Specifications and maintenance of Doosan 140 excavators

The Doosan 140 excavator has various specifications, which are crucial for its proper functioning.

• Operating weight: The operating weight of the Doosan 140 excavator ranges from 13,700 to 14,200 kg. This includes the weight of the excavator, attachments, fuel, and counterweights. A higher operating weight results in improved stability and digging strength, but it also decreases mobility.
• Overall length and width: The overall length of the Doosan 140 excavator is between 8.4 and 8.55 m, while the overall width is between 2.5 and 2.55 m, depending on the specific model. These dimensions affect how well the excavator can work in confined or open spaces and its ability to access different kinds of terrain.
• Digging depth and reach: The digging depth of the Doosan 140 excavator can reach up to 6.6 m, while the maximum digging/reach radius is approximately 9.7 m. These aspects allow the excavator to access deep trenches and carry out tasks like foundation digging and drainage work.
• Travel speed: The travel speed of a Doosan 140 excavator denotes how fast it can move from one location to another on the job site. This parameter is critical in determining the excavator's mobility and productivity. The Doosan 140 travel speed is approximately 5.5 km/h in high speed and 4.1 km/h in low speed.
• Engine power: The Doosan 140 excavator is powered by a diesel engine with a power output of around 92 kW. This engine power provides the driving force for the excavator's movements and hydraulic systems, enabling it to perform various digging, lifting, and hauling operations.

In addition to these specifications, regular maintenance is essential to maximize performance and lifespan. A well-planned maintenance schedule can help prevent breakdowns, reduce downtime, improve operational efficiency, and increase the resale value of the excavator.

• Daily checks: The operator should perform a visual inspection of the Doosan 140 excavator before starting the engine each day. This includes checking fluid levels (such as engine oil, coolant, hydraulic fluid, fuel), inspecting for leaks or damages, and ensuring that all controls and safety features are functional.
• Regular servicing: Following the manufacturer's recommended servicing schedule is crucial. Doosan excavators may have specific maintenance intervals for component replacements, lubrications, and adjustments based on the model and usage conditions. Keeping records of the servicing performed helps track maintenance history.
• Cleaning and lubrication: Regularly cleaning the excavator from dirt, debris, and mud buildup prevents corrosion and overheating. Proper lubrication of moving parts and pivot points reduces friction, minimizes wear and tear, and ensures smooth operations.
