1, the crane's hydraulic outrigger should be four horizontal outrigger production fixed sheath pull out, put the outrigger before the tightening of the stabilizer, such as liquid, and then quickly compound the handle to the middle position, and then in the crane under the four vertical legs put a good cushion wood, the vertical outrigger manipulation handle to the "reach" direction of the production of the wrench, then the four vertical outriggers together with the outreach.
2, at this time should pay attention to observe when the rear axle tires are off the ground immediately after stopping the operation, if the tilt is too large, manipulate the rotary valve to make the twisting and vertical outrigger handle alone to manipulate the vertical outrigger in the low position of the production of the vertical outrigger hydraulic cylinder to continue to lift, until the whole machine leveling until.
3, the whole machine leveling is completed, the rotary valve pressure pump after idling, the crane operation is over or need to move the site, should be the contraction of the lifting arm falls on the bracket, and then the rotary valve switch pointing to the full position of the vertical outrigger hydraulic cylinder retracted, the middle and rear axle tires fall to the ground; and then to the collection of the production of direction to promote the horizontal leg manipulation handle, then the four horizontal legs at the same time closed, and finally the four horizontal leg fixed Finally, insert the four horizontal outriggers into the sheath, and point the rotary valve rotary switch to the fully closed position.
