EXPLOSION-PROOF MOTOR DRIVEN CABLE REELS MCR

Transcription

1 MCR Bull motor driven able reel is speially designed and manufatured for mobile feeding power systems. The feeding is realized by low voltage eletrial ables. The mobile systems are generally overhead ranes or translating working mahines, used in all kinds of environment, suh as ports, steelworks, onstrutions, lift and transports plants. This means that this mahine has always to be integrated with other mahines as a omplement. For this reason it is normally ontrolled by the mahine it is integrated with; rarely, it is equipped with an independent ontrol panel.

Power to the mahine must be turned off before arrying out abling. Connetions are to be made in ompliane with the wiring sheme of the ontrolled equipment. After installation has been ompleted, the prolonged ontat with oils and aids when using the equipment, as these may damage the produts. 1) Using the loknuts, attah the entral pipe to the minimum 3mm thik plate with a entral hole of ¾ Ø (using the reduing able lip on the nuts). As an alternative the entral pipean be attahed to a plate with a threaded hole of 1, 1.5mm pith using the loknuts as jam nuts 2) Rotation is ahieved thanks to 4 Ø 13mm pivots on the over at a distane of 100mm from eah other. We reommend the oupling to be made with slak to take up any possible runout during rotation. Rotation an also be ahieved by attahing the over using the 4 pivots, thus enabling the entral pipe to rotate by (thanks to a suitable oaxial joint) 3) The ables are onneted to the brushes through the pipe union on the superior flange. Please ensure that the wires do not interfere with any moving parts. The rings are onneted to the terminal board through the pipe union 4) Please hek the equipotential of any surfaes not generally reommended to be used under tension, and the ground onnetion using ables provided MAINTENANCE A program of periodial maintenane is required to be arried out to ensure that the PRP slipring is kept in perfet working order. All maintenane is to be effeted by qualified personnel using only original spare parts. In partiular: 1) Disonnet from power soure and wait until the internal parts have ooled down 2) Remove the mobile semi-overs 3) Copper-graphite brushes exeution: hek the brushes for wear and tear, and hek that they fit properly to the rings Blade brushes exeution: hek the brushes and rings for wear and tear 4) Copper-graphite brushes exeution: remove opper-graphite dust with de-humidified ompressed air or a lean brush Blade brushes exeution: remove dust or grease again with a suitable lubrifiant 5) Chek tightness of ables 6
