2. Work a. When the class first lifting weights (or the maximum load weight) for gantry crane at ground level should be 0.5 meters hanging from the rear, the weight is lowered again 100 tons gantry crane, check brake performance, reliable after confirmation, then for normal operation. b. Strict implementation of "Ten is not hanging" system: ① command signal is unknown or not hanging chaos command; ② when not hanging over the rated capacity; ③ spreaders unreasonable or unsound not hanging objects hanging bundles; ④ hanging objects on someone or There are other items are not hanging unanchored; ⑤ brake or other brake safety device failure not hang; ⑥ driving when not hanging heavy hanging directly processed; ⑦ pull Xiegua not hang crooked; ⑧ explosive objects do not hang; ⑨ do not hang objects buried in the ground; ⑩ angular block port objects, not really hang pad; c. Abnormal gantry crane, gantry crane hanging down immediately, turn off the power, check the reason and immediately removed. Third, to determine the principles wheelbase of (a) meet the requirements of the stability of the gantry crane along the track direction; (b) the overall dimensions to be able to pass the legs flat steel; (c) pay attention to the tread B and span S proportional relationship, and generally Wheelbase B = (1 / 4-1 / 6) S. Fourth, the gantry crane pitch size determined in the work, should be left between the external dimensions of gantry cranes and container yard cargo and transport vehicles passage certain spatial dimensions, in order to facilitate loading and unloading operations. When the general transport vehicle loading and unloading in the span, and doors should be kept above the legs have 0.7m spacing. Spreader should not work more than 0.5m spacing and transport vehicles, cargo when the legs get married, there should be more than 0.5m spacing.
