Description

Reversible mast

Technical Field

The utility model relates to a technical field of boats and ships mast, in particular to can fall formula mast.

Background

The mast is typically erected vertically from the keel or mid-plate of the vessel and may support a boom, boom or stringer. The mast on the ship is used for a plurality of purposes, such as installing signal lamps, hanging flags, erecting telegraph antennas and the like. In addition, the lifting rod can be supported to lift and unload cargos. Because the masts are vertically arranged on the ship, when the ship passes through certain bridges, the masts can collide with the bridges to influence the normal navigation of the ship due to the fact that the height of the bridge opening is relatively low and the masts are relatively too high, and therefore the existing ships can select the invertible masts to avoid the situation.

However, the existing reversible mast still has the defects that the mast damages people or damages the mast due to too high speed when the mast is laid down, and the mast is hard to lift due to higher height when the mast is lifted, so that a safe and labor-saving reversible mast is needed.
