An electric tug is a battery-powered and pedestrian-operated machine used to move heavy loads on wheels.
The machines form part of the material-handling equipment field that, amongst others, also covers forklift trucks, overhead cranes and pallet jacks.
The tug connects to this wheeled platform just as a forklift truck picks up a pallet to move a load placed on it.
This is achieved via the machine's hydraulic mast which is designed to create downforce on the drive wheel immediately beneath it.
It is the traction generated from this process that allows the tug to move very large and heavy objects.
