CRANE AGENT WINS CONDRA ORDERS
North Coast Cranes & Lifting , the Richards Bay-based lifting equipment company , has won separate orders for Condra cranes to be installed in a chemical element refinery furnace and on a mining dredge .
An order for two further machines is expected .
North Coast Cranes is Condra ’ s Northern KwaZulu-Natal agent , with a mandate to install and commission machines as they arrive from the main Johannesburg factory , and provide scheduled maintenance and on-call service support . Annual load tests and the quarterly sling inspections required by law are also carried out .
The agent has a very strong customer focus , concentrating on service and maintenance capability rather than equipment sales . All brands of lifting equipment are supported , but orders for complete cranes are usually met by Condra .
