What are the sizes of excavator models?
2 Answers
Model 35 refers to a 3.5-ton class with a bucket capacity of approximately 0.11 cubic meters. Model 60 refers to a 6-ton class with a bucket capacity of around 0.3 cubic meters. Model 120 refers to a 12-ton class with a bucket capacity of about 0.5 cubic meters. Model 160 refers to a 16-ton class with a bucket capacity of roughly 0.65 cubic meters. Model 200 refers to a 20-ton class with a bucket capacity of approximately 0.8 cubic meters. Model 240 refers to a 24-ton class with a bucket capacity of around 1.2 cubic meters. Definition of Excavator: An excavator, colloquially known as a 'hook machine' in some regions and also referred to as a digger elsewhere, is a versatile piece of machinery that combines functions such as forward and backward movement, rotation, lifting, lowering, digging, hydraulic hammer breaking, and suction. It is used to excavate materials above or below the machine's surface level with its bucket and load them into transport vehicles or dump them at stockpile sites. Structure of an Excavator: Common excavator structures include: power unit, working equipment, slewing mechanism, control mechanism, transmission mechanism, traveling mechanism, and auxiliary facilities. Visually, an excavator consists of three main parts: the working equipment, the upper revolving platform, and the traveling mechanism.
The specifications of excavators cover a particularly wide range, primarily categorized by tonnage. Small models, like 3-6-ton mini excavators, are highly flexible for tasks such as repairing water pipes or landscaping in residential areas, capable of maneuvering in tight spaces. Medium-sized excavators, commonly in the 20-30-ton range, are the workhorses on construction sites for digging foundations and loading earth, with domestic models like the Sany Heavy Industry SY210 falling into this category. Larger 50-ton mining excavators can scoop several tons of ore in a single dig, boasting terrifying efficiency, though they require flatbed trucks for transport. Super-sized models, such as 80-ton hydraulic hammer excavators, can demolish reinforced concrete structures as easily as cutting tofu when tearing down old buildings. Selecting the right model depends on the project scale and terrain—smaller tonnage for confined spaces and larger machines for massive earth-moving tasks.
