Is it normal for the boom of a five ton XCMG truck crane to deviate?

This has a certain safe range value, if it is within the specified range, there is no problem at all, it will deviate, but if it exceeds the value, it is abnormal.

5 tons of XCMG truck crane boom deviation, this is abnormal, if he deviates, it means that his B has some situation, or there may be a reason for loose screws.

In this case, it is still a relatively normal situation. Because if you have such a large weight, this kind of situation will happen, and it is very normal to deviate.

If the real XCMG deviates with the crane boom, this is also normal, as long as it is not too much of a fish drift.

Wudun XCMG runs with the crane boom, is it normal? I think it must be a normal phenomenon like this, and they will have a little deviation.

Gude XCMG truck crane boom deviation, this must be normal, because its weight is still very large, so this must have some slight deviation.

The arm of the truck crane must be abnormal, and it must be because of the usual use or something that causes the stool to be deformed, so this situation will occur.

I think it's not normal for the mink to deviate from the big arm, and he shouldn't have gone off the rails under normal circumstances.

If this kind of large crane deviates, it is not normal, and it is actually very dangerous.

Is it normal to be next to the boom of the five-ton bicycle crane? In fact, this principle is abnormal, and the safety performance is not safe.

That's definitely not normal, you can find a professional to help you fix it.

I'm actually normal here, because we know that if it's a little cheaper, it's not special.

This five-ton Dabao crane, if it hangs low and deviates, it is actually a very small problem, you can see if you can call the official **** for inquiries?

Drum stool XCMG truck boom. Oh my God, I must pay attention to safety, safety is the most important thing!

Tons of XCMG truck-mounted cranes, if this boom deviates, it is not normal.

5 tons of his XCMG his car with the big b his deviation, I don't think it's normal, let's all adjust it later.

It is normal for the boom of the five-ton XCMG truck crane to run too large, but this is very dangerous, so pay attention to it must be tied tightly.

tons of truck-mounted cranes.

Walking is the main thing that the boom rotates left and rightIt is caused by the gap between the slewing motor gear and the turntable gear, the longer the crane is used, the larger the clearance, so the crane will be equipped with a fixed bolt to prevent the boom from rotating too much.

The truck-mounted crane is composed of three parts: chassis, crane and cargo box, which can be lifted and transported, and one vehicle is multi-purpose and multi-functional.

The truck-mounted crane needs to consider the chassis, crane, cargo box three elements, and should consider the use of the environment, the empty working environment can choose the straight arm truck-mounted crane, the narrow working environment can choose the knuckle arm truck-mounted crane.

One. Truck crane introduction:

Truck-mounted crane, also known as truck-mounted crane transporter.

It is a kind of vehicle that realizes the lifting and turning of goods through hydraulic telescopic, widely used in construction, coal mines, warehouses, docks and other narrow places, composed of chassis, cargo boxes, cranes, etc., chassis of truck-mounted cranes, cranes as an important part of truck-mounted cranes, directly affecting the transportation and working performance of vehicles, due to the particularity of truck-mounted cranes, determines the functional diversity of truck-mounted cranes.

Two. Truck crane selection:

1..The chassis girder of the truck-mounted crane has a close relationship with the crane, before choosing the required crane tonnage, select the appropriate chassis, the larger the tonnage, the heavier the required chassis weight, the thicker the girder, the large tonnage crane with a small chassis, the girder is prone to fracture and rollover, and the small tonnage crane is equipped with a large chassis, and the lifting capacity of the crane cannot be fully utilized.

2.The size and tonnage of the chassis and crane can be selected according to the actual use needs.

3.According to the actual road conditions and operating environment, the corresponding engine can be selected, and in general, there are many mountain roads and powerful engines are required.

4.The cab can be equipped with air conditioning, more comfortable driving, navigation and ABS can be installed as needed, which is convenient and safe to travel.

5.The crane can choose a straight arm or a knuckle arm crane, the working radius of the straight arm crane is large, suitable for an open working environment, the knuckle boom crane has high work efficiency, it is suitable for installing all kinds of auxiliary equipment, and is widely used in warehouses, factories, docks and other places with small working space; The installation position can be selected in the middle and rear, the middle type is installed behind the cab, the selection of lifting position is convenient, generally speaking, the tonnage of the straight arm truck crane is relatively small, the choice of the middle type is more, the rear type is installed behind the cargo box, and the large folding arm truck crane generally chooses the rear type.

The gap between the slewing motor gear and the turntable gear is too large, or the hydraulic lock failure of the slewing motor leads to pressure relief, whether the truck crane is good or bad, the bolt must be plugged in in the form to prevent the occurrence of accidents.

Hello dear wheel: what is the reason for the slow lifting of the boom of XCMG crane: check the empty oil pump and pipeline and hydraulic oil, the viscosity of the oil increases, it will move slowly, check the drive of the hydraulic oil pump, the slow movement of the boom may be caused by the failure of the oil pump.

