1200/1250t special crane and key technologies

Verify the technical performance and reliability of crane: 9.1 Test method using single-strand rope, hoisting mechanism and verify the reliability of the safety brake. 9.2 verify the reliability of the bridge, including (1) to verify design reliability and (2) the reliability of materials and manufacturing of two parts. In which the reliability of the materials and manufacturing company materials used by the test, major bridge NDT weld 100 for authentication, and through quality assurance system and to invite representatives of the buyer guaranteed spot verification. The reliability of the verification for the design, the use of our company in the \safety and reliability of lifting full load. When the bridge in any position to bear any load,[link widoczny dla zalogowanych], the system can calculate the real-time load in the group designated under the stress and deflection values set position theoretical value, while real-time measure of the actual stress point and the location of the actual deflection values,[link widoczny dla zalogowanych], and compared with the theoretical calculation, if the deviation of the difference are within the system and the corresponding linear relationship between, you can verify the design calculations are reliable. Lifting heavy objects, the \In the first full load lifting work, but also will work in conditions of security measures, slightly lifted off the ground again after using the system to verify the above two load test,[link widoczny dla zalogowanych], you can be assured to ensure a reliable lifting over the premise load. l0. 1200t security measures to ensure the safe operation of crane, in addition to the above described set of security measures and some general security measures, also set the following security measures:. 10.1 In addition to the main lifting mechanism motor in each set two high-speed shaft brake hydraulic plunger,[link widoczny dla zalogowanych], the flange on the drum set in the safety brake at the same time have a detection system should be associated with. When the transmission of a link failure, the control system immediately brake safety brake control to ensure that the suspended load will not fall because of an accident. And wire rope reel under 10.2 in the balance arm to set a security bracket bracket, when the volume and balance of short-axis arm accidentally broken, the security support can play a supporting role. 10.3 In the reel wire type of wire rope clips with combined fixed plate in the direction of the oblique wedge-shaped groove, the two bolts through the mounting bracket plate tightly pressed plate, due to the role of wedge-shaped groove, keeps getting tight. 10.4 The main lifting gear and the reel with a ball hinge between the drum coupling, transmission torque, allowing the axis of the deflection angle, can well compensate for the small frame deformation and installation errors, and to Assembly and Disassembly reel becomes much convenient. Frame and balanced wheel balance 10.5 are equipped with safety outrigger boom, car axle in the accident state to play a supportive role. 10.6 rims traveling mechanism in addition to other guidance, also set on the electrical correction and synchronization measures. 10.7 When two cranes and truck cranes lift rotor, in order to ensure that the level of balance beam without deflection, set the balance beam correction device, ensure the balance beam at both ends of the level of poor control in less than 50mm from 10.8 in 1200t l institutions and 125t, respectively hoisting mechanism is set to 2 and 5% accuracy of the electronic weighing system, which on the one hand played a role overload limiter, when the rated lifting load from the weight of the 90 Heda, can issue an indicative alarm signal; when lifting the rated lifting load Heda cricket, the issue of full alarm signal; when the rated lifting load from the weight of Heda 105, the delay down; when lifting the weight set Heda I10% rated, immediately cut off Lifting power supply and a prohibition of the alarm signal. 10.9 Crane run institutions and the main car body,[link widoczny dla zalogowanych], set the precision of ± 10mm of the two-dimensional positioning device, lifting mechanism in the altitude display on the set, hanging position to make accurate and controllable, and in accordance with the pre- The location of lifting operations, easy and accurate installation of equipment in place. 10.10 set real strength and stiffness of the main beam on the detection and monitoring system, real-time detection and display of strength and stiffness of the main beam, and a standard before the alarm, the excessive power parking feature. 10.11 has a bridge crane in the drivers room display system status and fault can be run on a variety of signals, protect the signal, detecting the signal, fault signal integrated display. Operator of the equipment operation at a glance. 10.6 ~ 10.10 10.12 collected for the signal and the main beam strength and stiffness of real-time detection and monitoring system, we designed a set of integrated information management and control system software, in windows95 and (continued on page 57)
