Roadway Support Machines
Roadway Support Machines are deployed for the installation of steel arch supports when driving underground roadways. The machines essentially consist of a support-setting device and a work platform, with the support-setting device placing the roof bars or an entire roof-bar canopy. The work platform is used as storage space for the remaining support material required, such as props, lagging, bolts, clamps, etc. and also serves as a secure base for all jobs that have to be performed at the roadhead, such as setting props, bolting together clamps, installing lagging, bolting, back-filling, etc
Generally three criteria are fulfilled by the deployment of roadway support machines:
- Improved safety at the roadhead
- Labour savings when excavating roadways
- Improved performance and thus reduced costs
GTA has developed three roadway support machines for use in different operating environments. They differ in terms of size, design and operational capabilities.
