Giving lock gate replacement a lift
By the time you read this, the main programme of winter stoppages for lock gate replacement should have just come to an end – but here’s a reminder of the work that’s been going on, in this case using a novel 70ft narrow-beam crane boat to speed up the process in inaccessible sites.
Independent engineering contractor the Rothen Group has been trialling its new crane working for the Canal & River Trust on three lock gate replacements in Banbury, Worcester and Warwickshire. Founder Ian Rothen siad: “Working on the canals over the past 18 years I noticed a gap in the market for a solution like this, which would make lock maintenance safer and speedier for contractors working in hard-to-reach and narrow areas of the waterways.” CRT’s Brendan Kavanagh said the new crane had “removed the need to use gantry lifting cranes when maintaining locks”, making manual lifting a thing of the past, taking the operator out of harm’s way, and knocking two days off typical job time.
It can safely lift up to 1.5 tonnes, and can be used for other heavy lifting jobs on the canals besides lock gates. Rothen Group also has a wide-beam version capable of lifting 6 tonnes.
