SA French to supply hoists to Zambian copper mines

SA French is supplying two Saltec T1 half- ton passenger hoists to copper mines in Zambia. The two hoists will facilitate the movement of personnel, together with light tools and equipment, up the shaft headgear framework. Louw Smit, Sales Manager at SA

French, says that the order was secured as a turnkey contract which includes the supply, installation and commissioning of the two hoists at two different mines in the region. “Vertical transport solutions always need to comply with stringent safety parameters and the Saltec passenger hoists incorporate advanced security sys- tems including a speed regulator and an overspeed emergency braking system on an independent pinion,” Smit points out. These features will ensure that mine personnel are able to undertake main- tenance activities safety and efficiently, optimising the productivity on the mines. Smit says that the integral emergency brake on the Saltec hoist will bring the cabin to a gradual stop in the event of overspeed conditions during descent. The Saltec hoists will be installed to Du Plessis says Booyco Electronics’ Proximity Detection System (PDS) has built a reputation for helping mines protect their most important asset: their people. “The PDS is designed to allow for inter- vention where a potentially dangerous situation exists between a pedestrian and a machine,” he says. “Consisting of a sens- ing device that detects the presence of an object in a working area, the system can provide an audible and visual alarm to both the equipment operator and pedestrians as they enter danger zones.” He adds that warning zones can be specified to suit the requirements of spe- cific mine areas, and standardised to a

reach a maximum height of 72 m and will be programmed to stop at five different levels on the headgear frame. Manufactured by Torgar, Saltec passen- ger and material hoists feature rack and pinion drives ensuring reliable operation. This type of system also requires minimum maintenance and is considered the safest for vertical travel. Constructed as a heavy duty elevator which is engineered to operate under the worst conditions, the Saltec hoist is manu- factured from hot dipped galvanised steel and aluminium. The high strength cabin is equipped with load cells to avoid over- loading, while the sophisticated electronic control system has a functional user- friendly panel. The two Saltec hoists are scheduled for installation in the first quarter of 2017.

Vertical transport solutions always need to comply with stringent safety parameters and the Saltec passenger hoists incorporate advanced security systems.

Mine stoppages highlight need for PDS technology More frequent government-ordered safety stoppages on mines – which demand a halt to a mine’s entire operation – highlight the need for a system that detects potential collisions underground and alerts person- nel to dangerous situations, says Booyco Electronics’ Continuous Improvement Manager, Jaco du Plessis.
