Quick release towing hooks - type GSH

Our quick release towing hook type GSH (also known as disc hook) is especially designed to guarantee safe operation on work boats, supply vessels, harbour, coastal, fire fighting and tugboats.

The GSH towing hook can be operated manually by means of a lever or a rope with a maximum effort of 15 kg at full load. A two-step release mechanism prevents accidental opening. It can be reset manually very easily, as the disc is counterbalanced. During the release, the rotation reduces the energy impact to a minimum.

The Straatman quick release towing hook type GSH (disc type) is available in a range of SWL 15-100 Tonnes.

Quick release towing hook for work- and tug boats

Besides our well known quick release towing hook type GSH, we have developed a small and light towing hook type BG-7, especially designed for small tug boats and work boats. The smart design has led to a light and low cost towing hook.

The BG-7 can be operated manually by means of a lever or a rope with a little effort of maximum 15 kgf at full load. A two-step release mechanism prevents accidental opening. It can be reset manually very easily, as the disc is counterbalanced. During release, the rotation of the disc reduces the energy impact to a minimum.

The Straatman quick release towing hook type BG-7 has a SWL of 7 Tonnes and is load tested at 2x SWL.

Testing of quick release towing hooks

All our quick release towing hooks are tested on our calibrated 3.500 KN hydraulic testing machine.

Each disc type towing hook (GSH and BG-7) will be tested at 200% of the safe working load, with the exception of the GSH-100. This hook is tested at 150% of the SWL. All hooks undergo a release performance test at the safe working load.

If so desired, the test can be witnessed by any classification authority of your choice.

All factory and witness test certificates will be provided as a part of the user manual and construction file.
