In the last 10 years in Australia there has been one fatality and over 45 serious injuries as a result of bottom guard (or ‘belly plate’) removal.

Across the world in the same period there have been 5 ‘recorded’ fatalities and over 200 recorded serious injuries.

Belly plates on large equipment such as dozers typically weigh hundreds of kilos and are prone to accumulating debris over the course of their normal operations, which increases their weight further and obscures the critical components that secure them in position.

With traditional belly plate removal techniques, there is a high risk of crush injuries, as the mechanic has to crawl under the vehicle to line up the bolt holes. These vehicles are often large dozers weighing tens of thousands of kilograms, with belly plates that weigh If the plate is not appropriately restrained or supported, uncontrolled movement can occur when loosening nuts or bolts, which poses a huge safety risk if a mechanic is working directly underneath 500kg of steel.

If a dozer needs servicing while still in the field, other problems can occur, such as poor lighting, poor ventilation or inadequate space. These create significant hazards for a mechanic who needs to be positioned underneath the dozer to carry out maintenance.


The belly plate can be locked, secured or restrained, but the biggest safety concern is still having the mechanic placed directly underneath the dozer, or heavy vehicle. Safety MITS’ TED (Tracked Elevating Device) is the ideal solution that eliminates the human element from the critical lift stage underneath equipment, by allowing remote control of the lifting device.

TED can travel across any terrain and can safely lift up to 800kg. It has a 360° turntable at the top, which makes lining up ball joints safer, quicker and easier than the conventional methods using slings and chain block.

In addition to making belly plate removal safer, it also makes it significantly more efficient. Safety MITS collected customer data from Thiess, Peabody Energy and Glencore over a one year period and found that by using TED to remove and install belly plates they were able to reduce work time by 73.5% while using one less mechanic.

These savings don’t just apply to belly plates either. TED can also be used for equaliser bars, cutting edges, steer cylinders, load rollers, sound suppression, engine sumps and many other applications.

TED is designed and manufactured in Australia and is built to withstand the harsh environments that heavy equipment works in every day. It is built with total compliance to Australian and New Zealand mining standards (ASNZ 4240) to ensure the highest levels of safety are achieved.

TED comes with a range of attachments, which can be easily installed and removed at a moment’s notice.

These include:

  • The Rhino Stand Locator, which allows you to locate stands underneath elevated bulldozers without crawling underneath the suspended load yourself.
  • The Cutting Edge tool, which has been designed to assist in the safe removal and installation of cutting edges on bulldozers, graders scrapers and loaders.
  • The Load Roller Cradle, which is designed to assist in the easy removal and installation of track roller components on bulldozers, drills and excavators.
  • The Tie Rod and Steer Cylinder Cradle, which is designed to assist in the safe removal and installation of steer cylinders and tie rods. The cradle conveniently bolts to the turntable on top of TED allowing it to rotate 360°.
