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 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.

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 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.

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

The excavator consists of a main engine and a working device... The main engine provides power and basic movements (walking and turning), and the working device completes different operating movements... The main engine includes a walking device, a rotating mechanism, a hydraulic system, a pneumatic system, an electrical system and a power plant.1. The excavator device is the support part of the whole machine, which bears the total weight and the reaction force of the working device, while realizing the excavator with a short distance.

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.

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 working scenarios of a mini excavator can always be changed, but we have different precautions for different working scenarios.First of all, we have a small hydraulic excavator specialized in tunnel work. As this mini excavator is more suitable for tunnels, due to its overall structure is simple, and relatively can be layered tunneling situation, the safety performance of this mini excavator is also very high.Therefore, our mini excavator can be applied to the tunnel work raft, but it should be noted that the whole device of this mini excavator is like.
