This article will take an in-depth look at cable reels.
The article will bring more detail on topics such as:
This chapter will discuss what cable reels are, their configuration, characteristics, and considerations when choosing cable reels.
Cable reels hold conductive cable or lifting cable and are used for storage, unwinding, and winding. Contacts on electric cable reels keep the power on while winding. Reels are machines that wrap long, continuous goods like cable, wires, paper, and other materials for transport or storage. Simple storage systems such as reels are available, while more advanced versions are self-winding. They can also be ordered with live connections, allowing you to utilize a hose or electrical wire while still on the reel.
There are various ways to rewind cable reels. Manual or crank, electric, hydraulic, pneumatic, and spring are some of the options.
There are five main arrangements for cable reels. Collapsible, portable, live connection, reel and cable assembly, and storage reel are some of the options.
Flange diameter, core diameter, inside traverse, the outer diameter of the cable to be carried on the reel, and the length of the cable to be carried on the reel are all important characteristics of cable reels.
The considerations when selecting cable reels include:
Requirements for Cable Length:
The different types of cable reels include:
As the name suggests, wooden cable reels are made from wood. Wooden cable reels are used in applications where heavy loads are to be carried. The wooden reels can be used to reel in wires, ropes, and electrical cables. Depending on the product to be transported, they can be tailored to a variety of traverse lengths and flange diameters.
The flanges are made first. The circular portions on either end of the core are the flanges. Two layers of lumber are attached perpendicular to each other, making one solid piece, to make a square flange. The square flange is cut into a circular shape with a bandsaw, which removes the edges. The circular flange is next rubbed to ensure a flat surface along the freshly cut edges.
Second, the flanges are tailored to the needs of the user. The diameters of the start hole and arbor hole, the number of bolt holes, and the angles of numerous holes are all common adjustments.
Third, the staves for the reel's core are formed from lumber. Because the core, also known as the drum, must form a circular, straight-edged lumber and must be rounded before being employed in this operation. Regular lumber is fed into a machine that shaves the edges off and produces a curved board known as a stave that will be used in the reel's drum. The flanges and staves are finally bolted together.
The logs are soaked and heated to soften the wood before the veneers can be cut into suitable shapes and sizes. Depending on the type of wood, this procedure can take anywhere from 12 to 40 hours. The treated logs are put one at a time onto a peeler lathe, where they are fed to a full-length knife blade. This reduces the block's diameter to about 3 to 4 inches, and any remaining wood is removed from the lathe and replaced with a fresh log. Following that, the veneer is cut into usable widths in accordance with industry standards for plywood sheets.
The veneer is frequently arranged according to its grade. This can be done by hand or with the use of optical scanners. To reduce the moisture content of the wood and shrink the veneer's size, it is stored in a low-humid area known as a dryer. The necessary portions of the veneer are then assembled using a waterproof adhesive. Normally, this is done manually. The plywood is then transferred to a hot press, which can handle roughly 20 to 40 sheets at a time, after the glue has been properly applied to the sheets. Extreme temperature and pressure values of roughly 200 psi and 310 °F are created by the hot press. This ensures proper contact between the veneer layers and allows the adhesive to perform to its full potential.
After that, the sheets are trimmed to precise widths and lengths using a series of precision saws. The grade, mill number, and other relevant information are stamped on the final plywood sheets. The cable reels can either be made from marine or shuttering plywood.
The characteristics of plywood include:
Although the name implies that marine plywood is naturally water-resistant, this is not the case. If it hasn't been treated with any chemicals, it's vulnerable to water damage. Marine plywood, on the other hand, is made of high-quality hardwood and adhered to the surface using waterproof adhesive.
You'll get robust, lightweight plywood that's defect-free if you choose higher quality grades. These characteristics make marine plywood an excellent choice for use in areas where there is water for example on ships. Marine plywood reels can be recycled into robust outdoor furniture, making the finished product more suitable for usage in coastal areas after being treated with a strong protective finish. The following grades of marine plywood are available: A, A-B, B, high density overlay, and medium density overlay.
Shuttering plywood is made of thick hardwood with a smooth film coating on both sides. It's mostly employed around building projects. Shuttering plywood is so dense that it includes at least nine layers of densely packed core veneers that are pressed together by high-pressure devices at extremely high temperatures. The ultimate product is plywood with a density of 750kg per cubic meter and a thickness of 12mm that is extremely robust. Shuttering plywood is used for heavy-duty applications where it must endure large loads.
For monofilament and insulated wire makers, plastic reels are a sturdy and lightweight alternative packaging solution. Plastic reels can be recycled completely. Makers of industrial and residential wire, with uses for electrical wiring and data transmission cables, manufacturers of ribbon and tape, and monofilament manufacturers for recreational and medicinal applications are among the current applications.
The diameter of plastic flanges ranges from 6 12" to 24". The plastic flanges can also be customized to any size. Plastic reels can be manufactured at home as long as a 3D printer is available. The benefit is that the total weight is significantly reduced. They are the only cable caps that are suited for medical technology's stringent health and cleanliness requirements.
Steel drums have largely replaced traditional wooden drums in the cable and wire business, particularly in the offshore sector. Steel drums are usually welded as fixed drums, however there are also collapsible steel drums. Steel reels or drums are made in an environmentally responsible manner and are more durable than wooden drums, although at a much greater price. Steel reels are more difficult to steal. Steel reels or drums are chosen by the offshore business nowadays over hardwood, plywood, or plastic reels or drums, although the previous land-based industry favored wooden drums due to reduced costs. Steel reels can be loaded with a variety of cables and wires, ranging from the heaviest to the lightest. These steel coils are more durable than wooden coils and are made in an environmentally sustainable manner. Cable drums that are spring loaded and can be mounted in various ways. These cable retractors, also known as spring coils, are a quick and cost-effective option for applications requiring counterbalance, recovery, or return operations.
