Expert FAQ: Double Drum Hydraulic Winch Technology

1. What materials are commonly used for double drum hydraulic winch drums?

High-tensile marine-grade cast steel (Q355B, Q460) and corrosion-resistant 316L or duplex stainless steel are most common, meeting ISO 15513 and ASTM standards. Choice depends on load and marine exposure level.

2. What is the typical load capacity of a marine double drum hydraulic winch?

Common sizes range from 10 kN to 300 kN per drum, with custom builds up to 500 kN+ for heavy offshore and anchor handling. Selection depends on the application’s peak dynamic load and safety margin.

3. Which testing and inspection standards are applied?

Every unit is hydro-mechanically tested as per ISO 16841 (marine winch testing), with additional pull, fatigue, and overloading tests per DNV, ABS, and/or client-nominated standards. NDT and visual weld inspections per ISO 3834 are mandatory.

4. How is hydraulic leakage prevented in harsh marine environments?

Sealing surfaces undergo CNC-finish, using premium Parker or NOK seals, with double-lip design and positive pressure maintenance. Epoxy coating and anodized surfaces ensure marine resistance and easy clean-downs.

5. Can the winch be integrated with digital/remote control and safety interlocks?

Yes—modern systems support PLC integration, wireless remotes, CANopen, and fail-safe interlocks. Full compliance with IEC 60204-1 and mandatory emergency stop/reset provisions are standard.

6. What installation prerequisites must be met?

Mounting surfaces must be flat/level, anchor bolts sized to winch and foundation loads. Hydraulic supply must deliver design pressure/flow with clean, filtered oil (ISO 4406 Cleanliness). Proper cable sheave alignment critical for drum life.

7. What after-sales support and training options exist?

Comprehensive support: operator and maintenance training (English/Chinese), remote troubleshooting, spare parts express, and full OEM/ODM documentation. 24/7 hotline, and on-site global commissioning available.
