From Wheelchairs to Powerchairs to giant sized California Electric Wheelchairs,Developed in response to the demand for more in terms of mobility options for elder or disabled people with higher energy efficiency, the advent of electric wheelchairs brought relief to many who have previously struggled with manual options. Since manual wheel chairs, motorised powerchairs were touted as the latest development in mobility, however despite being a huge leap from manual wheel chairs, they were not incredibly reliable. Electric wheelchairs now offer a highly reliable source of transport for those living with disability.
These electrical powerchairs are generally constructed from belts, gears or a combination of the two. All kinds of wheelchairs need to be regularly serviced and checked thoroughly for indications of wear and tear, although models which have been designed with belts will probably need servicing and checking more often than wheelchairs which have been designed to incorporate modern gears. As a side note, generally belt driven models are also quieter than gear operated chairs, but regardless of what model is decided upon by the owner, continual and regular upkeep and maintenance is absolutely essential if the wheelchair is to be kept running at its best.
In general, most electric wheelchairs are built around a stable base frame, however newer models are available which save on both energy and space and which can be conveniently folded up. Other components of typical powerchairs include the wheels, battery and control system.
Lighter materials are now being used to make electrically powered wheelchairs, making them easier to transport while still remaining highly durable. The brakes on the wheelchair are often controlled via a joystick situated on the arm rest and can hold the chair still automatically either when it is turned off or when the chair is stationary. Pneumatic or semi pneumatic wheels are built into the chair, as they are solid and are less likely to become flat. A design feature often found on these chairs is large wheels situated in the back of the chair, with smaller castor wheels at the front for ease of manoeuvrability.
U1 batteries are the type most often used to power these chairs, as they are able to power the chair much longer than many other types of battery. Generally speaking, gel, lead or acid rechargeable batteries are used, and the way in which the chair is controlled can vary from user to user. However the overall design is intended to operate the turning mechanisms, speed and brakes of the chair simultaneously.
While it is true that many electrically powered mobility chairs powered by rechargeable batteries can weigh more than a standard wheel chair, many of the design features make them highly popular with users, such as power tilt and recliner, which allows the user extra comfort and mobility.
