Visually inspect in situ for any signs of wear, cracks, deformation or other damage
2.
Main Lift-Eye Plug M16 Bolts
(Critical Part)
Visually inspect the two M16 lifting eye bolts, nuts, split pins and tamper proof seals that connect the main lift-eye
plug to the central column for wear or damage.
3.
M48 Keel Boss and M10 Cross Bolt (or roll pin on older models)
(Critical Part)
At the bottom end of central column, visually inspect the M48 keel boss nut and ensure that the M10 cross bolt
(keel plate nut roll pin on older models) is secure c/w split pin & tamperproof seal. Check the presence of anti-
rotation fittings and that all bolts are secure. Do not go underneath an active lift.
4.
Lifting Sling Set
(Critical Part)
The lifting sling set (including attachments) must be visually examined by a Competent Person.
Note: High visibility cover must be completely removed to allow inspection of steel wire rope components. Replace
the sling set according to the usage of the FROG (see Table 3 in
). This may be as frequently as every 3
months. Irrespective of apparent condition the lifting sling set should be replaced at least every 12 months.
Note serial number and test
date stamp (specify decision to
retain or replace).
5.
Sling Anti-Fouling -
Check the lifting assembly anti-fouling bracket and shackle spacer (or the anti-fouling tie wraps
if an earlier model) are in good condition (
). Replace as necessary.
6.
Backup-Eye -
Visually inspect for any wear or damage and check that the split pin and tamper proof seal are intact.
7.
Main Seat Spring Check
The Frog-3 Spring can be susceptible to yield over time. The Frog-3 spring is deemed fit for purpose until it yields
beyond 5% in length. This can be verified by measuring the free length of the spring or measuring the deflection of
the seat base in-situ. The following checks are recommended to identify whether the spring is fit for purpose:
1. In-situ check
The Frog-3 Sliding Sleeve Cross Bolt Runner should rest against the slotted Sliding Sleeve,
with a pre-compression force of approximately 60kg. If a space exists between the slot edge
and the Cross Bolt Runner greater then 13mm, the Spring should be replaced.
2. Free Length check
Free Length of a new Frog-3 Spring is 825mm (+/-16mm). If the Free Length is less than
785mm the Spring should be replaced.
