At SEMI, we continue to advance our commitment to safety and continuous improvement in Live-Line Work (LLW). Since mid-2025, all our crews have a new ally in their daily operations: the “HADAS“, an assistance system inspired by the automotive sector’s ADAS that we have pioneered in adapting for LLW buckets.
What are “HADAS”?
They are compact devices installed in the elbow of the bucket that emit visual and acoustic alerts when they detect an unsafe approach to energized lines. Their function is to assist and reinforce supervision, especially that of the Crew Leader, without replacing existing safety procedures or elements.
An innovation developed from experience
A joint project was initiated with the manufacturer to adapt and reconfigure the device for this new application. Laboratory and field tests were conducted, adjusting:
- Sensitivity and voltage levels
- Response to boom movement
- Parameterization of alerts
- Safe installation and removal procedures
The result is a more operational, durable, and effective system that adds an additional layer of prevention in the most delicate maneuvers.
SEMI, a pioneer in the sector
SEMI is the first company in the sector to implement this device in this specific configuration. The initiative has been presented in various forums and technical meetings, receiving an excellent reception from both clients and professionals in the LLW field.
Added value for the crews
Field teams and, especially, Crew Leaders have highly valued the “HADAS”, highlighting:
- Their capacity to support decision-making
- The increase of control and safety in risk areas
- The ease of use and integration into the daily routine
Innovation with real impact
For us, innovation is only true innovation when it is successfully applied and improves safety. The “HADAS” represent exactly that: a practical, versatile solution with great potential for application in other equipment working close to energized facilities.
At SEMI, we continue to share initiatives that add value to the sector and contribute to building increasingly safer work environments.
