• Four columns structure provides the higher stiffness of load frame;
• Upper compression platen is with ball seat assembly for more accurate test;
• Dual action actuator with 150mm stroke with piston moving speed over 100mm/min; however, the piston return mode for traditional machine depends on gravity of piston with slow speed causing a lower working efficiency.
• Hydraulic power pack with AC servo motor that only operates when it is needed. It’s energy-saving, environment friendly with less oil and lower noise level.
• Larger testing space suitable for wider range of specimen sizes
• Safety covers is mounted around the columns to protect the operator, the front gate is with interlock switch to prevent machine operation when gate is open.
• Stroke protection: When the ram arrives at the upper limited position, limited switch will work to stop the motor of oil pump.
• Dual-side average extensometers or compression meter with LVDT measuring device can be selected as option with this machine for determination of Modulus of Elasticity of concrete specimen.
