Claim Text:
1. Well drilling tubulars bin system, comprising a well drilling tubulars bin and control device, the well drilling tubulars bin comprising a frame structure and an elevator mechanism for holding and lifting multiple layers of well drilling tubulars, wherein the frame structure comprises a bottom frame, a left side frame fixed to the bottom frame, and a right side frame fixed to the bottom frame, the left side frame and the right side frame being of the same height, wherein the elevator mechanism comprises a liftable support structure, a left hydraulic cylinder, and a right hydraulic cylinder, wherein the liftable support structure defines a support plane for supporting the layers of well drilling tubulars, which support structure is liftable from a lower position wherein the support plane is below half the height of the side frames to an upper position wherein the support plane is at a height at least equal to a top part of one of the side frames, and wherein the control device is adapted to actuate the left and right hydraulic cylinder such that the liftable support structure is raised and lowered in a level manner, and for actuating the left and right hydraulic cylinder such that the liftable support structure obtains a tilt angle with respect to a horizontal plane towards one of the left and the right side frame, wherein the elevator mechanism further comprises a first left lift arm and a first right lift arm, said lift arms being rotatable in a vertical plane, preferably in a plane adjacent the inside of the respective left and right side frame, wherein the left hydraulic cylinder is connected to the first left lift arm for rotating the first left lift arm, and the right hydraulic cylinder is connected to the first right lift arm for rotating the first right lift arm, and wherein the first left lift arm at a first end is rotatably connected to the liftable support structure with a first left support structure pivot, and at a second end opposite from the first end is rotatably connected to the frame structure with a first left frame structure pivot, and the first right lift arm at a first end is rotatably connected to the liftable support structure with a first right support structure pivot, and at a second end opposite from the first end is rotatably connected to the frame structure with a first right frame structure pivot, such that actuation of the hydraulic cylinders causes rotation of the first left lift arm and the first right lift arm in order to lift, lower, or tilt the liftable support structure.
