Trough cover manipulators

Trough cover manipulators

To avoid cast iron cooling prior to its draining into the mixer or ladle and to ensure the effective aspiration of cast houses, the main and support troughs are covered with fixed and removable covers.


Removable covers can be lifted and moved by hydraulic manipulators, opening access for taphole machines. Using manipulators helps to fully cover the main trough and increase the safety of maintenance personnel. It also efficiently captures gas and dust through the aspiration system of the blast furnace cast house.


DHM GROUP designed a range of different models of manipulators which can be placed in optimum positions based on the individual environment of each specific cast house.
