Loading arms

Loading arms are among the most innovative application in the Oil & Gas world. They are high-content technological systems which allow the transfer of liquid or gaseous substances.

They are generally realized without gear and they must guarantee functionality over an extended periods of time in tough environments, where the thermal gradient can really be relevant, at the point to require the resilience test at -40° as standard. The absence of maintenance is guaranteed by a greasing circuit, which allow to maintain lubrificated the rolling elements and the slewing ring raceways. The particular operating conditions require a design with significant safety factors.

Main characterisctics of loading arms slewing rings:
