Viback, EXEN`s top of the line Dam concrete placement vibrator system.Over 200 units sold to the world.This is the dam concrete placement machine of autocratic operation which carries powerful hydraulic powerd vibrator in exclusive excavator.The worker who operates hand operation vibrator was not needed, laborsaving and efficient continuous operation became possible. Big power is demonstrated on placement of dam construction.

Laborsaving is realized

Conventionally, although it was placement by human power, if it use viback, powerful oil pressure vibrator demonstrates big power, and can realize laborsaving.

Powerful and perfect vibrating consolidation is realized

The φ to 3cm slump concretes for dams are big coarse aggregate (a maximum of 150mm).Therefore, 3 to 8 units of hydrauric powered vibrator is used, a powerful vibration is given, and concrete with high intensity is made.

Vibroisolation structure which suppressed the vibrating transfer for excavator

The original structure which took the vibroisoration is adopted as a vibrator attachment portion.

The hanging hook for main part is equipped

It equips 3 places, the boom part of the hydraulic excavator itself, and a counter weight part, with a hook. Conveyance with the crane into a placement block can be performed smoothly.

A run on the concrete surface is also easy

When running a placement place with a hydraulic excavator, a 600mm broad shoe is adopted. So it can run a concrete placement surface easily. Moreover, it is also possible to attach rubber pud in the shoe surface so that a concrete placement surface may not be damaged.

The tip of wear resistance

Since the concrete for dams is firmly non-fluidity unlike usual construction and concrete for engineering works, the tip of vibrator is remarkably worn out during placement. Then, a tip is adopting what heat treatment to ductile cast iron, and is excellent in wear and abrasion resistance, and its durability is also 2times-improving compared with the former. In consideration of repair etc., exchange of only a tip is also possible.
