A / R WINCH
DESCRIPTION
A/R winch is used with tensioner during the pipe laying project. When weather goes bad or other emergency situation happen, A/R winch can deliver pipes to seabed directly to make sure the vessel back to shipyard as soon as quickly. When vessel goes back to working place the A/R winch can also pulls pipes out of the sea and move bock to tensioner.
CHARACTERISTICS
Auto control & constant stress
STRUCTURE
A/R winch includes 6 parts: foundation, reduction gear, support device, drum, dynamometry rope guider, hydraulic control system. Hydraulic motor drive the reduction gear and deliver torque to drum to accomplish reel off and coiling back. Tension sensor and encoder are installed on rope guider to display the tension and speed of rope. There also has an extra foundation to weld the whole winch onto deck.
TECHNICAL PARAMATER
| Drum loading (KN) | Rope speed (m/min) | Rope diameter (mm) | Rope capacity (m) | Max working pressure (Mpa) | Break pressure (Mpa) | power (kw) | |
|---|---|---|---|---|---|---|---|
| 50T | 500 | Pull: 0~9 Push: 0~27 | 52 | 500 | 21 | 7 | 264 |
| 75T | 750 | Pull: 0~12 Push: 0~27 | 56 | 510 | 21 | 7 | 400 |
| 100T | 1000 | Pull: 0~12 Push: 0~27 | 60 | 600 | 21 | 8 | 760 |
CONTROL SYSTEM
Same as tensioner that deliver a electric signal from sensor to electric system and then to hydraulic system. distant control and on-site control are available. Distant control can installed on tensioner for convenience.
