Fixing Points
This arrangement provides lifting redundancy. One issue that has been observed is that on rare
occasions the shackle attached to the back-up eye does not always rotate smoothly and can cause
an unexpected ‘jump’ on pick up. This is not a cause for concern but can be alleviated in the
following way.
Always ensure the shackle insert (p/n 220-10-03) is always installed correctly onto the shackle pin
installed on the back up (longer leg) of the lifting assembly. This part assembly is shown in Detail D
of drawing 220-3-A in
Appendix B . The shackle pin insert prevents the shackle from assuming a
contorted position which could result in a foreshortening of the beck up leg.
Always ensure the main shackle retaining bracket (p/n 220-10-05-A) is properly installed when
making up the main lift shackle to the lift eye plug. This part assembly is shown in Detail E of
drawing 220-3-A in
Appendix B . The purpose of this retaining bracket is to present the main shackle
in an upward and ‘ready for lift’ orientation. It is possible that this bracket gets distorted in use and
can cause subsequent damage to the sling thimble. It is recommended to also keep a few spare
brackets available for easy replacement as required.
5.5 Use of Tag Lines
Tag lines (Hand Lines) are not supplied with the FROG. However if users wish to use tag lines for
handling the FROG the following should be considered:
Tag lines should be attached to the floor grating and 30 x 30 brace at the edge of the
doorway (see below). Reflex Marine Ltd suggest one or two 3 m lines are practicable for handling
the FROG, however length of line used is at the discretion of the deck crew.
Be aware of specific risks arising from use of tag lines:
i. Deck Crew using Tag lines will be standing closer to frog during landing, which increases the
risk of impact or being caught in between.
ii. Ensure Tag lines are not tied or caught on any adjacent equipment of structures.
iii. Ensure Tag lines are clear of knotting and deck crew have suitable hand and eye protection.
5.6 Seating and Load Distribution
In order to perform loading efficiently and safely, the
following procedures are recommended:
i. Organise passengers into groups of 3 (see note*).
ii. Confirm that passenger and luggage weight
combined does not exceed the SWL of the FROG-
3 unit: 330 kg (or 3 x 110 kg).
iii. Confirm the passenger weight does not exceed
the maximum allowable passenger weight of 270
Kg. (3 * 90 Kg).
iv. Load the Group 1 (1, 2 and 3) into the seats as
shown.
*Note - When the FROG-3 is used for less than 3 passengers, the unit
will remain well balanced.
