Hoist Rope Attachments
RBD designs & supplies complete sets of suspension equipment for all applications of single rope drum hoisting and friction hoists of single and multi-rope systems.

Some of the component attachments are listed below:
Compactness, simplicity of attachment, dependability and safety are features of the wedge type rope cappel for service with all types of stranded and locked coil hoist ropes. It is recognised as more efficient than other forms of attachment because it exerts its grip upon the rope itself in its entirety and not on a mass of disunited wires. No bending stresses are set up, as the rope is maintained in its true vertical plane.
The action of the interlocking wedges affords a holding power greater than the strength of the rope. It has withstood full speed collision between conveyances, and overwinds without sign of failure. Cappels of this type are used in all types of hoisting systems. When fitted in multi rope friction hoists their compact design permits close rope centres.
This attachment has been part of our product range for over twenty years and the design has been checked by tests to destruction at the United Kingdom National Testing Authority. It can be fitted to both locked coil and stranded hoist rope, but because of the relatively small diameter of the thimble wedge is more suitable for stranded hoist ropes.
The rope passes around a wedge shaped thimble which operates within two rigid side plates and the rope is gripped in fixed grooves fitted between the sideplates. To reduce bending stresses to a minimum the load carrying rope is held vertically and when a load acts upon the attachment the thimble is forced into the casing without slip of the rope.
Adjustments to rope lengths caused by rope stretch are easily carried without the need to dismantle the cappel. A long section of the hoisting rope can be seen at all times thus facilitating inspection.
