The HCT-28 combines electromechcanical load application with dead weight long term creep tension.
The load frame includes crossheads and frame.
The crosshead connects to the front crosshead through adjusting screws.
The front grips and load cell are fixed to the crosshead.
The rear grips connect the rear crosshead by tension rod and rope.
There is one linear bearing between tension rod and bracket.
That makes a coaxial force and also lowers the friction.
After the specimen is clamped, the specimen will be pre-tensioned by the crosshead.
The turning bracket amplifies the tension load from the weight and applies the load to the tension rope.
This configuration passes the load to the specimen through the tension rod and grip.
The load is then measured through the load cell mounted on the grips.
Specifications:
- Maximum creep test: 28KN (6,300 lb)
- Load applied: Pre-tensioned by screw. Creep load by weight.
- Load measured by load cell and computer display.
- Test space: 20,000-25,000mm (65 ft – 82 ft)
- Weight: Approximately 6 metric tons.(13,300 lb)
