Definitions

• Steelwire clamps are used to a great extent in hoisting arrangements. Acci ⁇ dents occur relative often through this usage, due to the failure of the steel ⁇ wire clamps. An often recurring cause of this failure, is due to assembling the clamp erroneously.
• Known steelwire clamps consist of two clamp halves which, by means of one or more bolt connections, are made to be forced against each other with two steelwires in between, for example around a thimble, so that the steelwires cannot slide in relation to one another.
• the clamps are provided with a steel which when the clamps are assembled will rest on a surface of the opposite clamp half. This will have the effect of preventing the clamp halves from displacing themselves in relation to each other.
• Clamps of this type are furnished with grooves in each clamp half which when mounted together make up a S shaped slot where the steelwire is placed.
• the slot is usually furnished with ridges so that this will enclose the steelwires' outer cords tightly.
• one of the clamp halves mentioned ridges will not enclose tightly around the steelwires' outer cords, but will just yield a point by point contact against the steelwire along the ridges. Assembling erroneously this rally - way, the steelwire . will be damaged and friction between the steelwirej ⁇ ggi clamp will be severely reduced. Since none of the known clamps are furni ⁇ shed with marks which show which way they shall be assembled, it is often a coincidence if they are mounted correct.
• the object of this invention is to produce an effective steelwire clamp which cannot be assembled erroneously.
• the object is achieved by furnishing the one clamp half with studs which have different distances to the centerline of the clamp half, at the same time as the other clamp half is furnished with cut outs made to accommo ⁇ date the other clamp halves' studs.
• Fig. 1 shows a known steelwire clamp which is mounted wrong, such that the strain is absorbed by the connecting bolts.
• Fig. 2 shows a steelwire clamp in accordance with the invention mounted to a steelwire around a thimble.
• Fig. 3 shows that clamp half of the same clamp which is furnished with mating surfaces for the opposite clamp halves' studs.
• Fig. 4 shows that clamp half which is furnished with studs.
• Reference number 1 on the drawing denotes a steelwire clamp which holds a steelwire 2 attached around a thimble 3.
• the steelwire clamp 1 consists of two clamp halves parts 4 and 5 which are forced against each other over the steelwire 2 by means of a bolt and nut connection 6.
• the clamp half part 4 is furnished with two pairs of studs 7 and 8 which are arranged to lay a- gainst the corresponding mating surfaces 9 and 10 in the clamp half part 5. Since the studs 7, 8 have different distances to the clamp halves 4 center ⁇ line, then the clamp half parts cannot be connected together erroneously.
