Sample Research Paper on Mitsubishi Escalator


Since the 1930s, Mitsubishi Electric has become a major contributor in terms of vertical movement in offices, factories, and even homes. The company is the chief manufacturer of both linear and spiral escalators. The spiral escalator, for instance, has made movement around buildings more comfortable, safer, and more convenient. The linear escalator comes with décor that fits well in different building designs. The escalator incorporates a motor-driven chain with linked steps, which move up and down the track, enabling the linked steps to remain in horizontal position. The Mitsubishi escalator is driven by alternating current motors that allow the system to move at a constant speed.

Most of the escalators that Mitsubishi Electric has designed have the same basic structure as a standard escalator. The main components of a standard Mitsubishi escalator are:

  1. Landing platform
  2. Truss (inclined section)
  3. Tracks
  4. Escalator steps
  5. Handrail
  6. Balustrade (escalator exterior)
  7. Drive system
  8. Auto-lubrication system
  9. Safety devices
  10. Electrical and control systems

However, escalator-related injuries and deaths have been reported in various places around the world, thus, compelling the company to enhance safety measures on its escalators. Failure in any constituent of the escalator can result to risks. Some of the system risks failure include mismatch in electrical control system, change in performance parameter in drive system, and surface crack on the steps.  Escalators have also become health risk due to the number of people using them each day. People are advised to use hand wipes while holding handrail to avoid contracting germs.


The conveyance devices have become a fundamental part of life for millions of people throughout the globe. Escalators have transformed people lives due to their ease in operation and assurance of safety on their use. Escalators are usually large and quite complicated to install. They require a high level of engineering and manufacturing standards in order to enhance safety throughout their operation period. Safety is a major issue in the installation of escalators. Every year, tens of thousands of people are rushed to hospitals due to escalator accidents. Some of the risks of using Mitsubishi escalator include falling and being caught at the top or the bottom of the escalator. Children are always at a higher risk than adults because they are not quite cautious.

To ensure safety while using escalators, Mitsubishi Electric has endeavored to refine its system technology through innovation and regular check-ups. The grooves at the corner edges of each step prevent people from slipping, in addition to enhancing visibility on the steps, particularly during the downward movement. The comb’s teeth at either side of the track are designed with smaller angles to minimize the risk of being trapped on the steps. A skirt obstruction device is normally used to stop the escalator in case a person is trapped. Some of the recommendations made on safety include limiting escalator use for people under alcohol influence and employing guiding personnel to assist elderly people who frequently use escalators.


The Mitsubishi escalator has managed to meet customer expectations through innovation and technology that function to guarantee safety. Mitsubishi Electric has set high standards in escalator innovation by making the vertical transportation requirements quite efficient with a lot of fun. For the last 20 years, no other company in the world has managed to beat the magnificent installation of the spiral escalator. Escalators have become part of life in many cities, thus, Mitsubishi Electric cannot afford to risk the lives of millions of people globally through faulty systems. However, escalator-related accidents have resulted to medical consequences due to fall and trapping. Malfunctioning of different components of the escalator can lead to injuries. To enhance safety, an emergency stop button is placed at the bottom and the top of the escalator where users can press with ease.
