Flat-bed trolley, hospital trolley<\/td> No<\/td> Yes<\/td><\/tr><\/tbody><\/table><\/figure>An escalator is not built for a wheeled trolley. The step edge, the comb plate and the skirt gap are all wrong for it, and staff routinely redirect trolley users to a lift. In a supermarket or hypermarket, that single point decides the purchase: a store with trolley traffic that installs escalators has to add a dedicated trolley lift, while a travelator does both jobs in one machine.<\/p>
Where the question is travelator vs conveyor belt<\/strong>, the answer is just as practical. A conveyor belt moves goods on a flat surface with no handrails, no comb plates and no passenger safety chain. A travelator is a passenger-rated machine: handrails, balustrades, skirt brushes, comb plates, emergency stops, brakes and anti-reversal devices are all part of the product. You cannot substitute one for the other.<\/p>Safety and duty cycle<\/h3> Escalator risks are well documented: falls on the step band, entrapment between step and skirt, incidents at the handrail entry and at the landings. The escalator safety requirements<\/strong> that address them are mandatory on new equipment: skirt brushes and deflectors, step demarcation lighting, comb plates, an anti-reversal device, an overspeed governor, step-chain break detection and emergency stops at both landings. Moving walkway safety features<\/strong> overlap heavily \u2014 handrails, balustrades, comb plates, emergency stops, speed monitoring \u2014 with the addition of pallet run guards and, on inclined units, cleated pallets.<\/p>EN 115-2<\/strong> is worth knowing about even if you are not buying new equipment. It sets out rules for improving the safety of existing<\/strong> escalators and moving walks, and it matters when you are buying used equipment, taking over an older building, or planning a modernisation rather than a replacement.<\/p>Duty cycle should be specified, not assumed. A metro escalator may run 20\u201324 hours a day, semi-outdoor or fully outdoor. A shopping mall unit typically runs 12\u201314 hours. Office, hotel and hospital units run 10\u201312 hours. Airport walkways usually run 18\u201320 hours. Outdoor and semi-outdoor locations change the corrosion specification, the IP rating of the control system and the finish \u2014 and they change the price.<\/p>
When to Choose a Travelator, and When an Escalator Is Better<\/h2> The question of when to use a moving walkway<\/strong> and when to use an escalator<\/strong> is answered by the building, not by preference. Where a project compares travelator vs escalator vs elevator<\/strong>, note that the elevator is not in the same category: it is a vertical, on-demand machine for accessibility and short hops, and it does not solve a distance problem. The travelator vs stairs<\/strong> comparison is easier still \u2014 stairs cost nothing and are always available, but nobody pushes a loaded trolley up them.<\/p>Airports and transit hubs<\/h3> The problem in a terminal is distance, not height. Passengers with wheeled luggage walk long distances between check-in, security, piers and gates, all on one level. This is the classic case for an airport moving walkway<\/strong>. A typical moving walkway for airports<\/strong> is installed in pairs for opposite directions, with 0.65 m\/s used on the longest corridors. A travelator for airport<\/strong> terminals earns its place because the traveller walks at roughly 1.2 m\/s on a plain floor and around 2 m\/s on a moving walk, so the same passenger arrives sooner and less tired. Where the distances run into several hundred metres, the layout starts to behave more like a people mover for airport terminal<\/strong> circulation than like a simple corridor, and it has to be planned as infrastructure.<\/p>Where a terminal does change level \u2014 between pier floors, or down to a station \u2014 an escalator appears. Well-run projects combine the two: a travelator for the flat run and an escalator or lift where the level changes, rather than forcing one machine to do both jobs.<\/p>
