  • Open the slab grab Riba and put it onto the centre of the stone slab.
  • Now it has to be put into the hook of the lifting device by using the two eyes of rope. [B2 Picture 5.2]
  • The stone slab has to be dry, free of wax, oil and sand. The surface of the stone slab which is to be lifted also has to be even in the area of contact with the slab grab!
  • Now put your slab grab Riba with the lifting device in the middle of the stone slab.



Picture 5.2 – Slab grab Riba put in the middle of the slab and unlocked /
  • Release the hollow set screw [A2] of your slab grab Riba (see picture 5.2)
  • Now the slab grab Riba is unlocked
  • Take care that the pull-lift and the lifting device have a suitable carrying-capacity to carry the stone slab and the slab grab itself.
  • Lift the slab grab Riba with the lifting device until the stone slab is hanging and take care that the slab grab is not swinging while lifting it. If necessary change the position of the slab grab and put it closer to the middle of the stone. Don’t lift jerkily!

/ Attention! Danger!

Picture 5.3 – Positioning the stone slab /
  • The stone slab can also be put on. To do this only bend the stone slab to one side. Be aware that the stone slab might break by the influence of its own weight.
  • Be aware that an unfixed crane while putting on a stone slab might topple over because of the high shear forces!
Attention! Danger of hurting by breaking stone slabs! The stone slab can break while putting on by its own weight! Avoid any presence of third persons while putting the slab on.
