F425RA e-dynamic

A control system developed by Fassi automatically controlling the dynamics of all the crane functions maximizing the speed of movement depending on the handled load, allowing only controlled movements and minimizing the structural stress on both the crane and the frame/sub frame of the vehicle.

Multifunction hydraulic distributor bank with digital anti-saturation system that manages the oil delivered by the pump proportionally among all the functions that require it, thereby ensuring a perfect multifunction and proportional operation.

The new-generation digital radio remote control, exclusively compatible with the Fassi product, with wide graphic display to remotely control the functions of the crane and, optionally, the vehicle and the outriggers. It automatically researches the available frequency and allows for continuous interaction between operator and crane.

A system that electronically controls the load conditions of the crane, of the hydraulic and manual extensions and of the winch, manages the lifting moment with the possibility to activate different work sectors, in relation to the stability condition of the vehicle/crane unit. In addition, it transmits and records the working data.

A security system that detects if the lateral extension supports of the outriggers are fully retracted, both for manually and hydraulically extendable outrigger supports. Linked to the height check system of the crane, at rest in the transport position, it is completed by a visualizer with visual and acoustic alarm, to install on the dashboard of the vehicle cab.

A system that proportionally distributes the oil from the pump to all manoeuvres simultaneously. It allows the operation of more functions at the same time by distributing the available oil flow proportionally to the desired functions and at the desired speed guaranteeing the perfect multifunction ability of the hydraulic distributor.

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.

A Fassi system that activates an excess of power in the most difficult situations, precisely when it’s necessary, proportionally reducing the speed of the crane movements but, at the same time, increasing the lifting capacity.

Exclusive Fassi system, built up by a longer outer lifting ram in conjunction with the linkage system, allowing to increase the working angle of the crane above the horizontal line from 10° to 15° according to the model, still maintaining in this configuration the nominal lifting performances. Prolink find application as well on the articulation ram of the jibs, with an increase of the working angle of the jib above the horizontal line from 10° to 20°.

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.

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.

Exclusive Fassi rack and pinion rotation system with gravity self centering rack guide shoe; no need of external adjustment. Low friction anti-seizure techno-polymer rotation top bush for an extra strong rotation power.

A system that allows you to select, based on operational needs, “FAST” (recycling valve activated) or “POWER” (recycling valve deactivated) while telescoping the booms. Selection is both via radio control thanks to the icon on the display or on the push button of the main control panel.
