Variable vibrator with adjustable static moment MRZV-V is suitable for piling and extracting of steel sections as sheet pile walls, H-beams and pipes in addition for the employment of alternative foundation methods e.g. Vibro Piles, Cast-in-place Piles, Gravel- and Sand Piles.

Before starting and running out the eccentric weights are adjusted against each other that no oscillations are generated. After reaching the preselected working frequency the static moment of the eccentric weights is adjusted according soil conditions. When running out the static moment is switched off first and afterwards the vibrator. Thus no oscillation points are generated when driving through the natural frequencies of the soil. The operator cannot only change between the minimum and maximum static moment by push of a button but also adjust defined intermediate positions.
