Description

Product Overview
Quenching Bridge Crane is a specialized lifting solution designed for metal heat treatment production lines. It is widely used to transfer and immerse high-temperature workpieces, such as shafts, bars, and forgings, into quenching media including water, brine, or oil, ensuring uniform metallurgical properties and improved mechanical performance.
Equipped with a precision positioning system and a heat-resistant C-hook lifting device, the crane enables fast, safe, and accurate handling throughout the quenching process. Workpieces are automatically transferred from the heating furnace to the quenching station and immersed in the quenching medium within 3–5 seconds. Controlled by an advanced PLC system, the crane delivers efficient, reliable, and fully automated operation for modern heat treatment facilities.

Key Advantages
High-Precision Quenching Operation
The synchronized dual-lifting-point system ensures lifting accuracy within 3 mm, maintaining excellent load balance during the quenching process and improving heat treatment consistency.
Rapid Immersion Performance
With a lowering speed of up to 16 m/min, the crane can immerse workpieces into the quenching medium within 3–5 seconds, helping achieve uniform metallurgical properties and reliable product quality.
Outstanding Positioning Accuracy
An advanced positioning system combining absolute encoders and laser correction technology provides repeatable positioning accuracy of ±1 mm for precise workpiece handling.
Enhanced Operational Stability
The integrated anti-sway control system minimizes load movement during lifting and lowering, ensuring safe and accurate placement of high-temperature workpieces.
Flexible Lifting Solutions
Multiple lifting attachments, including C-hooks, electromagnetic lifting magnets, and mechanical clamps, are available to accommodate different workpiece types and production requirements.
Intelligent and Automated Control
The PLC-based control system supports remote, local, and centralized operation modes, enabling efficient and fully automated production line integration.
Comprehensive Safety Protection
Multiple safety features, including dual brakes, overload protection, overspeed protection, emergency release functions, and explosion-proof configurations, ensure safe and reliable operation in demanding environments.

Technical Features
Heavy-Duty Double-Girder Structure
The crane adopts a box-type double-girder, double-rail design fabricated from high-strength Q345B steel, providing excellent rigidity, durability, and load-bearing capacity for heavy-duty quenching applications.
Synchronized Dual-Drum Hoisting Mechanism
A single-drive dual-drum hoisting system with an automatic wire rope leveling device maintains precise synchronization between lifting points, ensuring stable handling of long shafts and large forgings.
Advanced Traveling Mechanism
The traveling system features integrated three-in-one drive units, torsion-resistant wheel assemblies, and horizontal guide wheels for smooth and reliable crane movement.
Modular Spreader System
Interchangeable lifting devices are available, including heat-resistant C-hooks, electromagnetic lifting magnets, and custom mechanical clamps to suit different heat treatment processes.
Intelligent Positioning Technology
Absolute encoders and laser position correction technology enable millimeter-level positioning accuracy and automatic compensation for wire rope deviation.
Three-Dimensional Anti-Sway System
Rigid guide columns, horizontal guide wheels, and variable-frequency anti-sway control work together to limit load swing and improve handling precision.
PLC-Based Electrical Control System
The electrical system integrates an explosion-proof PLC cabinet, temperature sensors, position feedback devices, and industrial communication modules for reliable automated operation.
Multi-Level Control Modes
The crane supports wireless remote control, ground control stations, and centralized supervisory control systems, providing flexible operation for various production environments.

Applications
Widely used in machinery manufacturing, wind energy, aerospace & defense, automotive production, rail transportation, metallurgy, marine engineering, and mold manufacturing for the heat treatment and quenching of shafts, gears, forgings, turbine components, railway parts, marine equipment, and precision molds.
