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.


Cable Tensioning Cutting Unit CTCD10R

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.

Cable Tensioning CT10 & CT10R

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.

Cable Tensioning Unit CT25

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.
