Wheelchair : Handicap Products: Wheelchair Safety With Power Wheelchairs - 0 views

  •  
    Folding Lightweight Wheelchairs For indoor wheelchair safety the folding power wheelchair models that are lightweight have front casters which turn easily, making them ideal for use in small apartments. Having the casters in front makes this a dangerous chair to use outdoors as the front wheels can turn sharply if encountering a crack in the sidewalk, incline, or rocks.Wheelchair india is manufacturer, supplier, distributor and dealer of Karma KP 10-2 Power Wheelchair for disabled and handicapped in india. They usually have one or two removable batteries and have a similar appearance as the manual wheelchair. They can be controlled with a joystick or a sip and puff method. Lightweight Power Assisted Wheelchairs These chairs can be propelled in a similar manner as the manual wheelchair or use a battery. You may want this type if you want to keep fit and get some exercise but need some power when going up an incline or when traveling a distance. They are smaller and lighter weight than the folding wheelchair and have smaller batteries and motors. Dual Purpose Power Wheelchairs These chairs generally are good for either indoor or outdoor use. You need to have larger wheels in front for outdoors as this is a safety feature. It is better to have six wheels for stability when traveling outdoors. These indoor/outdoor power chairs compromise wheelchair safety and perform poorly when you do not have enough room to turn indoors and you need to travel over rough ground and uneven surfaces. Their optimum performance indoors is when you have wider doors and hallways in assisted living facilities, nursing homes, or homes/apartments. Ideal outdoor surfaces in urban and suburban areas would include sidewalks and paved areas. Outdoor Power Wheelchairs These chairs weigh as much as 400-500 pounds, add the weight of the user up to 250 pounds and the total weight is approximately 650 pounds. They are very efficient outdoors with their rear wheels they can sa

Wheelchair : Handicap Products: The Rigid Versus the Folding Wheelchair - 1 views

  •  
    Manual wheelchair has two types: one with a collapsible frame and the other with a frame that is rigid. The one with a collapsible frame is called the folding wheelchair and it is easier to transport and store than the rigid-framed wheelchair. Because it has reinforcing struts as well as folding and locking mechanisms, the first is relatively heavier than the second. A car can be used to transport a folding wheelchair. It can be placed in the car's trunk instead of having to provide for special moving arrangements or use a bigger vehicle such as a van. The wheelchair that folds usually has an x-frame that makes it possible to fold it sideways. When not in use, it can be kept in a small area of space. When navigating on an uneven surface, the four wheels of the folding wheelchair remain on the ground because its flexible frame of the chair yields and bends to make up for the unevenness of the terrain. This makes it more stable on the uneven surface than the rigid framed chair. On the other hand, it is less stable on a hard floor surface. While making it easy to fold and transport the chair, the parts of the folding chair that can be removed and adjusted can get lost or worn down more easily. The requirement for more frequent repair and replacement of these parts makes the chair that can be folded more expensive to maintain. The wheelchair with a rigid frame can be kept in good condition more economically. The moving parts of the folding wheelchair make the chair's frame more flexible. This flexibility absorbs a significant portion of the force exerted to propel the chair. Thus, it is harder to control and push. Its relatively heavier weight adds to this difficulty, requiring more effort, as well as greater strength and dexterity, to propel and maneuver the wheelchair when compared to the rigid wheelchair. There are certain activities that are not appropriate for the user of a chair that can be folded to engage in. The desirable features of the folding

What Is a Flanged Gasket ? Everything Explained. - 0 views

  •  
    Before we talk about Flange Gasket, let's understand what a gasket is. Here, I would like to go with a universal definition. "A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression." Yes, that was the definition given in Wikipedia. Well, that definition covers a lot of details about gaskets. If you are someone who works in the mechanical industry, then you know all of it. Have you heard of "less-than-perfect" mating surfaces? When you want to fix two less-than-perfect surfaces such as two pipelines, then you will need something to fill that less-than-perfect gap. The piece we used for sealing that gap is called a gasket.
