Hapo exoskeleton Plum for transport and gardening

The HAPO works because it redirects the effort of the upper torso (chest support) partially to the thighs using the springs.

The belt supports the lumbar region without constricting it.

In dynamic flexion, from the position of hands on the floor to the position of arms at height (at the level of the hips), it allows to support the lower back.

The Hapo was developed in cooperation with AIRBUS and SNCF.

• The load is taken off the shoulder and chest like a backpack and redirected to the thighs with the help of the exoskeleton's support structure
• The energy accumulator, consisting of two fiberglass rods, absorbs force when bending and releases it again when lifting
• It is aimed at companies looking for personalized measures to support their employees in the manual handling of loads.
• The biomechanical principle of action enables significant relief of the lumbar spine when lifting loads
• A decrease in the activity of the long biceps thigh muscle was also observed
• The HAPO is based on a three point flexion system
• With support at the level of the chest area of the lumbar belt and on the thighs
• These three support points are connected by composite springs. When handling loads, there is an impulse during lifting that helps to stand up and at the same time relieves the back and straightens the spine
