Overhead cranes have always been one of Weihua's most competitive products. With the strong performance of general overhead cranes in the market, Weihua has won the title of "Single Champion Demonstration Enterprise in Manufacturing". On May 28 last year, Weihua launched a "new Chinese" crane that can reduce energy consumption, wheel pressure and its own weight by more than 20%, creating greater value for customers without increasing costs. In the first quarter of this year, new Chinese bridge crane projects have blossomed everywhere, let us have a glimpse of their style.
01.Rugao Hongmao Cast Steel Project
Weihua provided two 500T bridge cranes for Rugao Hongmao Casting Steel Project,Weihua innovatively proposed a double-mechanism hoisting scheme. The trolley adopts a one-to-one structure. Through finite element structural analysis, repeated verification and calculation, the bridge structure is selected.
The bridge crane is composed of 8 sets of large trolleys, with 32 wheels, the outermost wheel spacing is 24 meters, and the trolley adopts an extra-large 13.9-meter gauge, which well meets the customer's requirements for wheel pressure customization and workshop conditions.
02.Tsingshan Holdings Project in Indonesia
The main beam of the crane in this project adopts the design of the off-track box beam, and the whole vehicle adopts the finite element analysis and optimization design to reduce the total weight of the crane and the overall height of the crane.
The whole vehicle adopts frequency conversion speed regulation, which has wide speed regulation range, stable braking and small mechanical impact. The cart adopts 8-wheel structure, which can effectively reduce the wheel pressure of the crane.
03.Xiangyang Port Xiaohe Port Project
The whole machine is composed of bridge frame, cart running, trolley, driver's cab and electrical equipment. The equipment is equipped with various mechanism installations and various safety protection devices and alarm devices to ensure that the equipment can carry out material handling work safely and reliably.
The product adopts the structure type of double-beam double-track and single hoisting trolley. The components are compactly arranged, easy to maintain, safe and reliable, easy to operate, stable in operation and light in weight.
04.NGC Wind Power Huaian Project
The project product adopts new Chinese-style structure, reasonable drum diameter, pulley set magnification and reducer support structure, so that the hook operation service surface of the machine is significantly larger than that of ordinary bridge cranes, which improves the utilization rate of the workshop and saves a lot of civil engineering costs. At the same time, it also brings the technical indicators of the workshop into line with the international advanced level.
The main beam and the end beam are connected by bolts, the structure is reliable, and the whole machine is light in weight, which is convenient for overall transportation and on-site installation.
The trolley frame adopts a large CNC floor milling and boring machine to process the reaming holes of each support and the trolley trolley as a whole, reducing the manufacturing deviation of the riveting and welding process, with high manufacturing precision, improving the installation accuracy of each component, and avoiding the phenomenon of the trolley gnawing on the rails and the three fulcrums. Happened, finely manufactured, and beautiful in appearance.
05 .Jiangyin Jintong Petrochemical Project
The product specification is 200T/50T, the main girder adopts off-track box girder, the section is calculated by finite element force analysis, and the cart adopts trolley group to reduce wheel pressure and protect the workshop. The operation adopts three-in-one geared motor, and the failure rate is low.
The trolley adopts a one-to-one structure, which effectively reduces the weight and height of the vehicle, which reduces the requirements for the workshop. The lifting mechanism adopts a statically indeterminate structure, which effectively avoids the additional stress caused by the error of assembly accuracy.
