- Passive Drive — No Battery Required Operates entirely without motors, electronics, or batteries; delivers up to 12 kgf / 50 N·m of assistive torque from stored mechanical energy alone, eliminating charging requirements and electronic failure risk on demanding job sites.
- 5-DOF Freedom of Movement Five degrees of freedom including driving rotation and length adjustment, with a waist bending range of approximately 150 degrees, accommodate the full range of lifting, carrying, and bending postures in construction and logistics environments.
- Dual Operating Modes Walking mode and working mode allow the wearer to switch between unencumbered transit movement and maximum lumbar support during active material handling, reducing unnecessary resistance during movement.
- Body-Adaptive Harness Design The harness is tailored to body type with an easy-detachment structure, enabling rapid donning and doffing and ensuring a secure, personalised fit for workers across different body types.
- Hybrid Module Expandability A hybrid module design supports replacement and expansion of components, providing long-term adaptability and enabling customisation for specific industrial application requirements.
Description
The iTR Lumbar Passive Assistor is a lightweight industrial back-support exoskeleton engineered to reduce lumbar strain during heavy manual material handling. Weighing just 2.7 kg, it operates entirely without batteries, motors, or electronic components — a passive drive mechanism delivers up to 12 kgf (50 N·m) of assistive torque at the lumbar region when the wearer bends forward to lift or carry loads. This mechanical assistance supplements the worker's own musculature precisely when it is most taxed, reducing cumulative spinal load over a full working shift without battery charging or power management.
The harness is tailored to body type with an easy-detachment structure and a hybrid module design that allows expansion and replacement. With 5 degrees of freedom — including driving rotation and length adjustment — and a waist bending range of approximately 150 degrees, the Lumbar Passive Assistor accommodates the full motion envelope of construction and logistics tasks. Two operating modes — walking mode and working mode — allow workers to switch between unencumbered movement and maximum assistive support as the task demands.

Frequently Asked Questions
The iTR Lumbar Passive Assistor is a wearable passive exoskeleton designed to reduce lower back strain during heavy manual material handling tasks. It is used by workers in construction and logistics environments to supplement lumbar musculature support during repetitive lifting, bending, and carrying.
The passive drive system stores mechanical energy — using springs or elastic structural elements — and releases it as assistive torque when the wearer bends forward under load. This delivers up to 12 kgf (50 N·m) of lumbar support without any electrical power, battery management, or risk of electronic failure.
The Lumbar Passive Assistor is primarily designed for construction and logistics industries, where sustained manual material handling creates cumulative lumbar load. It is also suitable for any industrial setting involving repetitive heavy lifting, carrying, and bending postures.
