Reliance Rope Suspension
ROPE SUSPENSION-NU GLANDS
UNDERFRAME/OVER FRAME GLAND TYPE NU
The NU gland is used for suspending guide or rubbing ropes in mine shafts, the base being supported on girders in the headframe or tower. It is also used for rope anchorage and the suspension of ropes during installation or maintenance.
The gland cases are manufactured from 1.5% manganese steel to B.S. 2772, Part 2, 1989, 150 M19. The two bolt clamps and interlocking wedges in mild steel to B.S 970, Part 1, 1972 Grade 070M20 and the shackles and pins of high tensile steel to B.S. 3032:1958.
All glands are proof load tested to twice
the safe working load.
ROPE SUSPENSION-SS GLANDS & WEDGES
SPHERICALLY SEATED SUSPENSION GLANDS – WEDGES
This gland has been developed from the “NU” type and has several features which make it particularly suited for the suspension of guide and rubbing ropes. The spherical seating enables the rope to be turned periodically to present fresh surfaces to the guide rope shoes and provides compensation adjustments for any uneven settlement of the headframe making vertical alignment of the rope in the gland easier.
All glands are proof load tested to twice the safe working load.
Wedge type rope clamps are used for the lif ting and maneuvering of wire ropes of every description and for their anchoring, suspension or tensioning. Embodying the wedge principle, no white metalling is necessary. They are readily assembled, their split construction enables them to be fitted on the rope at any given point. The types of glands available for differing duties together with dimension and other basic data relating to each type of gland are given in the data tables.
Each gland is of the same basic construction and adaptable for a number of uses. The two-bolt clamps which are fitted to the rope above the interlock wedges act as a “safety block” and will come into operation to assist the wedge action if and when necessary.
The glands are suitable for ropes of all types and constructions and a wide range of sizes are
Assembly instruction booklets relating to all glands are available on request.
