The port crane is a kind of mechanical equipment with wide application and powerful characteristics. As the key mechanical equipment of the port, its advantage lies in the high-quality structure. Its important equipment structure is as follows: 2 main beams, 1 crane, 1 grab bucket, 1 set of operation room, 1 set of cable electrical equipment and spare parts.
1. Main beam assembly. Carding places to meet the requirements of mechanical equipment assembly. Then use wooden sleepers to separate them, pad them on both sides under the main beam, then place the two main beams in the door crane in sequence, use the manual hoist to bring the two main beams close, use the hydraulic jack to lay the two main beams, and then Connect the main beam connecting plate with the anchor bolts. The connecting plate is the configuration in the manufacturing process of the main beam, and the anchor bolts are high wear-resistant pin shaft anchor bolts.
2. Some equipment operating rooms and electrical products. After the main beam is assembled, it is fixed on the surrounding guardrail. The main beam is tied to a position of 1m high with a port crane, fixed on the bracket with anchor bolts, and hoisted together with the main beam.
3. Try hanging the main beam. The hoisting of the main beam is completed independently by a 50t crane, and a trial hoisting must be carried out. First, tie the main beam to a height of 300mm to check the balance and stability. The contact between the lower inclination angle of the main beam and the point of the galvanized steel wire should be a ring angle to prevent damage to the galvanized steel wire.
4. Hoist the main beam. After the test lifting check is accurate, prepare to release the lifting in advance. When lifting, it is guided by the lifter. Whoever issues the signal rules, only follow the hoist signal.
5. Hoist the crane truck. After the main girder is hoisted, use a port crane to tie up the crane and put it on the main girder, measure the direction accurately, and connect the four wheels with the guide rails on the main girder. At this point, tighten the brake system to prevent the crane from sliding.
6. Grab equipment. After the main beam is energized and adjusted, each distribution works normally. After each travel switch is comfortable and reliable, learn to abandon the galvanized steel wire and adjust the grab according to the extensive to ensure that the grab elevator is easy to open and close.
