A Concrete Boom Pump is a type of equipment that is attached to a truck. It is known as a trailer-mounted boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete with pinpoint accuracy. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labor saving nature of the placing boom.
Another type of concrete pump is either mounted on a truck and known as a truck-mounted concrete pump or placed on a trailer, and it is commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home concrete slabs and most ground slabs.
Laser Screeds are self-propelled four wheel drive, four wheel steer units. It has a 20′ telescoping boom with a 12′ wide placement head. The screed head itself consists of 3 parts: the plow, the auger, and the vibrator. The plow disperses the concrete evenly, the auger removes the excess material to finished grade, and the vibrator smooths the surface.The screed has an on board computer system. This system is able to determine the correct elevation height and provide commands for to the head for elevation control.
Pumping concrete through a separate placing boom had replaced crane-and-bucket methods on many high-rise construction jobs. Mounted on a pedestal, the boom supports placing line and discharge hose, eliminating the time-consuming work of moving line and hose during each pour. A trailer mounted pump at ground level pumps concrete to the pedestal location. A quick disconnect assembly allows them to be quickly detached and either flown from one location to another on the same job or back to the truck for use on a different job.
