When required to flex its lifting ‘muscles’, the leviathan makes use of a simple yet ingenious principle. The opposing gondolas are each filled with 300 tons of water and, as a result, balance each other out. Consequently, the drive does not have to do any lifting but merely overcome friction. Torque is generated by ten hydraulic motors grouped concentrically around the rotational axis located in the reinforced rear concrete pylon. Together with an emergency generator and transformers driving the wheel, the hydraulic pumps that propel the motors are located on three levels underneath the wheel’s bearing. The hydraulic motors work using a 1:100 ratio on the gearing of the rear bearing and simultaneously function as brakes.

To ensure a smooth hydraulic operation, Scottish Canals commissioned the electrohydraulic specialist Denley Hydraulics in England’s West Yorkshire, who in turn took KTR on board for the demanding project. In addition to ROTEX flexible jaw couplings, which are installed between the motors and pumps, the hydraulic units also feature KTR bellhousings and damping elements.

While Nessie has been ingrained in the human collective memory as a cryptozoological hybrid from prehistoric times, the Falkirk Wheel is perceived as a technically aesthetic fusion of modern-day engineering and design. So much so that the Royal Commission for Fine Arts ennobled the ship's lift as a “contemporary sculpture”. The captivating ship-lifting giant has not only made it into London's Victoria and Albert Museum in the form of a model, but from 2007, it has also adorned the rear side of Scottish £50 notes (series 2007 – 2011) issued by the Bank of Scotland.
