Columbus electric wheel nut runner is primarily intended to be used for loosening and tightening of the wheel nuts on heavy vehicles - trucks, buses, trailers, construction equipment etc. Columbus nutrunners can of course also be used for other tasks where location and space allows.

Columbus nutrunner has been manufactured by Columbusmaskiner AB since 1950 's.

Columbus wheel nutrunners are very comfortable and easy to work with. All controls are easily accessible placed on both shafts of the machine. In comparison to a conventional air impact wrench, Columbus electric wheel nutrunner is very ergonomic, quiet and superior in force. They are able to remove even the tightest nut. They give no vibrations that can damage your hands or other body parts. You automatically get a natural working position when working with a Columbus nutrunner.

Columbus nutrunner has a rotating flywheel, releases its kinetic energy in the form of a blow to the wheel nut. This allows the wrench to work with very great force, compared with conventional air nutrunners. A spring system makes the machine body almost weightless and it requires minimal force when leveling.

The machine socket tube is provided with a one inch square drive for power sockets.

Spare parts, power sockets and adapters are always in stock for fastest delivery.
