1. Mobile Stacking Bridges

Mobile Stacking Bridges

Mobile stacking bridges are suitable for fast advancing dumps with small dumping heights for deep and high cast operations.

Mobile Stacking Bridges (MSBs) are designed for fast advancing dumps with small dumping heights for deep and high cast operations. MSBs consist of several, up to 100 m long, straight connected bridge segments with separate single or double crawlers and a single bridge belt conveyor. The material is dumped by a short, slewable and, if required, liftable discharge boom which is integrated in a tripper car traveling across the entire bridge length.

MSBs are able to dump circle-shaped dumps in a slewing mode operation or rectangle-shaped dumps in a parallel mode operation. With a retractable discharge boom it is possible to dump both a low (max. height per geotechnical and safety requirements) and high cast (up to 8 m high) at the same time.

TAKRAF stacking bridges with total lengths between 300 m and 500 m are working in Chile and Mauretania (500 m³/h to 5,000 m³/h).

    Leach Pad Stacking & Reclaiming System Gaby

    The application of mobile stacking bridges (MSB) is not restricted to operate on ON-OFF heap leach systems. The biggest advantage of the crawler mounted mobile stacking bridge is the continuous operation without interruptions (downtimes) to shift or relocate. MSBs are designed with a minimized number of bridge segments with the advantages of:

    • less crawler units, less maintenance, less complex equipment control (leveling),
    • reduced operating expenses,
    • more reliable structural design according to fatigue loads (bolted instead of welded). A retractable tripper stacker conveyor allows dumping on both sides of the bridge (low and high cast operation).

    Heap Leach Stacking System with Mobile Stacking Bridge and Cross Conveyor

    TAKRAF supplied the copper ore leaching system consisting of the agglomeration plant, the on/off leach pad, as well as the waste disposal facility.

    The Mobile Stacking Bridge (MSB) forms part of the stacking and reclaiming system for the on/off heap leach pad.

    The application of MSBs is not only restricted to operating across on/off heap leach systems and the technology can be applied across a wide range of areas. The most significant advantage of the crawler mounted MSB is its ability to operate continuously without interruption and do not require any downtime to shift or relocate.

    MSBs are designed with a reduced number of bridge segments which provide the following advantages:

     

    • Fewer crawler units being required which results in lower overall costs, decreased maintenance and decreased equipment control (leveling) complexity
    • Reduced operating expenses
    • Increased structural design reliability according to fatigue loads (bolted instead of welded). A retractable tripper stacker conveyor allows dumping on both sides of the bridge (low and high cast operation)