Spring cable reels are used on a variety of moving machinery to automatically reel in cables. Most hoisting and material handling devices, such as portal cranes, grabs, magnets, lift and working platforms, machines, excavators, mobile cranes, transfer vehicles, transport systems, and skimmers in purifying plants, fall into this category. These devices are usually track-based and run in a straight line. These applications for the transmission of electric power and control signals via reeling might be horizontal or vertical in orientation.
The motor springs have a long potential length and can produce a large number of revolutions, making them ideal for retrieving and returning applications. To retract cords, cables, and hoses, the motor springs can be directly linked to a reel. The spirator spring can use long deflections, which can be used in reels like a 100-foot cable reel to reduce total package weight and space. Single or double negator constant force springs are mounted on one or two storage drums and an output drum with an inbuilt cable reel respectively, in negator spring motor assemblies. A metal base plate supports the entire structure. Other materials, such as Inconel, Elgiloy, or high-carbon steel, can be used for bespoke applications.
Spirator prestressed power springs are made by reverse winding a negator spring on an arbor and then encasing it in a retaining ring or case. If a linear motion is required, a pulley and cable attachment can be used to obtain rotational energy from the case or arbor. When deflection and torque are equal, the spirator spring takes up 20% less space than a regular power spring and produces a flatter torque gradient. Power springs can be utilized for winding, counterbalancing, and retrieving in a variety of applications. Prestressed power springs are small and light, and they can provide more than twice the number of rotations as traditional power springs. In comparison to standard power springs, higher pre-stressing allows for the use of thinner material and consequently a smaller package size.
Mobile equipment, such as gantry cranes and indoor cranes, various loading devices, large-scale open-cast mining equipment, and longitudinal scraper bridges in purifying plants and traveling platforms, facilitate the transfer of energy and data. Transmission maintenance needs a system for storing and releasing cables that is always available and follows the movement of the equipment, preferably in a synchronized manner. At the same time, the equipment's application determines the basic pattern of movement - distance, direction, acceleration, speed, and mass.
Cable reels with motor drive are a solution that fits these requirements. The reel body, drive, and slip ring assembly make up a motor-driven cable reel. Motorized hose reels, motor driven hose reels, motor driven cable reels, air hose reels, electric hose reels, and motorized hose reels are some of the alternative names for motor-driven cable reels.
This type of reel is distinguished from take-apart reels by the fact that it is permanently assembled. These reels are used to wound and unwind steel wire ropes and power cables and are found in lifting and hauling devices such as cranes, elevators, and ropeways.
Hose reels are used to wind, unwind, and store hose lengths used to transfer gasses and liquids in industrial settings. Hose reels come in a variety of materials, including steel, stainless steel, plastic, and wood. The majority of goods contain ports to keep fluid flowing during rewinding. Hose reels come in a variety of shapes and sizes.
Collapsible gadgets can be dismantled for storage or transportation. Portable hose reels, which usually have a handle, are designed to be moved by hand. Live connection reels have specific gear that keeps the material flowing while the hose is still attached to the reel. Storage reels are used to store continuous objects like cable, hose, paper, or rope for extended periods of time. A reel, hose, and integral hardware such as a nozzle make up a complete hose and reel assembly.
Hose reels can be rewound in a variety of ways. A hand crank is required for manual equipment. There are also products that use an electric motor, hydraulic motor, pneumatic motor, or internal spring. Shaft speed, terminal voltage, continuous current, continuous torque, and continuous output power are all used to describe electric motors. Operating torque, operating pressure, operating speed, operating temperature, power, maximum fluid flow, maximum fluid viscosity, and displacement per revolution are all used to rate hydraulic motors. Torque, maximum air pressure, air consumption, rated free speed, and operating noise level are all used to describe air motors.
Hose reels are useful for winding, unwinding, and storing a variety of industrial hoses. Reinforced hose comes in a variety of types, including textile braid, wire braid, wire helix, and other multi-ply or multi-layer arrangements, and is suited for heavy-duty applications. Industrial hose that has been coiled is flexible, elastic, and relatively easy to store. Corrugations, pleats, or spiral convolutions are used in corrugated hoses to promote flexibility, compression, and elongation capacity. Articulated industrial hose is made up of rigid hose sections with movable "joints" that can swivel, position, or articulate. Multiple hoses are created or glued together in a flat, ribbon, or bundled arrangement in a multi-element hose. Hose reels for pneumatic hoses and hydraulic hoses are also available.
A retractable mechanism is included in certain cable reels. The wires on these reels typically transmit mains electricity, although air hoses employ a similar method. Retractable cable reels are very handy in situations where electricity or air is required in a variety of locations. A constant force spring provides torsion for the spool in all retractable hose reels, and a ratcheting mechanism prevents the cable from retracting while in operation.
This chapter will discuss the applications and benefits of cable reels.
Cable reels are used to reel in and out the following materials:
The advantages of cable reels include:
They may not leave enough area for proper installation. When compared to trench rollers, the installation of a cable roller is rather simple. All you have to do now is locate the suitable location at the building's edge, lay down the cable, and feed the rollers into the proper position. If you can't find a good location, you may have to dig deep into the ground to put the rollers in place. If you can't manage the cable around corner bends and curves, you may need to invest in a cable roller with specific curved ends.
Cable reels hold conductive cable or lifting cable and are used for storage, unwinding, and winding. Contacts on electric cable reels keep the power on while winding.
