Sling Service Center
A very special
kind of service ...
... that combines the convenience of a distributor based repair service with the dependability and expertise of real factory service. Up to now, it has been difficult to bring you both. For your chain distributor to offer you the kind of chain sling inspection and repair service required by OSHA and other regulatory bodies, it would be necessary for him to duplicate a chain plant at a cost amounting to hundreds of thousands of dollars. Any makeshift method of doing this important job could be dangerous and costly to his customers.
We do a little bit of everything at our Chain Sling Service Centers.We have to if we're to give you the kind of service you need. (Government standards are tougher than ever ... and down-time is more expensive than ever!)
We've designed our Service Centers to be complete sling manufacturing facilities. Here you will find the capability to fill almost any specification on short notice, plus a complete repair service including heat treating, proof testing, inspecting, and recertifying. In addition, our sling service centers provide items not listed in any catalog, to meet your special sling needs, chains sizes 9/32" thru 2" Some of these special design capabilities include:
| "S" Hooks | Plate Hooks |
| "J" Hooks | Lifting Tongs |
| Mold Hooks | Pallet Lifting |
| Core Hooks | Assemblies |
| Die Hooks | Die Pins |
| Lifting | Slab Lifting |
| Shackles | Chains |
| Box Hooks | Mine Roof Plates |
| Master Links | Door Lifting |
| Crane Links | Chain |
Inspection
Every master link, chain link and hook is checked for excess wear, nicks, gouges, deformation and stretch. Components needing replacement are marked and sent to the appropriate department for repair. Each chain sling goes through eight or more inspections before it is returned to you.
Repairing
The repair section removes worn, damaged, stretched or deformed chain sling components and replaces them. All repair materials used are, of course, of original manufacture specifications.
Heat Treating
The chain sling is again inspected after all repairs are made and before it is sent on to heat treating. Huge heat treating furnaces are available at each Acco factory repair center. They are designed to accommodate slings of every size. Carefully controlled heating, quenching and tempering produces slings having the same high tensile strength as the original.
Proof Testing
All attachments and chain - the complete chain sling assembly is placed on hydraulic proof testing equipment. Here a load is gradually applied under direct tension, over the chain sling's full length until the proof load, in pounds, is reached. After proof testing, the sling is again thoroughly inspected.
Recertifying
Each chain that has been reconditioned at a factory chain sling service center is restored to its original condition and recertified. The metal tag that identifies each chain sling is restamped with the sling's rated working load limit, chain size, reach and grade. In short order, the chain sling is returned to you complete with a signed test certificate attesting that the sling has been proof tested and meets its original standards.
