Condra has responded to increasing demand in the mining sector for automated lifting and handling with its first fully-automated crane, delivered to a platinum mine.
جنوب أفريقيا-based crane manufacturer Condra has introduced its new fully-automated overhead crane, and completed the first delivery of the system, to mining company Lonmin.
Fully-automated cranes follow a general trend away from manual control in the industrial and mining sectors, said Condra.
The company has installed increasingly sophisticated semi-automated installations in recent years, starting in 2003 with a grabbing crane installed at a Durban spice company facility for picking spices and transporting them to specific points for release over the hoppers that service blending and packing operations.
Condra recently installed the fullyautomated crane at Lonmin’s Marikana platinum mine. The crane is a 16t-capacity, 16m-span double-girder electric overhead travelling grabbing crane, featuring a customer-specified mechanical rope grab in place of a hydraulic alternative, designed to provide improved durability of mechanical operation in the abrasive operating environment of the Marikana facility.

Variable speed drives are fitted throughout the crane, delivering maximum speeds of 10m/min on the lift, 20m/min on cross-travel, and 40m/min on long-travel. Four long-travel motors enable automated control of all four wheels for precise crane positioning, accurate to within 5mm.

“This is a capability that we will offer to our customers as an option,” said Kleiner. “We will mainly but not solely target the copper mines, especially tankhouse and copperleaching applications where we have extensive experience.”
