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.
In addition to inheriting a 12-year-old 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.
The recent installation of the cranes at Harcliff Mining Services was conducted over a weekend in order to be COVID-19 compliant in terms of meeting the various protocols such as social distancing and working in a clean and sanitized environment.
EKKE Single Girder Crane
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.
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 double-girder crane can transport heavier unit loads than a crane which has a box-section girder – without exerting a higher load on the crane runway and building superstructure, which enables existing buildings to be utilised even better. The cost benefits that can be achieved for new buildings are due to the use of optimised supports and foundations.
