Folding Power Wheelchairs - YATTLL
Folding power wheelchairs are designed to liberate pysical, it is suitable for all day use while at the same time offer some portability. The frame of the folding power wheelchair is basically the same as the frame of a traditional folding manual wheelchair frame.
Folding power wheelchairs usually are available with all the configuration options and are suitable for the many different types of seating systems available for manual folding wheelchairs, except a few structures.
To fold these electric wheelchairs, it must remove the battery pack and seating products from the wheelchair. It can be folded from side to side just like a manual wheelchair. The power wheelchair is heavier than a manual wheelchair because of the joystick, electronic control box and motors will still be attached to the frame.
Batteries and Performance
Because these power wheelchairs are intended to be folded and and lifted for transporting, the batteries are generally as small as practicable but there will be two of them which deliver each 12 volts and are wired together in series to provide 24 volts to the motors and controllers. The batteries of these power wheelchairs always use lithium or lead acid battery.
The power wheelchairs of this category will provide anywhere from 30 to 40 on a full battery charge. The range indicated on any power wheelchair will be the "best case" scenario and can not usually be expected with normal use.
The speed of these smaller sized(12.5" & 8") wheels are lower than what can be expected with full sized power wheelchairs and range from 4 km/h to 6 km/h. Besides, this specification will be affected by user weight, terrain, slope and battery condition.
The seats for folding power wheelchairs are the same as manual wheelchairs and come in sizes between 14" and 24" wide by 16" or 18" deep depending on the model however added or reduced seat depth can be attained by how the wheelchair seating is set up.
Frames and Weights
The frame of these power wheelchairs can be steel or aluminum alloy and has a crossframe connecting the two sides together that allow the wheelchair to fold. The wheels, motors and electronics will also remain attached to the frame. Weight capacities for folding power wheelchairs are usually reach to 140kg.
The turning radius is the amount of free space required in each direction around the power wheelchair when turning a complete circle. The radius is one half of the diameter of the total circle. The smaller the turning radius, the more manoeuvrable the power wheelchair will be indoors. The range for the turning radius for this type of power wheelchair will be between 30" and 36".
The rear wheels are normally 12" in diameter and have either solid rubber and the front casters will likely be 8" in diameter with solid tires. The use of these smaller wheel sizes will help reduce the size and weight of these wheelchairs and aid maneuverability.
