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 seagoing tugs.

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.

All hooks are tested on our calibrated 3,500 kN hydraulic testing machine. They undergo a load test of 2x SWL and the release test is done at SWL. All test certificates will be issued as a part of the construction file. If so desired, the test can be witnessed by a classification authority of your choice. Moreover our clients are very welcome to join and witness the tests as well.

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

Applications:

  • Tug boats
  • Work boats
  • Multi purpose supply vessels

Options:

  • Spring loaded shock absorber
  • Customized designs
  • Local hydraulic or pneumatic release
  • Remote controlled release
  • Load monitoring system

QUICK RELEASE TOWING HOOKS – type BG-7

 

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 tugs 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.

Applications:
Small tug and work boats
Small multi purpose supply vessels
