In cable durability testing machines using hydraulic cylinders, it was necessary to repeatedly pull and slacken the cable at a high frequency.

However, the intense, repetitive motion frequently caused oil leaks. This not only worsened the surrounding environment by soiling the floor, but also raised concerns about the risk of accidents such as workers falling. A plan was made to electrify the system to improve the situation, but selecting an electric actuator that could be used under the required thrust of 25kN (per unit) and high-frequency conditions proved difficult.

While conventional electric cylinders using Ball screw raised concerns about durability, Linispeed Jack employing a robust Ball screw capable of withstanding high loads and high-frequency operation, was deemed suitable for electric operation even at high frequencies. After implementation, the biggest problem, oil leaks, was completely eliminated, and the risk of workplace accidents such as slips was removed. Not only was a clean testing environment achieved, but the maintenance effort for the hydraulic unit was also reduced.
