Hey everyone
               I will be doing several posts throughout the next few days and answering your questions as we go. We have hundreds of pictures which will be available on our website www.kcppump.ca and on CD that will be available at the World of Concrete. You are getting the whole story here first on www.concretepumping.com. Included here are some of the most important pictures to give you an overall idea of how the placing boom works
            
The Pump
 
      This 60 meter pump was designed specifically for CC Myers Inc to be able to pump various mixtures of concrete. The majority of their work is bridge construction so we knew we had challanges to face. Bridge mixes are undoubtedly the nastiest things to pump, also Nevada DOT were coming up with new designs at the same time to meet new criteria for this very special project and environment.
 
     What we came up with was a 170 meter/hour high pressure pump kit. The pump operates on the piston side with tandem hydraulic pumps to supply adequte oil volume. We use 9" X 83" concrete cylinders and a large mouth S-tube to minimize reduction throughout the concrete supply system. At the transition door we reduce straight to 5" heavy duty. Immediatley after the reduction we installed a really nifty hydraulic diversion valve supplied by Pumpco parts. Oil for the diversion valve is supplied from the outrigger circuit.
 
     From the diversion valve, the system passes through the tower along a series of 45 and long sweep 90 degree elbows with a swivel joint at the bottom. The system is clamped to the tower and  converts back to 5" metric at the boom. Truemax Construction Equipment supplied the system and helped with the design. We strap 5" HD system and long sweep elbows to a mixer and blow out the system with air into a concrete mixer. We use a blow out cap with a pressure guage and pressure relief valve. CC Myers is using a ConForms Ruffneck 5X4 reducing hose and aircuff at the tip supplied by Protech Concrete Pumps.
 
    I don't want to get long winded so will supply information on the tower tomorrow. Just to answer some questions for now though, it does slew from the base which has counterweights on it. There are pendant lines from the base to the counterbalance arm at the back of the boom. This removes almost all the bending moment on the tower. ( It must flex some) There are counterweights on the outriggers which are fully hydraulic and operated by the KCP pump. The boom is a 4 pin detachable with quick couplers on the hydraulic system.
 
       This boom is incredibly smooth. The operator says even smoother than on the truck. OSHA inspected the system and were very satisfied with the design. They were very surprised when they had us operate at full volume, flat boom with less than 6 inches of boom bounce. We were pleasantly surprised also.
