SHK-B Series bow type cabled load shackle

Robust load shackle designed for reliable weighing and lifting in harsh, offshore or hazardous environments.


Key features

  • Ranges from 1 tonne to 1000 tonne
  • IP67 environmental protection
  • Hazardous Area certification from 3.25t
  • Optional signal amplification and telemetry
  • Centralising load bobbin for increased accuracy
  • Fully certified shackle and load pin

Performance highlights SHK-B Series bow type cabled load shackle

The SHK-B Series is designed to deliver accurate load measurements in extreme environments, including subsea and hazardous areas. With capacities from 1 to 1000 tonnes, each unit is proof loaded to 150% and offers output between 1.8mV and 3.6mV. Non-linearity is typically below ±1%, and non-repeatability under ±0.1%.

Usage conditions

  • Operating temperature: –20 to +70 °C
  • Compensated range: –10 to +50 °C
  • Environmental sealing: IP67
  • ATEX Ex d & Ex i certified from 3.25t onwards
  • Connection: 10 m PUR cable with 4-core screen

Possible applications

  • Under-hook hoist and crane weighing
  • Cable tension monitoring
  • Towing and mooring force measurement
  • Bollard pull testing
  • Offshore and subsea tension control

Advantages of choosing this product

The SHK-B load shackle series is built with premium-grade stainless or carbon steel and uses Crosby or GN Rope shackles for trusted reliability. It’s available with amplified analogue or digital outputs, tailored cable exits, or fully submersible housing for deepwater use. For OEMs or special projects, custom designs up to 2000 tonnes can be delivered with short lead times.

Other important features

  • Optional centralising bobbin to reduce point load errors
  • Wireless telemetry version available (TELSHACK-B)
  • DNV, ABS or Lloyd’s witness testing available
  • 3.2 Material Certification on request
