Greenlee Ton Hydraulic Crimping Tool, 1.4" Opening - HKL1232 23521

Q: What is the Greenlee HKL1232 (23521) used for?
A: It is a 12-ton hydraulic crimping tool designed to crimp copper and aluminum electrical lugs and splices onto cable in industrial and utility applications.

Q: What is the crimping capacity?
A: It delivers 12 tons (24,000 lb) of hydraulic crimping force, allowing reliable compression of heavy-duty connectors.

Q: What cable sizes does it support?
A: It is commonly used for 8 AWG up to 750 kcmil copper and aluminum conductors, depending on the die set used.

Q: What is the jaw opening size?
A: It features a 1.4 inch (32 mm) C-style jaw opening for positioning connectors and dies.

Q: Does it include dies?
A: Typically, the tool uses interchangeable U-style 12-ton dies (KC12 / KA12 / KD12 series), which are usually sold separately depending on the kit.

Q: What materials can it crimp?
A: It is designed for copper and aluminum compression connectors, including color-coded lugs and splices.

Q: Is it manual or powered?
A: It is a manual hydraulic tool using a hand pump mechanism, requiring no electricity.

Q: What makes it suitable for field work?
A: It is portable, self-contained, and rugged, making it ideal for on-site electrical termination work where battery or electric tools may not be available.

Q: What is the main advantage of this tool?
A: It provides high-force, consistent crimps for large conductors, improving connection reliability and reducing failure risk in power systems.

• Inspect dies before use: Check crimping dies for cracks, wear, or deformation to ensure consistent, secure crimps.
• Clean after every job: Remove copper/aluminum residue, grease, and debris from jaw area to prevent binding.
• Lubricate moving joints: Apply light machine oil to pivot points and ram surfaces to maintain smooth operation.
• Check hydraulic system: Inspect hoses, seals, and fittings for leaks or pressure loss before operation.
• Verify full crimp pressure: Ensure tool reaches full pressure cycle for proper UL-rated compression results.
• Inspect quick-coupler connection: Confirm secure attachment between pump and tool to prevent hydraulic leakage.
• Avoid overcapacity use: Do not exceed 12-ton rating or use beyond 1.4" opening limits.
• Keep dies aligned: Ensure die sets are properly seated to prevent uneven or incomplete crimps.
• Protect from corrosion: Store in a dry case, lightly oiled, especially after use in humid or outdoor environments.
• Routine inspection schedule: Perform periodic checks on ram wear, die retention, and hydraulic seals for long-term reliability.
