The latest MEGCIS (mechanised grouting & cable insertion system) cable bolter from GIA Industri features the latest technology with a guillotine effect cutter to ensure a cleaner and more smooth finish; an upgraded piston pump for a continuous concrete flow and reduced pulsation; and remote control operation.
The MEGCIS (mechanised grouting & cable insertion system) cable bolter provides a fast and efficient system for the reinforcement and stabilisation of roofs and hanging walls in mines and underground installations.
It has been designed to insert grout and a steel cable into a predrilled hole in variable lengths up to a borehole depth of 40m; compared with traditional rock bolts of 4 – 5m.
The units cement grouting system features a cement mixer/agitator for an optimal working cycle of 80 litres volume.
An upgraded double acting piston pump with a flow of 15 litres/min – 30 litres/min at a maximum pressure of 70 bar provides a continuous concrete flow and reduced pulsation.
The water/cement ratio is mixed in a mixer system where the grout is pumped in to the borehole with the aid of the double acting piston pump.
The pump and hose system can be cleaned separately without the need to empty the mixer.
The cable bolter features an 800m long pre-stressed 1 + 6 wire steel cable offering a low relaxation grade of 270kN and a dimension roller diameter of 800mm. Additional features also includes cable feeding and cement hose feeding depth measurement.
The bolting system has a maximum boom height of 9.104m and a horizontal reach of 7.260m to cover a boom hit area of 84m² (12m x 7m).
Remote control operation is available for improved operator visibility and safety.
The driver is also well protected by a FOPS 11 approved canopy and has a comfortable seat with armrests. An extra seat is also provided for an additional passenger. Both seats are equipped with two point safety belts.
An electro-hydraulic drive system provides low energy consumption and no air pollution
The truck has articulated frame steering by two hydraulic cylinders and a safety locking device for easy maintenance.
The utility truck is available with the option of two engines – a Deutz TCD 2013 turbo charged diesel engine rated at 113kW at rpm or a Perkins 1104D – E44TA rated at 106kW at 2200rpm.
Optional extras include an automatic fire extinguisher, emergency steering, a Xenon light on the roof – front or rear, and low smoke emission electrical and halogen free electrical cables.
