FAQs

The LiftSuit is designed for a wide range of tasks involving frequent lifting or forward-leaning activities that place strain on the back or hip muscles. Typical applications include manual material handling, picking and packing, assembly work, and other activities where workers repeatedly bend forward or lift objects from low positions. It is particularly suitable for dynamic work environments where conventional lifting aids are impractical and unrestricted movement is required.

The LiftSuit can already provide meaningful support even when lifting very light loads or when simply leaning forward without holding additional weight. This is because you are always “lifting” and supporting the weight of your upper body, which accounts for around 60% of your total body weight.

Typically, we recommend the LiftSuit when you perform at least 30 lifting movements per hour, or when you remain in a forward-leaning position for at least five minutes per hour.

The LiftSuit is designed to provide up to 15 kg of lifting support.

This includes compensating not only for external loads, but also for the weight of the upper body when leaning forward.

Measurements conducted in our biomechanics laboratory have shown that this level of support can reduce back muscle load by up to 33 % and reduce hip muscle fatigue by up to 44 %, while lower back muscle fatigue is reduced by around 10 %. In addition, wearing the LiftSuit during repetitive lifting tasks can reduce cardiovascular load by approximately 7 %.

These values represent average results across all measured participants. The individual level of support may vary depending on the user’s body characteristics and the tasks performed.

When activated in the standard way, the LiftSuit begins to support the user as soon as the torso starts to lean forward. This typically occurs when reaching for objects below hip height. Users can activate, deactivate, or adjust the support, allowing them to decide whether they want assistance and at which torso angle the support starts.

The initial fitting takes slightly longer, as the LiftSuit needs to be adjusted to the user’s body size. When assisted by a trained expert, this typically takes around 3–5 minutes. Once the initial fitting is completed, putting on or taking off the LiftSuit usually takes well under one minute, with many users reporting around 20–30 seconds for donning or doffing.

We recommend a familiarization phase of around two weeks, during which the wearing time is gradually increased. As a rule of thumb, users typically start with around one hour on the first day and increase usage by approximately one hour every second day until they reach a full work shift toward the end of this phase.

This gradual approach allows users to get used to the new sensation of working with the LiftSuit. During the familiarization phase, we also recommend regularly checking the fit and making adjustments as needed to ensure optimal support and comfort.

In addition to subjective familiarization, one of our scientific studies has shown that this familiarization phase can significantly increase the level of muscular support, as the body and nervous system learn to rely more effectively on the LiftSuit, allowing users to get the maximum benefit from the device.

Yes. You can sit, take breaks, and drive a vehicle while wearing the LiftSuit, provided that the back support is deactivated while driving.

Make sure that all straps are properly secured so they cannot get caught on controls or moving parts, and only perform driving tasks that would also be considered safe without wearing the exoskeleton.

The LiftSuit is not a medical device. People with existing health problems – especially back, hip, or other musculoskeletal issues – should only use the LiftSuit after consulting a medical professional.

In general, the LiftSuit may only be used by healthy adults who have read the user manual and are trained in its use.

The LiftSuit requires minimal regular maintenance. We recommend the following:

• A visual inspection once per month to check the textiles, buckles, and elastic energy storage elements (EES) for signs of wear or damage.

• If any damage is detected, remove the LiftSuit from service and contact your supplier or Auxivo before using it again.

• The back EES are consumable components and should be replaced after a maximum of one year or 150,000 lifting cycles, or earlier if visible damage is present.

For cleaning, remove the EES and machine-wash the textile components according to the washing guide.
