Avoiding crane collapses

Crane collapses on construction sites are not uncommon enough. Earlier this day, in a more publicized incident, a large mobile crane collapsed in a South Indian coastal City.

 

Crane operators and the individuals and entities that supervise them and also the maintenance personnel should adhere  not only to the regulations set forth by the legal authorities, but also to the particular crane manufacturer’s safety guidelines and applicable industry standards, such as those developed by the ASME, OSHA etc.

 

Collapse of a crane is a reportable dangerous occurrence as per the factories act in India and shall be reported to concerned authorities.

 

So what can you do to prevent crane collapse and related deaths?

 

1.       Check if the crane operator is authorized to operate the particular type of crane. If there are some changes (mostly like technological advancements in new models) train all crane operators on the functionality of all new cranes. Ensure the personnel who can most affect the safety of crane operations are adequately trained and qualified to do what they’re doing. This includes, but isn’t limited to, operators, riggers, and signal persons.

2.       Ensure the crane is inspected, maintained, and set up in accordance with the OEM guidelines, and legal requirements at minimum.

3.       Follow relevant standards, particularly with regard to crane operations in proximity to power lines.

4.       Complete an appropriately detailed crane hoist plan in advance to ensure the hoisting operation is planned and the necessary details have been considered and provided for in the plan. As a best practice implement critical lift permit for load testing work. The permit shall be issued after ensuring safety of people involved and also the safety of people working in nearby locations.

5.       Ensure all limit switches and sensors are working.

6.       Ensure that the hoist does not move downwards freely.

7.       Check that the wire rope is properly seated. Ensure that it is not twisted, kinked or damaged.

8.       Determine the exact load and understand the balancing requirements for the load (Do not rely only on the load indicator in the crane).

9.       Before putting the crane to use, test run the crane the full length of the runway and bridge span to ensure no obstructions will interfere with the crane travel motions. Test that all motion’s travel speed match the designed specifications.

       Don’t assume because you’re renting a crane with an operator that the crane rental firm will run point to point and ensure safe crane operation. It is quite likely, that the rental agreement you signed says the other way.

🌍 Embracing Sustainable Living, One Step at a Time! 👣

Dear Community, I recently encountered a common yet often overlooked problem - the sole of my running shoes decided to part ways with me.  🙄  Rather than rushing to buy a new pair, I decided to take a small step towards sustainability and repair them with Fevicol shoe fix. (I could have run down to a good cobbler, but I didn’t know anyone nearby) This experience got me thinking about the simple ways we can contribute to a more sustainable future. It's not just about big eco-initiatives; small, individual acts matter too.   Sustainability isn't just about solar panels and electric cars; it's about reusing, repairing, and repurposing in our daily lives. In this fast-paced world, we often forget that the most eco-friendly product is the one we already own – for the production of which, raw materials were used, processed in factories, transported and displayed in a shop until it was bought for use. So the way in which we as an end user can contribute is by prolonging its lif...

Risk Factors in Landslide Disaster Emergency Rescue

In the wake of the horrible landslides in Wayanad district of Kerala, among other articles and news, I came across a write up by a disaster management expert from the United Nation. A portion of his article translates roughly to 'An area that met with a disaster requires people with special skills. Even if there are small things to do (like serving food), some experience is required; such as the presence of mind to deal with disasters when they are seen in person, and benevolent behavior towards those affected by the disaster comes from the experience handling such situations.' this inspired me to give a thought on the the delicasies and risks involved in the Emergency rescue. Watch the videos running on news channels - you will come to know that the emergency recue after a landslide is no child's play. Landslide disasters caused by heavy rainfall pose significant risks to both rescue teams and affected communities. Understanding these risks is crucial for ensuring the saf...

The Influence of Childhood Team Sports on Adult Behavior

Recently while on job, I had an opportunity to have an engaging conversation with a business leader. The late evening discussion then went off topic, maneuvered smoothly through the passionate field of behaviour sciences and delved then into some thought provoking questions on where it is leading to in the world being increasingly dominated by AI and ML. On a similar front, another fact that has triggered my curiosity is that organizations are working hard to find leaders who can adapt to changes and provide necessary answers by implementing all available leadership development programs. During the recent years, learning & development leaders have manifested an increasing interest in engaging personalities from the sports sector, proof of this is the increasing number of athletes and coaches who participate in leadership programs offering their insights and experiences transferable to the businesses. These intrigued me to do a slew of internet searches which led to reading a co...
