Cable Roller Assisted Pull Down Systems (CRASDS) are used so the cable being pulled is run along the metal roller and not on the floor. Usually the cables are placed on a workbench in an area where it is protected from moisture and vibration. They come in a wide range of sizes and are able to hold various amounts of weight depending upon the required size of cable. They are also suitable for applications having sharp turns and inclines. Some systems have automatic brakes which operate on a delay to provide more control.
There are many advantages to using a cable roller. One such advantage is the use of a single cable rather than multiple parallel cables. The system is able to provide smoother pulls because one cable pulls all of the cables around corners and other tight areas. This reduces the amount of wasted energy and reduces the chance of the cable being pushed around. They provide a consistent and reliable pull down operation.
Another advantage is that the cable roller system is self contained. It is protected from vibration and moisture and requires no external power source for its operation. The system does not require any type of external power cable connection points or any type of electrical wiring. They do require a steel construction for support. The steel construction should be tightly welded to provide a sturdy foundation for the cable pulling process.
These types of rollers can pull up to twelve cables at a time. They can be used in different sizes depending upon the job that needs to be accomplished. The bigger the job the larger the number of wire cable rollers required. The wire cable rollers can be powered electrically or mechanically. Most are powered mechanically and can be powered by an extension cord, power cord, or electrical outlet.
There are some jobs where the need for cable roller systems is very important. Some construction jobs require extensive construction and are best completed with heavy duty cable rollers. Cable laying is another type of job that cable rollers are frequently used for. Cable laying machines are often used when installing wires, lighting, and ventilation ducts. There are many different types of cable pulley systems to choose from when purchasing cable rollers.
There are a few important things to consider before making a purchase. Each type of cable roller system is designed for a certain job. It is important to know what type of job the cable roller will be used for. The size of the job, the type of wire or cables, and the amount of traffic in the area will see all influence the size and weight of the cable roller system that is purchased. The list type cable roller is probably one of the most popular types on the market today.
