With the Premiertrack 600, McMahon Services can now crush and transform demolition and construction waste into aggregates and fill material. This brings both cost and environmental savings to clients by significantly reducing quantities of construction and demolition waste otherwise transported and processed off site.

The 69t Premiertrack 600 is equipped with a single toggle jaw with an adjustable hydraulic setting able to crush materials with material strengths of up to 500kN, reducing materials into sizes between 75mm to 200mm. Materials are fed into the crusher through a 9.3m3 hopper. A troughed conveyor belt deposits crushed materials at a discharge height of 4.0m to produce stockpile volumes of 136m3.

The heavy-duty crawler tracks and a climb grade rate of 30o ensures that the Premiertrack 600 is mobile on site so it can be relocated continuously to adapt to staged works projects. It also features an inbuilt dust suppression system.

The Premiertrack 600 has provided significant savings to demolition projects across South Australia including the Charles Sturt Industrial Estate Demolition works, the Augusta Power Stations Decommissioning and the Former Football Park demolition project.

Hammelmann High Pressure Pump Cuts Straight through Concrete

McMAHON SERVICES HAS EXPANDED ITS SERVICE CAPABILITIES THROUGH THE PURCHASE OF A HIGH-PRESSURE HAMMELMANN PUMP THAT CAN PRODUCE 1000 BAR (10MPA) PRESSURE AT 100L/M OR CONVERTED TO PRODUCE 1400 BAR (140MPA) PRESSURE AT 70L/M.

The 1000 bar setting allows for cleaning of any type of industrial surface and the insides of tanks using a specialised cleaning head attachment.

The 1400 bar setting uses a Conjet Nalta 101 attachment that creates sufficient pressure to hydro-demolish concrete. This is ideal for exposing corroded reinforced steel bars so they can be treated and then resurfaced.

The unit is confined within a 6.0m by 2.4m wide by 2.4m high container for easy transport on the back of a truck, making the unit highly mobile.

The first project were McMahon Services successfully used the Hammelmann High Pressure Pump was on was the Former Royal Adelaide Hospital Stage 1 Demolition Works.
