Frequently Asked Questions
How does this compare to Harbor Freight trolley jacks?
The ESCO 90521 offers professional-grade construction and precision control that budget alternatives can't match. The dual-piston system lifts faster, the lift & twist lowering provides better control, and the ASME certification ensures safety standards that cheaper jacks often lack. While Harbor Freight jacks work for occasional use, this ESCO model is built for daily shop use and demanding applications.
What's the difference between a trolley jack and floor jack?
Trolley jack and floor jack refer to the same type of hydraulic lifting equipment. Both terms describe wheeled jacks that roll along the ground, as opposed to bottle jacks or scissor jacks. The ESCO 90521 is designed as a professional trolley/floor jack with heavy-duty wheels for easy positioning.
Will this work with low profile cars?
Yes, the 3.75" minimum height makes this one of the lowest profile trolley jacks available. It easily fits under sports cars, lowered vehicles, and other cars with minimal ground clearance where standard jacks won't fit.
Is this suitable for trucks and SUVs?
Absolutely. With a 3-ton (6,000 lb) capacity and 19.69" maximum lift height, this jack handles most pickup trucks, SUVs, and commercial vans safely. The robust construction and precise control make it ideal for heavier vehicle service work.
Warranty Coverage
This professional trolley jack includes a 1-year limited warranty covering manufacturing defects and material failures under normal use. ESCO's warranty reflects their confidence in the quality and durability that professionals expect from their lifting equipment.
