Safety test of SpiderJack 3 produced in 2016

12th April 2017

If the bonding of the grub screw to the thumb brake ofSpiderJack 3 is defective, this can obstruct the movement of the friction clutch or the device body. In the worst case scenario, the device no longer grips the rope safely. After I had been informed that the clamping action was affected in this manner on a SpiderJack 3 with serial number: 25.16…, it is possible that more devices are affected. In the past, the bonding of the grub screw to the brake bearing has been safe and reliable in tests.

To discover whether there are more insufficiently bonded grub screws on SpiderJack 3, every user must check thesetwo screws (Abb. 1).

Therefore, every user of a SpiderJack 3, serial number: 25.16… is asked to carry out this check without delay based on the following instructions (Abb. 2).
Spiderjack 3 warning 2

For the test, please use the thinner hex driver (2.5 mm) that is supplied with SpiderJack 3. It is important that the hex driver is held on the short side, as shown (Abb. 2). If the user cannot turn the two grub screws with the method shown using normal force (1 to 1.5 Nm), everything is OK and the SpiderJack 3 is safe. It does not matter which direction the screw is turned. However, if one or both of the two grub screws can be turned, the SpiderJack 3 must not be used until the problem has been resolved. If the grub screws are not tight,contact us without delay. Naturally, we will send you a free repair kit with instructions immediately.

Owners of SpiderJack 3, serial numbers: 25.17… with thenew grub screw (Abb. 3) do not have to carry out this safety test. The new grub screws with head are also mechanically fixed in place and proper bonding of every single screw is checked twice.
