(RSS) has supplied four 25t capacity JD Neuhaus (JDN) Profi air hoists for a major infrastructure project in London. RSS delivered the hoists, with 8m height of lift, through its nationwide (UK) distributor and service partnership with the German manufacturer. They will be used simultaneously to lift loads over a two- week period; RSS does not anticipate a requirement to deliver any after-sales or onsite support during that time. Steve Hutin, managing director at RSS, says: “We have only been working with JDN since mid-2019 – offering pneumatic and hydraulic hoists, crane systems, and components – so to already be receiving repeat orders from the highest profile projects around, says a lot about the momentum we’ve gained and the reputation we’re building for being able to deliver these hoists in addition to the lifting and rigging gear for which we might be better known.” Explosion-protected series RSS did not provide additional rigging gear on this occasion and there was no requirement to make adjustments to chain lengths, as was the case in an earlier case study involving two 50t capacity air hoists. Nor was it involved in lift planning. The Profi air hoist range, offering air pressure in 4 to 6 bar, is an explosion-protected series, suited to heavy-duty industrial use. It RSS supplies JDN air hoists for infrastructure project RSS delivered four 25t capacity JDN Profi air hoists to a major infrastructure project in London. Each hoist offers 8m height of lift.
