Viking Containment uses thousands of sandbags and ballast tubes per annum to protect and temporarily ballast its liner projects during and post installation. To increase efficiency and minimize repetitive strain and manual handling type injuries the company has designed a purpose-built mobile conveyor hopper system for filling the sand bags and ballast tubes.

The conveyor has telescopic legs which are set to the required height. The hopper is then filled with sand which feeds the conveyor belt. A variable speed foot controller is used by the operator to adjust the filling rate through the chute.
