Double-column lift is a double-column car lift car repair and maintenance units commonly used special machinery lifting equipment, widely used in cars and other small vehicles Fixed lifting platforms (Car Lift) repair and maintenance . Double-column car lift car lift in the air at the same time can save a lot of floor space, easy ground handling. But the double-column vehicle lift for maximum material savings are generally removed the floor. With no floor, so the column need to rely on the ground to counteract the torque, so the foundation is demanding, if there is beam (Gantry Lift) to offset against the crossbar. Double-column lift has symmetric and asymmetric two. Symmetric lift arm length is approximately equal to the four-arm lift four tons, which makes the car center (or centroid) lift in the middle of the column, for routine maintenance pickups and vans and other types of vehicles to This symmetry Lift say may be the best choice. But among some of the column is not wide enough for large symmetric double-column lift, the lift can not open the door after the car is a big drawback. Asymmetric lift uprights backward rotation of an angle (about 30 °), and the forearm is slightly shorter than some of the rear arm. When the car park to lift such a non-symmetrical position, the position of the car to move backward some, therefore, we would be very easy to access from the door. Moreover, this rotation asymmetric lift uprights, the center of gravity of the vehicle can ensure safety positioned between the uprights. Car lift in preparation before use, when the lift car should pay attention, the stability of a large lift bearer, cautions car when lowered, routine and periodic maintenance inspection report work. Although the car lift more than 70 years of history lifts, its design principle has not changed much; but if the beam neglect safety requirements. Overload use negligence, would still cause a serious accident, or even injury or death. So the problem must be caused by the use of security units and operating personnel are highly valued. First, should buy those good safety performance of the car lifts, in addition should also seriously study and understand the safety precautions automotive lifts and seriously cut consistently perform here only for cause) generally should be noted that the lift maintenance Matters are discussed herein.