Yes, the lifting mechanism should be operated at the same time when the boom is telescopic to maintain the safety distance of the hook, and special attention should be paid to the fact that when the boom is extended, the hook will be pulled close to the head of the boom to cause over-rolling, and the lifting of the hook should be observed at any time during the operation. If the stroke of the front arm is longer than that of the rear arm of the synchronous telescopic boom, it is an unsafe state and should be corrected, and if it cannot be corrected, it should be stopped for inspection.

When the boom is retracted with load, the provisions of the load quality of the original manufacturer's instruction manual should be observed. If it is not a special working condition, it is not recommended to carry a telescopic boom, and this operation should be avoided as much as possible in practical use, especially when it is heavy. Load telescopic will shorten the service life of the boom telescopic mechanism.

Answer: When the crane boom lifts an object, the boom cannot be retracted. Whether it is a large crane or a small crane, customers and friends must comply.

Judging from the general safety regulations for truck crane operation.

The truck crane is not allowed to telescopic when lifting.

Because the loaded telescopic boom may cause the boom bone thickness cable or rope to break.

Causing a major personal or equipment accident.

I think XCMG truck cranes should also abide by this operating principle.

According to the safety regulations and instructions, it is not allowed to carry the telescopic rod, and in actual work, the telescopic rod can be hung with a few hundred pounds.

Summary. 1) When the diameter of the main and driven wheels on both sides is not equal (caused by uneven manufacturing and wear) when the cart is running, at the same speed, the strokes on both sides are not equal, resulting in gnawing of the rail.

2) The installation position of the wheel is incorrect, which is also easy to cause gnawing of the rail. The main ones are as follows:

a The four wheels are not installed at the corners of the rectangle. The center of the same side is not in a straight line, and the wheels are deviated, which will cause both the main and passive wheels to gnaw the rails.

b. The position deviation of the wheel in the horizontal plane causes two kinds of rail gnawing phenomenon.

It is mainly used to adjust the height error, and at the same time adjust the gauge deviation. Adopt the backing plate method to adjust, select ordinary steel plate, its thickness is selected according to the measured height error of the track, the backing plate requires the surface to be smooth, no concave and convex, the width of the overall size shall not exceed 20mm of the track pressing plate, the track should be filled below, there shall be no suspension phenomenon, the pressing plate with bolts is fixed on the beam below, this method is economical, reliable, good effect, simple and easy.

The rear wheel of XCMG 80-ton crane is misaligned.

First of all, check the wheel skin to see if there are cracks, tread peeling, depression, etc. Early wear caused the wheels to crush the tread or the grinder to change to a flat surface. If the thickness of the rim is worn by 5%, the tread is worn, and there are no pitting spots on the tread, the wheel meets the use standard.

Summary. The slow action is due to the lack of power, check the hydraulic oil and hydraulic motor, the viscosity of the hydraulic oil will increase after a long period of use, and you need to change the oil.

Crane users need high-quality wire ropes, which should be wire ropes with long service life and highly stable and reliable quality. At present, the first time in the field of wire rope in the world to take prevention and control measures for fretting fatigue is the phosphate coated wire rope produced by patented technology, which is the most advanced technology in the field of wire rope in the world. Fatigue life is 3-4 times that of the same structure smooth wire rope (under comparable conditions in the laboratory), it can be verified by fatigue test, if you have a fatigue testing machine to do your own comparative test, such test results are the most credible, the service life of the wire rope is proportional to the fatigue life, the fatigue life is long and the service life is extended in proportion, according to the current wire rope market, the manganese phosphating coated wire rope is higher than the smooth wire rope, and the service life extension is much higher than the growth rate, so, The average daily use cost of phosphate coated wire rope is only 30-45% of that of smooth wire rope, which is lower in cost and more cost-effective. FYI.

What is the reason for the slow lifting of the arm of the XCMG crane?

Your question has been received, it will take a little time to type, please wait a while, please don't end the consultation, you can also provide more effective information, so that I can answer for you more coarsely and dry.

The slow action is due to the lack of power, check the hydraulic oil and hydraulic motor, the viscosity of the hydraulic oil will increase after a long period of use, and you need to change the oil. Crane users need high-quality wire ropes, which should be wire ropes with long service life and highly stable and reliable quality. At present, the world's wire rope field for the first time to take prevention and control measures for fretting fatigue is the patented technology of the production of phosphate coated wire rope, is the world's most advanced technology in the field of wire rope, rope wire after manganese phosphating or zinc-manganese treatment, the surface wear resistance and corrosion resistance of the steel wire are comprehensively improved, not easy to wear and not easy to corrode, so that the fatigue life of the wire rope is increased by the large ridge rounding amplitude, Fatigue life is 3-4 times that of the same structure smooth wire rope (under comparable conditions in the laboratory), it can be punched and verified by fatigue test, if you have a fatigue testing machine to do your own comparative test, such test results are the most credible, the service life of the wire rope is proportional to the fatigue life, the fatigue life is long and the service life is extended in proportion, according to the current wire rope market, the manganese phosphate coated wire rope is higher than the smooth wire rope, and the service life extension is much higher than the growth rate, so, The average daily use cost of phosphate coated wire rope is only 30-45% of that of smooth wire rope, which is lower in cost and more cost-effective.
