PRODUCTS & CASES

Weihua develops customized special cranes tailored for distinctive industrial sectors. Nuclear power overhead cranes are dedicated lifting equipment serving the whole lifecycle of nuclear power plants, covering plant construction and daily operation & maintenance.

During nuclear power station construction, this series crane undertakes hoisting of core heavy equipment including steam generators and reactor pressure vessels. In daily operational scenarios, it handles reactor pressure vessel top covers, pressing assemblies, fuel baskets and spent fuel storage containers.

1. Hoisting heavy core equipment: steam generators, reactor pressure vessel top covers, spent fuel containers, generator rotors and other large machinery parts.

2. Safe transfer of nuclear assemblies: fresh fuel assemblies, spent fuel assemblies, control rod assemblies and related core components.

3. Routine inspection, overhaul and maintenance of nuclear island and conventional island equipment.

4. Lifting oversized structural components during the civil construction phase of nuclear power plants.

If you have unique special lifting demands for niche industrial scenarios, feel free to reach Weihua for exclusive customized crane solutions.

1. Support full wireless remote control mode to isolate operators from radiation hazardous zones.

2. Adopt single-fault tolerance protection and full multi-redundancy safety architecture to eliminate single-point failure risks.

3. All drive mechanisms are configured with sufficient startup torque to guarantee stable operation under maximum unilateral wheel load bearing conditions.

4. Every structural component undergoes rigorous strength verification calculation, with comprehensive protective measures integrated for the crane main body.

5. Ultra-high positioning precision within ±5 mm for trolleys and hoist beams.

6. Ring rail nuclear cranes are equipped with 3D real-time positioning visualization system to display the hook’s exact spatial coordinates dynamically.

Main Classification of Nuclear Power Cranes

1. Spent fuel container handling crane

2. Conventional island main overhead crane

3. Numerical control & remote intelligent crane

4. Nuclear auxiliary workshop crane

5. Circular ring rail special crane

From functional perspective, nuclear cranes fall into two categories: mechanical component handling cranes and radioactive nuclear material transport cranes.

Weihua Crane delivers fully tailor-made nuclear-grade overhead crane packages exclusively built for nuclear power stations and nuclear engineering construction facilities. Featuring heavy load capacity and micron-level precise manipulation, these custom cranes meet stringent nuclear safety standards for equipment installation, daily overhaul and radioactive core component transportation.

All core technical indicators including lifting tonnage, working span, vertical lifting height and track gauge can be flexibly adjusted to match different nuclear plant layouts and strict nuclear-grade hoisting specifications, supporting high-efficiency, steady and ultra-safe continuous operation under strict nuclear industry quality control environments.
