OY1103 0.5Ton Heavy-Frame Transmission Jack

The OY1103 is a 0.5‑ton heavy‑frame transmission jack, purpose‑built for professional automotive repair facilities, truck service centers, and industrial maintenance shops that require exceptional structural rigidity and stability when handling transmissions, transfer cases, and differentials. With a maximum lifting capacity of 0.5 tons, this jack safely handles passenger car transmissions, light truck transmissions, and heavy transaxles. The defining characteristic of the OY1103 is its heavy‑frame construction: the chassis and mast are fabricated from thicker‑gauge welded steel than standard jacks, with additional cross‑bracing and reinforced gussets at all critical stress points. This results in significantly reduced flex and deflection during lifting and lowering, providing a more stable platform for aligning heavy or awkwardly shaped loads.
The hydraulic system includes a built‑in overload valve to prevent exceeding the rated capacity, a precision release valve for controlled gradual lowering, and a safety valve to prevent sudden drop in case of hydraulic failure. The heavy frame also provides a lower center of gravity, improving stability when the load is raised to its maximum height.
The lifting height range (typically 850 mm to 1835 mm) accommodates most service applications. All wear parts, including casters and hydraulic seals, are selected for long service life under heavy use. The jack is finished with a durable powder coating that resists oil, grease, rust, and shop abrasion. Net weight is approximately 74 kg, reflecting the heavier construction.