Shopping malls, supermarkets and hypermarkets<\/h3> The trolley rule comes first. Wherever customers move trolleys, a travelator for shopping mall<\/strong> circulation is the correct machine, and this has effectively become a retail design principle rather than a preference. It also keeps the customer inside the building: the trip from the car park, through the store and back with a full trolley never leaves a moving surface. The supermarket moving walkway<\/strong> is the clearest example of the rule in practice.<\/p>Escalators remain the better answer for pure footfall between shopping levels \u2014 they are cheaper per metre of rise and take far less horizontal space in an atrium. That is why the escalator for shopping mall<\/strong> atriums is still specified for footfall, while the travelator for shopping mall<\/strong> car park levels is specified for trolleys. Large malls use both.<\/p>One planning constraint applies to both: keep uninterrupted walking distances inside commercial buildings short. Long corridors push customers out. The accepted aim is to keep distances across commercial floors under roughly 50 m \u2014 which is also the threshold at which a moving walkway for shopping mall<\/strong> circulation starts to pay for itself.<\/p>Metros, rail stations and stadiums<\/h3> This is mostly escalator territory. Crowds arrive in waves of several hundred people, and the design must follow the wave, not the average hour. For heavy-duty public transport: 1000 mm step width, 0.5 m\/s, and a standby or reduced-speed mode for the hours with no traffic. Plan the maintenance window before you plan the bank \u2014 an escalator out of service removes a large share of the capacity, and redundancy earned through maintenance downtime is often worth more than the theoretical capacity of one more unit.<\/p>
Where a station or stadium has a long transfer with a modest change of level, an inclined travelator does the whole job in one move, and avoids the queue that forms at the foot of an escalator.<\/p>
Hospitals, care homes and accessibility<\/h3> Wheelchairs, walking frames, mobility scooters and trolley-borne equipment do not work on an escalator, and an escalator is not an accessible route in any code. Where the question is travelator vs elevator<\/strong>, they are not competitors: the lift provides accessibility, the travelator provides distance. The same holds for escalator vs lift<\/strong> \u2014 an escalator is a capacity device, a lift is an accessibility device, and a compliant public building usually needs both. A long, flat or gently sloping public route inside a hospital or a care facility is exactly where a travelator removes the need for people to walk 200 m with a frame, while a lift that is sized for beds still handles the vertical journeys.<\/p>The usual arrangement for a hospital or a large care building is therefore: lifts for genuine accessibility, travelators for distance, and escalators only where visitor traffic is heavy enough to justify them.<\/p>
The high-speed travelator lesson<\/h3> Every serious attempt at an accelerating walkway has ended the same way.<\/p>
Dunlop Speedaway<\/strong>, developed from Battelle research in the 1970s, with an entry zone up to four people wide accelerating to a fast narrow lane: never put into commercial production.<\/li>\n\nTRAX<\/strong>\u00a0in Paris in the 1980s, with entry at 3 km\/h and a maximum of 15 km\/h: a technical failure, never exploited.<\/li>\n\nCNIM trottoir roulant rapide<\/strong>\u00a0at Montparnasse\u2013Bienven\u00fce, 185 m long, opened in 2002 at 12 km\/h and reduced to 9 km\/h after safety concerns, then removed in 2011 after nine years of passengers losing their balance.<\/li>\n\nThyssenKrupp Express Walkway<\/strong>\u00a0at Toronto Pearson, installed in 2007, decommissioned in 2020.<\/li><\/ul>The failure reasons were consistent: passengers lost their balance at the acceleration and deceleration zones, riders carrying bags could not use the fast section and had to be filtered out by staff, and reliability was poor. If someone offers you an accelerating walkway as a capacity or cost solution, ask for the list of comparable installations still in service. A conventional walkway at 0.5\u20130.65 m\/s does the job with a fraction of the risk.<\/p>
Escalator & Moving Walk Manufacturer<\/a><\/em><\/figcaption><\/figure><\/div>What Drives the Cost of Each<\/h2>Purchase price<\/h3> If your first question is how much does a travelator cost<\/strong>, the honest answer is that no single figure means much without the specification. The escalator cost per unit<\/strong> is easier to bracket, because the product is more standardised.<\/p>Public listings from Chinese suppliers put commercial escalators in a band of roughly US8,500\u201320,000perunit\u2217\u2217,withmostmid\u2212specification30\u00b0and35\u00b0unitsbetweenabout\u2217\u2217US8,500\u201320,000p<\/em>er<\/em>u<\/em>ni<\/em>t<\/em>\u2217\u2217,w<\/em>i<\/em>t<\/em>hm<\/em>os<\/em>t<\/em>mi<\/em>d<\/em>\u2212s<\/em>p<\/em>ec<\/em>i<\/em>f<\/em>i<\/em>c<\/em>a<\/em>t<\/em>i<\/em>o<\/em>n<\/em>30\u00b0an<\/em>d<\/em>35\u00b0u<\/em>ni<\/em>t<\/em>s<\/em>b<\/em>e<\/em>tw<\/em>ee<\/em>nab<\/em>o<\/em>u<\/em>t<\/em>\u2217\u2217U<\/em>S<\/em>9,000 and US13,000\u2217\u2217,andmovingwalksfromroughly\u2217\u2217US13,000\u2217\u2217,an<\/em>d<\/em>m<\/em>o<\/em>v<\/em>in<\/em>g<\/em>w<\/em>a<\/em>l<\/em>k<\/em>s<\/em>f<\/em>r<\/em>o<\/em>m<\/em>r<\/em>
