To be combined with several transportation chairs

When transporting patients, often they have to be carried up and down stairs, either from and to the patients’ apartments, or their houses, or on the way to the doctor because there is no elevator in the building.

Paramedics have to overcome this type of obstacles on a daily basis. Therefore, slipped disks are not uncommon and frequently such physical strains lead to permanent damage to health.

With the help of the stair climber s-max, one person alone is capable of transporting a patient comfortably upstairs and downstairs. It makes no difference whether the stairs are inside or outside because the s-max can be used almost everywhere. In addition, stair coverings are not damaged.

When transported in a vehicle, the s-max 160 can stay attached to the ALS 300 of the company Utila, as well as the Dlouhy Ecocraft light. Both combinations are tested (crash test) and approved by the TÜV Rhineland according to EN 1789:2007+A2:2014.
