What Gosan does

Gosan (legal name GOSAN, S.A.) is a privately held Spanish industrial manufacturer founded in 1971 in Ortuella, Bizkaia, that designs and produces custom-made mechanical components for lifting and transport machinery. The company serves industrial customers across seven vertical segments — oil & gas, ports & shipyards, offshore & marine, general industry, mining, construction, and mobile cranes (crawler, lattice, truck and off-road). Its product portfolio is organized around four core lines: sheaves (mechanically welded pulleys in models A through E plus Pear, Solid and Nylon variants), hooks & blocks (hook blocks, suspensions, laminated hooks, motorized hook blocks, snatch blocks, sheave blocks, swivels, brackets and fairleads), couplings (AGBS and AGT10/AGH10, AGT11/AGH11, AGT12/AGH12 series, with brake drum and brake disc options), and wheels made of induction-hardened 42 CrMo4 alloy steel.

The company's underlying technology centers on mechanically welded sheave construction, a method it pioneered in 1971 and that yields sheaves approximately 40% lighter than conventional alternatives with longer service life. Gosan operates a quote-based, build-to-spec production model in which 100% of design is per customer specification, with the firm manufacturing in excess of 35,000 sheaves annually and earning an unusually comprehensive certification stack for an SME: ISO 9001:2015, API Spec Q1, API 8C monogram authority, ISO 3834/2 welding certification, and type approvals from ABS, DNV, Lloyd's Register, Bureau Veritas, CCS and RINA. With a 51–100 employee base and roughly 95% of output exported, Gosan reaches global markets via direct sales through its Spanish headquarters plus regional offices in Indonesia (Gosan Asia) and Florida (Gosan USA), serving customers in over 70 countries across all five continents.

Revenue model

1. Mechanical Component Sales: Gosan generates revenue through the manufacture and sale of custom mechanical components for lifting and transport machinery, including sheaves, hooks & blocks, couplings, and wheels. Products are custom-manufactured according to customer specifications, suggesting project-based or per-order revenue rather than standardized product sales.

Core offering

Gosan designs and manufactures custom mechanical components for lifting and transport machinery, with its core offering centered on mechanically welded sheaves (pulleys) engineered 100% to customer specification. The portfolio also includes hook blocks and related lifting assemblies, mechanical couplings (AGBS and AGT/AGH series with optional brake drum or brake disc), and hardened alloy-steel wheels for cranes and conveyors. Each product is built to order for industrial buyers in oil & gas, ports and shipyards, offshore and marine, mining, construction, and mobile crane applications.

Product overview

Gosan is a European manufacturer of custom-made mechanical components for lifting and transport machinery. The product portfolio centers on four core product lines: Sheaves (mechanically welded pulleys available in models A through E, plus Pear, Solid, and Nylon variants), Hooks & Blocks (including hook blocks, suspensions, laminated hooks, motorized hook blocks, snatch blocks, sheave blocks, swivels, brackets, and fairleads), Couplings (AGBS, AGT10/AGH10, AGT11/AGH11, and AGT12/AGH12 series with brake drum and brake disc options), and Wheels (hardened alloy steel wheels for cranes and conveyors). The company specializes in 100% custom design according to customer specifications with design flexibility and low dimensional limitations.

• SpanSet: European manufacturer of lifting slings, lashing, and rigging equipment. Comparable to Gosan in serving European industrial customers with engineered lifting solutions, though focused on textile and webbing products rather than metallic sheaves and couplings.

Direct peers

• Thiele: German family-owned manufacturer of chains, lifting components, and accessories for cranes and material-handling equipment. Closely comparable to Gosan in size, ownership profile, and focus on custom-engineered lifting components for industrial and offshore customers.
• Gunnebo Industries: European manufacturer of lifting chains, blocks, hooks, and rigging equipment. Directly comparable to Gosan's hook and block range and shares a similar European industrial heritage and export orientation toward offshore, construction, and mining customers.
• The Crosby Group: Specialist manufacturer of rigging, lifting, and material-handling hardware including sheaves, blocks, and hooks. Directly comparable to Gosan as a focused component supplier to crane, marine, and offshore lifting customers, though with a larger North American footprint.
• Bridon-Bekaert: Global supplier of steel wire rope and synthetic rope for cranes, offshore, and mining applications. Highly comparable to Gosan as a B2B component manufacturer selling into overlapping lifting and offshore end-markets, with similar reliance on classification-society approvals.
