Custom built

We don't offer products, we offer solutions.

Our own manufacturing allows us to have a great capacity to adapt to international markets, local specifications and our customers’ needs. International standards: EN-14439, FEM 1001, Hong Kong Wind, etc.


All-round solutions

The most complete range of cranes. High Top, Flat Top, Low Top, Luffings and disassembly systems such as Recovery crane & Derricks. All of them are "full in house solutions".

Efficient design and durable components

Versatile cranes designed for ease of transportation and assembly, reducing shipping costs and on-site installation time.


High-quality, hard-wearing components, made to last. Like our slewing ring, acclaimed as one of the best on the market for its long working life. Our maintenance costs are minimal.
