General purpose overhead crane
Electric Single Beam Crane for Pickling
Product Overview
The Electric Single Beam Crane for Pickling, developed by Weiyuan, is a specialized lifting solution designed to meet the demands of the pickling and galvanizing industries. Engineered to operate in harsh, corrosive environments, this crane features a lightweight, modular, and parametric design for maximum efficiency and reliability. The system utilizes a special-purpose electric hoist for pickling, driven by a three-in-one device and controlled by an advanced variable frequency speed regulation system. With a unique dual-hoist lifting mechanism for exceptional stability, this crane provides a safe, intelligent, and high-performance solution for all material handling needs in surface treatment processes.
Product Advantages
Synchronized Dual-Hoist Stability
The lifting mechanism features two independent electric hoists that can be operated simultaneously or individually. This synchronous operation ensures that long or awkward materials are transported smoothly and kept level, which is critical for dipping operations in pickling and galvanizing.
High-Efficiency Operation
Centered on the hot plating and pickling process, the crane is designed with fast lifting and running speeds. The entire machine can achieve a working level of up to A6, making it suitable for frequent and demanding use in high-throughput facilities.
Designed for Corrosive Environments
Every component, from the specialized pickling hoist to the control systems, is selected and protected to withstand the harsh, acidic environment of a pickling line, ensuring long-term durability and operational safety.
Advanced VFD Control
Equipped with an advanced variable frequency and speed regulation control system, the crane delivers smooth acceleration and deceleration. This reduces load swing, allows for precise positioning over tanks, and enhances overall operational safety.
Lightweight and Modular Design
The crane’s modern, lightweight, and modular structure reduces the load on the factory building, simplifies installation and maintenance, and provides an energy-saving and environmentally protective solution.
Intelligent Safety Features
Incorporates a full suite of intelligent functions, including electric anti-sway, inching movement for precise approaches, zero-speed hover to prevent hook slippage, and regional load limits to create safe, restricted zones.
Application Scenarios
Steel Pickling Lines
The primary application is for transporting steel coils, bars, or fabricated parts through the series of acid tanks required for surface cleaning and preparation before further processing like galvanizing or coating.
Galvanizing and Plating Facilities
Ideal for the pre-treatment stages of galvanizing or electroplating, where materials must be carefully and stably dipped into various chemical baths with precision.
Chemical Treatment Plants
Suitable for any industrial process that involves immersing materials in corrosive chemical tanks, where stability, reliability, and resistance to corrosion are paramount.
Metal Surface Treatment Centers
An excellent solution for any facility focused on surface treatment, where the dual-hoist system provides the stability needed to handle diverse product shapes and sizes safely.

FAQ
Q: What is the main advantage of the dual-hoist system?
A: The dual-hoist system allows two independent hoists to lift a single long object in perfect synchronization. This keeps the load level and stable, which is crucial for safely and evenly immersing materials into pickling or galvanizing tanks without tilting or splashing.
Q: Can the two hoists be operated separately?
A: Yes. The system is flexible, allowing for the simultaneous lifting and lowering of both hoists in sync, or the operation of a single hoist independently for smaller loads, adding to the crane’s versatility.
Q: Is this crane suitable for environments other than pickling?
A: While designed for pickling, its corrosion resistance and stable dual-hoist lifting make it an excellent choice for any application involving chemical dipping, electroplating, anodizing, or handling materials in similarly harsh, corrosive environments.
Q: How does the crane achieve stable and smooth running?
A: Stability is achieved through a combination of the dual-hoist mechanism, electric anti-sway technology, and the advanced variable frequency drive (VFD) control system, which ensures smooth starts and stops to minimize load swing.
Q: Can the crane’s operation be automated?
A: Yes. With its advanced control system and the option for a wireless expansion module, the crane can be integrated into a larger automated factory system, receiving commands for precise, repeatable movements along the production line.
