Lock gate production enters new era

We're announcing the biggest change in lock gate manufacture since moving from steam to electric machines.

We're investing in new technology at our lock gate workshop in the West Midlands that will allow us to increase production of lock gates to keep up with the demand for replacement gates across our 2,000-mile canal network.

The new custom-built CNC machine will be the largest of its type in the UK – and the third largest in Europe – to allow for the size and scale of the canal network’s bespoke oak lock gates.

Largest in UK

Built by specialist fabricators in Europe, the ‘computer numerically controlled’ machine is expected to be delivered to the Trust’s Bradley-based workshop early next year.  It replaces largely obsolete machinery dating back 60-70 years and will enable the Trust’s two workshops to incrementally increase production to around 190 lock gate leaves every year, up from around 150 lock gate leaves at present.

Simon Turner, workshops manager, comments: “The arrival of new computer-based technology to help our craftspeople produce lock gates is the biggest update in our workshops since electric machinery superseded steam-powered machinery which, in turn, superseded the hand tools used by the original canal builders.

Bow wave of new lock gates

“The canal network has a bow wave of new lock gates needed in the years ahead including, for example, replacing the many gates installed as part of the canal restorations around the Millenium that are now nearing the end of their working life.  This investment in production will allow us to keep up with that demand, with the new machine able to precision cut the oak components needed to make the gates quickly and efficiently.”

The investment by the Trust of c£750,000 was brought forward by the workshop team under the Trust’s ‘Spend to Save’ scheme, where investment is made today to deliver future efficiency.

The Trust has two lock gate workshops, at Bradley in the West Midlands and Stanley Ferry in Yorkshire.  The smaller lock gates leaves found across much of the network are mostly built at Bradley, whilst Stanley Ferry has the lifting capacity to also make the network’s largest gates, notably those on larger river navigations.  The new CNC machine will be based at Bradley but will cut component parts for both sites.  The workshop teams will continue their skilled work to hand assemble and finish the lock gate leaves.
