4-cylinder diesel 12 ton excavator-manufacture,factory,supplier from China

The chemical energy of the diesel oil is converted into mechanical energy by the diesel engine, the mechanical energy is converted into hydraulic energy by the hydraulic plunger pump, and the hydraulic energy is distributed to each actuator (hydraulic cylinder, rotary motor + reducer, walking motor + reducer) through the hydraulic system, and then the hydraulic energy is converted into mechanical energy by each actuator. Realize the movement of the working device, the rotation of the rotating platform and the walking movement of the whole machine.1.

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.

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.

The working principle of excavators can be divided into two aspects, namely mechanical drive and hydraulic control. Mechanical drive is driven by the engine to drive the transmission chain, drive the mechanical arm, bucket rod and bucket to complete the excavation and loading operations; Hydraulic control is to drive the oil circuit through the hydraulic pump to control the movement mode and action of the mechanical arm and bucket, making the operation of the excavator more accurate and efficient. In terms of mechanical drive, the core component of excavator work is hydraulic engine.

A hydraulic excavator is a type of construction machinery commonly used for excavating earth, clearing silt, excavating rivers and mines, excavating buildings and infrastructure, and other earthmoving works.

The original excavator was manual, and it has been about 140 years from its invention to 2018, during which it has experienced the gradual development process from steam-driven bucket rotary excavators to electric and internal combustion engine driven rotary excavators, and fully automatic hydraulic excavators with mechatronic hydraulic integration technology. The first hydraulic excavator was successfully invented by the Poclin factory in France. Due to the application of hydraulic technology, in the 1940s, there was a hydraulic backhoe mounted on the tractor.

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.
