike and break concrete accurately and precisely. This makes the Daewoo excavator a valuable asset for demolition projects.

How to choose Daewoo excavator 55

When it comes to choosing a Daewoo 55 excavator for sale, it is essential to focus on the key features that can impact its performance, application, and maintenance needs.

• Work Requirement: The choice can be simplified by knowing the work requirements. The type of work and soil condition can impact the choice of the excavator type. For instance, a crawler excavator will be preferred in off-road conditions over a wheeled excavator.
• Engine Power and Operating Weight: Daewoo excavators come in various operating weights and engine powers. Both of these features impact the handling capability of an excavator. Once the type of work is determined, buyers should easily identify the suitable engine power and weight from the available options.
• Attachments: Different work projects require different attachments. An excavator is commonly fitted with a bucket, but other attachments like a breaker, grapple, or auger can be explored as per the project requirement.
• Fuel Efficiency: As the excavator will be in operation for a long time, fuel consumption is an important factor to consider. A small excavator consumes less fuel as compared to larger ones. However, the excavator chosen should be of the right size to avoid operational delays that may lead to increased fuel consumption.
• Maintenance and Service: This is perhaps the most crucial point to consider when making a selection. An excavator that is not maintained regularly can suffer from frequent and annoying faults that affect operational efficiency. Proper and regular maintenance ensures the excavator is operating at peak performance. Daewoo excavators with easily available replacement parts should be preferred.
• Dealer Network: Buyers should get in touch with the Daewoo excavator dealer network. The dealers can arrange a convenient visit and provide insight into the excavator's specific features. The dealer will also be of help in case of further excavator needs down the line.
• Operating Comfort: An excavator operator faces various challenges during excavation. From maintaining focus throughout the day to safely maneuvering the excavator, operating comfort plays a key role in helping the operator. Buyers can choose excavators with ergonomic cabins and climate control systems for a better choice.

Daewoo excavator 55 FAQ

Q1: What is an excavator's good operating hour range?

A1: Excavators with fewer than 5,000 hours on the meter are considered to have low usage. Those with 5,000 to 10,000 hours are in the middle of the range. Excavators above 10,000 hours are relatively high in usage.

Q2: What are some signs that an excavator has taken a serious internal hit?

A2: A cracked or bent undercarriage could indicate severe internal damage. A well-used excavator usually has some undercarriage tracks stretched or worn, but severe damage shows a visible bend or crack. Major internal damage could also show up as a shiny swing bearing or a weakened hydraulic pump that fails to maintain consistent power.

Q3: What are some areas an operator can easily inspect daily or weekly for damage?

A3: The excavator boom, bucket, hydraulic lines, and cylinder seals can be inspected regularly for damage. Operators should look for cracks, corrosion, and unusual wear on these excavator parts.

Q4: What type of maintenance schedule should an excavator follow?

A4: Routine inspections of hydraulic components, tracked, weather-sealed cabins, and undercarriage should form part of the excavator's maintenance schedule. Oil changes and filter inspections or replacements should be done at least monthly or bi-weekly, depending on usage.
