Safety Cables –
One of the problems
in the operation of equipment in the aerospace and aircraft industries is
vibrations that can loosen fasteners, which can be a severe safety hazard.
Although fasteners may be mechanically tightened to ensure they are held in
place, there is always, especially with the stress that aircraft has to endure,
the chance of a connector coming loose.
The first attempts
to prevent the loosening of fasteners was the installation of safety wires.
Several problems arose from this method, which included the wires breaking or
being unable to keep the fasteners secure enough to stop them from loosening.
The wires had to be constantly inspected and changed multiple times causing
delays and unnecessary repairs.
In the early to
mid-80’s, with the realization that a sturdier device needed to be created, aircraft
engineers designed and developed the safety cable, a more substantial
alternative to wires. Using tightly wound strands of wire, with dimensions
equivalent to a single wire, safety cables were developed to provide guaranteed
retention of fasteners. The multiple wire design enhances the strength of a
single wire and increases protection from vibrations and kinetic energy.
Unlike the multiple
repairs and tedious installation of wires, light weight safety cables can be
easily installed and do not need to be inspected, monitored, or checked. It is
a simple matter of set and forget. The strength of safety cables ensures that
they will maintain consistent tension regardless of the intense stress during aircraft
consideration for all industries is safety, especially in high risk ones like
aerospace and aircraft manufacturing. Prior to the implementation of safety
cables, wires had the potential of inflicting personal injury or coming loose
midflight. Safety cables have been purposely designed to prevent these hazards.
The tight winding of the wire, with the use of multiple strands, keeps any
single wire from being a possible hazard.
Whenever there is an
innovation or new process, the first thing that comes to mind is how to train
employees to implement the new concept. Safety cables are designed to be easily
installed without the need for instruction or training. Since the connections
between fasteners is very clear and straight forward, cables can be easily fitted
In the aerospace and
aircraft industries, there are many facets of their operations that need to function
without the need for constant monitoring and inspection. This is true from the
smallest component to the most critical. The use of safety cables, to keep
fasteners in their proper position, is another means of keeping everything
running safely and smoothly.
