How is the pendant of the BAK 14 raised?

The pendant of the BAK 14 is raised using torsion springs. Torsion springs store mechanical energy when twisted, and as they unwind, they provide the necessary force to raise the pendant. This mechanism is advantageous for applications that require a smooth and controlled lifting motion, as well as for maintaining the pendant's position once it is raised.

Utilizing torsion springs allows for a lightweight and efficient design, which is especially beneficial in aerospace applications where weight is a critical factor. The springs work by exerting a torque that assists in lifting the pendant against gravity, making them an ideal choice for this type of mechanism. In the context of other potential options, hydraulic pumps and electric motors would require additional components and increase complexity, while counterbalance weights might not provide the precise control needed for raising the pendant. Thus, torsion springs are the most suitable and effective means for this operation.
