Types of Concrete Pumps and Their Uses

Before the introduction of concrete pumps, cranes were the most used method of transferring concrete to various points.

The cranes would lift large buckets of wet concrete to the needed places. This was challenging as the cranes would only lift one bucket at a time, so there was a need for a machine to pump the concrete.

A concrete pump is a device or an appliance that is used to transfer fluid or watery concrete by pumping it to various areas.

The procedure is made easy because the concrete is in liquid form. Some concrete pumps can reach as far as 150 metres while others have the length of 72 meters but can be extended if the  need arises

How Do Concrete Pumps Work?

The pump has a valve system that uses the basic principle of hydraulics. The mixing trucks pour the concrete liquid into a hopper. The batch keeps turning to keep the wet concrete fresh.

The liquid concrete is then sucked by the valve system into the various pipes that direct the concrete to the final point. The pressure is maintained for a consistent flow of the wet concrete.

Types of Concrete Pump

There are different types of concrete pumps which are used in construction sites and they include;

Type 1: Boom Concrete Pumps

This type of pump is designed with hydraulic levers which accurately place the liquid concrete in areas that are difficult to pour. 

They offer more flexibility and mess-free pours as compared to other types of pumps.

Type 2: Truck Mounted Concrete Pumps

This is where the pump is mounted to the chassis of a vehicle. The truck will act as a delivery service and deliver the liquid concrete in an accessible area or construction site. Once the job is done the truck leaves the premises.

Type 3: Ground Line Hydraulic Concrete Pump

This transports concrete by the use of a hopper to the final destination. It has multiple pipes that are connected to reach every desired site of the pour.

This is made easy by the pipes which can navigate all inaccessible angles to pour concrete.

Use of Concrete Pumps

1.   Speed

Concrete pump as the equipment pumps wet concrete faster and saves time. This makes work easier when using it to pour concrete into the desired areas.

2.   Efficient

Less water is used when using the concrete pump technique. This helps reduce the shrinking and cracking of the concrete.

3.   Exactness

Accuracy is paramount when pouring concrete. Most especially in high-rise buildings and insulated concrete walls.

Advantages of Using Concrete Pumps

Constructions do not need delays. When using concrete pumps speed is achieved and the project work becomes simple and faster.

Some sites are inaccessible and concrete pumps have made them easily accessible. This means you can pour concrete mix at any site and angle without difficulties and spillage.

Manpower is reduced which saves you money on construction cost

A concrete pump is more convenient as compared to old methods of mix and pour.

There is a quality concrete placement and with zero material wastage

Weather is also a factor during construction. When using concrete pumps, concrete placing is not affected by weather conditions.

Up to You

Concrete pumps are highly used in concrete slab projects because they are quick and do a clean job. Large and small concrete is pushed through the connected pipes from point A to point B with no spillage.

Concrete pumps can be used in all weather conditions. Safety precautions are taken to ensure the project gets the best pour.

The use of a concrete pump is advantageous to any construction site as it is the only efficient and cost-effective machine when it comes to concrete placement.

How to properly position your concrete pump

Tips For Positioning The Boom And Stabilizing The Truck

The safe positioning of the truck is one of the major concerns when it comes to pumped concrete pour operation. Safety should always come first in such situations.
An incorrectly positioned pump can cause severe or lethal injuries, turning a common pumping job into a nightmare. The pumping team should only use the equipment after they’ve made sure all safety conditions are met and the pump truck and the boom are perfectly stabilized.

Positioning The Boom

As operators can’t rely on their eyes for precision positioning of far away objects, they should use specific technology for this operation.
– They should use a remote control to measure again the distance between the boom and the wires. The best measurement is done perpendicular to the boom, between the power wires and the placing area.
– A spotter using either a walkie-talkie or hand signals must be used to provide assistance to the operator of the boom, should this worker be unable to leave the pump.
– If the work needs to unfold after dark, the operator should position and extend the boom during daylight. After dark, a spotlight or a powerful flashlight should be used to check the distance between the boom and the power lines.

Things to check before unfolding a pump truck boom on a new site:

– Power Lines

Many elements of a truck boom are very good conductors of electricity. Moreover, the high water content in concrete makes it a great electricity conductor, should the pump come in contact with power wires. This is why electrocution is the primary cause of work related death among concrete pump operators. This is also why all concrete workers should wear rubber boots that provide protection against the high voltage carried by common residential power lines. Proper equipment is mandatory on such job sites, as it helps preventing accidents.

Half of all accidents occur when the boom is unfolded, folded or removed from site. This is why OSHA recommends to have a full time spotter to supervise these operations and warn the team about any possibility of hitting a power wire.

