OVERHEAD CRANES
Demag supplies Harcliff Mining with single and double V girder cranes with supporting service agreements Harcliff Mining Services has chosen Demag Cranes to supply two 25-ton double V girder cranes and one 6.3-ton single girder crane at their newly acquired factory in Meadowdale, Germiston. The cranes have been successfully installed and are supported by Demag Service Agreements. “Harcliff Mining Services recently acquired new factory space which is to be used for their gearbox operation where their volume of production has increased. In addition to inheriting a 12-yearold Demag crane that was still working well, they required further crane equipment for this increased capacity. After meeting with our Demag specialists, it was established that with their proposed factory layout changes, one of our single girders and two of our double V girder cranes would meet their requirements satisfactorily” said Emil Berning, Managing Director. Darren Bagnall, Managing Director of Harcliff Mining Services commented “We knew how highly the Demag brand is regarded globally, and some of our sister companies have installed their equipment and found the quality and performance extremely high and reliable”, adding “so we met with Demag and discussed our requirements for our gearbox operation and accepted their proposals. Also, for performance stability, cost and safety reasons, 26

we have decided to support our new Demag cranes with the Demag Service Agreement Plan, which removes unexpected downtime and repair costs, giving us operational peace of mind”. The recent installation of the cranes at Harcliff Mining Services was conducted over a weekend to be COVID-19 compliant in terms of meeting the various protocols such as social distancing and working in a clean and sanitized environment. Operating within these restrictions threw up the challenge of ensuring that the removal of old crane equipment and the installation of the new Demag cranes was well synchronised to avoid delays, which was accomplished. EKKE Single Girder Crane The Demag Single Girder Crane offers excellent crane geometry and outstanding travel characteristics whilst reducing the load on building structures. The single-girder overhead travelling crane with solid girders comes in two variants: The EKKE overhead travelling cranes with welded box-section girders and the EPKE overhead travelling cranes with rolled profile girders. They offer a choice of controls:
Besides cable connected control pendants, the D3 generation of radio controls offers safety, reliability and convenient operation. The Demag DMR modular rope hoist, for example, is designed for crane applications, while our DC chain hoist already includes comprehensive features and good value for money, as standard. Two cranes can be controlled on one runway with a common radio control system using our Demag SafeControl system. The single girder crane meets Performance Level “C” and Category 2 requirements for safety-related control functions. The SafeControl fully monitors all crane parameters and giving maximum safety for individual applications. ZVKE Double V Girder Crane A significant feature of the V-type crane is the reduced weight of the crane girder compared with cranes that have box-section girders. This results in potential load capacity gains for overhead travelling cranes which can be equipped with rope hoists that have higher load capacities. This means that a ZVKE doublegirder crane can transport heavier unit loads than a crane which has
