HIGH PRESSURE MULTI-PILOT HOSE ASSEMBIES


High pressure multi-pilot hose assemblies are designed for connection of two hydraulic distributors: main and
control that are used for control neighboring shields in the longwall system. The high pressure multi-pilot hose assembly is a system of parallel high pressure pilot-lines fitted together in one unit.

The unit consist of protective one-wire braided rubber hose crimped at its ends in connecting terminals with
ferrules, while inside there is a set of parallel thermoplastic hoses of 3mm or4mm fitted into the connecting
terminal with plug-in (male) type fitting.

Amount of 3 or 4mm hoses in multi-pilot hose can differ from 8 to 24 pieces. It depends on number of
functions in main and control block distributor and number of functions necessary to control the shields.

All our high pressure multi-pilot hoses have proper certifications and approvals which allow install those
hoses in underground mining in different hazardous areas and applications.
