WL - Walvoil Distributor Bank
Parallel monobloc proportional hydraulic distributor bank. It is characterized by strength and simplicity of operation.

MPES - Multi Power Extension System
A Fassi system that guarantees an exceptional extension/retraction speed of the telescopic booms, built up by a set of equally powerful independent rams, linked in series connection and activated by a single control. Special independent fixing system of the extension rams to guarantee high vertical lifting performances.

UHSS - Ultra High Stregth Steel
Ultra high strength steel used for the construction of the Fassi structural components, with a high elastic limit, increases structural strength and resistance of the components and at the same time reduces the weight of the crane, to the benefit of the loading capacity of the vehicle which increases.

FWD - Fewer Welds Design
Fewer welded joints, the stronger the structure will be. Structural components made out of bended steel with a welded closing plate in lieu of four corners welded structures or monolithic structure likes those for the outer boom and sliding sections with one single welded side: balanced elasticity under load and ideal resistance to fatigue.

CQ - Cast Quality
Fassi use for more then 35 years cast components with high mechanical characteristics for various important structural components, such as the bottom section (pinion) and the head of the column, the column support, the heads of the ram rods and the cylinder bottoms, the connecting rods and other minor components: less weldings, higher performance to fatigue cycles.
