Are you sure it's okay to lose a leg on a pump job?

  Pump truck frame in the cement floor, and only half of the legs dare to lie forward, the courage is too big! No accident is a story. An accident is an accident! But this situation is not uncommon, due to site restrictions, many times with a fluke mentality, although dangerous, but also hard on the scalp

  Notes for unilateral support

  1. one-sided braces should only be used if all legs are not fully extended. Full braces are recommended most of the time. For pumping concrete vertically upward, the use of unilateral support is prohibited.

  2, the choice of one-side support support site, also need to be strong, flat ground, it is best to be able to put some wooden squares under the outrigger, increase the contact area, to prevent the collapse of the outrigger. At the same time, unilateral support, the outrigger must be fully extended to its limit position, until unable to move so far.

  3. In the case of front support, when the jib is deployed, first extend one arm to the vertical position, then rotate the jib to the front of the working range, and then expand the other jib. Remember not to spread out all the arms and then rotate all at once, there is a risk of roll.

  4. In the case of left and right support, if it is left support, after one arm is deployed, don't be in a hurry to deploy other arm frames either. First rotate the whole arm frame to the left side of the car body to the working range, and then deploy the other arm frames, the right support and the left support operate in the same way, in the opposite direction.

  5. Each brand of one-side support, in the pump truck operating system, also have the corresponding one-side support options, after the outrigger fully deployed into one-side support, it is also necessary to select your current support mode in the control system to ensure that the limit sensor is working properly, so that there is no need to worry about excessive arm rotation. At the same time, the working process, the prohibition of modifying the pump truck support mode.

  6. For the old-style pump truck without rotary limit function, try not to choose one-side support, in order to avoid out of the working angle range of the boom and lead to the risk of overturning the pump truck.

  7. After the work is finished, it is forbidden to change the support mode in the control system of the pump truck if the boom is not completely closed.

  Different brands of boom pump truck, the scope of its work may be different, so, in the use of time need to see the use of instructions.
