Their design is a natural progression from the . Usage Excavators are used in many ways: Digging of , holes, Material handling Brush cutting with hydraulic attachments General grading/landscaping Heavy lift, e.g. lifting and placing of pipes , especially, but not only Driving , in conjunction with a ConfigurationsExcavators come in a wide variety of sizes. The smaller ones are called a mini-excavator or . One manufacturer's largest model weighs 84,980 (187,360 ) and has a maximum bucket size of 4.5 m³ (5.9 yd³). The same manufacturer's smallest mini-excavator weighs 1470 kg (3240 lb), has a maximum bucket size of 0.036 m³ (0.048 yd³) and the width of its tracks can be adjusted to 89 cm (35 inches). Another company makes a mini excavator that will fit through a doorway with tracks that can be adjusted to only 70 cm (28 inches) wide.Excavator attachmentsIn recent years, hydraulic excavator capabilities have expanded far beyond excavation tasks with . With the advent of hydraulic powered attachments such as a , a or an , the excavator is frequently used in many applications other than excavation. Many excavators feature quick-attach mounting systems for simplified attachment mounting, increasing the machine's utilization on the jobsite. Excavators are usually employed together with and . Most wheeled versions, and smaller, have a small backfill (or dozer-) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for pushing removed material back into a hole. Prior to the 1990s, all excavators had a hang over, or "conventional" counterweight that hung off the rear of the machine to provide more digging force and lifting capacity. This became a nuisance in tight turn areas - the machine could not swing the second half of its cycle due to restricted turn radius. In the early 1990s The Komatsu Engineering Company launched a new concept excavator line that did away with the "conventional" counterweight design, and so started building the world's first tight tail swing excavators (PC128.PC138,PC228,PC308). These machines are now widely used though out the world.
