    Aerial Ropeway System vs belt conveyor system

    Are aerial ropeway systems in use for moving coal of 30-35000 MT per day for distance of around 5-6 km.

    What are the pros and cons for aerial ropeway system compared to say belt conveyor system.

    What is the capacity and distance beyond which cross country belt conveyor system is preferred as compared to aerial ropeway system.

    Could I get some references on the issue to study further.

  2. aerial ropeways


    Aerial ropeways as I understand it are a thing of the past. One of our cement plants has an aerial ropeway from the mine to the plant becasue of the steep incline out of the mine.

    Aerial ropeways have spillage at the loading point and have high maintenance issues with the bucket gate mechanisims. To provide the capacity, U will need a lot of buckets and when all of these require maintenance, U will have huge costs!!!!!

    The best option is belts.

  3. Dear Shri G Ravindra,

    Mr. R J Morrish has given considerate opinion / information. In brief, I can only say the following :

    1) If the terrain is very hilly and difficult, with many ups and downs, the aerial ropeway may be the only solution and will be suited for the application.
    2) One cannot easily temper / damage the aerial ropeway system. The belt conveyor system needs certain level of security. It may not be safe in a totally desolate place. It is possible that the people can damage, steal the components or even steal the material if it is like coal.
    3) Present practice is to opt for belt conveyors wherever the same are feasible. This practice might certainly have arisen from the experience of various users and people. However as said earlier there are certain areas of applications where ropeway will be more economical solution. Possibly, ropeway will have capacity limitation whereas belt conveyor of any practical capacity is feasible.
    4) The belt conveyor will generally need some kind of road along its length for inspection, maintenance, etc.

    I have a similar problem to G Ravindra. My company is about to commence a Feasibility Study on a base metal mine in a mountain location. As a part of the Feasibility Study we need to give guidance to our engineering contractors on our preferred means of transport of crushed ore from the primary crusher at the mine down to the main plant site, around 2km and 450m descent away.

    The annual rate to be moved would be 800,000 tonnes, or around 95t/hour. (based on 24hrs/day for 350 days/yr)

    I suspect that a conveyor system will not work due to the gradient and tight bends. A slurry system is not viable as water is in very limited supply, and I am starting to see that an Aerial Ropeway although 'old' technology is perhaps the most viable solution.

    Does anyone have experience of these in a modern day setting? In particular I am interested in typical unit capital costs per kilometre (perhaps you have experience of these from a previous project) and in identifying potential suppliers, who are proving difficult to find.

    I would be grateful for any ideas.

    Many thanks,
    Brett Grist

  5. G. Ravindra & Brett Grist,

    Although much depends on the terrain, you should check on the possibility of using Imperial Technologies Multi-Fold conveyor system. They have an application in Nevada, USA that involves a very steep decline.

    General information on this conveyor type can be obtained via their website and specific inform can be obtained by discussing your needs with them.

    Generally, arial ropeway systems are more expensive to run (especially with higher maintenance costs) than belt systems.

    Good luck with your evaluations.

    Two other suppliers of this type of equipment are
    Interstate equipment; and
    Dopplemayr: Http://

    There are many systems still in use in specific applications.

  7. If steep inclines and disorderly terrain is the problem, I believe the pipe conveyor system is a fairly well established solution. The only catch is that such a system would have to carry only crushed bulk - which, I suppose would be the case for an aerieal ropeway too - to be economically viable.

    FYI....Falconbridge are planning on Nickel refinery in New Caledonia - the mine is in the mountains and the plant is at the port. There plan to transport the bulk material up hill and down dale and around a few bends with a single belt conveyor...I have seen the topographic view - it will be a challenge.

    I beleive that Conveyor Dynamics and Gary James ex Bechtel fellow are involved with the design.

    Please check the Pnuetrans web site for very good information on coveying materials of this type.

    Dear Ravindra

    I do have the same question from one our client and request kindly go through the article by Mr. John Richardson, Svedela, USA, published in World Coal magazine September 2001 issue. If not everything, you might get some comparison to evaluate your project.
