Product feature: FPV20 OSA Pulveriser

The FPV Pulverizer Series has been designed to deliver increased production and performance for secondary demolition and recycling

"It smashes concrete big time": that was Steve Timpany’s opening comment when asked about the performance of his company’s new FPV20 OSA Pulveriser. OSA says they are often recognised as a benchmark for demolition equipment and their world-leading range of demolition attachments is the brand of choice when it comes to the demolition of concrete structures and then processing of concrete, demolition of steel structures, scrap yard processing, and demolition handling equipment.

Steve’s company, Timpany Landfill, is operating their new OSA pulveriser on a 25-tonne excavator, and he says he has nothing but praise for the attachment’s performance.

"These heads are well made, the back-up service has been superb, and it has added an extra dimension to our overall business capabilities."

Further north at Gisborne, an FPV30 is being used to help Eastland Port’s wharf 7 and slipway rebuild project, some of which is more than 100 years old. When completed, the re-development will allow for two 185- to 200-metre vessels to berth simultaneously.

"We’ve only had the FPV 30 in operation for about three months, but it’s a beast of a crusher head, and while it’s still early days, we’re happy with both the performance and quality of the clean fill being produced," says operations manager Rod Blake.

The OSA FPV30 is operating on a 30-tonne excavator to crush concrete sourced from the original wharf structure for use as clean fill for the rebuild. This process, which will also utilise recycled concrete feedstock from demolition sites around Gisborne, will help reduce the need to send waste materials to landfill as well as reduce the need for import of rapidly diminishing quarried aggregate resources.

In-situ concrete recycling also delivers additional environmental benefits through significant reductions in truck movements and lower emissions. The port’s owner, Eastland Group, is a signatory to the Climate Leaders Coalition so the environmental benefit generated by this use of recycled materials is in line with its commitment to the reduction of greenhouse gasses from all of its businesses.

The FPV Pulverizer Series is truly ground-breaking, says OSA, and has been designed to deliver increased production and performance for secondary demolition and recycling.

Featuring HARDOX structures, the FPV design also includes a reversed cylinder to protect the rod from accidental hits as well as an innovative pressure relief valve that protects the attachment from high pressure. Operational productivity is maximised through the pulveriser’s regenerative capability that allows for fast idle movements and maximum strength thrusts within just seconds.

"When it comes to unrivalled power and performance, OSA products are world-beaters and in an absolute class of their own," says Boss Attachments managing director Paul Herbison.

Waikato Demolition’s MC40 Multishear makes short work of steel and concrete

Hamilton-based Waikato Demolition Ltd has been operating an OSA SH35 demolition steel shear for the past four years and has been impressed with its performance. "We purchased it to help with some of the specialised projects that our company undertakes," says company director Andrew Proudlock. "It packs a real punch, and its power-to-weight ratio performance is quite staggering; it has made a real contribution."

Waikato Demolition has also just purchased its fifth OSA GR Series Rotating Grapple, which features a full 360-degree rotation for precision placement of wide-ranging demolition site materials. They’ve also purchased an OSA MC40 with a multi shear head, which Andrew says, enables both steel and concrete to be cut with one tool.

Boss Attachments Ltd distributes the OSA range throughout New Zealand, Australia, and the Pacific Islands. In addition to demolition shears, the Italian-manufactured OSA range includes demolition tools, pulverizers, multi-systems, hammers, and rotating grabs.
