About the Model:
The largest draglines ever constructed
in England at that time, have been built
by Ruston & Hornsby Ltd., of Lincoln, for
work in connection with the Indian irrigation
schemes for the reclamation of millions
of acres of barren dessert. The work involves
the excavation of hundreds of miles of canals
and the project as a whole is the largest
undertaking of its kind in the world.
In the first place only one dragline was
ordered, but this machine gave such satisfaction
that the Indian Government shortly afterwards
placed an order for a further three excavators
of the same type. At a later date six additional
draglines were ordered, and it is interesting
to note in passing that the last two machines
ordered were completed in seven weeks from
receipt of the order, a remarkable achievement
in a view of their size and complexity.
These wonderful excavators each weigh 250
tons net and upwards of 300 tons when fully
equipped and in working order.
The bucket has a capacity of 8cu.yards
and can excavate 10 tons at one cut, a rate
of working that enables the machine to load
a train of 60 wagons in an hour.
The jib is 120 ft in length (± 37 meter)
and the drag rope from the bucket 1¾" (±
44mm) in diameter. A cutting power of 30
tons is exerted on the bucket teeth.
