Precautions for lifting at the extrusion granulator maintenance site
Thread Content
For planned maintenance of polyolefin extrusion granulators on-site, a thorough lifting plan is required. The challenges include the offset between the lifting equipment and the center of gravity of the extruder, the use only of manual winches for lifting the equipment, and insufficient height available in some factory areas for lifting purposes. The necessary tasks include: 1. Proper qualification certificates for lifting operators; qualified personnel for maintenance work, including crane supervisors and riggers. 2. Conduct a thorough on-site assessment: during the on-site inspection, evaluate factors such as the equipment’s weight, center of gravity, lifting points, and lifting equipment, based on both documentation and on-site experience. 3. Routine maintenance of lifting equipment is necessary before scheduled shutdown for repairs. 4. Lifting tools provided by the manufacturer. For example: the 8-shaped sling for the screw. 5. Design and manufacture specialized lifting equipment based on the space and lifting points. The legend shows the solution adopted for the main reduction gear cover of the JSW Nippon Steel extrusion granulator when there was insufficient space on site. Of course, the necessary tools, plans, and even obtaining professional qualification certificates are all based on solid on-site experience. Sufficient patience and seamless cooperation from the on-site team are essential guarantees for implementation. #Coperion #Coperion #Kobe Steel #Kobe Steel #JSW #Flender Polypropylene
When carrying out on-site maintenance and lifting operations for polyolefin extrusion granulators, the following points should be noted: 1. Ensure that all operators possess the appropriate qualification certificates, including those for crane operation and rigging. 2. Before starting the lifting operation, a comprehensive assessment of the equipment’s weight, center of gravity, lifting points, and the lifting equipment itself must be carried out to ensure safety. 3. Carry out proper maintenance of the lifting equipment to ensure its safe and reliable use during periods of inactivity. 4. Use specialized lifting tools provided by the manufacturer, such as figure-8 slings, to enhance the stability and safety of lifting. 5. Design and manufacture specialized lifting equipment suitable for the on-site space constraints and the specific requirements of the lifting points. Furthermore, the on-site team should possess sufficient patience and strong teamwork skills, which are key to ensuring the smooth progress of lifting operations. .

The Kollmorgen JSW has a similar structure. All brands are available in the photos.
