This heavy-duty floor jack is engineered for maximum performance and ease of use. Constructed from durable Q235 steel, it reliably supports substantial loads up to 18,000 lbs (8,164.66 kg), making it perfect for critical lifting tasks. Its key feature is the broad adjustable height range, allowing positioning from 56 inches (142.24 cm) to 100 inches (254 cm) to suit diverse project requirements. Adjusting the height is remarkably simple and tool-free, accomplished just by rotating the integrated lever. For enhanced safety during operation, two lock pins are included to securely hold the jack at the chosen height. The integrated welded base plate is seamlessly fused to the pipe, providing inherent strength and stability without the need for assembly bolts or separate fixation during installation. This robust and versatile support solution is ideally suited for temporary applications in construction, renovations, and structural support tasks involving beams, decks, patios, and similar structures.
