Block Sleeve Extraction/Fitting Kit

Several mines in the UK have experienced difficulty in changing press fit sleeves especially when the sleeve has broken at the neck.
Minnovation were approached by UK Coal to develop a hydraulic activated extraction system that not only extracted worn sleeves but also headless sleeves.
The equipment illustrated below has been successfully used by UK Coal at both Kellingley & Daw Mill Mines for the use on Joy J35 & Kennametal K35 Blocks in situ underground.
On the left below is the arrangement for the Kennametal K35 system and on the right for the Joy J35 system.
