It's a heavy beam, typically made of wood, that projects outward from the bow of a ship.
The anchor is hoisted and secured to the cathead when not in use, and the cathead is used to help raise and lower the anchor.
The cathead helps to keep the anchor away from the ship's side, preventing damage during anchor operations.
The stockless anchor made the cathead obsolete.
Heavy-duty Construction
Catheads are constructed from robust materials such as steel, ensuring durability and strength to withstand heavy loads and harsh marine conditions.
Multiple Grooves
Catheads feature multiple grooves or sheaves that guide ropes or cables, providing flexibility in handling different line sizes and configurations.
Manual or Mechanical Operation
Depending on the vessel's design, catheads can be operated manually using hand-operated cranks or mechanically using hydraulic or electric systems.
Secure Locking Mechanism
Catheads are equipped with locking mechanisms to secure the lines in place once tension is applied.
Corrosion Resistance
Given the exposure to saltwater and other corrosive elements, catheads used for ships often have protective coatings, such as paint or galvanization, to enhance their corrosion resistance and prolong their lifespan.
Sailing Ships:
●Purpose:On sailing ships, a cathead is a large, angled wooden beam located on the bow, used to support and secure the ship's anchor when it's not in use.
●Function:The cathead holds the anchor away from the ship's hull, preventing damage when the anchor is raised or lowered.
Oil and Gas Drilling:
●Purpose: In the oil and gas industry, hydraulic catheads are used for tightening and loosening connections in drilling operations, specifically for drill pipe and drill collars.
Other Applications:
●Nut Washer Catheads:These specialized fasteners are used in concrete wall forming, integrating a broad bearing washer and a secure fastening nut into one component, simplifying formwork setup.
●Catline Operations:Catlines, ropes powered by catheads, are used for lighter lifting tasks or assisting with maneuvering equipment on drilling rigs.
Drive Types For Catheads
Automatic tension cathead, self-tension winch
Winches designed to heave-in automatically whenever the line tension falls below a certain pre-set value. Likewise, they pay out if the line tension exceeds a pre-set value.
Manual tension cathead
Manual winch always requires a person to handle the controls for heaving or rendering.
Non-split drum cathead
The undivided drum winches are commonly found on smaller ships. It is often difficult to spool and stow the wire on such a drum satisfactorily, when wires are handled directly off the drum, the final turns of the outer layer when under tension tend to bite into the lower layer.
Split drum cathead
A winch with a drum divided by a notched flange into a tension section and a line storage section.
