Features: Two-girder bridge crane consists of bridge, traveling mechanism, trolley, electrical equipment and other components. Depending on the frequency of use, divided into A5, A6, A7 three operating levels. Crane manipulation action completed within the driver. Double girder overhead crane main parameters: Starting weight: 5 to 10 tons fixed crane, 16 / 3.2 ~ 50/10 tons, 75 / 20-100 / 20 t bucket crane, 100/32 t 125/30 ~ 250/50 ton, 300/40 tons, 350/75 tons, 400/80 tons, 600/150 t Span: 10.5 to 31.5 meters, 13 to 31 meters. Lifting height: 6 to 22 meters. Installation specifications: 1, trolley car at the factory have passed the test test. Therefore, in the slightly adjusted to eliminate transportation deformation after the bridge can be directly mounted on the case of compliance with the relevant technical conditions, the car may not be the case there are three legs (ie, only three car wheels in contact with the track installed in the bridge, another vacant ), otherwise, to be in the floating wheel bearing housing or the lower rail padded adjustment, the pad must be placed only when the next layer, the main beam track padded ribs at both ends of the fixed spot. ① the detection of indicators of metal structures to perform according to regulations, in order to reduce the amount of high-altitude operations, the equipment installation, wiring, etc. as far as possible on the ground. ② cranes erected before the following methods shall be installed overhead crane wholesale, if found in time to eliminate the shortcomings, such as the user can not be processed immediately and contact the manufacturer, when the crane is erected on the factory after factory and can not deal with this problem . a, the crane placed on two parallel rails at several coplanar. b, to the end of the beam bolt holes for positioning the piano accurate, according to the attached map - crane installation joints connecting the label side girder bridge crane, the crane will be combined, after appropriate adjustment tighten the bolts. After the crane assembled, the indicators should be consistent with the relevant data.
