Only with the stable lower plate is the pump truck safe. The arm-frame pump truck supporting leg should be paid much attention.

Just like kung fu, if your "lower plate" is not strong enough, you can easily be pushed down. Whether Putzmeister second hand pump trucks' legs can firmly "plunge" on the ground, is the priority of the safe operation of the arm gantry pump truck.

1. Protect yourself and others from dangerous areas

When opening or closing the leg of the gantry Putzmeister stationary concrete pump, the rotation range is a dangerous area. People may be hurt in the range. When carrying out this operation, you should be careful of yourself and the people nearby.

2. To strengthen of the overlapping location is great. The supporting legs should be extended in place.

The legs of the arm pump truck all have fixed strengthening positions. Only when the legs are opened and extended in place can these strengthening positions give full play to the strength. Otherwise, the supporting legs will be in danger of breaking. Pay attention to the arrows on the legs and ears as you extend them.

3. Communicate with construction personnel in advance and don't "step on empty"

The gantry pump truck must be supported on a solid ground. If the maximum pressure of the supporting leg is greater than the allowable pressure on the ground, the supporting plate or auxiliary square shall be used to increase the supporting surface area. In addition, communicate with the person familiar with the construction site before supporting the leg, and make sure the leg is not above the sewer.

4. Keep a safe distance to prevent ground collapse

Adequate safety distance should be set aside to prevent ground collapse when support is near a pit or ramp.

5. The arm pump truck must be leveled and must not exceed 3 degrees

After the support is completed, make sure that the maximum horizontal deflection of the gantry Putzmeister truck mounted concrete pump is no more than 3 degrees. Generally speaking, the direction of the extension of the arm frame will be raised higher during the construction process, leaving a surplus for the subsidence after the extension of the arm frame. Currently, the arm mounted pump truck is usually equipped with an electronic level and alarm device. Once the arm mounted pump truck tilts too high, the alarm will sound to remind the operator. Before extending the armrest, make sure the legs are properly attached.

6. Remote control ensures the safety. Do not be too high from the ground

Upon confirmation of all the leg under the condition of reliable and efficient, make confirmation on the leg safety with the first and second boom. The specific approach is to stretch one arm frame, making the open Angle at 90 degrees. Then let two booms in one meter off the ground. Move one arm up and down in the position of four legs, check whether the corresponding arm bracket and diagonal arm bracket are safe.

7. If water enters under the leg, the arm shall be returned for safety

In case of the occurrence of rain water, oil cylinder leakage of supporting legs and factors reducing the stability of supporting legs, the arm shelf should be closed immediately. After the problem is eliminated, the supporting legs should be put up again according to the requirements.

In addition, when supporting the arm pump truck, it is better to keep the tire off the ground by 5 cm or so. Otherwise, the swing of the s swing tube of the arm pump vehicle and the shaking of the vehicle caused by the impact of pressure in the tube will damage the vehicle driving mechanism.

Safety precautions of Used Sany 46 Meters Concrete Pump

1. The supporting ground must be horizontal. Otherwise it is necessary to make a horizontal supporting surface.
2. The sany concrete pump for sale must be supported on a solid ground. If the maximum pressure of the supporting leg is greater than the allowable pressure on the ground, the supporting plate or auxiliary square shall be used to increase the supporting surface area.
3. When the Sany pump truck is supported near the pit or slope, sufficient safety spacing should be reserved.
4. When supporting, the whole machine should keep horizontal. The maximum horizontal Angle before and after the whole machine should not exceed 3 degrees.
5. When the legs are expanded or folded, the area in which they rotate is the danger zone. Individuals within the scope may be hurt.
6. When supporting, all legs must be extended to the specified position. (The supporting leg is aligned with the upper arrow on the ear, and the front supporting arm is aligned with the extension arm arrow on the front supporting leg) Otherwise there may be a danger of tilting.
7. The cantilever can be operated only when the supporting leg has been set up. The cantilever must be placed on the main support before the leg can be folded.
8. The cantilever must be closed immediately after a decrease in stability is detected. After removing disadvantageous factor, place them according to requirement afresh. The factors including rain, snow, and so on.

The glass plate is an important part of the Sany pump truck. Although its volume is small, its technical content and processing cost are very high. At present, glass plate can serve for about 30,000 cubic meters of commercial concrete pumping. In order to improve the service efficiency of the arm gantry pump truck, it is very important to take corresponding measures to improve its service life.

Working characteristics of glasses plate

The eyeglass plate is a part of the S-shaped Sany truck mounted concrete pump distribution valve, connecting to the commodity concrete conveying cylinder. Driven by the swinging oil cylinder, the moving part S pipe swings from one commodity concrete cylinder to the other commodity concrete cylinder. The cutting ring vibrates with the S-tube attached to the eyeglass plate. The quick swing of the cutting ring causes intense wear between the eyeglass plate and the pre-mixed concrete. It also bears the impact of cutting off the stones. It can be seen that the eyeglass plate mainly works at room temperature and bears the impact force, shear force and very strong friction.

The main failure modes of eyeglass plate are wear and fracture failure. The wear between the eyeglass plate and cutting ring is abrasive wear. First, the cutting ring and the hole Angle of the eyeglass plate are blunt, and a smaller circular surface wedge-shaped trace is formed. The wear gap increases with the increase of abrasive particle size. When the gap is large to a certain value, the construction will be affected by severe leakage of the slurry. With the increase of pump height, the impact shear of the eyeglass plate will increase, the wear will be more intense, and it is prone to fracture and collapse.

It can be concluded from the above analysis that the surface of the eyeglass plate should not only have high hardness and wear resistance but also have the certain toughness and high fracture resistance.
