Main construction specifications

- Traction head
• shaft mounted gearbox combined to an endless thread shaft, with reverse turning block, oil bath lubrication, directly coupled to the head pulley shaft.
• head pulley, barrel profile and rubber lined (diamond lagging), assembled on bearings lodged into oversized berings housing; bloccked to the main shaft by two heavy duty shrink disks.

- Tail head and takeup
• load Hopper steelwork manufactured with 5mm thickness steel plate, integrated rubber lips, height adjustable E’ prevista su tutta la lunghezza del nastro.
• barrel machined tail pulley. Assembled on heavy duty bearings and supports, blocked to the shaft with shrink disks
• belt takeup system. The tail pulley is assembled on a sliding system drived by an endless screw and a bronze pinion with trapezoid tread (for a great resistance force without any chance of getting loose). It allow a regulation of about 300mm.

- Idler and rollers
integrating sealed for life rollers (two or three depending on the belt width), with a structure built by metal sheet supports welded on a U shaped beams.

- Rubber Belt
all resistence classes available, selecten depending on the application.

- Belt scraper
• Urethane X section scraper, with Rosta elastomer tensioning system
• Delta scraper on the tail head, specifically designe with tail pulley protection lips to avoid any rock intrusion on the ineer side of the belt
