High-Performance Safety Protection for SANY and ZOOMLION Lifting Machinery

Understanding the ZN101 Series Versatility

The ZN101 Series represents the industry standard for anti-block (Anti-two block) protection in modern hydraulic cranes. Whether you are operating a truck crane, crawler crane, or all-terrain crane, these switches serve as the critical final signal to prevent hook-to-boom collisions.

• ZN101K: The most widely used “standard” model, known for its high-precision internal contacts and durability on SANY STC and ZOOMLION QY series truck cranes.
• ZN101F: Often featuring specialized electrical connectors (such as DT or aviation plugs), designed for specific digital control systems in newer S-series and T-series models.
• ZN101N: A heavy-duty or multi-functional variant frequently found in large-tonnage crawler cranes and specialized tower crane lifting mechanisms.
