Contact UsZonzini's stair climbing dolly: Perfect for moving tall objects
Written by William Nicholls | August 4th 2025
Some jobs you see coming from a mile away. Others only hit you when you’re already stuck on the stairs with a super-heavy door tilted at an impossible angle on a legacy stair climbing dolly, your crew swearing under their breath, and your customer peeking nervously from around the corner.
That’s the moment you realize a regular stair climbing dolly just won’t cut it.
Welcome to the world of moving tall, heavy, and high-center-of-gravity objects, such as doors, windows, bookcases, marble slabs, and security panels, through staircases, corridors, and door frames never built with logistics in mind.
So, what should a busy material handling crew do? When moving tall objects, teams should consider the Skipper Plasmoid: Zonzini’s electric stair climbing dolly engineered for the kind of jobs that make even seasoned movers groan.
The tall order: Why height changes the game
A standard residential ceiling is typically 8 feet high. Most staircases are narrow, some barely wide enough to fit a standard fridge. Now imagine trying to transport an 8-foot fire-rated door or a 7-foot-tall window; tipping the load upright is impossible, and keeping it stable while horizontal is a risky balancing act. This is where most traditional moving solutions hit their limits.
Just take a look at the average weights of tall freight, as analyzed by Zonini, a renowned manufacturer of electric stair climbing dollies. These weights are often incompatible with your run-of-the-mill, manual stair climbing dolly.
| Type of goods | Average weight |
| Doors, reinforced, windows | 220–440 lbs |
| Plate glass or marble | 660–880 lbs |
| Cupboards and wardrobes | 110–330 lbs |
| Sofas | 220–440 lbs |
| Electric control panels | 440–880 lbs |
| Large tables (including billiard tables) | 110–770 lbs |
| Pianos | 770 lbs |
| Gas cylinders | 440–880 lbs |
Goods this tall aren’t just heavier. They’re awkward. Their center of gravity sits higher, making them prone to capsizing. They often cannot be carried in an upright position due to ceiling clearance, and moving them parallel to the stairs or hallway can feel like threading a needle with a concrete slab.
Zonzini built the Skipper Plasmoid to solve exactly this.
Meet the Skipper Plasmoid: Built for the long (and tall) haul
Zonzini’s Skipper Plasmoid is more than an electric stair climbing dolly. It’s the only one on the market designed specifically for tall, oversized loads. And if you’re in Canada looking for an electric stair climbing dolly supplier that understands local conditions and safety standards, Movex Innovation brings that capability closer to home.
What makes the Skipper Plasmoid different?
Its tracks give it unmatched agility, allowing it to rotate 360 degrees on both indoor surfaces (such as polished hardwood) and outdoor terrains (including gravel, concrete, and stairs under construction). This agility lets your crew reposition even the bulkiest object mid-staircase or hallway.
Another advantage? Its low-ceiling maneuverability. Most stair climbing dollies require tall objects to stay vertical. Not the Skipper Plasmoid. It allows you to move material parallel to the ground, making it perfect for constrained areas where vertical clearance isn’t an option.
Use Case: Doors and windows that can’t wait
Many material handling operations are concerned with moving windows and doors. The weight and fragility are always top of mind. One wrong bump and you’re not just dealing with scratched paint, you’re dealing with shattered glass, insurance claims, an irate customer, and a bad day all around.
As a high-quality electric stair climbing dolly, Skipper Plasmoid lets your staff transport these items with the kind of control that simply doesn’t exist with manual stair climbing dollies.
Whether it’s a security door for a commercial space or a fragile triple-pane glass insert for a high-end condo, the Skipper Plasmoid offers the support and stability you need to get it from truck to install location, without white-knuckling every step of the way.

Not Just for Installers: Think Bigger
Yes, the Skipper Plasmoid was born for tall furniture, windows, and doors. But its real power lies in versatility. It’s become the go-to electric stair climbing dolly for:
- Fire extinguisher cylinders
- Server and switchboards
- Electrical panels and server racks
- Kitchen countertops
- Heavy-duty bookcases
- Large-format art installations
- Marble slabs
Basically, anything awkward, long, fragile, or tall (and often all four).
What Makes It Automatic?
The Skipper Plasmoid is what the market calls an automatic stair climbing dolly. It’s a real motorized solution with smart weight distribution. That means less lifting, less balancing, and less guessing.
Rather than manually adjusting your grip or calling for extra hands halfway through a climb, the Skipper Plasmoid does the thinking for you. As mentioned before, the tracks move independently to adapt to the shape of the stairs, while the load remains perfectly aligned.
Skipper Plasmoid vs Domino Plasmoid: Know the Difference
Zonzini also makes the Domino Plasmoid Stabilized, another electric stair climbing dolly. But if you’re deciding between the two, here’s the golden rule:
The Domino Plasmoid is ideal for shorter, bulkier loads that can stay upright. It is a go-to piece of material handling equipment for loads under 74 inches and with a low center of gravity.
The Skipper Plasmoid is your go-to solution for moving tall, narrow, or high-center-of-gravity items through tight spaces.
As we pinpointed before, if you’re transporting something over 6 feet tall or an item that needs to pass horizontally through a hallway or doorway, the Domino Plasmoid is not your best option. This is Skipper Plasmoid territory.
Stair Climbing Dollies: You Have No Competition
Let’s be clear. If you’re bidding on a job and the other guy shows up with a traditional dolly and an extra crew member, and you’ve got the Skipper Plasmoid, you’re not in the same league.
There is no alternative on the market for hauling tall objects on stairs. Zonzini’s automatic stair climbing dolly is the only one purpose-built for these scenarios.
That means faster moves, fewer accidents, less risk to property, and more profitable jobs, particularly when labour costs are high and time is tight.
Movex Innovation’s TT-66: When You’re Not Only on Stairs
Sometimes the problem isn’t stairs—it’s what happens before or after.
Movex Innovation’s own TT-66, a compact and tracked urban carrier, is designed for moving heavy loads across flat surfaces or uneven ground. It’s a perfect complement to the Skipper. Think of it as the horizontal muscle: rolling heavy items from the truck to the door, through mud, snow, sand, or gravel. The TT-66 also delivers impressive performance, effortlessly moving loads of up to 1,700 pounds up and down staircases.
Together, the TT-66 and Skipper Plasmoid cover the full spectrum of material handling problems. TT-66 gets you to the building. The Skipper Plasmoid gets you inside and up. It’s a complete workflow, not just a one-trick machine.
The right stair climbing dolly for your needs
When the job calls for more than muscle—when precision, height, and safety are non-negotiable—the Skipper Plasmoid delivers. Don’t wrestle with gear that wasn’t built for the task. Tackle your next tall order with the only stair climbing dolly that’s actually designed for it.
