It is reported that Konecranes UK’s Industrial Crane Division in East Kilbride is to supply Corus in Scunthorpe and the Parker Steel Group in Shoreham with cranes fitted with magnetic equipment for steel handling.
At Corus's Long Products base in Scunthorpe Konecranes is to supply a 25t LV crane and a 10t SM Semi Goliath both of which will be fitted with Corus’s own supplied magnet equipment. The contract worth GBP 477,000 will be delivered in December 2010.
The 25t LV crane spanning 39 meters will have a single hoist trolley with two hooks spaced at 4 meters. The trolley comprises a base frame and a top frame that has partial rotation ability for load alignment purposes.
The SM Semi Goliath will operate on a 15 meters span. Both cranes will be fitted with inverter variable speed devices on cross and long travel motions as well as closed loop inverter variable speed control on the hoist.
Other features include radio control and a performance condition monitoring control unit that can extend the crane’s life, enhance it performance and safety and ensure that maintenance requirements are scheduled to suit actual usage, and unscheduled shutdowns are avoided.
At the Parker Steel Group’s steel stock yard near Brighton, Konecranes will supply a 16 tonnes SMTD crane operating on a 36 meters span and fitted with two 8 tonnes SMT trolleys. All magnet equipment is being supplied by Konecranes. This order will be supplied in February 2011.
The SMT stands for SMARTON, which has an intelligent, yet easy to use Human Interface to Machine system keeping the user continuously up to date on not only the weight of the load but also its position relative to the available workspace. In addition, the crane monitors its own condition and recommends when and what kinds of inspection or preventive maintenance should be performed. This way, the customer can better plan and minimize maintenance shutdowns, thereby maximizing uptime and saving costs.
The design is based on improvements in crane technology in modular components and features. This means that the crane can easily be updated with smart solutions, such as automated positioning, sway prevention, extended speed range, defined working areas, maintenance monitoring or remote diagnostics, to meet evolving changes in a customer’s business and process needs.
This SMT crane will also have Konecranes' closed loop inverter variable speed control systems, radio control with a spare transmitter, anti collision between this crane and an existing crane, anti collision on the trolleys, true vertical lift with anti-sway features to ensure load stability.
The magnet equipment includes quick release mechanisms allowing different magnets to be interchanged quickly to suit different load types. Each individual magnet can rotate 90 degree to suit load widths. The crane can also be used as a normal hook crane. Because the crane and magnet equipment will be operating in the open air close to the sea, the crane control panels and junction boxes will be stainless steel and the crane and magnets will be painted with a special marine environment paint treatment.
