We would like to introduce our solution for construction machinery from Higashi Hane. Powerful springs that provide great force (load) in a small space are used in hydraulics. Since painting on the springs can peel off and cause clogging, we offer powerful springs without any coating. If you are using round wire coil springs in a double configuration (where the spring is placed inside the inner diameter of the spring), please let us know. There may be potential for cost reduction by using powerful springs in a single (individual) configuration. Additionally, tension springs are used for the shift lever, and large springs are used for the tension of the tracks (crawler). Please feel free to contact us when you need assistance. *For more details, please refer to the PDF document or feel free to reach out to us.

We would like to introduce our solution "Robot Arm" from Higashi Hatsu Springs. Since the balancer spring requires a large stroke, we also have springs that are 800mm in length, which necessitates equipment for manufacturing large springs. Additionally, if more force is required, we will consider double (a specification where a spring is placed inside the inner diameter of another spring) or triple (a specification where another spring is placed inside the double) springs. Please feel free to contact us when you need assistance. *For more details, please refer to the PDF materials or feel free to reach out to us.

We would like to introduce the "Underfloor Spring" solution from Higashi Hatsu Springs. It has a proven track record in facilities such as the Nippon Budokan, which was used during the Tokyo Olympics in 1964, as well as in gymnasiums across various prefectures, schools, and police stations, receiving positive feedback. At that time, tatami mats were laid on the floor, and it seems that many people were injured on the hard tatami. It is said that coil springs and leaf springs, which excel in cushioning and have a quick return speed, are suitable for this purpose. Please feel free to contact us if you have any inquiries. *For more details, please refer to the PDF materials or feel free to reach out to us.

Commonly known vibration isolation items include elastomeric springs, air springs, and urethane. Among these, coil springs are widely used for vibration isolation applications due to their ability to accommodate a wide range of loads and ease of installation. However, coil springs themselves have very low inherent damping capacity, so it was necessary to add damping functionality individually for controlling free vibrations. By incorporating viscoelastic materials that possess this damping function, the simplification of vibration isolation and vibration reduction measures has been achieved.
