Expansion Shell Bolts Type KE-3W and KE3-2K

Expansion shell bolts KE-3W and KE3-2K are designed to be used for roof and ribs support in mine working areas as an independent or secondary bolting support system and also to attach various components of mining equipment.

Expansion shells of ø36 mm are the elements which set the bolt in the hole. The KE-3W shell consists of 3 shells and one expander while the KE3-2K shell consists of 3 shells and 2 expanders.

Simple and easy to install for immediate support to a work area, the expansion shell creates a point to anchor into the hole by turning the bolt. The shell tightens to the rock creating tension at the foot of the borehole, transferring the load from the bolt head and plate to the rock via the shell.
