Performance highlights SHK-D Intrinsically safe cabled load shackle

The SHK-D Series is a high-precision load shackle designed for lifting and weighing in tough industrial environments. Based on the Crosby™ G2150 shackle and available in rated capacities from 1 to 35 tonnes, it offers excellent load accuracy, non-repeatability below 0.1%, and environmental protection to IP67.

Usage conditions

Ideal for rugged field applications, the SHK-D performs reliably from -20°C to +70°C and supports hazardous area operations (ATEX Ex i / Ex d from 3.25 tonnes). The load pin is internally gauged and fully sealed, offering dependable performance in subsea, offshore, and cable tension environments.

Possible applications

  • Under-hook hoist and crane weighing
  • Towing and mooring tension monitoring
  • Cable tensioning systems
  • Safe load monitoring in cranes
  • Offshore lifting operations
  • Subsea tension control

Advantages of choosing this product

With easy installation, certified shackles, and flexible configuration options like signal conditioning, telemetry, and custom electrical connectors, the SHK-D is a versatile choice for demanding load monitoring tasks. Available with optional centralising bobbin to improve accuracy under non-uniform loading.

Other important features

  • 150% proof load and 300% breaking load
  • 10m PUR cabled connection (standard)
  • Optional voltage, current, RS232, or RS485 outputs
  • Subsea variants with underwater mateable connectors
  • Lloyds, ABS, or DNV witness testing available
