SRG Stressing Jacks
Purpose & Performance
SRG Global has a range of cable stressing units, from 10 tonne to 25 tonne, which are specially designed for use in the harsh mining environment. The air operated hydraulic powered system with a heavy duty housing and steel bodied jacks make them ideal for stressing 15.2mm strand in coal and metalliferous mines.
Use
Specifically designed as a lightweight, air operated hydraulic powered system for tensioning 15.2mm cable up to 100kN and cutting excess strand as required. The CTCD10R allows a remote controlled one man operation. A selector at the pump switches the unit from tensioning to cutting.
Suitability
- Steel bodied jack and cutter are robust for use in rough mining environments.
- Cable bolts can be tensioned to a load up to ten tonnes.
- Cutter can trim excess protruding strand.
- Low weight of jack and cutter alleviates much of the physical stress.
- Controls are suitable for one person operation.
Design
- Spark free cutting process.
- A pressure gauge and controls are fitted to the jack handle for the operator to apply more accurate loads.
- Controls fitted to the cutter handle allow direct management of the cutting process.
- Cutter safety shroud protects against cutter blade components. The cutting process is contained within the shroud.
- Cutter catcher contains any strand ejected in the cutting process.
- High quality hydraulic hoses and fittings are sleeved with wear resistant material to prevent damage. 10,000 psi hydraulic hoses are tested at a 4:1 ratio.
- The pump is contained in a heavy duty metal case.
Use
Both the CT10 and CT10R are specifically designed as lightweight, air operated hydraulic powered systems for tensioning 15.2mm cable up to 100kN.
Suitability
- Steel bodied jack is robust for use in rough mining environments Cable bolts can be tensioned to a load up to ten tonnes.
- Low weight of jack and cutter alleviates much of the physical stress.
- High quality hoses and fitting are sleeved with wear resistant material to prevent damage. 10,000 psi hydraulic hoses are tested at a 4:1 ratio.
Design CT10
- This sturdy unit requires only minimal maintenance.
- A pressure gauge is provided at the pump as a standard to enable accurate loads to be applied by the operator.
- The pump is contained in a heavy duty metal carry case.
Design CT10R
- Pressure gauge and controls are fitted to the jack handle for the operator to apply more accurate loads.
- An internal safety relief valve is fitted to prevent the unit from operating at pressures beyond its intended specifications.
- The cable stressing unit can be turned into a dual system by incorporating a remote hydraulic cable cutter.
Use
Specifically designed for use in the harsh mining environment the CT25 is ideally suited to the 15.2mm cable bolt strand and has a load capacity of 25 tonnes.
Suitability
- The PA554 pump is capable of consistent high speed operation.
- The pump is housed in a heavy duty steel tank and has a carry handle.
- Unit is supplied with an inline oiler/filter to protect the pump and ensure a long life with minimal maintenance.
- The pump is easy to operate with an internal safety relief valve and an external adjustable valve.
- A pressure gauge is provided as standard to enable accurate tensioning loads to be applied.
- High quality 10,000 psi hydraulic hoses are tested at a 4:1 ratio.
