Limitorque upgrades Historic Thames Lock

Limitorque has been awarded a contract from the Port of London Authority for the retrofit of electric actuators, as part of the Authority’s maintenance and renovation programme. Richmond Lock, on the River Thames, is a half-tide lock and weir, with lifting sluice gates and has been an integral part of the riverside scenery for over a century. It was built in 1894, following Royal Assent from Queen Victoria, to reduce the tidal influence on this section of the Thames and to open navigation to the upper reaches of the river. Limitorque electric actuators have been reliably driving the gates since the early 1970s, when the operating mechanism was first motorised. Following success in the recent tender process, Limitorque actuators have again been selected to replace the existing units. The latest machinery will use the rugged, vandal-proof design L120
series actuator, to ensure maximum protection and reliability.
