There is no definitive answer to this question. The first problem is that the number of bones in a body changes. A fetus has about 300 bones, but by the time of birth, many of them have fused together. The average adult human has 206 bones. Also, what constitutes a joint is problematic.
Pallet Racking - Narrow Aisle. Narrow Aisle pallet racking is the space-saving option if floor space is limited: maximum storage capacity, fast accessability to every pallet and quick order-picking straight from the racking. The main advantage of narrow-aisle pallet racking is the combination of fast order-picking and the best possible use of space.
This can mean that an aisle can be as small as 1500mm when handling a conventional pallet. Originally the term very narrow aisle was used to distinguish this type of racking from narrow aisle which was originally the term given to reach truck applications. The racking in itself is the same basic components as that used in adjustable pallet racking. It is the same combination of frames and beams.
