Used concrete pump

Types of used concrete pumps

A used concrete pump is a machine used to convey liquid concrete by pumping it through a pipe. Concrete pumps are usually used during construction projects that require concrete to be poured into specific areas, such as foundations, slabs, and walls. Concrete pumps are versatile and can be used in various projects. There are two main types of concrete pumps: the boom pump and the line pump.

• Boom pumps

Boom pumps are big machines with a robotic arm that is used to pump liquid concrete at high pressure. The robotic arm is controlled by the operator of the pump. This allows for accuracy when pouring the concrete. Boom pumps can be mounted to a truck or be placed on a trailer. Concrete boom pumps are used for large construction projects. This includes construction projects that require high volumes of concrete to be poured very quickly. Boom pumps can also be used for hard-to-reach areas, such as high areas or areas with obstacles. This is because the robotic arm can be extended and maneuvered into different positions.

• Line pumps

A line concrete pump or a stationary pump is attached to a trailer or a truck and uses a series of steel or rubber hoses to pump liquid concrete. Line pumps are versatile and are used for different types of applications. They are used for residential construction projects. This includes pouring concrete in slabs, patios, and other home foundations. Line pumps are also used for commercial construction projects. They can be used to pump concrete into sidewalks and curbs. Line pumps are affordable and are great for small construction projects. They are also great for businesses that have limited access to large equipment. Line pumps are also known for their ability to pump concrete over long distances. It can be used to pump concrete over a few hundred feet.

Specification and maintenance of used concrete pumps

Specifications for a second-hand concrete pump may vary depending on the model, type, and brand. However, the following key specifications are important to consider when looking for a used concrete pump for sale.

• Boom length

The boom length determines the reach and height of a concrete pump. The most common types of concrete pumps are boom concrete pumps and line concrete pumps. Boom concrete pumps have a robotic arm, which is a boom that can extend from a few to over 200 feet. The boom length is crucial for reaching the desired pour area. For example, a used 36m concrete pump will be ideal for indoor and residential projects with limited access.

• Pump capacity

The pump capacity, also known as the output or flow rate, is the volume of concrete that a pump can deliver per unit of time. It is usually measured in cubic yards per hour (yd3/hr). Concrete pumps come in various capacities, from 20 to 180 cubic yards per hour. Selecting a suitable pump capacity ensures that the job gets done efficiently and timely.

• Engine power

The engine power of a concrete pump is the power output of the engine, which is measured in horsepower (HP). The engine power determines how well the pump can convey concrete over a specific distance and height. It also affects the performance of the pump in terms of speed and pressure. The engine power of a concrete pump can range from 50 HP to 300 HP or more.

• Hopper capacity

The hopper capacity is the volume of the hopper, which is where the concrete is poured into before it is pumped. The hopper can be attached to the back of a truck or mounted on a trailer. It serves as a holding area and helps regulate the flow of concrete into the pump system. Hopper capacities typically range from 500 to 2,000 liters. Having a large hopper capacity minimizes the number of times the truck has to load concrete into the pump.

Regular maintenance is crucial to ensure that the used concrete pump functions optimally. The following are some maintenance tips:

• Check the pump and boom daily for leaks, cracks, or signs of damage.
• Grease the moving parts of the pump and boom regularly.
• Keep the hopper and hydraulic system clean to prevent clogs and ensure smooth operation.
• Inspect and replace the pump's wear parts, such as seals, pipes, and valves, as needed.
• Drain and replace the hydraulic fluid and filters on a scheduled basis.
• Perform regular inspections and maintenance of the engine, including changing the oil and filters.

Scenarios of used concrete pumps

Used concrete pumps can be helpful for many construction projects. Here are some of the common scenarios in which they are used:

• Bridge Construction:

Used concrete pumps are commonly used in building bridges. This machinery is essential for placing concrete in precise locations and high elevations, which are necessary aspects of constructing bridge support columns, decks, and piers.
