Individual, centrally powered hydraulic props manufactured by “AZIS” - Mining Service Sp. z o.o. are designed for supporting workings in underground mining plants. They are mainly used in burst-prone and not prone to bursts coal seams to maintain specific dimensions in certain time necessary for operation, where staff, equipment and devices are working.
The prop can also be used in performing other auxiliary work during underground work connected with mining, transport and repair of devices and equipment in a manner compliant with approved workplace instructions.
Depending on the dimensions of the working and seam thickness appropriate prop dimensions are selected.
Types of prop series have the same hydraulic part, the heights are adjusted by mounting extension bushes to the base of the cylinder (mechanical extension).
