Caterwil GTS4 WD special features

All-terrain electric wheelchair GTS 4WD is a reliable device to use in any circumstances - indoors, in the inaccessible city streets, on the rough terrains. The device has combined all the best qualities: it’s compact, easy to operate, has great off-road performance and able to climb the stairs. The Caterwil GTS 4WD is an all-wheel-drive version of the stair climbing Caterwil electric wheelchairs. It has 4 drive wheels and a crawler drive for climbing steps. The all-four-wheel drive makes possible to turn around in the limited space. It can be easily navigated on any type of surfaces. Another advantage is its compact size: it’s 67 cm wide and 86 cm long (without footrests). The full length with the footrests will be 105 cm. The weight of the all-terrain wheelchair is only 98 kg!

General information

The innovative combination of the wheel drive and the track drive helps the owner of the device to be as much autonomous as possible. The wheel mode provides comfortable road navigation; the tracks system is suitable for climbing the stairs or any other obstacles. The pneumatic wheels allow to use the wheelchair in the mild off-road conditions and to overcome thresholds up to 5 cm. This model will suit people of all ages with spinal cord injuries, cerebral palsy, lower limb injuries and other musculoskeletal disorders. It is also suitable for people in rehabilitation after stroke or chemotherapy; patients with diabetes, cancer; people with a complex hip prosthetic; and the elderly. Comfort In all the Caterwil’s wheelchairs in the GTS series the user can do the following options: Adjust the backrest up to 180 degrees. Change the tilt angle for the footrest. The wheelchair can be turned into bed when the backrest is fully rested and the footrests are up to max. Manage the height of headrest, armrests and footsteps. Adjust the sensitivity of the joystick. Manage from the remote control the tilt angle of the seat relative to the horizon.


  Built-in gyroscope system provides the horizontal position of user in the process of climbing, automatically calculating the correct position for the chair depends on the stairs angle at the same time. The unique 4-tracks system guarantees an excellent grip with the stairs, even if they have rounded or damaged edges. Based on that, the wheelchair can’t self-arbitrary fall downstairs. The GTS 4WD has a programmed mechanism for stabilizing the wheelchair in case of extreme tilting. If the user chooses potentially dangerous action, the system will be blocked automatically. Brake system and Power failure The GTS5 has a safety system to protect the user in case of accidental or intentional power failure. The device has electromagnetic brakes that will block the movement if the power runs off. In such cases, it can be navigated with the assistant handles like a regular wheelchair.

Safety belts

The wheelchair can be ensured with 2- or 4-point safety belts as an optional feature. Transportation The height in transportation mode is only 70 cm. The seat can be folded, this way the wheelchair can be transported in the vehicles with large cargo areas. The Caterwil 4WD allows travelling by planes and by trains. The GTS 4WD motors can be shut off by turning the switches under the seat by 90 degrees and then simply wheel it.
