Creep Testing Machines with Lever and Weight Mechanism
LABORTECH offers testing machines for long-term C.1 tests, where a constant load is obtained by means of a lever mechanism and a weight.
All modifications to the CREEP C.1 testing systems that we manufacture are designed so that the customer can fully rely on their operation and accuracy under long-term constant load (material flow) with force or tension, including elongation, and at a homogeneous and constant temperature in a high-temperature oven, with reliable results, even after 100,000 hours of continuous load.
