piles to be tested in a day or multiple cycles on a single pile at 15-minute intervals. Further description of the hydraulic catching mechanism is given by Middendorp (2000). The most recent development is the mounting of a 1 MN Statnamic device on a 360° tracked excavator which allows rapid deployment (1 hour) and increased production.
