Cementing the benefits of specialist services
Published: 01 September, 2022
The varied and specialist services available from HOIST & WINCH have come to the rescue of a cement industry customer that was looking to replace a large rotor used in its production process. Thanks to the design, manufacturing, test, certification and installation services offered by Hoist & Winch, the cement works was able to avoid the long lead times associated with buying original OEM equipment, and successfully complete a highly complex and challenging lifting operation.
In essence, the objective was to lift and replace a large rotor fitted with pivot-mounted hammers that break down the media as part of the cement manufacturing process. Located at the base of a very large production enclosure, a pair of bearing journals provides support for each end of the rotor. Hoist & Winch had to design and arrange manufacture of equipment that would help to lift the worn and replacement rotors in and out of position in a precise manner without damaging any adjacent equipment, including the main drive motor and gearbox.
The cement works last performed this particular maintenance lift to replace a worn rotor in 2010 using a pair of lifting lugs that had since been disposed of. New replacement lugs were only available from the original supplier of the cement production process equipment on a very long lead time, which did not meet the requirements of the customer’s programme.
With a total design weight of 80T, rotor lifting was courtesy of a pair of tandem-controlled 41T SWL (safe working load) wire rope hoists located on monorail beams arranged at 90° to the rotor bearing journal stub shafts.
