A series of accidents involving air-powered nail guns last summer brought home the fact that the productive and powerful tools are also highly dangerous and need to be handled with respect. In the most tragic case, a framing nail punctured the heart of carpenter Camillo Juandelos on a home construction site in Ocean View, Md., in July, ending the man''s life at the age of 25. Police said Camillo''s brother Jesus was holding the gun that fired the deadly nail.According to reports in the Delaware News-Journal, the accident took place as the two men were framing new homes in a development in Ocean View. Jesus had been bending over a stud wall using the air nailer, and then straightened up and turned to call his brother. But Camillo was not on the other side of the room as robinstandbygenerator Jesus thought; he was already standing right behind his brother. Camillo made contact with the nose of the nail gun, triggering the bump-nail mechanism and taking the nail in his chest.

The use of permanent magnets instead of rotor windings makes the motor smaller and lighter than induction motors. Using magnetic-bearing technology, a 75-ton compressor weighs 265 lb--about one-fifth the weight of a conventional compressor.A variable-speed drive (VSD) is required for the motor to operate. The VSD varies the frequency between 300 and 800 Hz, which provides a compressor-speed range from 18,000 to 48,000 rpm. This avoids a gear set. The VSD is integrated into the compressor housing, avoiding long leads and allowing key electronic components to be refrigerant-cooled. The VSD also acts as a soft starter; as a result, the compressor has an extremely low startup in-rush current: less than 2 amps, compared with 500 to 600 amps for a traditional 75-ton, 460-v screw compressor with a cross-the-line starter.

Balanced braking sounds impossible when one considers a highway tractor coupled to short doubles trailers pulling a fully loaded lead trailer and an empty second trailer, mixing new tractors with older trailers, operating on wet and dry roads, or operating with robinstandbygenerator one robinstandbygenerator vehicle in the combination that has just had a brake reline, hooked to a vehicle with brakes three-quarters worn.In the USA and Canada, government bodies are responsible for conducting roadside inspections on heavy trucks. In fact, there are well over two million trucks inspected every year in the US alone. Improper brake systems are the leading candidates for placing a vehicle out of service (OOS). The leading cause of defective brakes has been brakes out of adjustment. (US federal regulations stipulate that a heavy-duty vehicle must be taken of out service if 20% of its brakes are 114 inch or more beyond the readjustment limit for push rod travel.)
