Heavy-duty electric tuggers tow the loaded carts, racks, and trailers that no one should be pushing by hand. These are walk-behind machines built for warehouses, manufacturing bays, and docks, where one operator needs to move loads that used to take a small crew or tie up a forklift. You steer from a handle and walk alongside while the tugger does the pulling.
The four models here climb in a clean capacity ladder. The Pony Express 1065 pulls 5,000 lb, the 1065-HD pulls 6,500 lb, and the 1065-XHD pulls 7,500 lb, all on a flat surface. Above those sits the AC Tugger 25K plus, rated for 25,000 lb on casters and 100,000 lb on rail for rail-car and aircraft work. The three 1065-class models run a 24V drivetrain and the AC tugger runs a 48V AC drivetrain. Each carries a deep-cycle AGM battery good for an 8-hour shift, regenerative braking, and an automatic holding brake, and the frame and motor are covered by a 5-year warranty. Top speed is about 3 mph.
One thing to be clear about up front. These tuggers tow on level concrete. They do not lift, and they are not ride-on tractors. If you need to raise a load or run a long ride-on train across a plant, a scissor-lift cart or a forklift is the better tool, and we would rather point you there than sell you the wrong machine.

A heavy-duty electric tugger is a walk-behind cart mover rated to pull 5,000 lb or more on a flat surface. Our four heavy models pick up where the standard tuggers leave off. The compact 1061-HD and 1062 top out at 2,000 lb, which is plenty for a single loaded cart. Once you start coupling several carts into a train, or towing one very heavy rack, you have moved into 1065-class or AC tugger territory.
All four are pedestrian-operated. The operator walks behind, grips the handle, and the center-wheel or AC drivetrain pulls the load along on its own casters. None of these machines lift. They tow horizontally, which is exactly what you want for moving wheeled loads across a warehouse, a manufacturing bay, or a dock. For the broader range and the lighter models, see our full lineup of walk-behind electric tuggers.
Walk-Behind Tuggers From 5,000 to 25,000 lb
Four pedestrian-operated models that move loaded carts so one person can do the work of a crew
25,000 lb Top pull on casters (AC Tugger, up to 100,000 lb on rail)
Pick by the heaviest load you actually move, the three 1065 models cover 5,000 to 7,500 lb on a 24V battery, and the AC Tugger steps up to 25,000 lb on casters for true industrial duty.
The AC tugger is the heavy end of the line, pulling up to 25,000 lb on casters with one walk-behind operator.
Match the rating to the heaviest single load you tow, then add some headroom for ramps and startup. A tugger rated for 6,500 lb on flat concrete will work harder on an incline, so size up if your route has a grade.
Here is one rule we have learned from years of fitting these for plants. Do not buy to your average load, buy to your worst load. The day you need to move the heaviest rack is the day an undersized tugger stalls on the ramp.
Raphael’s sizing rule. Rate the tugger for your heaviest load plus the grade. A 6,500 lb pull capacity is measured on flat concrete. Put that same load on a 5 degree ramp and the effective demand climbs fast, because the drivetrain now fights gravity and rolling resistance at the same time. When a customer has any incline on the route, I move them up one model. The 1065-HD instead of the 1065, or the 1065-XHD instead of the 1065-HD. A few hundred dollars of headroom is a lot cheaper than a stalled load and a strained motor.
The 1065, 1065-HD, and 1065-XHD share a compact 25 inch long by 24 inch wide footprint with center-wheel drive, so they pivot in narrow aisles better than their pull rating would suggest. Center-wheel drive turns the machine around its own midpoint rather than swinging a long tail behind it. In warehouses with tight cross-aisles or crowded dock areas, that short body matters more than raw capacity. The AC Tugger 25K plus is a larger machine built for open rail and dock work, not packed aisles.
For long hauls across a large plant, runtime and battery endurance decide the pick. Every 1065-class tugger runs a 70 Ah AGM battery rated for 8 hours of operation per charge, with a recharge of roughly 4 hours. That covers a full shift of repeated trips. The two-speed control gives you 0 to 1.5 mph for precise coupling and 0 to 3 mph for the run between zones. The AC Tugger 25K plus adds a 100 Ah AGM standard battery, with a 120 Ah lithium iron phosphate option for facilities that want faster opportunity charging between rail moves.
NIOSH guidance on manual material handling puts a practical ceiling on sustained push force at roughly 50 lbf for most workers. A loaded 5,000 lb cart on good casters can demand far more than that just to start moving, and that strain lands on backs and shoulders. A powered tugger takes that force off the operator entirely. The motor starts and stops the load, and the operator only steers. For the safety case behind walk-behind powered trucks, see the OSHA standard for powered industrial trucks (29 CFR 1910.178) and the ANSI/ITSDF B56.10 standard for pedestrian-controlled industrial trucks. You can read the push and pull ergonomics in the NIOSH ergonomic guidelines for manual material handling.
They tow, they do not lift. If you need to raise a load to a work height, look at a powered scissor-lift cart instead of a tugger. They are also walk-behind units, not ride-on tow tractors. If your operation runs long multi-cart trains over long distances and you want a seated driver, a ride-on tractor or a Crown-style unit is the better fit, and we would rather point you there than oversell a walk-behind. For loads at or under 2,000 lb in a single cart, the lighter and lower-cost compact electric tuggers are the smarter buy. And when the job is carrying a flat load rather than towing wheeled ones, our motorized platform carts are the right category.
Heavy-duty tugger sale prices run from $7,228 for the 1065 up to $21,681 for the AC Tugger 25K plus. Every 1065-class model and the AC tugger carry a 5-year warranty on the frame and motor. All four are US-built EK Tech Pony Express units. Standard equipment across the line includes regenerative braking, an automatic holding brake that sets when you release the throttle, an onboard UL or cUL listed smart charger, an emergency stop, a horn, and a keyed switch. Each unit ships with a 21-day manufacturer demo program, so you can prove the fit on your own floor before you commit.
Our heaviest walk-behind model, the Pony Express 1065-XHD, pulls 7,500 lb on a flat surface. Above that, the AC Tugger 25K plus is rated for 25,000 lb on casters and 100,000 lb on rail.
All four heavy-duty Pony Express tuggers are walk-behind, pedestrian-operated machines. The operator walks alongside and steers from a handle at up to 3 mph. We do not sell ride-on tow tractors. If you need a seated tractor for long multi-cart runs, we will refer you to a better fit.
The 1065, 1065-HD, and 1065-XHD run a 70 Ah AGM battery rated for 8 hours of operation per charge, with about a 4 hour recharge. The AC Tugger 25K plus uses a 100 Ah AGM battery, with an optional 120 Ah lithium iron phosphate pack for faster charging.
Every 1065-class tugger and the AC Tugger 25K plus carry a 5-year warranty on the frame and motor. They are US-built EK Tech Pony Express machines and ship with a 21-day demo program.
The Pony Express 1065-HD at 6,500 lb is the model most warehouse buyers choose. It tows a full multi-cart train with margin to spare and keeps the compact 25 by 24 inch footprint that turns in tight aisles. Step up to the 1065-XHD only if your heaviest load passes 6,500 lb or your route has a meaningful grade.
