Cranes

Tender description

Belfast Harbour Commissioners (‘BHC’) wishes to purchase a new 4 rope harbour mobile crane to be used in the unloading of grains, animal feedstuffs, coal, stone and other dry bulk materials from ocean going vessels into rail mounted hoppers or directly onto the quay. The crane must derive its electrical energy from a diesel driven generator incorporated in the machinery house at Belfast Harbour Estate. Provision should also be made for the crane to be supplied electrical energy from a high voltage supply for both 6,6kV or 11kV at 50Hz. (The existing supply on the quays is 6,6kV, but to allow for future upgrade the high voltage connection should allow an 11kV connection with no upgrade to hardware). The crane should also be equipped with an auxiliary power supply on cable reel connection to allow plant (in most cases, a hopper) to be powered from the crane during operations. The crane will have an outreach of at least 12 metres to 44 metres and will have a heavy lifting capacity of at least 100 tons. During normal grab operations, the crane should have a lift capacity of at least 40 tons (including the grab weight) at 32 metres. The crane will be required to operate on various quays and other locations in the Belfast Harbour Estate and must be capable of travelling on the roads around the Belfast Harbour site. The maximum load per wheel must not be more than 15 tons per wheel with an outrigger loading no greater than 130 kN/m2. Attention is drawn to the need to provide an efficient means of lowering the jib and allowing the crane to travel with the jib in the lowered position if it becomes necessary to negotiate height restrictions. The crane shall have a diesel fuel tank not less than 6 000 litres capacity and have a fuel consumption of not more than 50 litres per hour. It must also be capable of being refuelled from the ground. The crane shall be capable of being programmed for different loading and luffing configurations as may be required for different quay loadings on different quays. Bidders should note that, in relation to the duration of the contract, there is an option for a 25 year maintenance and servicing contract with the successful bidder, but this is an option only at this stage. BHC may, but gives no commitment that it shall, purchase parts, spares packages, support and/or servicing from the successful bidder during this period. BHC is seeking the shortest overall delivery programme (subject to BHC being reasonably satisfied that the delivery programme is achievable) and for operational reasons, BHC's preference is a maximum lead time for delivery and commissioning of the crane of three (3) months from order confirmation by BHC. Further details of BHC's required delivery and handover requirements will be provided at the invitation to negotiate stage of this process. Both within and outside the warranty period, anticipated to be a minimum of two (2) years from handover, BHC must be able to call upon the successful bidder to attend the harbour to provide on-site technical assistance within the next working day following such a request. Further details are available in the Pre-Qualification Questionnaire (‘PQQ’) available on request from the contact point referred to above.
