Power-Assisted Moving for Concrete Ballast Blocks & Heavy Event Equipment
The Concrete Block Electric Dolly is a powered, four-wheel hand truck built to move dense, awkward loads — concrete ballast blocks, generators, and other heavy commercial equipment — without a multi-person lift. It carries up to 750 lbs on level ground (500 lbs on a 3:1 slope), riding on four 13" flat-free, semi-pneumatic tires with a dual-drive-axle layout that keeps heavy, off-center loads stable instead of tipping or dragging.
A 950W direct-drive electric motor, powered by a removable 24V 35Ah sealed AGM battery, drives the unit at a variable 0 to 3.2 mph with a twist throttle and forward/reverse toggle on the handlebar. Typical runtime is 6 to 8 hours between charges, with an onboard 110V charger and an LED battery indicator. Safety systems include an automatic parking brake that engages the moment the throttle is released, smooth ramped power delivery to prevent sudden jolts under load, constant-speed control on inclines and declines, and an overload fuse protecting the drive system. If the battery runs out mid-job, the unit can still be pushed manually.
This is purpose-built for crews that ballast tents and structures with concrete blocks instead of ground stakes — common on asphalt, concrete, rooftop, and permit-restricted job sites where staking isn't allowed. See our Ballasting Guide below for how block ballasting fits into a compliant tent installation. The unit ships fully assembled via freight, made to order with a 1–2 week lead time; a liftgate may be required for residential delivery.

Ideal Use Cases
Concrete Block BallastingMoves heavy ballast blocks for tents and structures on sites where ground stakes aren't permitted.
Permit-Restricted JobsitesBuilt for asphalt, concrete, and rooftop installs where staking is prohibited.
Generator & Heavy Equipment Moves750 lb capacity handles dense commercial equipment beyond manual hand truck limits.
Reduced Crew SizeLets one operator move loads that previously required 2–3 people to lift or drag.
Loading Dock to Site StagingFlat-free tires roll smoothly across warehouse floors, gravel, and paved lots alike.
Multi-Block ConsolidationHopper design lets crews stage and move multiple blocks together instead of one at a time.
Frequently Asked Questions: Concrete Block Electric Dolly
How much weight can the Concrete Block Electric Dolly carry?
It carries up to 750 lbs on level ground. On a 3:1 slope, the rated capacity drops to 500 lbs for safe, stable operation.
Why does the capacity change on a slope?
Like any powered mover, braking and traction performance change on an incline. The 500 lb slope rating (3:1) ensures the automatic parking brake and drive system can safely control the load on grades, rather than rating the unit for its flat-ground maximum in all conditions.
What kind of tires does it use?
Four 13" flat-free, semi-pneumatic dual tires with a steel hub. They have a molded outer core and hollow center, so there is no air to maintain and no flat tire risk.
How long does the battery last, and how is it charged?
The removable 24V, 35Ah sealed AGM battery pack typically runs 6 to 8 hours under real-world use. It recharges through the onboard 110V charger, and an LED indicator shows remaining charge.
What happens if the battery runs out during a job?
The dolly can still be pushed manually without power, so a depleted battery does not strand the unit mid-job.
How does the braking work?
An automatic electromechanical parking brake engages the instant the throttle is released, and power is applied with a smooth ramp-up rather than a sudden jolt. An overload fuse also protects the drive system from damage.
What warranty is included?
90 days on wheels and tires, and 1 year on the chassis, electronics, powertrain, battery, and charger.
How is this different from a manual hand truck like the Folding Platform Hand Truck?
The Folding Platform Hand Truck is fully manual and built for lighter, 800 lb general event equipment. The Concrete Block Electric Dolly adds a 950W electric drive, automatic braking, and a hopper designed specifically for dense, heavy loads like concrete ballast blocks.
How does this compare to the Overland Mega Herc 36V?
The Overland Mega Herc is rated for a higher 1,200 lb capacity and carries a longer 3-year warranty, making it suited to high-volume professional operations. The Concrete Block Electric Dolly is purpose-built around ballast block handling at a lower price point.
How does it ship, and is assembly required?
It ships fully assembled via freight, made to order with a 1 to 2 week lead time. Residential deliveries may require a liftgate truck.
