The utility model discloses a marine cabin hanging beam, including at least two rotation seats, rotate seat fixed mounting on wall or stand. Rotating the seat and being connected with the dwang realization rotation of vertical setting, the dwang can revolute the rotation that the axial of moving the seat realized certain angle. Fixed connection sets up hoist and mount pole and bracing piece respectively on the dwang, can form confined triangle -shaped behind dwang, hoist and mount pole and the bracing piece three reciprocal anchorage, plays the effect of outrigger. Be provided with hoist and mount on the pole in hoist and mount, through the hoist and mount piece heavy object of hoisting. Passed through dwang, hoist and mount pole and bracing piece by the gravity of the heavy object hoist and transmit for rotating the seat, bear by rotating the seat. The structure of running seat can make dwang, hoist and mount pole and bracing piece realize rotating, when needing the when used to forward it to desired position, can make its position of rotating the wall under the state that does not use, has reduced the space that takies, is applicable to narrow and small space in the marine engine room.
