The invention relates to a tubulars storage device (1) for storing a plurality of tubulars (2a-e), said tubulars storage device comprising spaced apart fingers (3, 4) forming therebetween a slot (5), and a plurality of pivotably mounted latch members (9a-e) arranged at spaced apart locations along the slot (5). A rotary camshaft (11) is provided for pivoting the latch members (9a-e) between a closed position and an opened position. A drive (12) is provided for driving the rotary cam shaft (11) and thus pivot the latches (9a-e), one after the other, from their closed position into their opened position. In a final angular position of the cam shaft, all latch members (9a-e) are retained, preferably by opening cams, in their opened position, and are thus all effectively locked in this position, located out of the path of displacement of tubulars (2a-e), thereby allowing displacement of the tubulars along the slot (5). |
