With the widespreadization of digitalization, serious advances were recorded in machine safety technologies. But in some applications, the methods we use for years are still giving the most effective results. One of them is the emergency stop systems with rope ( finally switch ) . Best choice for most applications of the standard rope emergency stop product.
While working logic is simple, these devices can be made errors in the installation and application. This can also cause injuries, system to stop and machine damage. Below we will refer to important issues to choose the right, install and maintain these systems.
Emergency Stop Switches With Rope
Thanks to the rope (wire) extending through conveyor or machine in the emergency stop systems with rope, the operator can stop the system by pulling the rope on the where the conveyor is located. This method can stop the system by pulling the rope frequently at intervals throughout the line. emergency stop button It is more reliable and economical than put. With a single rope emergency stop system, dozens of emergency stop buttons can be provided equivalent protection. This method reduces both investment cost and maintenance cost.
For most applications, a single rope emergency stop switch can be enough for a line. The rope connects to one end switch, the other end to a wall, machine chassis or another fixed point.
Safety Switch
Also known as safety switch, the rope emergency stop switches are produced by many manufacturers on the world, the material and production quality will be noticed. When you choose your choice, you can be advantageous to choose products with high quality materials, which are made with EN 60947 standards and high quality materials.
The case quality and product protection grade are important features. With quality case material and high impact resistance, your emergency stop switches can be used for longer periods. High protection classes will protect your switch body from harmful substances such as dangerous and corrosive powder and extend its life.
Interior structure stainless steel and body plastic/composite products should be used for humid and corrosive environments.
Installation of Emergency Stop Switches
The emergency stop system can be installed easily when it is paid attention to the installation instructions. But there are some points that need to be paid attention.
The cable from the switch to the first rope/wire strap should be drawn as straight line. The cable connected with the angle of the switch will drop the working performance greatly and give the possibility to damage the switch.
In straight lines, usually the rope hanger apparatus is 3 meters distance left. For the right distance, see the guide of the manufacturer. The release of rope strap apparatus at equal intervals will ensure the system works more uniform.
Add rollers in rotations or slopes. In the middle of the rollers, the rope should enter and the groove to stop safely. With these, the rope can be pulled at 90 degrees or lower spins.
In applications where high temperature differences occur during the year, the rope tension should be controlled regularly and adjusted. In the other case, the rope can lose tension due to elongation or cause unnecessary stop operations due to shortage.
You should use the right rope for the application. Although it looks like simple, the use of false rope in many applications is observed. The use of the rope recommended by the manufacturer will give the correct result.
Extra Features
Optionally red lamp and alarm can be added to emergency stop switches. Thus, it can be seen remotely which switch is done in a system where many switches are.
Switches can be bought in 2 or 3 contact. Thus, contacts can be used for different functions, such as stop, lamp and alarm. It is also a safer system created.
New technologies are not always better than simple and proven methods, although they are giving great opportunities. Nowadays, simple work logics are the same, and are the best options to perform emergency stop tasks. With the right installation and maintenance, very long periods will ensure the safety of your business and staff.
