The present invention relates to a lifting system (1) for lifting wooden construction elements e.g. cross laminated timber (CLT) elements, comprising a rod (3) defining a longitudinal axis, a first end section and a second end section, a lifting element (9) connected to the rod, the lifting element comprising a lift section (10) arranged to receive a hook, a rope, a wire or similar lifting equipment, and a number of dowels (7), the dowels defining a first dowel section and second dowel section, the first and second dowel section being connected via a common section, wherein the rod comprises a number of rod holes arranged to receive the dowels, and wherein the lifting element is adapted to be detachably connected to the rod.
Lifting system (1) for lifting wooden construction elements e.g. cross laminated timber (CLT) elements, comprising:
Lifting system (1) according to any of the preceding claims, wherein the hole in the lifting element comprises a thread matching a thread of the rod.
Lifting system (1) according to any of the preceding claims wherein the lifting system further comprises a nut to keep the lifting element fixated in relation to the rod.
Lifting system (1) according to any of the preceding claims wherein one or more of the dowels comprises locking means for preventing the dowel to slide out of the rod hole.
Lifting system (1) according to any of the preceding claims wherein the rod holes in the first end section of the rod are turned 90° in relation the rod holes in the second end section of the rod.
Lifting system (1) according to any of the preceding claims wherein one or more rod holes are oblong.
Lifting system (1) according to any of the preceding claims wherein the diameter of one or more of the dowels changes over the length of the dowel.
Lifting system (1) according to any of the preceding claims wherein the rod is tubular.
Lifting system (1) according to any of the preceding claims wherein the lifting system further comprises a compression plate, the compression plate being detachably arranged between the lifting element and the part to be lifted.
Lifting system (1) according to any of the preceding claims wherein the lifting system comprises a spacer arranged between fastening means and the lifting element.
Lifting system (1) according to any of the preceding claims wherein the lift section of the lifting element is arranged at a distance from the rod in a plane substantially parallel with the longitudinal axis of the rod.
Lifting system (1) according to any of the preceding claims wherein the lift section is an eye and/or a projecting pin arranged to facilitate a secure connection to a hook, a rope, a wire or similar lifting equipment.
