Challenge

The removal of raise bore reamers has traditionally been a hazardous, complex, costly and time-consuming process. Because of this, specialist underground mining contractor PYBAR Mining Services understood that there was a need to develop a safe work methodology to remove large diameter reamers in an underground mining environment.

Solution

The Enerpac SL100 Hydraulic Gantry System was utilized. Hydraulic Gantries are a safe, efficient way to lift and position heavy loads in applications where traditional cranes will not fit, and permanent overhead structures are not an option. Hydraulic Gantries are placed on skid tracks to provide a means for moving and placing heavy loads. The SL100 Hydraulic Gantry has a maximum lifting capacity of 110 tonnes. The SL100 Hydraulic Gantry is operated remotely, with the Intellilift wireless control system which is included with all Enerpac hydraulic gantries. The Intellilift controller offers superior safety and control removing employees from the shaft area during reamer lifts. When the reamer is lifted out of the shaft, the reamer is trammed away from the open shaft which is then covered with a hole cover to create a safe working area.

Results

The SL100 Hydraulic Gantry System was key in the success of removing the raise bore reamers in an underground environment. This was a safety win for the raise bore industry, and a much safer and more efficient way of removing large diameter reamers in an underground environment. PYBAR Mining Services underground reamer lifting gantry methodology has now been accepted as industry best practice and sets the standard for removing large diameter reamers safely in an underground environment.
