Bachmann OO/OO9 44-0104 Narrow Gauge Timber Loco Lift
This basic wood-built hoist frame with manually worked 'block & tackle' hoist were inexpensive to construct and would allow the small quarry locomotives to be dismantled, having the capacity to lift the boiler from the frames. This allowed a great deal of maintenance including exchanging boilers to be carried out in the working galleries of quarries, locomotives only needing to be sent down the inclines to better equipped workshops when major mechanical repairs were needed.
