5. Lifting gear safety
There are a large number of lines, blocks,
winches, haulers etc used on fishing boats. All of these take a substantial
load at some time during fishing operations.
It is important that these are used safely
and kept well maintained so they don’t become hazardous.
General
Lifting
- Regularly examine all gear. Your Safe
Ship Management (SSM) system may cover main items but there are often
other smaller items not covered.
- Use certified gear only.
- Get into the habit of checking gear
before you use it.
- Keep blocks and swivels etc well greased
and maintained.
- Remember a load on a crane or davit affects
stability. The vessel will heel when a crane is used.
- Even when the load itself is low the
force is actually acting at the point from where the wire is suspended
(normally through a block) on the boom so the load’s effect on the vessel
will be greater than you may think.
- If along side ensure your fore and aft
lines are tight while “breast” lines should have some slack in them.
- Use competent, trained and experienced
crane or winch drivers.
- Always attach load control lines and
guys.
- Don’t leave loads suspended.
- Make sure you know the Safe Working Load
of the equipment you are using. Remember the SWL is that of the “weakest”
component of the lifting system!
- Make sure all people are wearing safety
hats!
Winch
Safety
- Keep these systems well maintained and
get into the habit of checking the controls before you put a load on the
winch.
- Make sure the handlers know the position
of emergency stops.
- Pass only 3 turns around a surge drum.
- Keep your hands well clear of drum. Pay
about a metre from the drum.
- Riding turns.
- If anything obstructs your view of the
load – stop the movement.
- Always leave a minimum of two turns on
the drum.
- Avoid using a bar to guide wire onto
drum where possible. If necessary make sure there is a second person
operating the winch controls.
Line
handling
- Check lines regularly for broken strands
or fraying.
- Twist open stands to check for internal
wear.
- Avoid kinks.
- Try not to bend wire through a sharp
angle.
- Reverse ends of wire where possible to
avoid uneven wear.
- Listen to sounds from wire under tension
during normal working so you will recognise unfamiliar sounds that may
warn of a potential failure.
- Don’t overload lines and avoid putting a
sudden (shock) load on.
- Rollers and sheaves of blocks should be
free to rotate. Keep them greased and their bearings or bushes in good
shape.
- Avoid using synthetic lines on surge
drums.
