RAX Low Loader

You are here: Home » RAX Low Loader

With capacities from 150 tonnes to 800 tonnes the patented Bosich Rear Axle eXpanding low loaders are designed for transporting powered mine site equipment such as excavators, dozers and drills around mine sites. The low loaders can also be used to move any suitable objects like tanks and dragline and excavator buckets as necessary.


Our patented Rear Axle Expanding Low Loader is a breakthrough design that enables the rear of the loading deck to be lowered to the ground. This is accomplished by using a remote control to activate the hydraulically adjustable suspension cylinders.

Once the rear deck is on the ground the remote control is also used to pivot “expand” the rear wheels and lower the loading ramps to give the operators unrestricted access to pinpoint loads on the large deck.

Some models also have the loading ramps built in to the load deck for even quicker and simpler operation.

Other features include

The remote controlled one man operation is safe and quick and there is no need to disconnect the loader from the prime mover to load and unload equipment. This means safer and quicker operation throughout the process.

Integrated loading ramp at the beaver tail on 150t and 240t models. This reduces maintenance requirements and speeds loading times.

All hydraulics run from the prime mover so there are no ancillary pumping systems on the trailer…
