Offshore Crane Main Boom Luffing Cylinder<\/h2>\n

Lifting 100-tonne loads from a supply vessel to a platform deck \u2014 40 metres above the waterline, in 3-metre swells. The main boom luffing cylinder raises and lowers the boom through its full arc, controlling the reach and height of every lift with 8,454 KN of thrust.<\/p>\n

How the Main Boom Luffing Cylinder Controls Crane Reach<\/h2>\n
<\/div>\n

\"Offshore<\/p>\n

An offshore crane sits on a pedestal mounted to the deck of a platform, FPSO, or construction vessel. The main boom pivots at its base \u2014 the luffing cylinder pushes the boom upward (increasing the boom angle, reducing reach, increasing height) or allows it to lower (decreasing angle, increasing reach, reducing height). The operator controls the boom angle to position the hook precisely over the load \u2014 which may be on a supply vessel heaving 2\u20134 metres in the waves.<\/p>\n

The 5,635 mm stroke covers the full boom arc from near-horizontal (maximum reach for loading from supply vessels alongside) to near-vertical (stowed position for storm survival). The 8,454 KN thrust must overcome the boom weight, the suspended load, wind forces, and the dynamic acceleration from vessel motion \u2014 all simultaneously.
