Ulven Shackles – Designed for the Logging Industry
At Lifting.com, we offer a wide range of Ulven logging shackles, built for skidding, yarding, cable tensioning, and controlled load release. Below are some of the most popular models and their applications:

#101 Screw Pin Shackle – Fast & Versatile for General Logging Use

• Features a hex-head screw pin, allowing for quick installation and removal.
• Ideal for temporary rigging setups where the connection needs to be changed frequently.
• Available in various sizes to accommodate different loads and line sizes.

#102 Bolt Type Shackle – Secure & Tamper-Resistant

• Includes a bolt, nut, and cotter pin for added security and long-term reliability.
• Prevents accidental loosening, making it ideal for permanent or high-vibration applications.
• Commonly used in logging mainlines, yarding systems, and tower rigging.

#106 Straight Side Bolt Type Shackle – Wider Openings for Load Distribution

• Features a straight-sided design, allowing for wider strap placement or multiple sling connections.
• A bolt-type closure ensures the shackle stays locked under continuous load.
• Used in heavy forestry rigging and load stabilization.

#109 Knock Out Pin Shackle – Designed for Controlled Release Under Load

• Knock-out pin design allows loggers to release the pin while the shackle is under load, ensuring safe disconnection in high-tension situations.
• Used by professional loggers and yarding crews where loads must be released without unhooking manually.
• Requires a sledgehammer or similar tool to knock out the pin, making it a safer alternative to standard release mechanisms in high-load scenarios.

#110 Flush Pin Shackle – Streamlined for Running Through Blocks

• Designed with a flush pin to prevent snagging, making it ideal for running through sheaves and blocks without hanging up.
• Used in logging rigging setups where smooth operation through pulleys is required.
• Provides low-profile, high-strength performance for efficient and consistent movement in cable-based logging systems.

#126 Guyline Sleeve Shackle – Built for Tower and Highline Stability

• Specifically designed for guyline applications, providing a secure and reinforced connection for stabilizing logging towers and yarders.
• Reinforced with a sleeve design for superior durability and tension control.
• Used in high-lead logging and tower stabilization operations.
