Short Answer: The 10-Ton Tri-Con Swivel is used during pullback to allow the product to rotate independently of the drill string.
Correct use: This swivel is installed between the housing and the product being pulled to prevent torsional load from transferring into the product. The Tri-Con connection allows compatibility with Tri-Con connection tooling eliminaing the need for an extra adapter.
Technical details: The swivel is rated for up to 10 tons of pullback when used within a matched Tri-Con system.
Incorrect use includes: Using the swivel outside of pullback operations or exceeding its load rating. Incorrect use can introduce greater risk of product damage or connection failure.
Short Answer: Yes, Tri-Con coiled pins should be installed through the lead pin hole from the 3 o'clock to 9 o'clock position.
Correct use: Locate the lead pin hole just forward of the lid opening, running from the 3 o'clock to 9 o'clock position. Align the coiled pin with this hole and tap it in using a hammer.
Technical details: Installing the pin in the lead pin hole allows it to be driven out more easily during tool changes because of their position in relation to the limitations of the pit size. This reduces the service time or potential pin damage when punching them out.
Short Answer: The 10-Ton Tri-Con Swivel is compatible with 2-7/8" (-77) Tri-Con tooling.
Correct use: This swivel should only be used with other Tri-Con tools and adapters that share the same 77-series connection size and load class. All components in the string must be matched to maintain proper fit and strength.
Technical details: The 2-7/8" Tri-Con connection (-77) corresponds to a size and is designed for higher pullback loads. Mixing Tri-Con sizes or load classes can compromise the connection.
Incorrect use includes: Connecting the swivel to 76-series (2-1/8") Tri-Con tooling or non-Tri-Con systems. Incorrect use can introduce greater risk of connection failure or load mismatch or introduce safety risks.
Short Answer: Replace as soon as you see any signs of wear or mushrooming. This can be as frequent as each shot, depending on jobsite conditions. Consult the user manual.
Correct use: Before and after each bore, inspect the coiled pins, and mating components for wear or deformation. Keep all contact surfaces clean, apply light grease where applicable, and replace pins that show wear to maintain smooth rotation and fast tool changes
Technical details: Coiled pins are designed to protect the Tri-Con connection by absorbing wear during operation. They are purposefully a wear-item to protect the integrity of the Tri-Con Connection.
Incorrect use includes: Reusing damaged or worn pins or allowing debris to build up in the connection. Incorrect use can introduce greater risk of poor fit, difficult tool changes, or reduced connection performance.
Short Answer: Eye swivels and duct pullers serve different purposes during pullback and are not interchangeable.
Correct use: An eye swivel is used when pulling product that already has an external pulling eye or adapter and needs to rotate independently of the drill string. A duct puller is used when the product must be gripped internally, such as conduit or duct without an external pulling attachment.
Technical details: Eye swivels manage rotation and help prevent product twist, while duct pullers create an internal mechanical grip inside the product itself. The correct choice depends on whether the product has an external pull point or requires internal engagement.
Incorrect use includes: Using an eye swivel when no external pull point exists or attempting to pull duct without proper internal grip. Incorrect use can introduce greater risk of slippage, product damage, or installation failure.
