Mines inspectors repeatedly identify plant such as shaft reliners, hopper trolleys, workshop mobile jib cranes and other multi-purpose lifting devices in poor condition and without maintenance and inspection records. These are classified plant as defined in regulation 6.1 of the Mine Safety and Inspection Regulations 1995 (MSIR). For plant with a lifting capacity over 10 tonne, they are registerable as required by MSIR r. 6.34. All others are subject to duty of care requirements under MSIR r. 6.2.
Subject: Structural failure of fixed conveyor stacker

Summary of incident
Note: The Department of Mines, Industry Regulation and Safety’s investigation is ongoing.
The information contained in this significant incident report is based on materials received, knowledge and understanding at the time of writing.
In February 2019, a fixed conveyor stacker collapsed during normal operation. Other than the temperature reaching 47°C, there were no extreme weather events at the time nor any abnormal operational loads. It was not running at full capacity at ...

Pressure Relief Valves (PRV’s) are devices used to release pressurised fluid from a wide variety of Pressure Vessels. PRV’s are used to maintain optimal pressure within a system, thus protecting the vessel from becoming overpressurized which can potentially cause damage or failure of a vessel. Pressure build-up related damage can be costly as well as a health and safety risk. PRV’s act as the main safety mechanism of a pressurized system (see ...
Champion Driver Mat Kennedy does it again at Bunbury. Bunbury Speedway has been a happy hunting ground for the TKR Team in recent meetings. Mat recently won his 3rd Feature in succession at his favourite Bunbury Track.
They say good things come to those who wait. Now, the wait is over for launch of AME’s new Classified Plant Management System (CPMS), and it’s definitely a good thing!
Over the last 18 months, we’ve been working hard to upgrade the system to offer an even more streamlined and easily accessible solution. Think: an easy-to-use, single point portal for all documentation, reports, photos, registers and plant records*, available 24/7 from anywhere you have an Internet connection. Pretty neat, right?
Well, our ...
Following the success of our “Difference between SWL/WLL/MRC” article around the world, another area of confusion is the difference between a Ton and a tonne.
Let’s be clear from the start: ‘Ton’ and ‘tonne’ are not equal, and it’s not just about the spelling.
Both are a unit of weight, a Ton is an Imperial measurement (still widely used in the USA), and a tonne is a Metric measurement.
However, they’re not interchangable for each other. Each has a ...
Wire ropes used in cranes & hoists for lifting purposes will experience deterioration throughout their entire service lives. Deterioration occurs through two principal mechanisms, namely, external and internal fatigue, which is caused by bending over sheaves or drum windings and crushing, which is caused by multilayer drum spooling. Another major cause of deterioration in a wire rope is the lack of lubrication.
What is external and internal fatigue?
During its operational life a wire rope is exposed to repetitive bending stresses. This will ...
Do you own pressure equipment?
If so, it’s important to understand the mandatory requirements and applicable Australian Standards (AS) to not only ensure your equipment is safe to operate, but also avoid fines that may come with non-compliance to Australia’s current safety laws and legislation.
So, what are we referring to exactly when it comes to pressure equipment?
The most common type of pressure vessel used is an air receiver for the storage of compressed air. Other types of pressure equipment include: accumulators, ...
Do you know your legal responsibilities if you own Plant, Machinery or Equipment?
As an owner of plant, machinery and equipment you bear an enormous responsibility to maintain safety standards in order to protect yourself, your staff members and to adhere to the laws and regulations of the country.
Unfortunately, accidents involving machinery and equipment continue to occur all over Australia. Over the period 2006 to 2011, SafeWork Australia has reported a total of 188 fatalities associated with unsafe design of machinery, ...
Crane failures continue to dominate the headlines, with several incidents that have occurred over the last few months. Many of these incidents are a result of overloading the crane or operating the crane outside of its working envelope.
Operating any crane beyond its rated capacity has the potential to cause a catastrophic failure of the crane, its support structure or both due to associated loss of control of the load. When control of the load is lost, workers ...
