Daily operation, maintenance and maintenance of truck cranes

The rotation rig is a construction machinery that is suitable for hole -forming operations in the basic engineering of the construction. It is widely used in infrastructure construction projects such as municipal construction, highway bridges, high -rise buildings and other places, and cooperate with different drillings, which are suitable for hole -forming operations of dry (short spiral), wet type (rotation) and rock formation (rock diamond). The rotary rig drilling machine is mainly suitable for the construction of soil layers such as sand, viscous soil, and powder soil. It is widely used in various foundation infrastructure such as irrigation piles, continuous walls, and basic reinforcement. The rated power of the rotor rig is generally 125-450kW, the power output torque is 120-400kn · m, the maximum hole diameter can reach 1.5-4m, and the maximum hole depth is 60-90m. Essence The rotary rotor drilling machine has the

How many machines are the five major repair techniques for the excavator hand -made engine. Have the engine faulty problems when driving the excavator? What will be dealt with when the engine is abnormal? Let me talk about the common manifestations and judgment methods of engine failure. I. Insufficient motor power of the excavator, an abnormal noise, an analysis of the failure of the exhaust pipe with black smoke: This phenomenon is due to the late ignition, the pressure of the machine combustion chamber is insufficient, and the engine power drops suddenly. As a result, a loud noise. And because the burning gas is mixed with it to produce black smoke. Solution: If you find a problem, you should contact the repair shop in time for repair. Second, when the excavator engine oil appears, a large amount of failure is analyzed

High frequency analysis of hydraulic excavators has a high frequency of failure. Nowadays, the technology of excavators has been significantly improved. With the advancement of science and technology, modern excavators basically adopt the control mode of machine, electricity, and liquid. Therefore, in the process of actual operation, if the excavator fails, we usually check the matching problems of the engine, hydraulic pump and external load. In the process of excavators, most of the problems appear on the matching of external loads. If they do not get a good match in this area, the engine speed will slow down, the operating speed is slow, or even the weakness. Below, let's take a look at the performance and exclusion method of these fault problems. Slow the engine speed. If the output power of the engine is far lower than the rated power, you should check whether the fuel filter element has occurred
