Louw Smit, sales director of Crane & Hoist Equipment SA, says that the company was able to offer the end user the most appropriate tower crane for the project and at the right price with full back up support over the duration of the eight month hire period. “It is all very to be able to supply pieces of materials handling equipment, but it is critical to be able to support these sophisticated machines in the field,” Smit says. “And this is in terms of the safe erection of the tower crane making sure that it complies with all the legislative requirements as well as being able to maintain and service the unit during its usage on site.” A Potain MDT 98 tower crane was selected for this particular project as it will provide a 1,2 t lifting capacity at a 55 metre radius allowing optimum materials movement on this fast track project. Significantly, this top slewing modular tower crane can be easily adapted for individual sites and brings optimum performance coupled with flexibility to a construction site. Smit that this particular tower crane was considered ideal for several reasons including that Relative newcomer to the tower crane and hoisting sector, Crane & Hoist SA has secured an order for the supply and erection of a Potain tower crane for the new Stor-Age Self Storage facility being constructed in Craighall. Cranes for Craighall Aurecon’s vision is to make use of drones on its projects ‘business as usual’ in the near future. The company is only a few months away from obtaining its Remote Operators Certificate (ROC) from the South African Civil Aviation Authority, at which point it will start using its drones on selected projects. Aurecon is currently using drones for the settling any disputes and claims,” says Matchett. An important advantage of using drones for Aurecon’s engineers is being able to conduct safer and more efficient inspections of high structures, unstable slopes, greenfield and wetland areas. “The aerial view and photogrammetric techniques will allow us to view these potentially dangerous areas normally accessed using ropes, scaffolding and other conventional methods. This is a space where Aurecon is as seriously concerned about safety as the aviation industry,” adds De Klerk. Drones to become ‘business as usual’

completion of the New Bugesera International Airport in Rwanda. The company obtained a permit from the Rwanda Civil Aviation Author- ity to take aerial footage of the project site. Aurecon’s pilot on site is using a DJI Phantom 4 Pro drone to fly in a grid pattern across the 500-hectare site and take over 5 000 photos per day. The drone photos are processed into an accurate aerial photograph that is detailed enough to identify plant, equipment and even tools such as spades and wheelbarrows. From this photogrammetric process, a 3D contour model is also created so that earthworks can be assessed from month to month. “Over time, we believe that Aurecon’s drones and team of pilots will grow to a point where we are able to cover all our major projects and selected smaller projects. We believe that the use of drone technology is going to add significant value to our service offering, while also aligning with government’s goal of obtaining better visi- bility of infrastructure projects throughout South Africa,” concludes Matchett. 

it is fast and simple to erect and that while it only requires a limited footprint it facilitates optimum reach on sites which are constrained. “This reach ensures enhanced productivity by ensuring that materials can be moved to where required with ease,” he says. Crane & Hoist Equipment SA was established as a specialist operation that supplies new and refurbished cranes as well as construction hoists to the sub-Saharan markets. The com- pany provides turnkey tower crane manage- ment and lifting solutions, and demand for its services has rapidly gained traction. 
