German technology company Htrius unveiled a passive exoskeleton designed to reduce the physical strain on workers installing and maintaining photovoltaic systems, solar thermal installations, and other energy infrastructure.
Dubbed BionicBack, the exoskeleton is designed to reduce physical effort during repetitive bending and lifting tasks, including mounting photovoltaic modules and support structures, laying cables, installing inverters, and handling materials on construction sites and in warehouses.
The exoskeleton provides mechanical support for the lower back during work in bent-over positions or tasks involving frequent bending and lifting. According to the company, it moves with the user without restricting mobility.
As a passive exoskeleton, BionicBack does not require batteries or an external power supply. The company says its lightweight design allows it to be put on quickly and adjusted for different users and applications.
Htrius has also developed the BionicBack FP Ready, a version designed for work at heights requiring personal fall protection equipment. The company says the system is compatible with standard fall protection equipment, enabling ergonomic support while meeting safety requirements for rooftop work, a common environment for photovoltaic installations.
According to Htrius, growing demand for renewable energy installations and a shortage of skilled workers are increasing the importance of ergonomics in the sector. The company says reducing fatigue and musculoskeletal injuries can improve productivity and support workforce retention.
