The high-quality spring effectively isolates the vibration generated when the machine is running and eliminates the noise caused by the contact with the building structure when the machine is running.

Surface: Anti-rust treatment of spray paint or baking paint.

The suspension spring shock absorber consists of a spring and a synthetic rubber element with a thickness of 0.3 static deflection.

Synthetic rubber elements are made together with a boom spacer bushing membrane that penetrates the hanger shell.

The inner diameter of the spring and the aperture at the bottom of the hanger shell are large enough to make the boom swing 30 degrees without touching the wall of the hole and short-circuiting the spring.

When the spring is designed, under the constant load change, it can be compressed by 50% of the rated variable pressure to be completely compressed.
