Used 13 ton mini excavator

Types of mini excavators

A mini excavator is a compact machine designed for small-scale excavation projects. They usually have a digging arm and a rotating house and are easy to maneuver in tight spaces. There are many types of excavators based on configuration, mobility, power source, and attachments.

• Based on configuration: Mini excavators consist of short tail and zero tail types. A short tail excavator has its rear body slightly over the tracks, which makes it move smoothly in a confined space. On the other hand, a zero tail excavator has its body within its footprint. This type is perfect for projects constrained within tight perimeters.
• Based on mobility: Mini excavators can be divided into wheeled and tracked excavators. The tracked mini excavator has track pads similar to tank treads. This design offers enhanced stability and traction, especially on uneven or loose terrain. Tracked mini excavators excel in outdoor construction and landscaping projects. On the other hand, wheeled excavators have wheels that provide sufficient speed and maneuverability, especially on paved surfaces.
• Based on power source: Diesel-powered excavators are more prevalent in the construction industry. They are ideal for large-scale excavation projects. On the other hand, electric mini excavators are gaining traction in the market. This is because they are more environmentally friendly and operate more quietly than their diesel counterparts.
• Based on attachments: A mini excavator can accept numerous attachments, such as buckets for digging and transferring materials, hydraulic hammers and shears for breaking concrete and hilly rock, augers for drilling holes, and trenchers for digging trenches. Many mini excavators come ready for use with a standard digging bucket.

Specification and maintenance of used 13 ton mini excavators

Mini excavators are articulated and made up of the following parts:

• Body: The whole equipment is called the body. The body consists of the driver’s cabin (or open-air cabin), over which the outer body is formed. In a closed body, the outer part is used for safety, while in an open part, the outer glass portion serves as the upper outer part.
• Tracks: The bottom part of the excavator causes it to move around or swivel while working.
• Arm: The arm extends and swings while working to lift or lower items.
• Bucket: The bucket digs the earth and carries out tasks like gripping or loading.
• The thumb: Some buckets have a thumb attachment to them, which helps them grab materials more easily.

The following are some of the key specifications of any used 13-ton mini excavator:

• Operation weight: The operation weight typically ranges around 13000 kg, including the weight of the body, engine, driver’s cabin, attachment, and counterweights.
• Overall Dimensions: The overall mini excavator's dimensions usually range around 5 600 mm in length, 2,200 mm in width, and 2 650 mm in height.
• Dipper stick Length: The dipper stick length usually ranges from 3 meters to 3.4 meters. It can extend and retract to push or pull the bucket.
• Engine Power: The engine power typically ranges from 70 km/h to 75 km/h. An excavator's motor is what makes it go. Excavators rely on diesel motors for their power because diesel engines are typically more robust and consume less fuel than diesel motors.
• Bucket Digging Force: The bucket digging force usually ranges between 90 - 100 kN. It indicates the maximum force that the excavator bucket can exert while digging.

Maintenance

Following are some maintenance tips for a used 13-ton mini excavator:

• Check fluid levels daily, and add to the fuel, oil, and coolant; used excavators also need constant fueling.
• Always check for part wear and tear, especially the tracks. Mini excavators have to traverse difficult terrain, so to ensure they move smoothly, check their tear and wear and replace them with tracks of equal size and thickness.
• Maintain hydraulic components by cleaning the hydraulic oil and replacing filters regularly. The excavator's constant movement and rotation depend on the hydraulics and hydraulic oil quality, which helps maintain smooth movement.
• -Inspect the bucket and attachments for damage or loose parts. If the bucket, counter, or other tiny attachments are damaged, they can affect the mini excavator's functioning, which might hamper tasks that require precision, such as digging at certain levels or trenches. Common tiny excavator attachments include augers, which are used to make holes or trenches in the ground, and bevelers, which are used to dig trenches under water. Lowering the water level and digging at precise levels under the water are two tasks commonly done to lay down pipelines. Other examples of attachments that may be used for demolition include breaker hammers to demolish concrete, buckets to sort out rubble, and grapples to move large blocks. Regardless of the attachment, checking for damage or loose parts is crucial so that the excavator can carry out its task smoothly and efficiently.
• Examine belts and cables in different places. Operating a mini excavator involves many small parts joining to form a seamless whole, and cables and belts ensure that hydraulic and functioning links are optimal.
