Abstract

AN UPPER PART (30) OF A COLUMN (28) CAN BE RAISED AND LOWERED BY MEANS OF RAMS (11) WHICH ARE NORMALLY CARRIED BY A COUNTERBALANCE UNIT BUT WHICH CAN BE ATTACHED TO THE COLUMN. THE RAMS (11) ARE MOUNTED ON A CHASSIS (10) OF THE UNIT BY MEANS OF DISENGAGEABLE PIVOTAL MOUNTINGS (22, 23) AND ARE NORMALLY CARRIED IN A STORAGE POSITION. TO MOUNT THE RAMS ON THE COLUMN, THEY ARE FIRST SWUNG ABOUT THE PIVOTAL MOUNTINGS, AND ARE THEN EXTENDED TO BRING BOSSES (19) INTO EHGAGEMENT WITH GUSSETS (32) ON THE UPPER COLUMN PART (30). THEREAFTER, THE RAMS ARE RETRACTED TO LIFT THEM OUT OF THEIR PIVOTAL MOUNTINGS (22, 23) AND ARE SWUNG ABOUT THE BOSSES (19) TO BRING THEM INTO ENGAGEMENT WITH FURTHER GUSSETS (31) ON A BASE PART (29) OF THE COLUMN.
