the wasted cost as a result of extended time peri- ods, more exact planning, setup and commissioning resource allocation can be done when the substa- tion and equipment is at our factory,” he says. “For our Malaysia project, for example, we had two load sharing conveyor drives connected via a 2 km fibre link and we never had to send the VSD specialist to site. We did all the setup and test- ing here in Johannesburg and performed the hot commissioning via remote link. Commissioning time was reduced to two days setup and testing in Johannesburg and less than a day of hot commis- sioning on the VSDs via remote connection. Imagine if we had to fly the specialist to Malaysia, then we would be looking at a week, at least,” adds Joubert. Additional solutions Additionally, Hamar Controls offers skid-mounted solutions for applications where substations or electromechanical plants need to be moved to new locations from time to time. Examples where skid-mounted solutions can be applied include mobile transformers, mobile pumps, extendable or shiftable conveyors, semi-stationary stackers, sand and slurry mining operations and many other applications where plants are of a semi- permanent nature.

“Skids are built in such a way that they can be moved by crane, front-end loader, tractor or winch. The skid can be designed to suit the customer’s available method of moving it. Like the other mobile solutions, skids are manufactured and factory tested before shipping to site. If transportation is a chal- lenge, the skids can be built and factory tested and then disassembled before transportation. Because skids are pre-assembled, they can easily be re- assembled on site by the client or by Hamar Controls personnel,” concludes Joubert. 
