ISC Wales has released a User Inspection Notice for the ISC RP074 Zippey Trolley and ISC RP205 / RP 209 Pip-pin Rope Grab. ISC requests that all owners of the above listed items perform a visual inspection as outlined below.
ISC RP074 Zippey
There has been a report of the scroll pin working loose over time. This has, currently, only been reported at a single site. Following an investigation into the customer-raised issue, it was discovered there is a possibility that a number of devices may be affected.
The scroll pin is a secondary pin that holds the axle on which the opening latch of the gate hinges. The pin is not structural. If the pin is able to [loosen], and the axle falls out, the gate-opening latch will detach from the gate, removing the second-action locking mechanism.
To visually inspect the trolley, check the position of the scroll pin. If the scroll pin has migrated beyond flush with the gate side, then a repair is required. If the scroll pin is a least 1 mm below the surface of the gate, it is correctly located.
To repair the scroll pin, using a 3 mm parallel punch, a hammer, and Loctite superglue adhesive, gently tap the scroll pin into the hole as far as it can go–it should be at least 1 mm into the hole. Apply a drop of Loctite superglue adhesive to retain the pin. Check the function of the opening latch.
If the scroll pin cannot be repaired, the unit must be returned to ISC.

ISC RP205 / RP209 Pip-pin Rope Grab
There has been a report of the ball bearings falling out of the Pip-pin Rope Grab over time. This has, currently, only been reported at a single site. Following an investigation into the customer-raised issue, it was discovered that there is a possibility that a number of devices may be affected.
The ball bearings act as a locking mechanism for the axle, and if they are not in place, the axle could be or become loose. For this reason, if the ball bearings are not present the device should not be used.
To visually inspect the unit, check that the ball bearings are present. If they are not, the unit must be returned to ISC for immediate replacement. If the ball bearings are present, operators are asked to perform an additional inspection of the unit.
To perform the additional inspection, check for evidence of peening around the ball bearing. While depressing the pip-pin button, “tap” the axle on a hard surface. If the ball bearing remains in place, the rope grab is determined safe for further use. If there is no evidence of peening and/or the ball bearings do not remain in place, the device should be removed from service and returned to ISC for replacement.
