Series 315 Load Frame 26 Operation
Crush Point Hazards
It is important to stay clear of any potential crush points when the system is
operating. You should know where the crush points are in your system
and protect yourself and others from those crush points with appropriate
safety devices. The following paragraphs describe crush points and
precautions to take while working around crush points.
Locations A crush point exists between the platen and crosshead on load frames
where the actuator piston rod and specimen move (both areas are shown).
Another potential crush point exists where the lower end of the actuator
piston rod extends below the platen and the bottom of the load frame/load
frame.
Precautions Keep clear of any mechanical linkage that moves within a closed area. If
the linkage should move (when the system starts or due to mechanical
failure), very high forces can be present that could pinch, cut, or crush
anything in the path of linkage movement.
Never allow any part of your body to enter the path of machine movement
or to touch moving machinery, linkages, hoses, cables, specimens, etc.
These present serious crush points or pinch points.
