What Is a Power Pusher? | The Heavy Load Mover Explained

A Power Pusher is a battery-powered industrial tug that lets one person push or pull wheeled loads weighing up to 20,000 kg (~44,000 lbs).

If you’ve ever tried to muscle a loaded trailer, a rack of parts, or a heavy machine across a warehouse floor, you know the struggle. That’s the problem Power Pusher solves. It’s the trading name of Nu-Star Material Handling Ltd, a brand of pedestrian-operated electric tugs designed for moving heavy wheeled loads in manufacturing, warehousing, and trailer-moving settings. Instead of a forklift or a crew of workers, a single operator steers a compact power unit that does the heavy pulling.

The concept isn’t new—the company traces its roots to an original 1960s Power Pusher used to push cars in garages—but the modern lineup is a far cry from that early model. The brand’s product family now includes the standard Power Pusher, the Super Power Pusher, the Trailer Mover, the PowerTug, and even an electric wheelbarrow, each built for a specific class of load.

What Can a Power Pusher Actually Move?

The short answer: whatever rolls on wheels. Power Pusher units are designed for pushing and pulling wheeled loads—trailers, tanks, vessels, paper rolls, and other heavy industrial equipment—in environments where a forklift won’t fit or isn’t practical. The key capability is that one pedestrian operator controls the entire operation.

Load capacities vary widely by model, so you can’t assume one rating fits all. Here’s how the current lineup breaks down:

What Makes a Power Pusher Work?

The standard Power Pusher runs on a 400W or 550W, 24V DC motor with a 125A programmable controller. It draws power from two sealed VRLA gel batteries that are IATA approved, meaning they’re safe to ship by air freight. The on-board charger is IP68-rated, handles multiple input voltages, and delivers a 2 x 10A output.

Several design details make these units practical for daily industrial use. The wheels are foam-filled and puncture-proof with free-wheel hubs, so a flat tire won’t shut down your operation. Regenerative braking comes standard, which helps extend battery life while giving the operator control on slopes.

Safety features include a keyswitch on/off, variable throttle, hand and wheel guards, emergency reverse, a horn, a battery gauge, a main isolator fuse, and an emergency stop. For specialized environments, options include motion bleepers, strobe lights, non-marking tyres, stainless steel construction, and even ATEX Zone 1 certification for hazardous areas.

One thing to keep in mind: the stated load capacities are application-dependent. The 20,000 kg figure for the standard Power Pusher assumes the right conditions—a level surface, suitable wheels on the load, and proper operation. Your actual results may differ.

Is a Power Pusher Right for Your Operation?

If you regularly move heavy wheeled loads and you’re tired of manual labor or tying up a forklift, a Power Pusher can pay for itself quickly. It’s a fit for manufacturing floors, warehouses, trailer yards, and any setting where heavy things need to roll from point A to point B without strain.

Before you buy, match the model to your specific load weight and your operating environment. If you’re moving trailers in a yard, the HD Trailer Mover is built for that job. If you’re maneuvering machinery inside a plant, the standard Power Pusher or PowerTug might be the better fit. And if you work in hazardous areas, confirm whether you need the ATEX Zone 1 option, since that’s not standard on all units.
