One Person. One Desk Lift. Zero Back Strain.
The Mighty King™ 4000 Series is the extra heavy-duty desk lift that lets one person safely lift and move desks, file cabinets, bookcases, and office furniture weighing up to 600 lbs. The largest 4-inch non-marring swivel casters in the Mighty King lineup glide over thick carpet, tile, thresholds, and uneven warehouse floors—no dragging, no scraping, no damage.
Slide the lift frame under the furniture, pump the hydraulic handle, and roll. That’s it. What used to take a crew of three now takes one person and a Mighty King. Available in 32", 40", and 46" widths to fit desks of all sizes. American-made in Minneapolis since 1958.

Which width do you need? Measure the inside width of the desk’s leg opening. The lift frame must fit between the legs. For standard classroom desks (30" wide), the 32" model works perfectly. For executive desks and L-shaped workstations, choose 40" or 46".

All three series share the same 600 lb. capacity and hydraulic pump mechanism. The difference is in the casters: larger casters roll easier over rough surfaces. If your facility has thick carpet, uneven floors, or door thresholds, the 4000 Series is the right choice.

Frequently Asked Questions
Will the casters mark my floors?
No. The 4-inch casters are specifically designed to be non-marring. They won’t scratch hardwood, scuff tile, or leave marks on polished concrete. Safe for gym floors, too.
What’s the heaviest thing it can lift?
600 lbs. That covers virtually any desk, file cabinet, bookcase, safe, or piece of office furniture. The hydraulic pump makes lifting effortless regardless of weight.
How do I choose between the 2000, 3500, and 4000?
It comes down to your floors. Hard, smooth floors? The 2000 is fine. Mixed surfaces with some carpet? Go 3500. Thick carpet, rough concrete, or lots of door thresholds? The 4000’s 4-inch casters are the only choice.
Can one person really move a 600 lb. desk alone?
Yes. That’s the whole point of the Mighty King. The hydraulic pump lifts the load, and the swivel casters let you steer it anywhere. Schools across the country use these every day—one custodian, one lift, zero back injuries.

Yes. Contact us directly for volume pricing on orders of 5 or more units. Factory-direct pricing means no middleman markup.
