  • The crane arrives at GairlochyEarly morning on day 1. The 200 tonne crane arrives at a sunny Gairlochy accompanied by over 600 cyclists who also arrived at Gairlochy as part of the Maggie's Bike & Hike event!
    Building up the canal bankThe canal bank needed to be raised to create a hardstanding for the crane to reach the right height to lift the lock gate out. An area of 20 x 11 metres was covered using 320 tonnes of crushed rock.
    Swinging the walkwayLate morning on day 1. Slings and chains are fitted to the walkway along the top of the lock gate so the crane can move it out of the way.
    Cutting the lock gateEarly afternoon on day 1. Bracket bolts are being cut off the lock gate to allow steel needles to be inserted and attached to the crane.
    Crane begins to lift lock gateEarly afternoon on day 1. The crane begins to lift the largest gate (24 tonnes) on the Scottish Canal network out of the water.
    Moving into positionEarly afternoon on day 1. The massive lock gate is moved into position on land. The area below the white line is usually hidden in the water!

    The largest lock gate on the Scottish canal network had to be repaired after one of the heel posts burst bringing sea-to-sea transit on the Caledonian Canal to a standstill.

    After initial inspections it was found that the pot and cup mechanism at the bottom of the lock gate which enabled the gate to swing had burst. The lock gate would need to be taken out, repaired and reset.

    The gate itself is a massive 24 tonnes, at a height of 10.5m by 7m wide. It would need a large crane to lift it out, and so a 200 tonne crane was brought up from the Central Belt.

    Over the course of a weekend, the crane operators, a team of divers, and Scottish Canals staff worked hard to repair the broken gate and get the canal back open to boating traffic.
