May 19 - Doosan Heavy Industries & Construction has used its Manitowoc MLC650 crawler crane to carry out heavy lift operations at a congested railway station site in Daegu City, South Korea.
Due to the site's limited land area, it offered little space for large cranes to operate, so the compact MLC650 crawler was put to use lifting pre-cast concrete sections, weighing up to 55 tonnes each, into position.
According to Manitowoc, the crane was ideal for the job due to its ability to navigate in the highly congested jobsite and its increased capacity for heavy lifts without traditional counterweight configurations using its variable position counterweight (VPC) technology.
For the railway station project, the MLC650 was configured using a 68 m main boom with the VPC-MAX attachment. In this set-up, the crane was used to service a load of 62 tonnes, positioning it at a radius of 50 m.
Following the completion of lifting operations at the Daegu site, the MLC650 was immediately moved to a cement factory, where it will support the removal and replacement of equipment for a refurbishment project.
