KONE Win Cheesegrater Contract

Elevator firm KONE has won the contract to supply the vertical transportation for the Leadenhall Building in London, better known as the Cheesegrater.

At the heart of the system of lifts and escalators will be Kone Polaris which enables users to input their destination before entering the lift. The system even gives you time to go from the input panel to the elevator and board it, rather than taking off without you. Home floors can be programmed in so that the elevators can take people straight to a specific level via the use of a keycard, something that is particularly important for a multi-let building as the Cheesegrater will be.

It's a solution already successfully employed in British Land developments like Ropemaker Place. Preventing overloading is a safety measure allowing only the maximum capacity of the elevator car to have destinations.

Kone Polaris is rather more complex than this though as it also involves an IT system that "learns" the vertical passenger flow and then optimizes the position of the elevator cars depending on the peak times so that the right number of incoming, outgoing, and interfloor transport can be laid on for users. Limited ranges of floors can be targeted to reduce the distances that elevators have to travel with passengers filed into queues for them before they board increasing efficiency further.

The lifts themselves will be the KONE Minispace cars - these can work together in groups of up to 8 cars so an entire group of passengers can be moved at once. They reduce the need for plant machinery by having the elevator system as part of the lift shaft, and with the gearless motors are extremely smooth to ride in. These will be the workhorses of the building running at up to 4 metres a second although specially adapted with special scenic glass touches to take advantage of the Rogers designed lift shafts that will see them zing up and down the building providing great views as they go.

The contract marks something of a victory for KONE who won the original job back in 2007, but saw it cancelled as the project was put on hold. Now with all systems go again, they will soon be zooming up and down one of the tallest buildings in the City of London.
