Description
5′ Epiroc Hydrabolt (Aquabolt) with plate.
Part number 9899810004
The Hydrabolt is a hydraulically expanded rock bolt with superior bond strength
for tensile loading applications. The hollow, tubular Hydrabolt is injected with high
pressure water upon installation and then expands to adapt to the shape of a predrilled
support hole. The Hydrabolt incorporates a check valve to prevent the fluid
from being released once the inflating nozzle is removed. This system provides a
better bond as the inflated tube adapts to the shape, size and irregularities of the
hole and distributes the clamping force evenly throughout the length of the hole.
As the installed Hydrabolt is sealed, the internal corrosion is self-inhibiting.
Hydrabolts are fitted with an integral load indicator that confirms it has been
correctly installed by popping forward once the Hydrabolt has been adequately
pressurized; secondly the color of the load indicator identifies which length of
Hydrabolt has been installed.
