The important machinery and equipment structure of the terminal crane: 2 main beams, 1 crane truck, 1 grab bucket, 1 set of operating room, 1 set of cable and electrical equipment and spare parts.
1. Main beam assembly. Sort out the location, and then use wooden sleepers to separate them and place them on both sides of the main beam. Place the two main beams in the door crane in order and place them forward. Use a manual hoist to bring the two main beams close to each other, and use a hydraulic jack to lift the two main beams. The main beams are paved and then connected with main beam connecting plates and anchor bolts. The connecting plate is fabricated during the main beam manufacturing process, and the anchor bolts are high wear-resistant pin-shaft anchor bolts.
2. Machinery equipment operating room and electrical products part. After the main beam is assembled, fix the surrounding guardrails, use a crane to tie the main beam of the dock crane to a height of 1m, fix the operating room on the bracket with anchor bolts, and hoist it together with the main beam.
3. Try lifting the main beam. The hoisting of the main beam is completed by a 50t crane alone to check the balance and stability. The inclination angle below the main beam and the point where the galvanized steel wire is installed must have a circular holding angle to avoid damage to the galvanized steel wire.
4. Hoist the main beam. After the test hoisting check is correct, prepare to officially announce the hoisting. The hoisting will be guided by a crane. During the hoisting, the hoisting operator will only follow the signal of the hoist, regardless of the continuous signal issued by everyone to stop. When hoisting the main beam to a height of 500mm above the rail surface, use control ropes on both sides to rotate the main beam to a certain angle. After accurate measurement and positioning, learn to abandon the main beam and loosen the lifting rope.
5. Hoisting crane truck. After the main beam is hoisted, use a crane to tie up the crane truck and place it in the measured position on the main beam so that the four wheels are in contact with the guide rails on the main beam. At this time, it is necessary to tighten the brakes to prevent the crane truck from rolling away.
6. Grab equipment. After the main beam is energized and adjusted, everything is working normally. After each limit switch and limit switch are comfortable and reliable, learn to abandon the galvanized steel wire, string the grab according to the Cantonese, and adjust it.
