Hot spell exposes safety risks with power tools

While there is always the problem of security, the recent hot spell has also exposed safety risks.

With cordless power tools becoming more common for use off the grid, safety concerns are being raised about the fire risks of devices left unattended in tractors, utes and other vehicles.

The problem centres around lithium-ion batteries that can get very hot if left exposed to sunlight and, if temperatures get hot enough, could explode. Safety advisors suggest that with recent daily temperatures reaching the high 20’s, the internal temperature of parked vehicles can easily approach 40 degrees C when left in direct sunlight. As the lithium-ion battery is an essential part of devices such as mobile phones, laptops and power tools, they should always be stored correctly, preferably, in the case of power tool, with the battery removed from the tool.

Indeed, quite recently, this writer experienced the issue, when he left an i-Phone in the central cubby of an SUV, while he did a 15-minute dash around a supermarket. On his return, he found the phone, protected in a matt black case, was very hot to the touch and displayed a message that read, “This device is overheated, please allow to cool before use”.

In transport circles, lithium-ion batteries are classified as dangerous goods under the Dangerous Goods Code, so every effort should be taken to transport them safely and remove fire risks by storing them away from direct sunlight.

Case IH Wins EIMA Award for Optum Suspension System

With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.

The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.

In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.

Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.

Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”

Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.
