HAPO UP: Passive Shoulder & Arm Exoskeleton for Overhead Work

The HAPO UP is a next-generation passive exoskeleton engineered to dramatically reduce shoulder strain, arm fatigue, and upper-body discomfort during overhead or elevated-arm work. Designed for professionals who rely on the endurance and strength of their shoulders every day, the HAPO UP is a lightweight, mechanical support system that actively assists your arm movement without restricting natural mobility.

Whether you're performing repetitive overhead tasks, maintaining arms raised for long periods, or working in environments that demand precision above shoulder height, the HAPO UP helps minimize muscular fatigue while supporting proper posture and joint health. This is an exoskeleton built for industries that value worker safety, enhanced productivity, and reduced workplace injuries without adding extra bulk or complexity.

Purpose-Built Support for Shoulder-Intensive Work

The HAPO UP is specifically developed for tasks performed with the arms between 60° and 180° of elevation. In these ranges, the shoulders and upper arms experience the highest strain, often leading to fatigue, poor posture, and long-term musculoskeletal disorders (MSDs). This exoskeleton provides targeted mechanical assistance exactly when it’s needed most.

As the arms rise, the HAPO UP’s articulated lever system engages, providing a supportive lifting force that reduces the load on the deltoids and surrounding shoulder muscles. When your arms return to a neutral position, the system disengages, allowing natural movement without restriction. The transition is seamless and intuitive so natural, that most users forget they’re even wearing a device.

This makes the HAPO UP ideal for:

• Construction and general trades

• Automotive and mechanical work

• Painting, sanding, electrical, and finishing work

• Warehouse stocking and elevated picking

• Assembly and manufacturing

• Maintenance, facility management, and overhead installations

• Agriculture and greenhouse operations

Any task that keeps the arms raised for minutes at a time or requires frequent upward motion benefits from the HAPO UP’s shoulder-relieving support.

Engineered for Comfort, Built for Endurance

Unlike many wearable support devices that feel bulky or restrictive, the HAPO UP is designed with comfort as a top priority. Weighing only 4.1 lbs, it remains exceptionally light for a shoulder-assist exoskeleton, making it easy to wear through long shifts without creating additional fatigue.

The structure is built around:

A Compact Spring-Rod System

The core of the HAPO UP’s support comes from its innovative spring-rod mechanism. As the worker lifts their arms, the spring-rod gently engages to counterbalance the arm’s weight. This reduces the effort required by the shoulder muscles, lowering physical strain while maintaining full freedom of movement.

Articulated Arm Supports

The support arms rest comfortably at hip level when not in use, ensuring they never get in the way during tasks that don’t require overhead lifting. Once the arms rise, the system activates smoothly, providing assistance from the moment the shoulder muscles begin working harder.

Ergonomic Fit & Adjustability

The entire exoskeleton is highly adjustable, the shoulder straps, back length, chest buckle height, belt tension, and arm supports can all be fine-tuned to your body. This ensures a personalized fit for workers of different sizes, shapes, and mobility ranges.

Breathable, Water-Repellent Fabrics

Industrial environments demand durability, but they also require comfort. The HAPO UP utilizes breathable textile interfaces to prevent overheating, and the materials are water-repellent, tear-resistant, and washable for easy maintenance.

Zero Electronics = 100% Reliability

The HAPO UP is a fully mechanical system. This means:

• No batteries to charge

• No wiring or delicate electronics

• No downtime

• No maintenance beyond basic cleaning

It’s ready whenever you are, making it one of the most dependable and cost-effective exoskeleton solutions available.

Performance Benefits That Make a Real Difference

Every feature of the HAPO UP translates into measurable improvements in worker health, safety, and long-term performance. By reducing strain and offloading a significant portion of shoulder muscle effort, this exoskeleton helps improve endurance, precision, comfort, and sustained productivity.

✔ Up to 40% Reduction in Shoulder Muscle Effort

Independent testing has shown significant reductions in the muscular load placed on the shoulders during overhead tasks. This directly lowers the risk of fatigue, strain injuries, and early-onset joint wear.

✔ Enhanced Comfort Across Long Shifts

Less fatigue means workers can maintain better posture, better control, and higher precision, even during physically demanding workdays.

✔ Reduced Risk of Shoulder Injuries and MSDs

Repetitive overhead work is a leading cause of shoulder injuries in industrial environments. The HAPO UP reduces cumulative strain, lowering workplace injury risk and associated costs.

✔ Increased Worker Efficiency and Focus

When physical strain is reduced, cognitive focus improves. Workers are less distracted by discomfort and can perform tasks more safely and efficiently.

✔ Support That Matches Natural Movement

The system moves with the user, never against them. Its natural, intuitive motion ensures full mobility and makes the HAPO UP suitable for dynamic work environments.

Fast, Easy Setup is Ready in Under a Minute

Despite its advanced engineering, the HAPO UP is extremely simple to put on and take off:

• Installation time: ~50 seconds

• Removal time: ~20 seconds

The straps, belt, and support arms are intuitive, and the adjustments stay securely locked in place. Workers can strap in and begin using the exoskeleton almost immediately, making it ideal for fast-paced industrial settings where time matters.

Discreet & Professional Design

The HAPO UP is designed to blend seamlessly into professional environments. Its compact shape and neutral colors allow it to be worn over or under various types of work clothing without drawing attention. The design emphasizes function, minimalism, and safety, with no bulky components, no unnecessary attachments, and no distractions.

Safety & Certifications You Can Trust

The HAPO UP is built to meet strict international standards, including:

• CE Machinery Directive 2006/42/CE compliance

• ISO 9001 production standard

• Manufactured by a company recognized for its environmental and ethical responsibility

These certifications ensure high reliability, quality materials, and adherence to professional safety requirements.
