PRODUCTS & CASES

This tailor-made overhead crane is purpose-built to support polypropylene reactor production and assembly tasks. The finished reactor unit weighs as much as 1,500 tons, assembled from 12 core pipeline sections and six bending components. These customized cranes can hoist separate single segments independently, and multiple units can run synchronously to complete the integrated lifting of the full reactor assembly.

Mechanical Strengths

1. Optimized lightweight structural layout delivers multiple merits including light self-weight, minimized wheel pressure, low overall crane height and reduced power consumption. It achieves shock-free steady circulation with ultra-low operating noise.

2. Each crane is equipped with a dedicated electronic weighing module that keeps measurement error below 3‰. This design overcomes common industry pain points such as difficult sensor installation and unstable weighing precision on standard lifting machinery.

3. The winch trolley’s hoisting assembly adopts a statically determinate force-bearing framework. Hoisting and travel driving parts integrate gear reducers, driving motors and braking units into one fixed three-point positioning assembly.

4. A full-set electric centralized lubrication system is deployed across all moving parts of the crane. Automatic regular oil supply cuts manual labor expenses and prevents oil leakage contamination on workpieces and factory floors.

Weihua full-series overhead cranes are extensively adopted in mechanical processing, metallurgical smelting, power generation, railway transport, port logistics, petroleum exploitation and chemical manufacturing sectors. Our lifting equipment has supported numerous national key construction projects and production bases of large industrial groups.

1. 1. Equipped with Weihua self-developed anti-sway algorithm, the system supports coordinated synchronous lifting of several cranes, enabling ultra-precise and vibration-free load movement.

2. 2. Adopts stable wireless data communication to realize multi-crane linkage operation, which can adapt to varied lifting plans for different pressure vessel workpieces.

3. 3. Absolute encoders provide real-time position feedback while laser ranging devices guarantee synchronous coordination between multiple cranes. Customized program algorithms realize millimeter-level precise motion control.

4. 4. Built-in integrated crane management platform supports real-time fault alert, historical operation log retrieval and running status data analysis for convenient equipment maintenance.

Weihua Crane delivers fully personalized overhead crane solutions dedicated to petrochemical factories, chemical workshops and nuclear power plant construction sites. Featuring powerful load capacity and pinpoint handling accuracy, these custom cranes maintain stable performance during transportation and assembly of reactor tubes and heavy pressure vessel parts.

All core technical indicators including lifting tonnage, working span, vertical lifting height and track width can be adjusted flexibly to match diverse plant layouts and heavy equipment lifting standards, supporting consistent efficient and risk-free daily operation.
