【Massive 77,000 LBS Lifting Capacity】 Engineered for heavy-duty trucks, tractors, and industrial equipment, this 35-ton hydraulic floor jack delivers professional-grade power. Its reinforced steel construction ensures reliable, long-lasting performance in demanding shop environments. 【Low Profile Design with Secure Adapters】 Featuring a low 10-inch saddle height, this jack easily fits under lifted trucks and lowered cars. Four included adapters (10/25/60/100mm) provide stable contact points for uneven frames and specialty vehicles, preventing slippage during operation. 【Adjustable Handle & Workshop Mobility】 The 46-inch handle adjusts and pivots 90-180 degrees for precise control in tight spaces. Eight-inch rubber wheels offer superior traction and smooth rolling on rough, oily, or uneven workshop floors. 【Built-In Safety Protection System】 An integrated overload protection valve prevents sudden release under excess weight. The non-slip steel base and durable locking wheels ensure maximum stability on uneven surfaces, prioritizing accident-free operation. 【Dual-Power Air & Manual Operation】 Connect to any air compressor (90-145 PSI) for fast, effortless lifting. The manual hydraulic backup system guarantees reliable operation when air is unavailable, making this the most versatile heavy-duty jack for any professional situation.
