World’s first composite passenger lift unveiled in Singapore

World’s first composite passenger lift unveiled in Singapore

The world may soon get the first passenger lift that is made out of composite materials - and it will be produced in Singapore.

Unveiled by the Singapore Lift Company (SLC) on Wednesday (Jan 11), the lift, named “8”, uses lightweight composite materials and marks a shift away from steel - the material that is used traditionally in the manufacturing of lifts.

Established in August 2015, SLC is a joint venture between local property developer Far East Organization, construction and civil engineering firm Woh Hup and holding company Pronus (HK).

Composites include a variety of materials such as carbon fibre-reinforced polymers (CFRP), glass fibre-reinforced polymers and bio-derived polymers. Given their relative lightness, high strength and better corrosion resistance, such materials have been tapped by various industries including aerospace, deep-sea exploration and even sports like Formula One.

For example, Boeing's 787 Dreamliner and Airbus's A350 use lightweight carbon fibre composites, which are one-fifth the weight of steel but are at least five times stronger, to replace aluminium alloys in their airframes.

This will, however, be the first time that composite materials are used for lifts, but SLC’s managing director, Alister Bennett, said safety will be assured.

“We want people to feel reassured that composites are safe. They are lighter, stronger and the applications are amazing,” he said, citing the example of aluminium honeycomb panels which are used both in its lift and the 787 Dreamliner.

“The aluminium honeycomb panels are normally used on the flaps, which are lifted on the wings when (the plane) is about to land and that involves a phenomenal amount of atmospheric pressure,” he explained.

SLC has also run tests such as loading its lift with 1,600kg of weights before letting it fall down the lift shaft. “We wanted to see if it would break. In the end, the cabin was fine,” Mr Bennett said.


For now, the lift has been given a concept approval from Liftinstituut, one of Europe's certification organisations for lift and escalator systems. It is awaiting final approval from the organisation as well as the issue of certification from Singapore's Building and Construction Authority (BCA), which it hopes to receive by the end of the first quarter.

After this, it hopes to make its lift commercially available by the fourth quarter of 2017.

In the meantime, SLC will be partnering local company Admiralty International to build its lift cabins in Singapore.

Admiralty International’s director, Chia Thien Fook, told Channel NewsAsia at the launch: “We produce composite materials for boats used by the Singapore Navy and these boats that we built more than 10 years ago are still in use. People usually think that because it's plastic, it means it's not going to be lasting, but that's not true.”


A "simple lunchtime discussion" with his father over the cost and time involved in the replacement of escalators in London’s metro system, otherwise known as the Tube, was what inspired Mr Bennett to consider the use of composite materials for lifts and escalators. His father, Nigel Bennett, was the former chief executive of Hong Kong-headquartered elevator and escalator provider, Jardine Schindler.

He said: “In the London underground, some of the escalators are very old and need to be replaced in entirety. Unfortunately, an escalator is built in long sections and needs to be lifted out by cranes. In order for them to do the replacement, they need to demolish parts of the station and the construction work takes up several months and millions of pounds.

"So I started to think why not make the truss in composite so that we can flat pack it, carry it through the entrance and put it together.”

“That would save a massive amount of money and time.”

Similarly, the composite lifts will require a shorter installation time, labour and amount of construction materials, according to Mr Bennett.

While the installation of a traditional lift on one floor takes about five working days, the composite lift involves just one day’s work due to its relatively lighter weight of 150kg. A traditional lift made of steel that has the same capacity weighs about 1,500kg.

“It does away with the need for complicated shaft designs and the substantial amount of structural support in the form of concrete walls and steel supports ... which are standard requirements in current lift construction,” SLC's press release noted.

Mr Bennett said the company aims to speed up the process to four floors a day eventually, which would be a “considerable increase in productivity” and "a gamechanger in its field".

“Aside from the costs and time-efficiency benefits, the easy installation of the lift means that specialised skilled labour will no longer be required. There are currently an estimated 61,000 passenger lifts in Singapore with only an estimated 2,000 lift technicians," the press release added.

"With this innovation, any person can be trained and certified to be fully qualified to install the lift and this would reduce, to a certain extent, the labour issue for lift installation and the cost of maintenance."

Being lightweight also means that composite lifts can do away with counterweights, allowing for bigger lift cabins.

“Traditional lifts have big sections of counterweights that hang on one side … We’ve done away with that and by removing that section, we now have all the area that was used for the rails and weights to make the lift cabin,” Mr Bennett explained, noting that the bigger lift will be an added convenience for people with disabilities.

“With a minimum 1,400mm turning diameter, it is the only lift designed to enable a sufficient turning radius for wheelchairs. We want this to give dignity and be a friendly lift for disabled people.”

But the composite lift falls short in one aspect. According to Mr Bennett, the SLC’s composite lifts will not be suited for high-rise buildings that are more than 20 storeys high.

“We are initially setting a target of eight (floors) and that’s why this launch is called 8. When we get better, we’ll work to get higher … but we will never be able to do high-rise lifts because the higher and faster you go, the lifts need to be heavier," he explained, noting that the high-speed lifts installed in Taiwan's Taipei 101 skyscraper require the attachment of several weights at the bottom.

“Realistically, our lifts are a solution for low-rise buildings of less than 20 floors but beyond that, you may need a traditional lift with weights otherwise the ride wouldn’t be comfortable.”

I began my career in the banking industry in 1997, and stayed approx 6 years in it. This industry boost his knowledge about the economic condition in Indonesia, both macro and micro, and how to More understand it. My banking career continued in Yogyakarta when I joined in a program funded by the Asian Development Bank (ADB),as the coordinator for a program aimed to help improve the quality of learning and teaching process in private universities in Yogyakarta. When the earthquake stroke Yogyakarta, I chose to join an international NGO working in the area of ?disaster response and management, which allows me to help rebuild the city, as well as other disaster-stricken area in Indonesia. I went on to become the coordinator for emergency response in the Asia Pacific region. Then I was assigned for 1 year in Cambodia, as a country coordinator mostly to deliver developmental programs (water and sanitation, education, livelihood). In 2009, he continued his career as a protocol and HR officer at the U.S. Consulate General in Surabaya, and two years later I joined the Political and Economic Section until now, where i have to deal with extensive range of people and government officials, as well as private and government institution troughout eastern Indonesia. I am the founder and Editor-in-Chief in Good News From Indonesia (GNFI), a growing and influential social media movement, and was selected as one of The Most Influential Netizen 2011 by The Marketeers magazine. I also wrote a book on "Fundamentals of Disaster Management in 2007"?, "Good News From Indonesia : Beragam Prestasi Anak Bangsa di dunia"? which was luanched in August 2013, and "Indonesia Bersyukur"? which is launched in Sept 2013. In 2014, 3 books were released in which i was one of the writer; "Indonesia Pelangi Dunia"?, "Indonesia The Untold Stories"? and "Growing! Meretas Jalan Kejayaan" I give lectures to students in lectures nationwide, sharing on full range of issues, from economy, to diplomacy Less
