AXLE JACK - 65 TON (T-type with air pump) Operating instruction Foreword Our company is a designated manufacturer of aircraft ground equipment for major airlines in the country, and has more than 20 engineers and researchers who have been engaged in the development of ground equipment for more than 20 years. The company has recently launched a new type of aircraft axle jack, which changed the phenomenon of internal leakage caused by the previously used reversing valve, which could not keep the pressure, and the operation was simpler, reaching or even exceeding the level of similar products in the world. It is well received by the majority of civil aviation users. Ⅰ. Product Features 1. The product adopts two-way hydraulic oil circuit, which does not require the old-fashioned reversing. It can be lifted and lowered only by turning the handle. 2. The heavy-duty walking wheel is adopted, and the plate spring is used for shock absorption, which makes the whole equipment move flexibly and is easy to use. 3. The surface of the oil cylinder, piston and adjusting screw are all treated with high hardness and corrosion-resistant materials. in order to increase the service life of the product. 4. The heavy-duty walking wheel is adopted, and the plate spring is used for shock absorption, which makes the whole equipment move flexibly and is convenient to use. Ⅱ. The scope and purpose of the product This product is one of the most ideal lifting tools for wheel replacement in major, medium and small airports and air force airports in the country, with a lifting capacity ranging from 30t to 100t. This product is mainly used for lifting the nose wheel and main wheel of Boeing series, McDonnell Douglas series, Airbus series and other new passenger aircraft

AXLE JACK - 65 TON (T-type with air pump) Operating instruction before operation Every time the jack is used, it must be checked carefully 1. Check whether the hydraulic oil in the tank is sufficient, and the liquid level must reach the tank 4/5 of the height. If insufficient, please add 10# or 15# aviation hydraulic oil. 2. Check whether the surface of the hydraulic cylinder is damaged, and the hydraulic pipeline and pipe joint are whether there is seepage, oil leakage. 3, check whether the manual pump and pneumatic pump work normally. When all is well can operate. Ⅵ. Operation 1. Lifting:...
