Structural steel is the most versatile and flexible materials in the world. This steel is used in several construction projects such as bridges, skyscrapers, marine piers etc. It is available in different sizes and shapes. According to the shapes, structural steel is classified into different categories.

Transport Wheelchair Fixed Arm with Elevating Leg Rest offers a standard dual axle that provides easy transition to hemi level, and has an attractive carbon steel frame with coated chrome provides chip proof finish. This wheelchair is the ideal companion for all your getting around needs. Black nylon seating Removable and adjustable elevating restless leg Removable armrest Breaks on wheels Endurable black structure Rubber wheels (no air required) Transport Wheelchair Transport Wheelchair is designed to only be propelled by another individual and is sometimes referred to as a companion chair or rollabout chair. Transport chairs have four small wheels instead of two small and two large. They come in different widths and weight capacities and are usually the same basic frame as a standard manual wheelchair. Transport Wheelchair features a carbon steel frame with chip-resistant chrome plating. The rear handles fold down for easy storage and transportation and the nylon upholstery is durable and lightweight. The black composite wheels require virtually no maintenance and incorporate dual-sealed precision bearings. There is a seatbelt for safety and it has padded armrests. Transport wheelchairs provide many advantages: Weight: Transport Wheelchair are easy to transport because they typically weight around 15 to 20 pounds, which is much less than a manual wheelchair. Storage: They are easier to store than traditional manual and electric wheelchairs. Most are small enough to fit into the trunk of a compact car. Expense: They are less expensive than traditional and electric wheel chairs. Prices start at around $99 and can range up to $350, depending on features. Ultralight Wheelchair Ultra-Light Wheelchair has a fold-down back and swing-away footrests for easy storage and transport. Ultra-Light Wheelchair is lighter others and still has a 300 lb. weight capacity. It features comfortable padded arm rests, an adjustable seatbelt, and a

A camshaft plays like a timing device that manages the opening and closing of the ingestion and depletion valves and also fixing the valve overlap that performs at top dead center on the exhaust stroke. The shaft is built with numerous journals which ride on comportments inside the engine. It has egg-shaped lobes that stimulate the valve train, either by the moving pushrods and lifters or by pushing straight on valve stems. The camshaft is constrained to crankshaft turning by chain's timing, timing belt or timing gears, and the failures in camshaft drive can permit the valves to interact the piston crowns, that cause widespread internal destruction. The Additional Camshaft Functions: The camshafts in mature engines may also have gears automated into them that execute the distributor and the oil pump. For modern engines, the camshaft may have a situation sensor attached to the end that transfers data to the powertrain control unit to help the module right time your fuel injection pulsations and ignition. Some engines can have several camshafts, like with some overhead cam machines, mainly ones built in a "V" structure. Engines that have a desmodromic valvetrain use minimum 2 cams, as there is 1 push-open cam and 1 pull-close cam, in place of the classic push-open cam along with valve springs to pull the valve shut as the cam revolves past the lobe and back on to the circle base. The Camshaft Measurement: Entire lobe measurement, graphic presentation and lift analysis, acceleration, velocity, bump (3rd derivative) radius of curving, angle's pressure Lobe data modified and brought to zero base circle run-out Camshaft can have Angular position listings for all lobe tip angles It can be equalled measured data and design lift data profiles in numeric and graphic modes Screen graphic presents for all motion curvatures You will be accessible to printed reports of tabular data and screen graphics Compare base circle radius, run-out, and lobe tip angles to d
