Mobile lift itself with heavy load handling, self-propelled, flexible, high stability and high through the unique advantages, so how to achieve these characteristics? To look down, then lift platform should not be whole lifting action is on the platform of mobile, put down the four security under the condition of leg, at the same time, through to lift hydraulic system has realized the oblique line, transverse, eight steering pendulum is head and tail, center, and other rotary steering model, also meet other support under different road conditions and different load working condition operation state.
That is to say, when the rubber inflatable tire of the lift is steering, because the tire contact with the ground is different, each steering wheel group is subjected to a different load, resulting in the control of the hydraulic cylinder working pressure is not the same. In the process of elevator steering, all wheels must have the corresponding coordination, to avoid causing tire wear and steering in the process of walking instability. Mobile lift design principle is in addition to satisfy the structural strength of the parts, and ensure that all the action of the hydraulic oil cylinder synchronization, so in addition to providing platform for hydraulic lifting and leveling function, more important is the plunger telescopic compensation function to ensure the carrying capacity of the wheelset evenly, during the operation of skid prevention, can adapt to the uneven road surface, keep safe and reliable operation.
