Description:
The laborsaving placement machine of the autocratic operation whichdemonstrates power to dam construction.It is the dam concrete placement machine of autocratic operationwhich carries powerful oil pressure vibrator in exclusiveexcavator.The worker who operates hand operation vibrator was notneeded, laborsaving and efficient continuous operation becamepossible. Big power is demonstrated to placement of damconstruction.
Conventionally, although it was placement by human power,if it is viback, powerful oil pressure vibrator demonstrates bigpower, and can realize laborsaving.
The concretes for dams are big coarse aggregate (a maximumof 150mm) and low slump concrete (0-3cm of slumps). Therefore, oilpressure vibrator is used, a powerful vibration is given, andconcrete with high intensity is made.
Since the concrete for dams is firmly non-fliidity unlikeusual construction and concrete for engineering works, the tip ofvibrator is remarkably worn out during placement. Then, a tip isadopting what heat treatment to ductile cast iron, and is excellentin wear and abrasion resistance, and its durability is also2times-improving compared with the former. In consideration ofrepair etc., exchange of only a tip is also possible.
