and multi usage chain excavators with their high potential for loading
and performing big tasks are in great demand in the market, for the
accomplishment of big infrastructural projects. Based on their size and
working principles chain excavators can be categorized into bucket chain
excavator, mini chain excavator and hydraulic chain excavator. Though
the basic functions of these three excavators are more or less same, the
difference lies in the magnitude of the work done by them.
Hydraulic chain excavator works more or less on the same principles on
which hydraulic excavator works. Whereas bucket chain excavators are
important products designed for mining the overburden and for the sticky
bulk material. Supported by the scraper arm, the bucket chain system, is
suspended at a fixed angle from the bridge girders. Bridges are
associated with the stores which consists of two or more longitudinal
stockpiles stacked according to the windrow method. While one pile is
being stacked, the other is reclaimed at right angles to the direction
Chain excavators have their utility in big infrastructural projects.
They are mainly applied in the following fields :
- Digging of trenches to lay cables for different purposes.
- Removal of soils.
- Digging pipelines for oil, gas and water supply.
