South Korean contractor Bong-Hwang has purchased a new 250-tonne mobile crane – the Grove GMK5250XL-1 – and immediately dispatched the machine to its first job.
The company, based in Eumseong, specialises in building factories for electronics and chemical businesses in the central region of the country. Acquiring the crane to expand its operational capacities in its field of specialty, the contractor sent the crane to install three-tonne precast concrete slabs at a new chemical plant for industrial giant Han-Hwa. According to CEO of Bong-Hwang, Lee Guan Hwi, the crane’s combination of long boom, compact dimensions, and “superb” manoeuvrability were ideal for the narrow, cramped roads of local industrial estates.
“Chemical plants like this one typically have very narrow roads, making a compact crane that can match or outperform larger models the only solution for this project,” he said. “The manoeuvrability offered by the 10x6x10 MegaTrak running gear, and the short, 5.2 m tailswing lends itself to manoeuvring around these tight industrial jobsites, even with a full counterweight of 80 tonnes.”
Grove’s 250-tonne mobile crane possesses a main boom length of 78.5m, with a maximum hook height of 109m reachable with the addition of jib extension combinations, providing the machine with the “longest boom on five axles”, according to the manufacturer. The crane also features a single-engine design with the latest emission levels, reducing the operating costs thanks to a 30 per cent lower diesel consumption.
The GMK5250XL-1 joins a GMK5120L in the Bong-Hwang fleet, where they will continue servicing the Eumseong area – a hub for semi-conductor manufacturing, with many of those manufacturers being important suppliers to Samsung.
“We expect our new GMK5250XL-1 will be kept incredibly busy over the next few years but we’re definitely not asking too much of it,” said Lee. “During our visit to Wilhelmshaven, we took the opportunity to tour the manufacturing facility and were struck by the incredible attention to detail that goes into the production of every machine.”
Bong-Hwang was established in 2012.
