J D Neuhaus offers a BOP handling system comprised of twin air-operated monorail hoists with a joint lifting capacity of 200 tons. These hoists are a special compact design developed to suit on-site operational requirements, and each hoist represents a 45% reduction in the horizontal profile length compared to the standard product.
These hoists run in parallel on two overhead beams in excess of 72 ft in length. Each hoist is also fitted with a copper-coated bottom block and clevis (providing increased spark protection), together with a galvanized chain box. The overhead support beams incorporate a rack and pinion drive for the trolleys, ensuring that even inclines up to 2.5° can be negotiated. The total traverse distance is in excess of 60 ft, while the lift height available is 50 ft.
Both hoists incorporate overload protection, with limit switches also provided for the hoist and traverse operations.
