Crane blocks require frequent inspections daily, periodic inspections quarterly to annually depending on use, and a complete disassembly and thorough inspection service every 5 years. Our service technicians started with a complete inspection of the duplex hook and attachments checking for deformation, cracks, gouges, and thread wear.  They then checked the latches on either side of the hook for proper function. The sheave wheels were inspected for misalignment, or wobble, and wear, and the proper positioning of sheave pin nuts. The rope grooves were checked for normal wear from use or for abnormal wear from misuse such as using improperly sized wire rope. This block is designed to be used with 2-3/4" diameter wire rope. All nuts, bolts, pins, and other hardware were double checked to make sure they were still installed and that they didn't show any signs of bending. The side plates, pins and axles, fittings and trunions were checked for signs of cracking and deformation. The block assembly was completely disassembled and any damaged or missing parts were repaired or replaced.   The refurbishing process included:  - Pre and Post Non-destructive testing (NDT) - Blasting to remove all old paint - All bearings and seals were replaced with new - DNV witnessed, 110% overload pull tested (986,000 lbs.) - Re-painted and tagged - Full certification pack ### BEFORE ### ![Before Image of Blocks Needing Repair](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/5.jpg?width=640&height=480&name=5.jpg) ### AFTER ### ![block repaired and being tested](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1257107.jpg?width=723&name=P1257107.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1137091.jpg?width=4032&height=3024&name=P1137091.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1197100.jpg?width=4032&height=3024&name=P1197100.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1197098.jpg?width=4032&height=3024&name=P1197098.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1197095.jpg?width=4032&height=3024&name=P1197095.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1137093.jpg?width=4032&height=3024&name=P1137093.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1257105.jpg?width=4032&height=3024&name=P1257105.jpg) - ![](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/Imported_Blog_Media/P1137090.jpg?width=4032&height=3024&name=P1137090.jpg) 1.   2.   3.   4.   5.   6.   7.   8.                   Comments for this post are closed. #### Categories - [News](https://lifting-20560760.hs-sites.com/news/tag/news) - [Newsletter](https://lifting-20560760.hs-sites.com/news/tag/newsletter) - [Press Releases](https://lifting-20560760.hs-sites.com/news/tag/press-releases) - [Product Spotlight](https://lifting-20560760.hs-sites.com/news/tag/product-spotlight) - [SBP Holdings News](https://lifting-20560760.hs-sites.com/news/tag/sbp-holdings-news) - [Videos](https://lifting-20560760.hs-sites.com/news/tag/videos) #### Latest News - [Bishop Lifting Acquires Worswick Group Holdings & Expands into Florida](https://lifting-20560760.hs-sites.com/news/bishop-lifting-acquires-worswick-group-holdings) - [Bishop Lifting Acquires Westech Rigging Supply & Expands to Northwest](https://lifting-20560760.hs-sites.com/news/bishop-lifting-products-acquires-westech-rigging-supply) - [Bishop Lifting Acquires Silver State, Expands Reach into Nevada](https://lifting-20560760.hs-sites.com/news/bishop-lifting-products-acquires-silver-state) - [Bishop Lifting Acquires All-Lifts, Inc. and Expands into the Northeast](https://lifting-20560760.hs-sites.com/news/bishop-lifting-products-acquires-all-lifts-inc.-and-expands-their-reach-into-the-northeast) - [Altamont Capital Partners Acquires Bishop Lifting from SBP Holdings](https://lifting-20560760.hs-sites.com/news/altamont-capital-partners-acquires-bishop-lifting-products-inc.-from-sbp-holdings) [![BishopLifting_WebTemplates_082522-04](https://lifting-20560760.hs-sites.com/hs-fs/hubfs/BishopLiftingProducts_October2022/Images/BishopLifting_WebTemplates_082522-04.png?width=183&height=53&name=BishopLifting_WebTemplates_082522-04.png) ](https://lifting-20560760.hs-sites.com) **Get a Quote** We understand that there are many factors that go into choosing the correct sling, wire rope, rigging hardware, or lifting device for a lift.
