Giga Jul—Combines the Functions Of a Standard And an Assisted Braking Tuber

Edelrid belay device Giga-Jul NEW
Edelrid belay device Giga-Jul standard and assisted braking tuber

The Giga Jul is particularly light and simultaneously robust and abrasion resistant. This is made possible by a smart hybrid construction of aluminum and steel. The main body of the Giga Jul is made from particularly light aluminum. Parts which are at risk of wear (for example the friction channels) are made from robust stainless steel. Another chapter in our Steel Story.

By moving the green slider, the Giga Jul is instantly transformed from an assisted braking tuber to a standard tuber.

In recent years, the use of assisted braking tubers has dominated sport and alpine climbing. Its advanced safety reserves, which result from its assisted braking when arresting a fall, makes the use of this type of device especially advisable. For this reason the Alpine Associations of Germany, Austria and Switzerland (DAV, ÖAV, SAC) recommend the use of assisted braking tubers.

Nevertheless, there are applications (particularly in alpine climbing) where the use of standard tubers is still advantageous. Especially when secured from a fixed point (belay station), their highly dynamic braking performance may be preferred. Abseiling and belaying the second with a doubled rope is markedly more comfortable with a standard tuber.

WHAT IS ASSISTED BRAKING GUIDE MODE?

Added safety! In principle, a so-called assisted braking tuber works exactly like normal tubular belay devices, even if the shape does not always suggest it.

These devices have a mechanism which, in the event of a fall, creates such strong friction that the rope can no longer run through. Therefore catching a fall is less dependent on the belayer's manual force. Assisted braking tubers offer significantly higher safety reserves than standard tubers. However, it is vital to always follow the manufacturer's instructions regarding the carabiners to be used and the permitted rope diameter. The extremely high braking performance can only be guaranteed if the correct rope diameter is used. The thicker the rope, the greater the friction generated and thus the effective braking of the rope. Nevertheless, the brake-side hand principle must of course also be adhered to when using an assisted braking tuber. It should be noted that due to the enormously high braking performance of the assisted braking tuber on the rope, a dynamic belaying technique should always be utilized. As suggested by the EN 15151-2 standard, our assisted braking tubers are also tested as manual braking devices. However, this is not mandatory and each manufacturer has its own policy on this issue.

 

 

 

ADVANTAGES

of assisted braking guide mode

Very high safety reserves due to higher braking performance

Intuitive to use
Minimal kinks in rope

DISADVANTAGES

of assisted braking guide mode

Dynamic belaying only possible via body dynamics
Handling requires practice

 

 

 

WHAT IS GUIDE MODE?

According to the German Alpine Club (DAV), standard tubers are now by far the most used belay devices. All EDELRID tubular belay devices confrom to the stipulated values in the EN 15151-2 standard. Even today, standard tubers basically correspond to the original Sticht plate. Many climbers still talk about belay plates when using tubular devices. The braking performance works on the double-bend principle. The rope is thus bent twice: once around the carabiner and once downwards on the device. Friction increases the braking performance to the extent that a belayer can manually arrest a fall. However, in a tubular belay device the brake performance increase only works if the brake-side of the rope is held downwards and therefore the second bend is created. A misuse of the device can be extremely dangerous with drastic consequences. If the brake-side of the rope is released or held above or in front of the tuber, the belayer has hardly any chance of holding the rope in the event of a fall and can no longer prevent the lead climber from falling to the ground...
The big advantage of standard tubers is that they are dynamic. This means that a section of the rope is still running through the device until the fall is compeletely arrested. With a little practice, it is therefore possible to belay very dynamically with standard tubers.
This means if the lead climber falls, they will do so more softly. In addition, these devices allow quick paying out and quickly taking up slack.
