Uses Of Pendant Stations At Your Factory

How to use pendant stations at your factory

In industries, it is required to move bulky and heavy loads, either on the floor or through aisles, and it takes time and can also cause injuries. In such cases, it is better to use overhead crane, which can easily handle and move heavy loads. Movement of these cranes is done with the help of pendant stations. A series of simple switches used to control larger electrical loads through different means is called Hoist pendant station or simply pendant station. These loads may be either hoists or cranes, but it can be used to control conveyer belt systems and production line equipment. In pendant stations, there are low power pilot duty switches connected to relays, programmable logic controllers or automation circuitry to control larger loads. Generally, pendant stations are used to move and control large cranes and hoists. Apart from this, they can be used as remote control for industrial machines.

Electromechanical devices, which are used to regulate appliances and industrial machinery are called limit switch. These switches can also be used to control cranes, as these limit the crane from lifting loads above rated capacity and are also called crane limit switches. In few cases, there are multiple switches, which are associated with crane operation. First switch gives the signal that the end of safe travel limit is being approached and therefore crane motion is slowed and the second switch indicates that it is end of safe travel distance is reached and stops the crane motion. If it is required to control the hoist motion, then there required more limit switches, and these switches provide set points for safety and reliability.

One of the challenges in crane technology is to manage cables with reliability. Festoon systems are used to support conductor cables and hoses which deliver power and control to equipment which are mobile, in an efficient maintenance free and safe method. These are cable carriers, which guide cables in their tracks and protect it against humidity and dust. In festoon systems, cables hang loose while moving, these cables can swing and get caught in crane structure, during bad weather, and this may require repairs, which is costly. Festoons are used for ship to shore cranes, and there are high winds, heavy rain and other factors, which may cause damage to festoon systems. To avoid these maintenance costs, alternative electrification system is used by crane manufacturers, it is called energy chain.
