6 ton mini excavator

Types of 6 ton mini excavators

The 6-ton mini excavator is available in various types and models to meet different working environments and needs. The following list highlights some

• Dumpers

  They are dumper trucks loaded with excavators often used in mining or construction projects. The combination offers excellent material transport and minimization of labor costs. The dumper can either be on-road or off-road, with the latter having larger tires for better traction and stability.

• Hydraulic excavator

  The machine uses hydraulic cylinders and fluid to perform various functions, such as digging and lifting. A 6-ton hydraulic mini excavator may have one or two undercarriage rollers on top of a track system. It provides stability to the machine when working on uneven or sloped grounds.

• Long-reach excavators

  A 6-ton long-reach mini excavator for sale comes with an extended arm. It is suitable for digging at a distance or depth from the machine's body. Long-reach excavators are ideal for projects like dredging trenches, digging ponds, or excavation in tight spaces.

• Wheeled excavators

  They are excavators mounted on rubber wheels for faster travel speeds across flat surfaces compared to tracked excavators. A tracked mini excavator 6 ton may be better in terms of traction and stability in off-road conditions. However, wheeled excavators are preferable for urban construction sites with better infrastructure.

• Zero tail swing excavators

  Having a counterweight that is located within its width, a zero tail swing excavator can move, swing, and operate in confined spaces without worrying about hitting obstacles behind the excavator. This makes them suitable for working in tight and congested areas.

Specification and Maintenance

Some specifications must be considered when looking into 6 ton mini excavators. They impact functionality and performance, ensuring they are well-suited for various digging and construction tasks.

  • Length: This ranges between 3.1 and 3.9 meters. The overall length impacts aisle width and trenching ability.
  • Width: It ranges betwee1 1.5 and 2.2 meters. The overall width determines the stability while working on uneven surfaces.
  • Working Height: This ranges between 3.5 to 4.2 meters. The overall height determines the ability to take in large/overhead projects like dismantling at a construction site.
• Engine Power: This ranges between 40 to 60 kilowatts (53 to 80 horsepower). The overall power determines the pushing and digging force, affecting performance and fuel efficiency.
• Digging Depth: Mini excavators have a maximum digging depth ranging from 3.5 to 5.5 meters. The depth indicates the machine's capability to excavate trenches, foundations, and other features.
• Dipper and Arm Reach: Mini excavators reach from 2.6 to 4 meters. The reach determines the ability to access areas away from the machine.
• Bucket Capacity: Mini excavator buckets have a capacity ranging from 0.1 to 0.3 cubic meters. The capacity affects the amount of material processed per hour during excavation.

Maintenance

For a 6 ton mini excavator to stay in optimal condition throughout its lifetime, periodical maintenance is crucial. Here, the most important and common maintenance tasks are detailed along with their explanation.

• Daily Inspections: The operator should check the excavator before starting to ensure it’s in excellent condition for smooth operation. During this, they should inspect the following areas:
  • The hydraulic hoses and tracks for any signs of leaks or damage
  • The fluid levels, such as coolant, hydraulic oil, diesel fuel, and engine oil
  • The buckets and attachment for any signs of wear or damage
  • The filters, including the air and hydraulic filters, for clogs
  • The bolts and pins to prevent any loose attachment components
  • The tracks and undercarriage for any build-up of mud and debris
• Regular Service: Hire a certified technician for regular and periodic services based on the excavator's operating hours. During the service, the following should all be checked and serviced:
  • The engine oil should be changed, as well as the oil filters
  • Hydraulic system inspection should be done and any cleaning or replacement required for serviced components.
  • The fuel system should be inspected, and any clogs or filters should be cleaned or replaced
  • The cooling system should be inspected for proper functioning and any cleaning required
  • The electrical systems and connections, along with the battery, should be properly inspected

6 Ton Mini Excavator FAQ

Q1. What does the ton capacity of an excavator mean?

A1. Excavators come in different sizes, and each is suited for a specific type of task. The ton capacity of a mini excavator refers to its weight and its ability to handle or swing material. Consequently, knowing the ton capacity can help a buyer know its suitability for a particular task.

Q2. How does a 6 ton mini excavator swing?

A2. The swing mechanism of a mini excavator comprises a frame attached to the undercarriage with a center pin. Its housing includes the upper structure or house that contains the operator's cabin, engine, and other key components. By rotating the house over the frame, the entire excavator can perform a 360-degree swing. When the excavator swings, the weight distribution and design of the excavator ensure stability.

Q3. How is a 6 ton mini excavator transported?

A3. A mini excavator is small and light enough for transport on a medium-sized trailer or truck. Many suppliers will recommend using a flatbed truck or a low-boy trailer for transporting the excavator. It will help if the excavator is securely bolted or strapped during the journey, put on the roads, or offloaded at the destination.

Q4. Does a 6 ton mini excavator have a hydraulic system?

A4. Yes. It is mostly the case for mini excavators. A hydraulic system powers the excavator arm and bucket to offer controlled movement and high force. The hydraulic system comprises a pump, cylinders, and valves. The engine of the mini excavator will drive the hydraulic pump to circulate hydraulic fluid under high pressure through the system.

Q5. What are some attachments for mini excavators?

A5. Excavators may come with or support other attachments. The most common include a thumb and grapple to hold objects better; a ripper to break up hard or frozen ground; a hammer to crush rock; a bucket to dig material and a trencher to dig trenches. Suppliers may offer excavators with some of these attachments.
