Reels are revolvable devices around which lengthy, continuous items such as cable, wires, paper, etc., are wrapped for transportation or storage. Reels are available as simple storage devices although more advanced styles are self-winding. They are also available with live connections that allow an item like a hose or electrical cable to be used while still on the reel. Typically reels are sold as individual items. Hose and cable are not supplied. A cable reel is a reel that carries a conductive cable or lifting cable. A hose reel is a reel that carries a hose for use with gas or liquids. A storage reel is a reel that carries items other than cable or hose, such as paper or rope. Live connection reels are outfitted with connection hardware to allow electricity / air / gas / liquid to be passed through it while the hose or cable is still on, or partially on, the reel. A reel assembly includes a reel, a wire and possible features mounted on the hose or cable. An example would be an electrical cord, on a reel, with a light attached.
Materials of Construction
Depending on the application, light, medium or heavy-duty reels can be designed in a number of different materials. Materials of construction used for reels include wood, steel, stainless steel, and plastic. The metals are typically used for more heavy-duty applications. Plastics and wood are used for lighter and medium duty applications.
Important specifications for reels include flange diameter, core diameter, inside traverse, the outside diameter of the cable or hose to be carried on the reel, and the length of the cable or hose to be carried on the reel. The flange diameter is the outside diameter of the reel flange. The core diameter is the diameter of the interior of the reel or core. The inside traverse is the distance from inside to inside of reel flanges.
Reels have several rewind options. These include manual or crank, electric, hydraulic, pneumatic, and spring. In a manual or crank rewind reel no rewind mechanism is associated with the reel. A hand crank or other manual method is required to rewind the hose or cable. For electric, hydraulic, and pneumatic rewind reels a motor drives the rewinding of the reel. A spring rewind reel uses an internal spring to rewind the wheel. Features common to reels are portable and collapsible construction. Collapsible reels can be collapsed or broken down for compact storage or bulk shipment. Portable reels are hand transportable. They are supplied with a lifting handle.
