Ketten Wälder GmbH, established in 1948, set-up cromox®, a premium stainless-steel brand, approximately 17 years ago. The cromox® range includes chains, chain slings, load hooks, shackles, chain hoists, and hoist trolleys. The CRSV line is used for connecting synthetic slings by means of an optimised load-bearing surface to an oblong-shaped masterlink sub-assembly – likely a lifting point or machined attachment on a load.
Three new sling connector models are available: CRSV-08, CRSV-10, and CRSV-13, in 1.55t, 2.45t, and 3.85t capacities. Users can rig 30mm-, 40mm-, and 50mm-wide synthetic slings. The range is an evolution of the popular cromox® CVG series of connecting links. The new line will be of interest to the multitude of existing and prospective customers that supply equipment for applications involving roundslings and masterlinks.
Stainless steel sling connectors (Grade 60) – built for demanding environments
Franz Wälder, CEO at Ketten Wälder GmbH, said: “Synthetic rigging equipment and roundslings are ubiquitous in many industries where specialised lifting attachments are a prerequisite. The defence sector is just one example, where critical components, like propulsion systems, need to be lifted on vehicle, vessel, and weapon system production lines. The CRSV presents a number of natural product advantages – Grade 60 and AISI Duplex material – that suits it directly to cleanroom and demanding environments.”
High-strength, corrosion-resistant, and cleanroom-ready
A typical sling assembly would utilise anything from one to eight CRSV products, rigged the same way as a chain sling with a hammerlock (a mechanical coupling used to connect two components of a lifting or load-handling system). End users make their selection based on the working load limit (WLL) and dimensional charts provided.
Grade 60 offers higher WLL at a smaller dimension and lighter weight. AISI 318LN Duplex body and bolt combine with AISI 301 spring. AISI 318LN has a high ductility strength and superior corrosion resistance.
Wälder added: “While we acknowledge that geo-economic challenges are out there, our concentrated niche approach to markets, aligned with steady development and ongoing investment, continue to put us in a position where we can successfully service our ever-growing customer base. These new cromox®-branded roundsling connectors are another example of that.”
LiftEx 2025: Sling connector launch at Europe’s top lifting event
See the new cromox®-branded CRSV roundsling connectors at this year’s Lifting Equipment Engineers Association (LEEA)-organised LiftEx trade show, which takes place 18-19 November at the Exhibition Centre Liverpool.
In the meantime, Ketten Wälder GmbH will boost stock across three global warehouses: in Germany, the UK, and the U.S., and is already shipping directly from headquarters.
