Electric tugs

What is an electric tug?

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 industry that, amongst others, also covers fork lift trucks, overhead cranes and pallet jacks. *Links to relevant pages showing these products*

Although ‘electric tug’ is perhaps the most commonly used term, suppliers and customers regularly use a range of other names that include battery powered tugs, electric hand trucks, electric tuggers and pedestrian operated tugs. (all terms for which we are well optimised) [Wikipedia may require links to published examples of these terms being used, these would be the references shown at the bottom, you occasionally see this flagged as “citation required”] http://www.packmule.com/electric-tugger/

The tugs move loads across a single level. They do not lift the load clear of the ground which is why the load must be on wheels. If the load itself does not have wheels, it would be placed on a wheeled platform often referred to as a trolley, bogie or skate. The tug connects to this wheeled platform just as a fork lift truck links to a pallet in order to move a load sat on it.

In most cases a steel coupling (male) attached to the machine itself connects to a corresponding coupling (female) bolted to the load’s bogie. A second bogie or multiple bogies will each have identical female couplings attached to them so that a single male coupling attached to the machine can move them all without alterations.

How do they work?

An electric tug relies on the principal of tractive effort. The machine, once secured to the bogie, will lift a portion of the load ensuring the load’s wheels remain on the ground. 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. allows the tug to move an object much larger and heavier than itself. As a tug does not lift its load clear of the ground it does not have to conform to the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), therefore an operator does not need a licence. *Link to HSE LOLER page and Wikipedia page*.

Where are they used?

Electric tugs are used in many industry sectors. Some common applications include;

Retail - To move heavy roll cages from a delivery vehicle’s tail lift to the supermarket’s storeroom or long trains of empty roll cages.

Healthcare – To move bariatric beds, waste bins (including multiple bins at once), linen cages and gas bottles.

Pharmaceutical – To move chromatography columns within laboratories.

Airports – To move long trains of empty luggage trolleys.

Food and beverage – To move industrial mixing bowls full of product.

Manufacturing and Assembly –

Automotive - To move heavy products such as vehicles down a production line.

Glass – To move heavy stillages used to hold glass through production.

Wind Turbines – Moving turbine blades up to 50 m in length through production.

Aerospace – To move wing assemblies, invar tooling, turnover jigs etc.

Boat building – To move luxury yachts on cradles through production.

Brick and ceramic – To move product into and out of a kiln.

Modular buildings – To move buildings through production and completed buildings into storage.

Cable and wire reels – To move unwieldy reels in production.
