What Is Concrete Trailer Pump
Trailer concrete pump can’t move by itself. Therefore, it is also called stationary concrete pump or static concrete pump. There are two types of concrete trailer pump for sale in HAMAC, one is driven by a diesel engine and the other is driven by an electric motor. Since trailer concrete pump is equipped with wheels, Just install the pump on a simple trailer can it be easily moved on the construction site. It can also be pulled and towed on the road. Concrete trailer pump is a commonly used concrete conveying equipment for construction projects.

Working Principle of Trailer Concrete Pump
The piston of the concrete cylinder is respectively connected with the piston rod of the main oil cylinder. Under the action of hydraulic oil, the main oil cylinder reciprocates, one cylinder advances, and the other cylinder retreats. The outlet of the concrete cylinder is connected to the hopper, one end of the distribution valve is connected to the outlet, and the other end is connected to the swing arm through a spline shaft, and can swing left and right under the action of the swing cylinder.
When pumping concrete, under the action of the main cylinder, one piston advances and the other piston retreats. At the same time, under the action of the swing cylinder, the distribution valve communicates with one concrete cylinder, and the other concrete cylinder communicates with the hopper. Thus, the retreating piston sucks the concrete material in the hopper into the concrete cylinder, and the other piston continues to move forward to send the concrete material in the concrete cylinder to the distribution valve to pump out.
When the concrete piston retreats to the end of the stroke, the reversing device in the water tank is triggered to make the two main cylinders reversing. At the same time, the direction of the two swing oil cylinders is reversed, so that the distribution valve communicates with the concrete cylinder, and the other concrete cylinder communicates with the hopper. At this time, one piston retreats and the other piston advances. In this way, continuous pumping is achieved.

Choose Diesel Concrete Trailer Pump or Electric Concrete Trailer Pump
Electric trailer concrete pump relies on an external three-phase 380V voltage. The motor rotates to provide power to the main oil pump, thereby driving the operation of the entire hydraulic system.
Diesel trailer concrete pump relies on its own diesel engine to provide power to the main oil pump and drive the operation of the entire system.
Consumption costs for electric powered pumps are much lower than for diesel powered pumps. However, the construction site should have a three-phase power supply. If not, a transformer needs to be prepared, and the cost will be high.
The diesel trailer concrete pump is more convenient to use, as long as there is diesel, it can work anywhere.
The electric trailer-mounted concrete pump has low noise and little environmental pollution. Diesel trailer-mounted concrete pumps are noisy and pollute the environment.
For trailer-mounted concrete pumps of the same model, diesel-powered ones are more expensive than electric ones.
The diesel type require frequent maintenance of diesel engines, and later maintenance costs are higher than the electric type.
What Are Components of A Trailer Mounted Concrete Pump
It is mainly composed of power device, concrete pumping mechanism, concrete distribution valve, concrete mixing mechanism, hydraulic system, electric control system, lubrication system and supporting walking device.
Power device
The concrete trailer pump power unit has two kinds of engines, diesel engine and electric motor. The selection of motor power and main oil pump must match. The main oil pump adopts axial plunger type variable pump. The output flow is directly proportional to the driving speed and the displacement of the pump, and can be discharged steplessly between maximum and zero. It has the functions of constant power control, pressure cut-off and electric proportional flow regulation.
Pumping mechanism
The pumping system is a power actuator that converts hydraulic energy into mechanical energy. Its function is to push the concrete to overcome the pipeline resistance and reach the pouring site. It is mainly composed of two main cylinders, a water tank, a reversing mechanism, two concrete cylinders, two concrete cylinder pistons, a swing arm, two swing cylinders, a distribution valve, a discharge port and a hopper.

Hopper and mixing system
The volume of the hopper should be adapted to the concrete delivery volume of the pump. The upper part of the hopper is equipped with a grid screen to prevent large aggregates or sundries from entering the hopper. There are stirring blades in the hopper, which can carry out secondary mixing on the concrete mixture, and has the feeding function of pushing the concrete mixture to the concrete distribution valve.
Support and walking mechanism
It is mainly composed of underframe, axle, including road wheels, guide wheels and outriggers. The bottom frame is the basic part for the connection of various parts of the trailer pump, which is welded by profile and steel plate, and plays a supporting role for each part. The front of the bottom frame is connected with the hopper, and there is a trailer at the rear, which can transport the towed concrete pump from one construction site to another easily.
Water pump device
The water pump device is a kind of water washing device used by the gate valve to tow the pump to clean the pipeline and the pump. It is composed of water tank, water filter, water pressure gauge, oil tank, water valve four-way block, spit valve, suction valve, etc.
Cooling system
There are three cooling methods for hydraulic oil, water cooling, air cooling, water and air cooling. Different cooling methods can be selected according to regional climate differences and construction conditions.
