Overview
The MK1401 is a shear-pin load cell that measures force through the pivot pin itself, directly replacing the original pin with no redesign of the structure. It gives stable, dependable output with a high safe-overload factor and simple installation, which suits lifting equipment where the pin must carry the load and report it.
Key Features
- Replaces the existing load pin directly
- High safe-overload factor
- Stable, reliable output for safety monitoring
- Simple installation
- High accuracy (0.05; 0.1; 0.2; 0.3%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
Applications
Load-limiting safety devices on construction hoists, tower cranes, port machinery, overhead travelling cranes and lifts.
