Drum winder
|
Objective: To complete the first hybrid rope field trial involving local mining authorities in the process to verify the detection and discard in a production drum winder application specifically hybrid ropes. Outcomes:
|
Rope Details 1.3/4" diameter 6x25 round strand with a HMPE core |
Application: Ni/Cu Underground Mine The shaft is equiped with double drum winder (material) operating to 1600m |
Friction winder
|
Objective: To extend the service life by taking advantage of the load bearing core to increase operating safety factor and to verify the detection and discard in a friction winder application specifically for hybrid ropes. Outcomes:
|
Rope Details 40mm diameter 6x25 Brangle triangular strand with a HMPE Core |
Application: Main hoist rope material winder operating at 802m depth. Friction winder (4x850m) |
