How many inches is the XCMG 75 excavator boom light?

XCMG, how many inches is the 75 excavator boom light? The XCMG 75 excavator boom light is a six-inch one. Some. Other lamps can also be replaced.

The budget is only 30w, Sany 75, XCMG 75, Liugong 75, everyone recommends an excavator.

Soon 2020 is coming, and I am going to mention a small digging before the start of construction tomorrow, my initial budget is 300,000, and I can't do more, mainly because I am still borrowing money.

My friends told me that the best of the 75 was Kobelco. The main parts of the whole car, even the oil pipe, are made in japan. The engine is Isuzu, low noise, low fuel consumption.

In fact, I also wanted to buy Kobelco 75 before Sany 75, but the strength did not allow it, it was out of budget, and Volvo 75 is now about 350,000, and now I can only consider other brands.

At present, you are optimistic about Sany 75, XCMG 75, Liugong 75, and Lingong 75? You can recommend it.

Sany 75 Sany is the most fuel-efficient, the engine is good, Isuzu's, and we sell well here, XCMG is a domestic Kubota brand, not much to evaluate.

Kobelco 75 Liugong 75 Yanmar engine, Inle hydraulic pump valve, load sensing system, large configuration space, but I heard that the engine is loud. Lingong 75 is a new machine, I heard that there is a shadow of Volvo, ** is not very high.

Ten inches ten inches ten inches ten inches ten inches ten inches ten inches,

This light is a power indicator, if it is not lit, it means that it is not powered on or not operating normally, please check the contact problem of the connecting wire, whether the power supply line is in good contact, and whether the power supply is normal.

XCMG 75 sunroof glass, if any, is damaged or old. You have to install a new one, so you can find the manual. After reading carefully.

Let's do it again, because it's a sunroof, if the glass is not installed well. It will affect rain and earthquake protection and the like. In my opinion, it should be like installing door and window glass, and then putting it on.

A layer of coagulant is more secure in a fixed position.

XCMG, the glass of the sunroof of the 75-type excavator needs to be installed by professionals, but the new car is with glass, right?

The boom of the large excavator is generally high-strength steel, if the crack appears, it will be solved and dealt with as soon as possible, and the crack will expand a little bit in the process of use, so how to weld better? It is necessary to start the repair from the following aspects.

1. Cause of cracks. Since it is cracked, then it is necessary to find the root cause of the crack, if it is a high-strength tear of the maternal defect, then it is necessary to find out whether there are factors that are not used properly, if not, it can be repaired.

2. Crack groove design. If the repair is successful, for example, it is inseparable from the groove design, and the crack treatment groove makes your next welding must be fully occlusive, and there should be no false welding and missing welding.

3. Selection of welding materials. The carbon equivalent of this high-strength steel is generally not low, and the strength is also high, and the alloy steel welding consumables can be used for welding, such as professional repair, from the perspective of repair life, choose 860MPa, and extend up to 30% of the high crack resistance Wewelding600 electrode welding.

4. Process selection.

Low-level welds are ideal when welding crack-sensitive case-hardened metals.

1) Bevel cut heavy parts to form a 90-degree V-shaped groove.

2) It must be preheated 200 before welding high-carbon steel

3) Maintain a short arc length and use a narrow weld bead to prevent overheating.

4) Allow the weld to cool before removing the slag.

If the air conditioner is running with R410A refrigerant, the low pressure is about the same; The high pressure is about the same. If the air conditioner is running with R22 refrigerant, the low pressure is about the same; The high pressure is about the same. Too low or too high pressure is the cause of the abnormal system.

There is a tube on the rotating motor, and there is a plastic cap on the top, and you can add it by unscrewing it!
