Hoists used in observation wheel.

Three J D NEUHAUS air operated hoists, each providing a 50 tonne lifting capacity have been utilised in the construction of the world's largest observation wheel located at The Linq, Caesars Entertainment's $550 million outdoor retail, dining and entertainment district located in the heart of the Las Vegas Strip. The wheel, which tops out at a height of 550 feet, provides an impressive view for both day time and night time skylines of this unique resort destination. The structure, known as the Las Vegas High Roller, comprises 28 viewing cabins with a total 1,120 passenger capacity. The impressive height exceeds other Great Wheels of the world such as the Singapore Flyer at 541 feet (28 cabins with 784 passenger capacity) and the UK's London Eye at 443 feet (32 cabins with 800 passenger capacity).

The air operated hoists were located at a temporary chain fall platform suspended below the wheel central hub, and utilised their 280ft of cable fall to lift equipment from the ground level. These lifts included 18 temporary radial struts, each being 40 tons in weight, together with transfer trusses of similar weights and all the individual outer rim segments of the completed wheel, together with a total of 112 cable locking assemblies initially assembled at 50 % tension loads. The temporary radial struts were installed to provide the accurate spacing of the individual wheel rim segments from the central hub unit during initial build assembly. These were then sequentially replaced by the cable locking assemblies, which when fully tensioned provided the radial spokes of the completed wheel assembly.
