This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN ) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
Back belts are popular among workers across a number of industries—airline baggage handlers, warehouse workers, piano movers, grocery clerks, etc.—specifically to prevent lifting injuries. [2] The theory underlying the use of back belts is that the belts reduce forces on the spine, stiffen the spine, or increase intra-abdominal pressure. [1]
The medium size individual equipment belt (NSN 8465-00-001-6488) is for soldiers with waists measuring under 30 inches (76 cm) and size large (NSN 8465-00-001-6487) is for those with waists measuring 30 inches (76 cm) or over. The length of the belt is adjusted at each end by means of adjusting clamps which slide along the belt when opened. [3]
This leads to a mechanical advantage: the force needed to lift a load is only a fraction of the load's weight. At the same time, the distance the load is lifted is smaller than the length of chain pulled by the same factor. This factor (the mechanical advantage MA) depends on the relative difference of the radii r and R of the connected pulleys:
The M-1956 pistol belt had size adjustment hardware at both ends and a "ball type" buckle connector. The M-1956 pistol belt was manufactured of olive drab cotton webbing [ 3 ] to United States military specification MIL-B-40158 and was produced in two sizes: Medium, for waists under 30-inches (FSN 8465-577-4925), and Large, for waists over 30 ...