– Excavations

Pumping concrete near an excavation requires that for every foot of depth, the pump should be placed at least one foot away from the edge. In case of a slope, the pump may not need to have such a big setback. However, in case of a vertical drop-off, you have to observe this minimum distance.
When you need to pump concrete into an excavation, you need to be aware that most boom pumps have a much smaller downward reach. It is possible for a pump that’s able to reach up to 100 feet in height to have only 50 feet or even less this reach downward.

– Other Obstacles And Limitations

Your job site may also be obstructed by other buildings, scaffolding or cranes, to give you only a few examples of things you need to pay attention to. You should make sure you pick the proper boom length for your project. A too short one may encounter problems with various obstructions, even though it could pour the concrete correctly. This is why it isn’t enough to choose a boom that can extend as much as you need for the concrete pouring job itself, but you need to take into consideration all obstacles that may interfere with the boom.

Concrete Pump Truck Stabilization

Many pump trucks use wood and aluminum pads, as well as layers of cribbing in order to spread out the load. This mans you need to take into consideration both the bearing capacity of the soil and the one of the cribbing. As this is one of the most important steps in such projects, you should take your time and do all proper measurements and calculations required for a safe installation of your truck.

Stabilizing the concrete pump requires finding out whether the surface you’re going to mount your truck on is capable to provide adequate support. You can do this by calculating the pressure placed on the ground by each outrigger by dividing the maximum force on the leg by the area that makes contact with the ground. This area is either the area of the aluminum or wood pad, or the cribbing. If the pressure force is less than the load bearing capacity of the ground, you know that surface is safe for mounting your pump truck on.

If you need to learn a little bit more about concrete strength, what it means, why it is important and how it is determined, read below.

Understanding Concrete Strength

The first step of this process is to understand exactly what people mean when they discuss concrete strength. This is important because concrete consists of many different mixtures that break down into strength ratings that refer to calculations done by compression testing machines. These ratings tend to vary depending on whether this is residential concrete or the most sophisticated commercial structures. The strength ratings typically range anywhere between 2500 and more than 10,000.

The Importance Of Concrete Strength

It is critical that you pay close attention to concrete strength. By running compressive strength tests, you will make sure that each piece of concrete installed lives up to the requirements set forth when you planned to construct the project. This way, you will also be able to pass inspections and get the proper permits and licenses that you need for the building to be open to the public. Concrete strength is particularly important when dealing with foundations, because they set the tone for the longevity of the entire building. Always pay close attention to these ratings when you are handling any sort of construction project

How To Test Concrete Strength

The best thing you can do in order to test the strength of concrete is to bring in a professional who specializes in these sort of compressive strength tests. They will use both the standard method and machinery in order to give you the highest quality ratings that are accurate and all encompassing. There are numerous design engineers who can help you out with this, so make sure to shop around and began reaching out to these professionals when you would like to test the strength of your concrete. This is critical, no matter what sort of construction project you’re working on.

Different Types Of Concrete Pumps On The Market

Concrete pumps have been in existence for the past 50 years. They play an important part in most of the construction sites that need to transport concrete to heights. The liquid cement is transferred to the building site by pumping it with the use of a pump. If a construction site needs to transport large quantities of concrete at a greater height, there is no better way to do it than using a pump. This article provides information on the different types of concrete pumps on the market.
There are three major types of pumps used in the construction industry. The truck mounted, or boom pump, stationary or trailer line pump, and the specialized usage pump are these types. The boom pump has a remote controlled robotic arm attached to a truck. This robotic arm is also known as a boom. It is used to place the concrete at the right spot at the construction site. These trucks are usually used in large construction projects due to their capacity to hold a higher volume of concrete in order to complete the task in less time. The robotic arm helps save substantial labor.
The stationary pump is mounted on a trailer. A steel or rubber hose is attached to the machine. The hose is manually attached, and it could be extended depending on the height of the construction project. This equipment pumps concrete at a much lower rate compared to a boom truck. That’s why these trucks are used for small projects that require concrete such as swimming pools, concrete slabs in small homes, and sidewalks.
The specialized usage pump is designed for projects such as tunnels and mines. They could be rail-mounted or skid-mounted. These machines are not commonly used due to the high costs and special mechanisms involved in operating them.

You should decide to use the right equipment depending on your construction project. This equipment comes with numerous advantages to your construction site. They can place concrete at a faster rate and save valuable manpower hours in the process. On the other hand, such equipment can access places that are difficult to access with manual labor. Concrete placing is not affected by harsh weather conditions when you use such a pump. Reliability and the assurance of high-quality work are some of the other benefits offered by these tools.
The aforementioned read offers information on the different types of concrete pumps on the market.
