Crawler 25ton engineering excavator-manufacture,factory,supplier from China

The original excavator is manual, from the invention to the present has been more than 130 years, during which it has experienced the gradual development process from steam driven bucket rotary excavator to electric drive and internal combustion engine driven rotary excavator, the application of electromechanical hydraulic integration technology fully automatic hydraulic excavator. In 1951, the first fully hydraulic backhoe was introduced at the Poclain plant in France by Case, a pioneer in crawler and wheeled excavators.

With the development of economy and the progress of society, more and more small excavators have entered our lives. With the development of economy and the progress of society, more and more small excavators have entered our lives. Since the 1980s and 1990s, small excavators have played a greater advantage in the construction of municipal engineering traffic and have developed rapidly. In these projects, small and medium-sized excavators have made great contributions to saving manpower and material resources, meeting various urban operation requirements, and maximizing thei

The 2 ton mini excavator is a flexible and efficient construction equipment designed for narrow construction sites and small projects, suitable for municipal engineering, garden construction, agriculture, road maintenance and other application scenarios.

Technical parameters:- Weight of the whole machine: about 2 tons- Power system: diesel engine, power 12-15 kilo watts- Maximum digging depth: 2.5-3 meters- Maximum digging radius: 3.5-4 meters- Maximum digging height: 3.2-3.5 meters- Travel speed: 1.5-2.5 kilometers/hour- Climbing capacity: 30°.- Bucket capacity: 0.05-0.10 cubic meters- Hydraulic system pressure: 16-20Mpa- Fuel tank capacity: 30-50 liters- Track width: 200-250mmApplicable scenes:- Municipal engineering: sewer trench excavation, road repair and other operations.- Landscaping: tree transplanting, flower bed leveling, soil excava

As one of the most important engineering machinery models in the construction of small excavators, its correct selection is also more important. How to choose the right mini excavator is by the nature of the construction task, scale, technology, economy, construction works and its matching equipment and construction time requirements and many other factors to decide.In addition, it is very important to scare a few factors: good mechanical performance, reliability and durability, short payback period, improved comfort and safety is a must.

Operating weight: One of the three main parameters of the excavator refers to the total weight of the excavator with standard working equipment, driver and full fuel. The operating weight determines the level of the excavator and also determines the upper limit of the excavator's digging force.  2.

The excavator is first of all a kind of machinery, the original intention of the mechanical design is to improve work efficiency, the excavator is no exception, all machinery is the transmission of force, the excavator is different from the common mechanical equipment is that it is not the same way of transmission, he is to use hydraulic oil to transmit force.

In the excavator according to the driving mode, according to different walking mode, according to different transmission mode, according to the classification of use, the structure of the excavator and the common structure of the relevant knowledge mining.Excavator structureanalysis: excavator is composed of bucket, bucket column, rotary arm, foot or support wheel and hydraulic system. The barrel and barrel are hinged with the column, which is hinged at the end of the rotating arm.

A new or overhauled excavator must undergo a period of trial operation, often referred to as the break-in period. The purpose of this period is to prevent early wear and tear of the excavator and to prolong its service life.

The working scenarios of mini excavators can always change, but we have different precautions for different working scenarios.First, we have a small hydraulic excavator specialized in tunnel work. Since this kind of small excavator is more suitable for tunnels, because its overall structure is simple and it can relatively carry out tunnel conditions in layers, the safety performance of this small excavator is also very high.Therefore, our small excavator can be applied to the working raft of tunnels, but it should be noted that the overall device of this small excavator is like.
