Key Components:
- Base frame and support structure
- Anchor chain wheel and wildcat
- Braking system and gear mechanism
- Power transmission unit
- Electrical control systems (except manual models)
- Drive units: electric motors or hydraulic power packs
Classification by Drive Mechanism:
- Manual windlasses
- Electric windlasses
- Hydraulic windlasses
- Pneumatic windlasses
Technical Specifications:
- Chain diameter range: φ12-φ120mm
- Single or double-gypsy configurations
- Rated pulling capacity and load holding capability
- Lifting speed specifications
- Power system requirements
Installation Requirements: Proper installation ensures optimal chain engagement with 117-120-degree contact angle between chain and wildcat.
