• wherein the lifting cylinder device is in an operational connection with a lifting arrangement that is fastened with a first end to the lifting carriage, is fastened with a second end to the lifting mast, and is reversed on the lifting cylinder device,
• wherein the second end of the lifting arrangement is fastened to the bottom cross member, or
• wherein the lifting arrangement is fastened with the second end to the additional cross member,
• wherein at least one traction device that transmits a tractive force is provided to connect the additional cross member with the bottom cross member, and
