Lock gate re­pair­ers in deep wa­ter…

Canal Boat - - News -

IT MIGHT NOT look par­tic­u­larly huge when seen float­ing in the Thames amid East Lon­don’s fa­mil­iar sights, but this is ac­tu­ally one of the largest lock gates on the Canal & River Trust’s net­work – so big and heavy (at al­most 40ft by 50ft and weigh­ing 160 tonnes) that the most prac­ti­cal way of tak­ing it away for re­pairs was to tow it down the tide­way.

It’s also one of the prici­est: at £ 920,000, the project to re­fur­bish a pair of steel gates fit­ted in 1929 to the en­trance lock to West In­dia Dock on the Isle of Dogs was the sin­gle largest job in the Trust’s win­ter lock main­te­nance pro­gramme.

The work in­cludes up­grad­ing the gates to with­stand cor­ro­sion, main­te­nance to the pin­tles (the piv­ots that sup­port them), and re-lin­ing the wa­ter­tight seals be­tween the bot­tom of the gates and the lock floor.
