2 ton mini hydraulic crawler excavator-manufacture,factory,supplier from China

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.

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 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.

1. Ensure smooth discharge of hot air(1) Do not open the radiator compartment partition or period as the heat transfer process of the vortex assembly at random. It is not always easy to do so because of the influence of high temperature air removal.(2) A number of exhaust ports in each cabin are well known, so insist that the protections and exhaust port pumps at the bottom of the engine will prevent objects from appearing and placing or blocking exhaust heat. Is. Reducing the intake star will increase the enginetemperatures in the cabin and increase intake air temperatures.

Small mini excavator bypass valve failure today to analyze the small excavator central bypass valve failure.1. Boom lift, bucket low-speed digging and unloading, the central bypass valve is stuck in the open position, the oil output of the main pump to return to the hydraulic oil tank, the boom rise and bucket work circuit is not accessible, remove the central bypass line shaft for cleaning.2.

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.

What to pay attention to when using a mini excavator? Let's take a look.1. When used in the field, the brakes need to be properly adjusted. If the road is low and uneven, release the accelerator pedal forward, brake for speed, and then slide the inertia slowly into the air. 2. When going through muddy sections, use rough propulsion to prevent tires from slipping due to excessive speed and avoid moving or stopping along the way. 3. If there is an obstacle ahead, we will avoid it. If this is unavoidable, you need to slow down at low speeds.

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.

The hydraulic system where the output flow of the main pump is a fixed value is a quantitative hydraulic system; On the contrary, the flow of the main pump can be changed by adjusting the system is called a variable system. In the quantitative system, each actuator works according to the fixed flow provided by the oil pump without overflow, and the power of the oil pump is determined according to the fixed flow and the maximum working pressure.
