About Us at Dehoop Dam
Allied in association with Rotec Industries from Chicago Illinois began their involvement with DWAF in 2007 in the project planning stage of Dehoop Dam.
Rotec supplies and manufactures high speed conveyor belt systems capable of placing any kind of concrete and was the Ideal choice of placing equipment for the massive Dehoop wall.
A long line conveyor system was used to transport the R.C.C from the batch plant direct to the area where the concrete was required. The use of aluminum conveyor sections which are relatively light to handle and the characteristics of being able to flex on the radius of the dam wall are unique to this product.
Amongst other products used are two Rotec Creter Cranes, a specially engineered hydraulic rough terrain Grove Crane supporting a three section telescoping conveyor with a 61 M horizontal reach and 30 degree vertical climb and a 360 degree swing. It is designed for clean, accurate placement of concrete without segregation.
Concrete was fed either from the Mainline Conveyor system or on the case of the outlet works a feeder conveyor positioned to feed the telescope conveyor from almost any angle making it possible for ready mix trucks to approach and discharge material into the feeder conveyors, truck hopper from the most convenient approach.
The conveyors used at Dehoop Dam were 60cm wide belts with a patented scraper system delivering concrete, either R.C.C or conventional on a 24 hour basis. Designed for heavy duty applications where fast, accurate and dependable placement is required.
Allied was contracted to maintain and operate the concrete placing equipment on site at Dehoop Dam. In 2008 we built and erected a workshop complete with specialized equipment and people to sustain the Rotec equipment under the arduous conditions of the Eastern province of south Africa.
Allied provided technical support and engineering design services to the level of professional Engineers through its association with Rigonda General Engineering.
