First: the concrete placing boom rotation fails and there is noise

The cause of this failure: non-lubricated bearing damage



Solution: Grease replacement

Second: telescopic outrigger telescopic issuance

1) When the wind speed exceeds the sixth wind, the concrete placing boom is strictly prohibited to work. When the wind speed exceeds the fourth wind, it is strictly forbidden to install and dismantle the concrete distributor.
2) The concrete placing boom machine should keep a certain distance from high-voltage lines and electrical appliances.

Precautions for the use of the concrete placing boom machine Strictly abide by the rules of use. Correct operation is the guarantee to prevent accidents and extend the service life.

The hydraulic concrete placing boom is a new product developed to expand the limitations of concrete pouring and improve the mechanization of pumping construction. It adopts a 360-degree full reversal spreading arm frame type fabric structure, and the parts are manually controlled to change the flexibility. The proper height of the tower body can be arbitrarily changed by simply pulling the rope. It can also be fixed in the elevator shaft. It is equipped with an active climbing mechanism.

The concrete delivery pump sometimes has some small faults in use, which affects safety. Through a lot of practice, Qingke Heavy Industry has discovered that in the construction process of concrete pumps and wet spraying machines, due to the influence and influence of various factors, there are a series of uncertain safety hazards. These safety hazards have an impact on the construction progress and personnel safety. And engineering cost control is a great test.

The traditional spraying support technology of underground space mainly relies on manual operation of spraying machine construction, spraying a certain thickness of concrete to achieve the supporting effect. In the traditional spraying environment, there are a large number of dust particles, noise pollution is also quite serious, and there is a danger of underground collapse, which poses a serious threat to the life and safety of operators in underground space construction.

In the working process of the fine stone concrete pump, if the use is not standardized, it is easy to cause premature damage to some parts of the equipment, which not only increases the maintenance cost of the equipment, but also seriously affects the construction progress. Then, how to improve the service life of the vulnerable parts of the fine stone pump has become a problem that we need to pay attention to.

The double nozzle wet spraying machine is a new type of pumping wet concrete spraying machine, which adopts hydraulic pumping type, which has high construction efficiency, high system reliability and stable delivery volume, ensuring fast, uniform and stable spraying concrete operation.

The double-jet hydraulic wet-jetting machine is a pumping concrete wet-jetting machine. It adopts double-nozzle spraying operation. The production capacity is 12-16 cubic meters per hour. It has the characteristics of high pumping pressure, long conveying distance, low resilience, and high construction efficiency. . Double spray hydraulic wet concrete spraying machine is widely used for wet spraying concrete machine construction operations in mines, tunnels, culverts, subways, hydropower projec

The wet shotcrete construction process is to produce finished concrete in the cement concrete mixing station according to the mix ratio. After the concrete is transported to the working surface, the concrete wet shotcrete machine is used to press it to the nozzle position, and the quick-setting agent is added to the nozzle. High-speed spraying. In the high-speed spraying process, the concrete and the accelerator are fully combined, and the concrete spray layer is formed
