Age of the hydraulic power supply and accumulator?[edit]

AIUI, this was originally supplied from the hydraulic power station at the Underfall Yard, one of two large hydraulic stations in the docks, both at the West end, away from the Arnolfini. During WWII, bomb damage broke the hydraulic mains and isolated the bridge. As the cranes had already switched to electric power there was little need to restore the system and so it was cut short - but kept to work the lock gates, capstans and bridges around Cumberland Basin. This left the important Prince Street bridge without power. Accordingly an electric pump was installed, which remains today.

Was there an accumulator tower before this? It's not unusual to have one for a bridge (intermittent loads) at the end of a long main. Or was the accumulator only needed after the local pump was added? Andy Dingley (talk) 21:51, 5 March 2016 (UTC)[reply]

According to this NHLE record the engine house and accumulator tower is from 1879 & contains original engine & gearing.— Rod ^talk 22:24, 5 March 2016 (UTC)[reply]
