Hewlett fits anti-roll alarms to dump trucks

Aaron Morby 13 years ago

Leeds-based Hewlett Civil Engineering has fitted alarms to its articulated dump trucks to prevent rollovers.

The rollover prevention device consists of a sensor that is attached to the dump truck with a receiving unit that is fitted to the dashboard of the truck cab.

If the data sent by the sensor exceeds the safe theoretical rollover threshold for the vehicle, the device alerts the driver.

Hewlett’s major client Scottish and Southern Energy is so impressed by the device that it is considering making the safety measure a requirement on future projects.

With the help of Bolton supplier Transport Support, Hewlett was able to source a device which could easily be fitted to the rear axle of an articulated rear tipping dumper.

Ian Dick, Health and Safety Director for Hewlett Civil Engineering, said: “We took the initiative to collaborate with our business partners Scottish and Southern Energy and Jacobs Engineering to develop the rollover warning device because we want to do all we can to reduce the risk of dumper truck rollover.”

Dick said: “The rollover prevention device offers drivers both visual and audio warnings when the vehicle is approaching its rollover threshold, allowing the driver to take corrective action before a rollover occurs.

“We would encourage all contractors to adopt a device. It is relatively simple and inexpensive to install and can potentially save lives.

Hewlett trialed the rollover warning device on its fleet at Cross Green in Leeds to test the system’s benefits.

“Our drivers said they feel safer because they have greater awareness of the rollover threshold of their vehicles. There is no doubt that this simple yet effective device really makes our fleet safer.”

    Anti-roll device spec

  • Provides plant operators with an indication of the angle of the rear body in relation to the critical tipping point.
  • Provides additional information to the operator to allow an informed judgement.
  • Is simple to read and understand, does not distract the operator from the task in hand.
  • Works in forward, reverse and tipping mode.
  • Can be modified to interrupt the vehicle’s built in stereo radio/CD player.
  • Is tamper proof and is of solid state construction (no moving parts),
  • Continually displays the angle of the tipper body.
  • Can be adjusted to alarm when the vehicle’s ‘skip’ reaches a particular angle.
  • Can be connected to external speakers at either side of the skip body to warn personnel in close proximity to the vehicle.

Jacobs Safety Manager Phil Howe said: “This is an example of applying the principles of ‘Beyond Zero’ and demonstrates a common understanding between the people involved in the project.

“It also cements further the relationship between Jacobs, SSE and Hewlett Civil Engineering and confirms Hewlett’s ability to apply effective solutions and improve standards in the construction industry.”
