HEIGHT SAFETY DAVIT WITH FAIL-SAFE MECHANISM
A davit (10) for arresting the fall of a person working at heights or for material handling where lifting of overloaded material is prevented, has a mast (12), a fuse holder (14) at the top of mast, a fuse head (16) connected to the fuse holder and having sacrificial fuses (18) arranged in series thereon, a jib arm (20) connected to the fuse head, and a primary fall arrestor system (22) having an arresting load limit and mounted to a side of the mast if the davit is to be used for arresting the fall of a person (25) working at heights, and/or a primary lifting-overload prevention system having a working load limit and safety factors if the davit is to be used for material handling where lifting of overloaded material (78) is to be prevented. When excessive forces are being absorbed either by the primary fall arrestor system or by the primary lifting-overload prevention system, the fuse head rotates downwardly relative to the fuse holder, and causes the breaking of one or progressively more of the sacrificial fuses until enough fuses have been broken to absorb the excessive forces.
