Truck-mounted Boom Pump（
Concrete Pump Truck ） is used either in the jobsites where the
concrete is difficult to reach or where there is a large quantity of
concrete requirement. The
Truck-mounted Boom
Pump is suitable for jobsites such as skyscrapers or basement with limited access, which not only can save manpower, but also work time and money.
The operating principle of a
Truck-mounted Boom
Pump is not complex, which needs to pour the
concrete from the
pump truck. In the most prevalent form, a
concrete pump truck is a large, diesel-power
truck equipped with a powerful
pump, and an extendable, sectioned boom or cylinder frame.
The
concrete is transported to the
Concrete Pump Truck by a cement mixer, generally known as a
batching plant or
truck mixer. In order to prevent the
concrete from setting-up or hardening, the cement mixing vehicle needs to keep constantly rotating. Small amount of water is also required to keep the
concrete from hardening. During the
pump running, the ready-mixed
concrete will be dumped from the
truck mixer into the bay of the
truck. The boom mounting on the
pump also has an auger to constantly churn, keeping the
concrete liquid and flowable.
The extendable hose or cylinder booms on
concrete pumps are usually from 17 meters (55.77 feet) to 61 meters (200.13 feet) in length. Some booms even reach to the length of more than 80 meters. In accordance to the size of the
truck, or the general chassis, the boom can be folded into three to six sections, including the base section. Therefore, the boom length determines how far away the
truck will be placed from where the
concrete is to be
pumped.
