- Load frame: The frames all incorporate human factor considerations in the design to ensure safety, reduce
operator fatigue, and provide the highest level of flexibility. Extremely robust crosshead guidance is incorporated
in all frame designs providing the highest level of lateral crosshead stiffness. - High accuracy: The preloaded precision ball-screw with high speed & low noise ensures high speed and position
measurement accuracy and less noise. - High stiffness frame: The load frame is with 4 columns and heavy duty pre-loaded bearings. Preloaded ball screws,
precision guidance columns, and a symmetrical drive system improve frame stiffness and alignment - Safety features: The testing machine stops automatically when the change in the test force exceeds a specified
value during operations. - Over-travel limits: Dual over-travel limits, located on the front console, help prevent crosshead overshooting and
sensor overloads. A graduated rule along the column can be used to preset these limits to specific distances.
