The new technology from PMSA, a manufacturer of brick, block and paving machines, was unveiled at Totally Concrete 2016, held at Gallagher Convention Centre in May this year. The Ultravibe vibrators can be retrofitted to the company's range of existing machines, but will also form the basis of a brand-new machine under development. "This will be a large-pallet, 1 400 mm by 1 100 mm, production-board machine incorporating all of our latest advances in its design," Walter Ebeling, managing director, PMSA, reveals. "We undertook these latest developments in order to allow our customers to be more productive. The best means of achieving this is if your equipment is more reliable."
Lambson's hire operates a fleet of fit-for-purpose concrete preparation equipment that caters to the needs of this specific sector of the market. The new grinding and polishing machine will join this fleet and offers several important features to hirers. The lightweight machine combines high diamond speed with balanced weight, placing it in a class of its own when compared to other machines with a 650 mm width. This, coupled with the variable-speed controller, which facilitates grinding and polishing at the optimal speed, ensures high productivity. It is capable of efficiently flattening or levelling a floor and can also be used to grind a surface with a shallow indentation or dish effect.
A well-maintained cooling tower is essential for optimal system performance. Leading rope access specialist Skyriders is demonstrating the most efficient way of achieving this result in a project to repair a 140 m high cooling tower at a petrochemical plant in Secunda, Mpumalanga. The petrochemical plant engaged the services of Aveng Grinaker- LTA, a specialist in concrete repairs, to execute the project. Aveng Grinaker LTA, in turn, saw the need to utilise rope access in order to reduce the downtime incurred and increase the overall safety of the project. "We have been assisting Aveng Grinaker-LTA with rope-access related services for a few years," Mike Zinn, marketing manager, Skyriders, comments. Rope access allowed the team to move freely, while affording a great deal of flexibility on the massive cooling towers, thereby accelerating the project's progress.
