Actuators help light up the London Eye
The British Airways' London Eye, like so many rotating structures, has a requirement to feed electric current into the rotating structure.

As rotation of this world renowned attraction is achieved through friction drives at the rim, it was technically prudent to make the electricity connection for the gondolas at the same point.
A double parallelogram floating bush arrangement was used to connect on to five current rails: each rated at 250 amps.
The floating structure compensates for errors in the roundness of the wheel, thermal expansion and other ambient effects such as wind.
The design, by Dutch construction company Hollandia, uses Servomech actuators which allow easy access for the frequent maintenance inspections that have to be carried out to the brush gear.
A Servomech heavy-duty actuator Type ATL63 provides an electrical solution that can lift with the large forces without the need for hydraulic assistance.
The actuator delivers a thrust of 45kN at a linear speed of 23mm/s.
A stroke of 600mm is achieved with a motor power of only 3kW.
Servomech actuators are supplied in the UK through Bedford company Lenze Limited (formerly Simplatroll Limited).
The Servomech design is sufficiently rugged to withstand the environment above the River Thames without special protection. Request a free brochure from Lenze ...
