Extended hoses are required because a standard truck-mounted pump cannot spread concrete straight from the hose tip of the pump line above the fourth or fifth story. A placement boom gets around this restriction. The structural engineer or building inspector may forbid dragging a hose across a post-tensioned deck due to their concerns regarding the post-tensioning cable profiles.
A placement boom can frequently feed concrete from a central location to the entire floor, depending on the scale of the project. A crane and concrete bucket is a popular substitute, but it is sluggish and ties up the crane. Although the place and finish crew are paid a fixed rate, their inefficient functioning lengthens the cycle time between bucket loads. The crane can only bucket concrete; it cannot perform any other tasks, which hurts the general contractor and other crafts. The complete assembly departs the construction site until the next deck pour, when the boom is remounted on the pump truck at the end of the pour.
Using our putzmeister concrete boom pump and a specialized laying boom that stay on the jobsite for the life of the project is the second option. The positioning boom and pump are available for monthly rental. It is utilized to install all raised decks and vertical concrete, and it becomes a set monthly expense. Despite being significantly more expensive per cubic yard than just renting a traditional boom truck, this method uses all of the concrete, which minimizes the cost per cubic yard.
Boom-related components
There are numerous bases to which the placement boom can be fastened. When mounted on a tower crane mast, a placement boom can be placed inside or outside the building's footprint. Because of its strength and adaptability, it can be utilized in situations where extending a pump truck's outriggers with its base outside of the building footprint is not feasible due to adjacent electrical wires.
