Hydraulically coupling hose reel

 

The hydraulic coupling type hose reel is a hose winding device that uses the liquid viscous transmission technology as the working mechanism of the reel slip, and its core technology lies in its liquid viscous slip working unit. Motor-driven hydroviscous coupling hose reels are generally used in three-wall rock drilling rigs, and are installed in pairs with split hydraulic motor coupling cable reels.
