South Korea’s Bong-Hwang adds Grove GMK5250XL-1 and gets to work on factory-build

  • South Korean contractor purchases a GMK5250XL-1 and sends it immediately to support the construction of a new factory. 
  • The company specializes in building factories for electronics and chemical businesses in the Eumseong region of the country.
  • The crane’s combination of long boom, compact dimensions, and superb maneuverability ideally suits the narrow, cramped roads of the local industrial estates.

South Korean contractor Bong-Hwang received its Grove GMK5250XL-1 all-terrain crane, following a handover ceremony at the Manitowoc factory in Wilhelmshaven, Germany earlier this year. The 250 t capacity crane was purchased with several optional features, including a 17.8 m bi-fold swingaway jib, self-rigging auxiliary hoist, and a boom removal kit.

The new crane has been dispatched to its first job, installing 3 t precast concrete slabs at a new chemical plant for industrial giant Han-Hwa in Eumseong, about 100 km southeast of Seoul. Bong-Hwang was quick to recognize the advantages of the five-axle crane on this project, with the longest boom in its class at 78.5 m and a compact footprint. 

“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,” explains Lee Guan-Hwi, CEO of Bong-Hwang. “The maneuverability offered by the 10x6x10 MEGATRAK® running gear, and the short, 5.2 m tailswing lends itself to maneuvering around these tight industrial jobsites, even with a full counterweight of 80 t.” 

“Removing the need to repeatedly install or remove counterweight saves us a lot of valuable time too. And the choice of five outrigger positions makes setup in tight spaces quicker and easier. Working at a 30 m radius, we extend the boom to 70 m, and the 3 t concrete slabs can be easily handled.”

The GMK5250XL-1 joins a GMK5120L in the Bong-Hwang fleet. Bong-Hwang was established in 2012 and focuses on factory building and renovation projects. The Eumseong area is 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,” concluded 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. We now know it is tough enough to handle anything we can throw at it.”
