Abstract (en)
[origin: WO2017174860A1] It is an aim of the invention to provide a method for determining the torque of an auger of a pile driving rig (10), by which the torque can be accurately determined. In the method according to the invention, the torque of the auger of the pile driving rig (10) is determined by measuring at least one of the following variables in the structures of the pile driving rig (10): the force effected by the torque on at least one point in the structures of the pile driving rig (10), the elongation caused by the force, the strain caused by the force, or the deformation caused by the force; as well as by calculating the torque of the auger from the measurement result thus obtained. Moreover, it is an aim of the invention to present an apparatus for implementing the method according to the invention, and a pile driving rig (10).
