Single Cam Earth Wire Gripper Mechanical Clamping Tool For Ground Wires

Core Mechanical Features​​

• ​​Single cam locking mechanism​​ with hardened steel pivot pin (SAE 4140)
• ​​Hot-dip galvanized carbon steel​​ body (150μm coating per ISO 1461)
• ​​Fixed jaw size​​ for 10-16mm diameter ground wires (including standard OPGW)
• ​​Manual load limiter​​ via shear pin design (shears at 120% WLL)
• ​​Serrated grip surface​​ with replaceable teeth plates
• ​​Rotating base​​ with bronze bushings for smooth operation

​​Operational Mechanics​​
✔ ​​Hand-powered operation​​ - no hydraulic/pneumatic input required
✔ ​​Progressive grip enhancement​​ through cam action
✔ ​​Visual load indicator​​ - color marks show safe tension range
✔ ​​All-mechanical overload protection​​ - shear pin fails at 12kN
✔ ​​Standard wrench points​​ - compatible with 19mm/24mm tools

​​Durability Specifications​​
• ​​2000-hour salt spray tested​​ (ASTM B117)
• ​​Grease lubrication ports​​ at all moving joints
• ​​Field-replaceable wear parts​​ using basic hand tools
• ​​Drop-forged steel components​​ (minimum tensile strength 500MPa)

​​Mechanical Safety Systems​​
✓ ​​Positive locking lever​​ with secondary safety latch
✓ ​​Rust-proof stainless steel fasteners​​ (AISI 304)
✓ ​​Manual reset required​​ after overload release
✓ ​​Non-conductive fiberglass handles​

​

​​Basic Maintenance Requirements​​

• ​​Monthly grease application​​ (NLGI #2 lithium-based)
• ​​Annual pivot pin inspection​​ for deformation
• ​​Jaw tooth replacement​​ every 5,000 cycles
• ​​Shear pin inventory​​ (2 spare pins included)

​​Fundamental Applications​​
