Separate placing booms are used in conjunction with stationary or line pumps in applications where structures are complex, exceptionally high or do not have sufficient space for mobile boom pumps to work. Placed on tubular columns and crane masts, they can climb from floor to floor, enabling quick and efficient concrete placement.
Specialised Concrete Pumping, our specialist placing boom and stationery pump division, has an extensive range of separate placing booms and associated tower and pipeline equipment available to service a range of projects.
Climbing procedures
Self-climbing of the placing booms is conducted along the prepared openings in the floor plates. The steps are as follows:
(1) Climbing of the placing boom is achieved by handling the manually reversal valve. The operator stands beside the floor opening which is especially built for the placing boom to climb up and for the lower climbing frame to be located, so as to control the extension or retraction of the climbing cylinders.
(2) Turn the selector switch on the console to "Self-climbing" position to start the electromotor, and then operate the manually reversal valve to extend the cylinders upward, allowing the half circular holes in the cylinder piston heads to hit the upper-jacking shaft in the tower body. Keep the cylinders extending until the lower-jacking shaft in the lower frame gets loose, and then take it out.
(3) Handle the manually reversal valve upward to extend the cylinders for 500mm, allowing the hole in the lower frame to engage to that in the tower body, and then insert the lower-jacking shaft. In this case, retract the cylinders and the placing boom will fall down with the lower-jacking shaft supporting it. Take out the upper-jacking shaft and insert it into another hole in the tower body.
(4) Handle the manually reversal valve to extend the cylinders, allowing the half-holes in the piston heads to hit the upper-jacking shaft in the tower body. Keep the cylinders extending until the lower-jacking shaft in the lower frame gets loose, and then take it out to start the second climbing stroke. Repeat the above operations, and the placing boom will rise up along the climbing frames.
Cycling times of the cylinders needed for the placing boom to climb up a floor depend on the height of the floor. For instance, a 3m high floor needs 5 cycles.
(5) After finishing climbing, wedge the climbing frames tightly by means of iron wedges. The vertical force of the placing boom is transmitted from the lower-jacking shaft in the tower body to the lower frame, and the horizontal force is carried out by both the upper and lower climbing frames.
Turn the selector switch on the console to "Operating" position before the placing boom shifts to concrete placing.
Finally disconnect the climbing cylinder hoses from the pipeline-fitting plate on the tower platform, and place a part of them on the upper-platform and the other part on the tower platform for future use.

2.1 Boom
The placing boom takes advantage of mature manufacturing platform of boom design of truck-mounted concrete boom from famous manufacturers. On the base of accuracy data, the boom structure is optimized through finite element analysis, modal analysis, dynamics simulation analysis and endurance test on model machine. The accuracy of design and data is assured through powerful test and industrial assess means. The same-class weld manufacturing technique is adopted for the boom, the quality is excellent. The placing range can be changed by assembling or disassembling the extension boom to meet different placing working condition more neatly.
2.2 Rotary table and slewing mechanismÂ
The slewing support is a large-sized bearing which connects the boom and the column, and bears the overturning moment produced by the boom. It is a key component that directly affects the whole machine's safety. The motor redactor is from Comer in Italy. It is in a high speed rate, and long life span and reliable. The hydraulic motor can rotate the slewing table and the boom 365° through the redactor.
