Rolls Royce
- One rope drum to accommodate 30m of 25mm dia. tag line + 50m of 60mm hawser section + 100m of 116mm dia. hawser section. Drum barrel / flange dia 630 / 1500 mm, length 1400 mm. Drum cylinder and flanges to have ample strength for operation with rope as well as wire.
Drum is provided with a clutch which is normally fixed (bolted) to engaged position but in emergency case the drum can be released from the drive by opening the clutch mechanism.
- Hydraulic operated band brake with stainless steel lining, static capacity 90 ton at outer layer. Partial engagement by springs. Full brake capacity is obtained by both hydraulic pressure and springs (50% / 50%). Thus, in case of lack of whole hydraulic pressure approx. 50% brake capacity is available.
- line pull:
1st layer: 75 ton at O - 10 m/min
37 ton at O - 20
outer layer:
50 ton at O -15 m/min
25 ton at O - 30 m/min
- dynamic braking with electric drive:
1 st layer: 86 ton at O - 10m/min
outer layer: 57 ton at O - 15 m/min
