1. A method for cutting an elongated shell-type object being a wind turbine blade, an aero-plane hull, a vessel hull, glass fiber reinforced container, a tank, a vessel, or a pipe, the method comprises the following steps:
providing a gantry that defines a portal, the gantry including a wire grid operable in the portal, the wire grid comprises several cutter wires and the step of providing the gantry includes attaching a sled comprising a sled support to the shell-type object at a distal point relative to the gantry and a pull system having one or more cables extending between the sled and the gantry;
operating the wire grid; whilst
moving the shell-type object through the wire grid along a lateral-axis substantially perpendicular to the portal by pulling the sled towards the gantry by pulling the one or more cables as a function of the position of the distal point of the shell-type object; and
determining a strain on the wire grid to prevent breakage of the several cutter wires, wherein the step of pulling the sled and the shell-type object is performed as a function of the strain.
