When pouring concrete, how high can the concrete pump truck pour?

At present, among the commonly used automobile pumps, the arm length of more than 30 meters to more than 40 meters is the most, and a small number of arm lengths reach more than 50 meters to more than 70 meters.

Generally, the building is poured concrete, and the applicable height of the car pump is arm length minus 20 meters (horizontal movement and pump truck should be considered.)

The distance from the house is the arm length required), which means that the height of 20 meters is suitable for a car pump with a 40 meter arm length and the height of 40 meters is suitable for a car pump with a 60 meter arm length.

The longer the arm of the car pump, the larger the required road and the location of the pump, so there are many construction sites that cannot use a pump truck of more than 60 meters (generally a 60-meter car pump, the width of the pump and outrigger position needs to be about 14 meters).

When the floor height exceeds the applicable height of the car pump, the ground pump (fixed pump) will be used to pour concrete, and the height of the general pump can reach more than 100 meters to 200 meters.

The longest pump truck in the world is a 101-meter ultra-long boom pump truck produced in China.

Concrete pouring refers to the process of pouring concrete into the mold until plasticization, and the machinery that uses pressure to continuously transport concrete along the pipeline, which is composed of pump body and conveying pipe, and is divided into piston type, extrusion type and hydraulic diaphragm type according to the structural form.

The pump body is mounted on the chassis of the car, and then equipped with a retractable or flexibly foldable distribution rod to form a pump truck.

The concrete pump truck is transformed on the chassis of a truck.

It is installed on the chassis with motion and power transmission device, pumping and mixing device, distribution device and some other auxiliary devices, the power of the concrete pump truck transmits the power of the engine to the hydraulic pump unit or the rear axle through the power transfer case.

The hydraulic pump pushes the piston to drive the concrete pump to work. Then use the distribution rod and conveying pipe on the pump truck to convey the concrete to a certain height and distance.

Up to now, the market should be more used by Sany Group and Zoomlion, with the increasing demand and the acceleration of construction, 52m and above length of pump trucks are increasingly more useful.

The length of the pump truck is calculated based on the horizontal length of the boom on the pump truckThat is, when the boom is in a completely beaten and open horizontal state, from the center point of the first section arm and the rotating tower base to the end of the last section.

The measured length is followed by an integer one step up. (Note that this does not include the length of the rubber tail hose). If measured, it is 36 meters; In the same way, the meter is 42 meters.

Concrete pump.

Concrete pump, also known as concrete pump, is composed of a pump body and a delivery pipe. It is a kind of machinery that uses pressure to continuously transport concrete along pipelines, which is mainly used in housing construction, bridge and tunnel construction.

50 meters is indicated on the pump truck. is not 50 meters long.

meters or so.

Cement mixer (concrete mixer) is a special truck used to transport concrete for construction; Due to its appearance, it is also often referred to as a snail car. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete.

The mixing drum is always kept rotating during transportation to ensure that the concrete carried does not solidify. After transporting concrete, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space, so that the volume of the mixing drum is getting smaller and smaller.

The composition is composed of automobile chassis, mixing drum, transmission system, water supply device, full-power power take-off, front and rear brackets of the mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, the four major pieces of domestic mixer truck tank volume of 3m -8m are used, and most of the four major pieces of domestic mixer truck with a volume of more than 8m are imported components.

The mixer truck is composed of: second-class chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, human ladder and other parts. The front end of the mixing tank is connected with the reducer and is installed on the front of the frame, and the rear end is supported by two supporting rollers installed in the back of the frame through the raceway.

<> depends on how generous the mixer truck you make. If it is used in a mountain tunnel, it can be controlled to about meters, 5 cubic meters, 6 cubic meters, 7 cubic meters of mixer truck height is about meters, 10 cubic meters, 12 cubic meters, 14 cubic meters, 15 cubic meters of mixer trucks.

In the form of meters, mixer trucks of more than 15 cubic meters exceed 4 meters, and can probably do meters.

According to the moisture content of the concrete transported by the concrete mixer truck, there are three kinds of mixer trucks: wet material type, dry material type and semi-dry material type. Most of the wet material concrete mixer trucks are used in China, which can transport the concrete produced by the mixing plant (station) or the aggregate (sand, gravel), cement and water mixed according to the ratio, and in the process of transportation, the wet material is constantly slowly stirred to prevent the initial setting and segregation of concrete in the transportation process. However, the time from production to pouring of concrete generally cannot be exceeded, so as to avoid concrete solidification.

Therefore, in the case of longer distance transportation, dry and semi-dry material mixer trucks are used to transport. The dry material mixer truck can directly load the dry aggregate and cement into the mixing drum of the truck according to the proportion, and the dry material in the drum is mixed during transportation, when the vehicle is about to arrive at the construction site or add water to the construction site to complete the mixing of concrete. The aggregate and cement in the concrete transported by the semi-dry material mixer truck are also prepared according to the proportion, and contain a certain amount of water, but the water content does not meet the pouring requirements, and it is necessary to add water and stir at the construction site when the vehicle is about to reach the construction site or at the construction site.

Summary. Dear, I am a life lover who has helped more than 6000 people and am happy to answer your questions. 1. According to different models and manufacturers of concrete pump trucks, the maximum height of water delivery is not the same, and it can generally reach 50 meters.

2. The stone of the pumped concrete is mixed by different particle sizes and different ratios, that is, aggregate gradation. The sand and the stone are combined according to a certain ratio, that is, the sand rate. When mixing, a certain amount of cement, fly ash, mineral powder, water, etc. are added.

Hope mine can help you, please give a like, thank you!

Dear, I am glad to answer for you: how many meters can the concrete pump truck deliver water A: Dear Hello, the concrete pump can transport 300 meters.

The concrete pump truck is equipped with a wide and void, and the pumping height is determined according to the length of the pump truck boom, which is generally the last 2 sections of the arm for combined pumping. The concrete pump truck can be sent to about 100-120 kilometers, which is determined by the time of cement curing, because the concrete can be kept in the pump truck for 2 hours without lowering the bottom mark, so it can run about 100 kilometers in 2 hours. And outside of 2 hours, no more than 3 hours should be used with a lower mark.

But it must not exceed four hours, and if it is exceeded, it can only be reported as good as celery. Thank you for your patience. The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best!

Peace and joy!
