Lifts, escalators, and moving walkways

Lifts, escalators, and moving walkways

Lifts

  • Lifts, also known as elevators, are used for vertical transportation of people or goods.
  • These systems are essential in high-rise structures to efficiently move people between different floors.
  • The key components of a lift system include the lift car, a counterweight, a machine drive system, and a control system.
  • The operation of lifts relies on the principle of balance, with the weight of the lift and its load balanced by a counterweight.
  • Lift maintenance is crucial to ensure safety, smooth operation, and to prolong the useful lifespan of the equipment.
  • Lifts are also designed to comply with accessibility requirements set out in building regulations to facilitate the movement of individuals with mobility impairments.

Escalators

  • Escalators are a type of moving staircase designed to transport people between different levels in a building quickly and effortlessly.
  • They are commonly found in public transport facilities and commercial buildings due to their high passenger handling capacity.
  • A typical escalator system consists of two conveyor belts (the steps and handrails), electric motors, tracks, and control systems.
  • Escalators work on a continuous loop system, allowing constant movement and efficient crowd control.
  • Regular maintenance, such as cleaning and lubrication, is necessary to minimise wear and tear.

Moving Walkways

  • Moving walkways, also known as travelators, provide horizontal or slight inclined movement, aiding in the transport of people over short to medium distances.
  • Like escalators, they also work on a loop principle, with a surface for standing or walking that moves at a constant speed.
  • Often found in airports, shopping centres, and subway systems, they help in maintaining a steady flow of foot traffic and cutting down transit time.
  • They consist of a motor, drive system, control systems and moving belt.
  • As with lifts and escalators, regular maintenance of moving walkways is crucial for safety and operational efficiency.

Safety and Regulation

  • All three systems - lifts, escalators and moving walkways - are subject to stringent safety regulations and standards.
  • Risk assessments are regularly conducted to identify and mitigate potential safety hazards.
  • In case of emergencies or power outages, all three systems should have suitable safety measures in place, such as manual control systems or brake systems.
  • All installation, repair, and maintenance work must be carried out by a competent person or under their supervision, according to health and safety regulations. -Regulations, codes of practice and standards related to these transportation systems vary by region and should be checked with local authorities.
