1. From the design structure:
1 European-style crane: The main beam adopts box-type beam structure, the structure is reasonable and the strength is higher. The hoist is firmly combined with the lower flange of the main beam, no hidden danger, increasing the effective lifting height, thus improving the effective working space and the largest clearance difference. , up to 1.5 meters, the wheel pressure is reduced, the bearing beam is reduced;
2 Traditional crane: limited by the design of the hoist, only the traditional under-beam I-beam structure can be used. The structure is unreasonable and the utilization rate is low. The combination of the hoist and the lower flange of the main beam leads to a high incidence of detachment accidents.
2, from the appearance:
1 European-style crane: light and beautiful appearance, in line with the modern industrial aesthetic, effectively use the plant space, the limit distance of the hook to the two sides of the wall is small, the clearance height is low, the layout of the existing plant is more flexible, the new plant can be designed Smaller and more complete;
2 Traditional crane: The appearance is large, bulky, vertical, horizontal, the limit size is large, the effective working area is small, and under the same plant structure, the space utilization rate is low.
3, from the volume point of view:
1 European-style crane: the lowest clearance height, the smallest dead weight, good wind resistance, good running balance, safe and reliable;
2 Traditional crane: The amount of steel used is large, the volume is relatively large, the impact is large, and the load is shaken vigorously.
4, from the installation design:
1 European-style crane: fully enclosed design, will not rely on dust, frequency control, safer to use;
2 Traditional crane: The structure of the gearbox is open, exposed to the air, and easy to attach to dust.
5. From the perspective of operation and maintenance costs:
1 European-style crane: The whole machine has low power, low power consumption, reliable quality, low failure rate during correct use, which can minimize the loss caused by equipment failure and save equipment maintenance costs;
2Traditional crane: The power of the whole machine is large, the running cost is high, and the life of parts and components caused by the cost limitation during the use of the vehicle is short, the failure rate is high, and the production loss and maintenance replacement cost are easy to occur.
