Information

Small excavator products are developed according to two main categories. Single bucket excavator and multi bucket excavator. Today, we mainly understand the performance characteristics of single bucket small excavator products.

In modern single bucket small excavators, large excavators are usually special excavators with only one working device (front shovel or rope shovel). Medium sized excavators are usually special-purpose or semi general-purpose excavators, which can be used as front shovel, rope shovel or hook as overweight machine. Small excavators are usually general excavators. According to the needs of the orderer, they can be equipped with the following working devices or part of them: front shovel, backhoe, planer shovel, rope shovel, scraper, grab, hook, pile driver, etc.

Most modern single bucket excavators are installed on crawler running devices, automobile running devices and walking devices. Road running devices and floating devices are rarely used.

In modern single bucket small excavators, most of the large excavators are driven by electricity, and most of the small and medium-sized excavators are driven by internal combustion engine or internal combustion engine hydraulic drive.

In modern open-pit mining, it is very economical to rely on excavators to directly dump the stripping work (without other means of transportation), which promotes the rapid development of the production of large single bucket excavators for stripping. The characteristics of this kind of excavator are: large bucket capacity (positive bucket capacity is 4 ~ 100m, rope bucket capacity is 4 ~ 25m); The size of the working device is very large; The weight is very large, corresponding to Haimi. The bucket capacity and self weight of the excavator reach 40 ~ 90 tons, which is about twice the corresponding value of small and medium-sized excavator products (30 '~ 45 tons); The running device of this small excavator product is four track or eight track or walking type; The power equipment is always driven by multiple motors of the generator motor system.

The manufacturing process of this small excavator is also very complex. For example, the bucket capacity is 20m. The excavator needs a vertical lathe with a diameter of 10 meters, a gear cutting machine with a diameter of 3 meters and a boring machine with a diameter of 5x15 meters. The maximum weight of castings and forgings is 15 tons and 8 tons respectively, and the maximum weight of assembly parts is 30 tons.

The main technical and economic indexes of modern single bucket excavator are as follows: corresponding to each meter. The productivity of bucket capacity, when directly stacking and discarding soil, is 100000 ~ 350000 meters Year or 80 ~ 200m / Hours; The hourly productivity corresponding to the weight of each ton of excavator is 2.3'x'4.5 meters / Hour (front shovel), 1.2 ~ 2.4m / Hours (walking rope shovel, large for large), If the weight of the means of transport is also taken into account, it is 0.6 "- 2.5 M. / h; the hourly productivity corresponding to the power per horsepower is: 0.6 ~ 1.4 M. Chuan, Shi (when there is no transfer by means of transport), 0.2 ~ 0.5 M '/ h (when there is transfer by means of transport); the engine power corresponding to the bucket capacity per meter is 120" ~ 140 HP; Corresponding to every 1m of excavation. The power consumption of soil is 0.4 ~ 1.2 kW · H (electric drive), and the fuel consumption is 0.06 "'-'0.15 kg (diesel drive); corresponding to Haimi.

Small excavator products are generally special, and its working device is only suitable for certain conditions.
