4. Pre-lubricated, replacable type bearing bushes are standard features. Fe510 steel or equivalent is used for the precision ground axles and cylinder bolts. For heavy duty work we recommend chrome plating heavy wear parts, including grease points or grease free spherical plain bearings with seals.
For lifts working multi-shifts, in foundries or under other exeptional conditions we usually recommend sealed, spherical bearings all over. Our technicians are always willing to discuss solutions with our clients.
5. The 1,400 rpm power packs are selected for their exceptional reliability and low noise (<70dBA). A built in high pressure filter helps protect the lowering valve from malfunction. The lowering speed is adjustable on site and is controlled by a pressure compensating valve. Mains supply 400V, 3 phase, 50Hz; control circuits 24V. Each lift is protected to IP54 and is ready to use when connected to a mains supply and suitably installed. The control station is on 3 metres of flexible cable complete with Emergency Stop and deadman (constant pressure) UP and DOWN push buttons.
