Kraaijeveld Winches

What Kraaijeveld Winches does

Kraaijeveld Winches is a Dutch manufacturer of winches and winch drive systems for maritime and industrial applications, operating from a single facility in Sliedrecht, Netherlands since its founding by Cornelis Kraaijeveld in 1927. The company designs and produces custom-engineered winches largely tailored to customer specifications, spanning dredging winches, waterfall/anchor-handling winches, anchor/mooring winches, towing winches, barge winches, offshore winches, and capstans, complemented by hydraulic and electric drive packages, PLC-based control systems, and the patented SafeWinch system that separates recovery and rendering torque to prevent gearbox overloading and is approved by classification societies.

The firm operates a direct-sales-led, engineering-to-order business model, building on a project basis for international customers including dredging contractors, offshore operators, commercial shipping lines, and inland barge operators. Documented shipments reach at least 12 countries across Europe, the Middle East, Asia-Pacific, and Latin America. Revenue is generated through hardware sales of new winches, spare parts (including authorized legacy support for the discontinued THR Marine, SEC Groningen, and Ten Horn brands whose intellectual property Kraaijeveld holds), and aftermarket service/repair work supported by a 350-ton test bench and 24-hour in-Europe field response capability. The marketing footprint consists primarily of the company's product website (safewinch.com).

In August 2025 the company was acquired by Dutch maritime manufacturer Straatman, integrating Kraaijeveld's winch capabilities into a broader maritime manufacturing platform while preserving the existing brand, team, specialized engineers, and service operations in Sliedrecht. Distribution is direct to enterprise customers worldwide with no channel intermediaries disclosed, and pricing is bespoke per engineered specification rather than list-based.
