About 8 tons excavator for sales

Types of 8 tons excavator for sale

The excavator consists of track shoes, the upper structure, and arm components like the bucket, dipper, bucket linkage, etc. Usually, the excavator has two driving wheels which can be in the form of tracts or tracks. The entire machinery moves on its own on these shoes. The chain tracks are used for easy movement in rugged terrains and muddy areas where normal tires cannot be used. The upper structure consists of the driver's cabin where the excavator operator sits, and the engine responsible for powering the excavator’s functions. An excavator comprises an arm that features a bucket and a swing set whose job is to dig and move the excavated material to the dump place. Swing sets are responsible for the movement of material from one side to another.

  • Wheeled excavator: Excavators with wheels are used for construction projects with limited movements and a high digging rate. They are rather unsuitable for rough terrains and muddy places, but they are compatible with a wide variety of attachments.
  • Dragline excavator: Only suitable for excavation from a great depth, this is ideal for open mining operations and large pond excavations.
  • Suction excavator: This excavator makes use of a powerful suction mechanism to gently extract materials like soil, gravel, and sediment from the ground. It is commonly used for delicate or non-destructive excavation, such as locating utility lines, making it ideal for urban digging sites, specifically for street work. It is also used for clearance of silt from ponds and dredging operations.
  • Backhoe excavator: The most popular excavator in the market, this excavator is used for much heavier construction work. Its job is to dig, move materials like sand, coal, and other sediments, and perform other tasks related to excavation operations.
  • Amphibious excavator: As the name suggests, this kind of excavator can easily move in both on-land and off-land terrains, thanks to its floating pontoon. It can be used for dredging tasks, marshland construction, mud-pit maintenance, and waterway clearance operations.
  • Hydraulic excavator: Applied by reverse engineering principles and using hydraulic fluids to power the excavation system, this excavator reigns supreme as the most popular type of excavator due to its versatility, precision, and efficiency.

Specifications and maintenance of 8 tons excavator for sale

Here are some vital specifications for 8-ton excavators for sale that affect their functionality.

  • Operating weight

    The overall weight of the excavator or digger machine when it is fully loaded is called its operating weight. The excavator's ability to manage and shift heavy loads is influenced by its operating weight. Excavators with a higher operating weight can shift larger and heavier items, which boosts their productivity in digging projects and construction.

  • Engine power

    The driving force behind the excavator's actions, such as digging, lifting, and moving earth, is the engine's power output, which is often stated in horsepower (HP) or kilowatts (KW). Higher engine power allows the excavator to undertake tougher tasks and operate more efficiently in demanding conditions.

  • Hydraulic system

    An excavator's hydraulic system is what allows it to dig, lift, and move heavy objects with great accuracy and force. This system relies on high fluid pressure to power cylinders and motors that perform movements like rotation, arm extension, and bucket operation. The excavator's versatility and precision in handling tasks are greatly influenced by its hydraulic system.

  • digging depth

    The maximum depth to which the excavator's arm and bucket can lower itself and dig is known as its digging depth. While performing foundation work, drainage installation, or trenching, this feature determines the excavator's ability to handle tasks that need it to access the earth at greater depths.

  • Bucket capacity

    Measured in cubic meters or gallons, bucket capacity refers to the maximum volume of soil, gravel, or other materials that the bucket can hold and transport in a single operation. This factor affects the excavator's efficiency in material handling and processing rates during construction or mining operations.

  • Reach

    The maximum horizontal distance from the excavator's rotation center to which its arm and bucket can extend is referred to as its reach. During excavation, loading, or trenching operations, reach is essential for determining how far the excavator can access particular areas.

  • Boom length

    The boom length indicates how far the excavator can stretch in an upward or downward direction. The ability of the excavator to access higher or lower locations and perform duties like demolition, loading, or digging is directly impacted by the boom length.

Maintenance tips

The mechanical system of heavy machinery like the 8-ton excavator needs regular maintenance to keep them in good condition. Here are some relevant maintenance tips for excavators that will make them last longer and work better.

  • Routine checks

    Users should create a schedule for daily maintenance work. This works best when they follow the excavator's operation and maintenance handbook. The schedule should include periodic oil change and inspection needs. When following the routine, check the excavator to see if there are any abnormal occurrences. Report any notice and address it immediately to prevent major faults later on.

  • Lubrication

    The moving parts of an excavator require constant lubrication. Regular lubrication will make it easy for the component to move, lowering the wear and tear. It will also reduce the heat generated through friction. Oil is important for hydraulic systems because it ensures proper functioning. For excavators to operate at their best, users should make sure that they choose the right oil and lubricants.

  • Timely repairs

    Timely repairs should be made after follow-up checks and regular servicing. When the components of the excavator are repaired on time, it limits the deterioration of the parts. It also prevents them from straining their roles, which will eventually lead to mechanical failure. Timely repairs also ensure that the excavator will continue to operate with maximum efficiency.

Scenarios of 8 tons excavators

  • Construction and Demolition:

    In large-scale construction projects, operators can utilize 8-ton excavators for tasks like foundation digging, trenching, and pile driving. The digging bucket can carry a high volume of soil, while the hydraulic arm offers precise control for complex trench shapes. In demolition projects, 8 tons excavators equipped with hydraulic breakers or pulverizers can dismantle concrete structures or buildings.

  • Landscaping:

    Landscaping professionals can apply 8 tons excavators to reconfigure land for gardens, parks, or public squares as well as to conduct earth-moving tasks such as grading, leveling, or creating mounds.
