Hand-Cranked Gear Type Screw Mechanical Jack  Introduction
Designed to address the demand for safe, efficient manual lifting, our gear type screw mechanical jack integrates a rugged gear transmission system with a high-strength screw rod to deliver consistent performance. The one-piece cast steel body and precision-machined components ensure structural integrity and resistance to wear, even under repeated heavy loads. A built-in red limit line provides visual safety warnings to prevent over-lifting, while the ergonomic portable handle enables easy transportation between work sites. Whether you need to lift vehicles, align machinery, or position heavy materials, this jack’s flexible height adjustment (from 117MM to 255MM of net lift) and stable base design ensure reliable operation, reducing manual labor intensity and improving work efficiency.
