• Customized winch photos (CWG-30265)：

Application Background:

The client requires high-frequency vertical lifting operations in construction site and factory environments. Due to the double-line reeving configuration, higher requirements are placed on load balance, stability, and safety. Particularly under a 20-meter lifting height, minimizing load swing and wire rope twisting is critical.

Customer Challenges:

Key technical challenges include：

• Load balance control in double-line operation to prevent uneven force distribution and structural stress concentration
• Wire rope rotation issues causing unstable lifting
• Safety risks associated with high lifting height (20 m)
• Electrical safety concerns in construction site environments

Safety Design Highlights :

• Equipped with an upper limit switch to prevent over-winding
• Low-voltage (24V) control system to reduce electrical risks
• Adoption of non-rotating wire rope for stable lifting performance
• Designed to meet durability and safety requirements for construction and factory environments

Project Results :

Completed within 4 weeks, successfully achieving：

• Stable double-line lifting operation
• Significant reduction in load swing and rotation
• Improved material handling efficiency
• Enhanced operational safety
