When it comes to pushing or skidding extremely heavy loads, the electric power bar (also known as the Powerbar Electrical system) is a reliable tool—especially when paired with a dolly system, tank rollers, or air skates. At LGH, our electric power bars are available as part of our electric dolly rental fleet, trusted across industries for their strength and versatility.
But like any powerful tool, proper use is critical to avoid damage and maintain safety.

Think of it as an electric dolly designed to move heavy items horizontally—not lift them. It’s engineered to push (not pull) loads across surfaces, typically working in tandem with low-profile dollies or other load-moving equipment.
Despite its power and convenience, misuse is one of the leading causes of downtime and damage.
1. Placing the Load on Top of the Power Bar
This is the #1 mistake. The electric power bar is not a platform—it’s a pushing device. Always place the load on the two front tongues, never directly on top of the unit.
2. Wheels Stop Turning While Motor Runs
If the wheels aren’t turning but the motor is running, chances are the spur gear or motor cluster is sheared. This usually results from reversing directions before fully stopping, which places undue stress on the internal components.
Pro tip: Come to a complete stop before reversing direction to avoid damaging the drivetrain.
3. Circuit Breaker Keeps Tripping
This can often be traced back to incorrect power cord setup: using a cord that’s too long or too thin of a gauge, or inadequate amperage supply (less than 20 amps).
Always confirm your cord meets the required gauge/length specs and you’re on a clean, undisturbed 20A circuit.
Electric Dolly Operating Best PracticesTo keep your electric dolly system in top shape, follow these tips:
• Push only – never pull a load
• Use the manufacturer’s care manual before starting
• Ensure the floor is clean, level, and free of debris
• Adjust the bar’s height for optimal leverage
• Apply downward pressure on the handle to improve grip
• Never set the load directly on the body
• Use the two tongues for all load contact points
