Weihua made a 350t bridge crane for steel plant was shipping to the project site. The image shows the 9 large transport vehicles loaded with huge overhead cranes and accessories drove out of Weihua Intelligent Industrial Park in a mighty manner to the client's site.
The 350t casting bridge crane in this project is designed with a span of 37 meters with a 4-beam 6-track double-trolley structure. The main hoisting reducer is integrated with the frame. The manufacturing process of overall annealing and overall processing ensures the installation accuracy of gears, bearings, motors, brakes, etc. making the crane run more stably.
At present, the crane of this project have been sent to the customer's site one after another. The high-quality products and services will help the customer's project construction, and will once again demonstrate the outstanding strength of Weihua products in the large-tonnage metallurgical crane market.
Recently, Weihua successfully completed the lifting of a 450t shipbuilding gantry crane designed and manufactured for Wuhu Shipyard. The span of this crane is 92m, with a rated lifting weight of 450t and a rated turning weight of 300t. It is mainly used for turning and closing operations of the ship's hull. It has functions such as lifting, lifting, and turning over in sections in the air.
1. During the design, software (ANSYS) is used to simulate and analyze various usage conditions of the product, adjust the bearing stress, and make the product have wind resistance, earthquake resistance, collision resistance, and anti overturning capabilities.
2. The lifting drum adopts a double-layer parallel winding structure and is equipped with a rope guide to prevent the steel wire rope from jumping due to excessive deviation during lifting, ensuring safe operation.
3. Each institution adopts a variable frequency electrical control system, which has functions of load balancing, high-precision positioning, and automatic correction of supporting legs. It can achieve slow and fast operation under full load and light load, effectively solving the problem of safe switching between multiple lifting hooks lifting simultaneously and independent lifting of a single hook.
4. Equipped with a safety monitoring system, equipped with various functions such as task and operational parameter management, status monitoring, recording, tracing, alarm information sound, image display, etc.
5. The gantry crane is equipped with elevators and emergency walkways, and drivers and maintenance personnel can reach the driver's cab, high and low control rooms, and the upper part of the main beam through escalators or elevators, making it convenient for entry and exit.
This bridge crane is a capacity 500 tons 4-girder 6-Rail Metallurgical Crane independently developed by Weihua Crane. This time, only the main structure of this crane was delivered to a large steel company with steel production capacity reaching 6.5 million tons.
Features
It adopts strict and high-standard full-process control, overall processing of large structural parts, overall annealing treatment of the main trolley frame and the heavy-duty gearbox, and the overall assembly, thus the equipment stability is higher.
The electrical system uses advanced energy feedback technology, and the power generated by heavy machine loads is reused, which has greatly improved the energy utilization rate of equipment.
Recently, Weihua made a 500t gantry crane for a heave equipment company and this crane has successfully passed the acceptance inspection, adding a new member to the Weihua Large Tonnage Product List.
This product is mainly used for large-scale equipment lifting and the Max. 500t objects can be easily lifted. The span is 40m, and the lifting height is 40m, which means that the objects can be lifted to a height of about 14 floors.
1. Gantry structure adopts the lightweight design of equal strength, and the product has sufficient stiffness and overall stability, with wind resistance, earthquake resistance, and anti overturning capabilities.
2. Each mechanism adopts frequency conversion+PLC control to achieve slow and fast operation under full load and light load. It is equipped with a safety monitoring system and has functions such as task management, status monitoring, recording, storage, browsing, and tracing.
3. Multiple lifting points are combined for lifting, achieving high-precision synchronization, and equipped with upper and lower electrical deviation correction devices to ensure synchronous operation of both sides of the crane.
Carrying out heavy load operations in an outdoor working environment places higher demands on the stable operation, efficient and reliable use characteristics of equipment, and this company is located in the coastal area frequently affected by adverse weather such as typhoons. With excellent product quality and ingenious service guarantee, Weihua has built a strong safety fortress for customers. Its products can withstand typhoons of magnitude 12 and earthquakes of magnitude 7, eliminating worries for customers.
Weihua made anautomated bridge crane for electrolytic copper industryin Guangdong, China. The highlight of this crane is the special lifting spreader which is used for the automatic discharge and loading of cathode (starting plate) and anode plate. It has the advantages of multiple functions, high automation, reliable insulation, stable performance, etc.
The crane spreader is independently developed by Weihua. Its main structure is made of high-quality stainless steel, with high strength, acid corrosion resistance, excellent quality and greatly reduced cost. It is really the best choice for users to reduce costs and increase efficiency. In addition, the spreader also has the following features:
1. Specially designed plate arrangement function and discharging device ensure that the initial cathode plate can be smoothly put into the tank;
2. It can meet the requirements of separate lifting and overall joint lifting of cathode plate and anode plate, with high efficiency;
3. The method of combining pre positioning with precision positioning is adopted, and the positioning accuracy is ± 2mm;
4. The opening and closing of the flat push type liquid receiving tray are stable to ensure that the electrolyte does not splash out.
Weihua has strong processing equipment. Only with strong processing capacity can it meet the complex processing needs of special lifting appliances for copper electrolysis.
There are many highlights in the design of spreader, and the comprehensive design of the main crane is also a masterpiece. It is equipped with a fully automatic operation system, with high operation efficiency, convenient operation and advanced performance.
1. The bridge crane has 3 operation modes: fully automatic, semi-automatic and manual;
2. The bridge crane adopts frequency conversion and PLC precise control, with high-precision positioning;
