OY4502 Standard 3Ton Air Jack

The Standard 3Ton Air Jack is the baseline model of the air jack series, providing a reliable combination of 3-ton lifting capacity and 400 mm maximum lift height in a straightforward, uncomplicated format. Its single-configuration design makes it the most widely used model in the range, suitable for general automotive workshops, tire centers, and mobile breakdown services.

The pneumatic bag assembly is constructed from reinforced rubber compound that retains flexibility at low temperatures, allowing the jack to function reliably in outdoor winter environments where cold-hardened rubber on cheaper units would crack or lose elasticity. This cold-weather performance is a practical differentiator for facilities in northern climates.

Air inlet connection uses a standard 1/4-inch push-fit coupling that connects instantly to any shop air line or portable inflator. The internal valve allows one-handed operation—pressing the trigger inflates, releasing it holds position, and a separate dump valve controls lowering. This simple interface reduces operator training time to near zero.

The base plate is fitted with a shallow peripheral lip that prevents the jack from sliding on smooth or slightly oily floor surfaces during the initial inflation phase when the bag first contacts the vehicle and load begins to transfer. This anti-slip geometry is a subtle but effective safety feature.

At 19 kg gross weight, the OY4502 is portable enough for one person to carry to and from a vehicle and position beneath the jacking point without assistance—an important practical consideration for emergency roadside use and single-technician operations.
