Installed Safety Features
Several features have been incorporated into the Model 8250 to insure operator safety.
Read this section carefully before installing or using your machine.
•
Each door is made of tempered safety glass, letting you view the tests without the
danger of flying debris or specimens. The doors have safety interlocks to prevent
machine operation when any of the doors are open.
•
The latch hook is designed to positively engage the crosshead. The more weight or
force applied to the hook, the more it closes.
•
In the pneumatic mode, a steel rod, called a shear pin, holds the latch and crosshead
assemblies in a fixed position against compressed springs. The safety system ensures
the shear pin is correctly seated before operation.
•
In the event of a power loss or a loss of air pressure, the system automatically shuts
down. Air pressure is monitored at all times. The system can not operate if pressure
falls below 20 psi (140 kPa).
•
A cable tension switch and hoist height-limiting switch ensures correct operation of
the latch assembly.
•
Overpressure relief valves prevent accidental damage to the machine if excessive air
pressure is applied.
