A pile assembly to be vibratorily driven into soil for a foundation includes a pile shaft, a pile tip, a mounting member and a pile sleeve. The pile tip is mountable to a bottom end of the pile shaft and has at least one pair of radial tip fins, the tip fins being arranged along a length of the pile tip. The mounting member being provided on a top end of the pile shaft and/or the pile sleeve. The pile sleeve being adapted to be arranged coaxially with the pile shaft, where the pile shaft extends through the pile sleeve, such that the pile sleeve and pile shaft are axially movable with respect to each other. The pile sleeve is adapted to be coupled with the pile shaft in an installed state of the pile assembly, where the pile assembly has been driven into the soil to a predetermined depth.

The application relates to a method for assessing the load bearing capacity of an inserted pile, including: applying, by a vibrator device arranged at the inserted pile, the inserted pile with a measuring pulse string during at least one vibration time period, detecting, by at least one detection module, motion data of the inserted pile caused by the measuring pulse string during a measuring time period, determining at least one downward motion data set from the detected motion data; and evaluating the downward motion data set such that a load bearing capacity criterion is determined.

A vibratory apparatus providing increased vibration of members held for penetrating a material with the member, by holding the members directly against the vibrating unit using the jaws, thus providing a greater amount of vibration directly transferred to the members for penetrating the material therewith while losing less energy. The apparatus can hold cylindrically shaped members at three separate points of contact or gripping positions for improved, more stable and secure holding thereof. The apparatus can be used to force a variety of different types of members into and out of the material, with or without the use of adaptor attachment components.

The invention relates to a pile driver for driving piles into ground. The pile driver comprises a body, a vibrator unit, a primary first arm and a primary second arm, both being pivotable about a primary axis; and a secondary first arm and a secondary second arm, both being pivotable about a secondary axis, which is parallel with the primary axis. The pile driver comprises an actuator or actuator arrangement for pivoting the arms. A first part of the primary first arm is provided with a primary first attachment for attaching an adapter of an adapter arrangement. An adapter for use with the pile driver. An arrangement comprising the pile driver and two adapter arrangements each comprising at least an adapter.

An apparatus for attaching a caisson to a device for inserting and/or extracting the caisson. The apparatus comprises three beams. A first beam is relatively long and is normally connected to a vibratory device such that its longitudinal axis is orthogonal to the lengthwise axis of the vibratory device. The second and third beams are relatively short and are connected to the vibratory device such their longitudinal axes are parallel to the lengthwise axis of the vibratory device. Four clamp assemblies are mounted on the beams to fix the beams onto the caisson. A flange on the first beam may be widened at at least a middle portion thereof to stiffen the beam and allow the beam to be securely connected to the vibratory device. The first beam may also be used with its longitudinal axis parallel to the lengthwise axis of the vibratory device.
