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 been awarded the title of "Single Champion Demonstration Enterprise in Manufacturing Industry".

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%, and can create greater value for customers without raising costs. Chinese bridge crane projects have blossomed everywhere

let's take a look

01 Rugao Hongmao Cast Steel Project

● Weihua provided two 500t overhead cranes for Rugao Hongmao Casting Steel Project, and innovatively proposed a dual-mechanism hoisting scheme.

● 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 variable frequency speed regulation, with wide speed regulation range, stable braking and small mechanical impact. The cart adopts 8-wheel structure, which can effectively reduce the wheel pressure of cranes.

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 the safe and reliable material handling work of the equipment.

● The product adopts the structure of double-beam, double-track, and single-hoisting trolley. All 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 the new Chinese-style structure, reasonable drum diameter, pulley set magnification and reducer support structure, so that the hook operation service surface of this 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-scale 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 rail and the three fulcrums. The occurrence, the manufacture is fine, and the appearance is beautiful.

05 Jiangyin Jintong Petrochemical Project

● The product specification is 200t/50t, the main girder adopts off-track box girder, and the section is calculated by finite element force analysis. 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.

Weihua new overhead bridge crane features:

Compared with ordinary products, Weihua's new bridge crane can reduce its own weight by 25%, wheel pressure by 20%, and its own height by 30%;

Guided by modular design theory and direct visualization technology as a means, introduce optimal design and reliability design methods;

The new concept bridge crane completed with new materials and new technology has the characteristics of high generalization, intelligence and high technology content, and has the advantages of low energy consumption, durability, high reliability, and convenient automatic expansion in the later stage.
