Choosing the right machine is crucial for the economic and technical success of vibration work. We offer our customers individual advice to enable them to select suitable equipment, taking into account all the relevant factors – such as the building site and the geological and technical requirements.

Ambient factors
The type of vibrator that will be suitable specifically depends on the size and the weight of the foundation elements to be introduced, the introduction depth and the soil condition. In principle, the centrifugal force and the amplitude must be chosen such that the shaft friction and the toe resistance between the foundation element and the surrounding soil can be overcome.

Support when selecting equipment
The nomogram below will help you select the right equipment or the required centrifugal force – depending on the soil properties and the weight and introduction depth of the foundation elements.

Additional equipment such as rinsing lances or pre-boring rigs can be used in order to achieve considerably better results with the same dimensions or centrifugal force. The power delivered by the power pack must be sufficient to achieve the required momentum and, as a result, the required centrifugal force in difficult soil. The drive power must be 2-3 kW per 10 kN of centrifugal force.

Please feel free to contact one of our expert advisers for personal advice when selecting the equipment, based on soil conditions and foundation elements. They will use simulation software to determine the optimum machine for your project.
