DC Drive Drawworks nan Forage Kapasite Chaj segondè
BEARINGS tout adopte roulo yo ak arbr yo te fè nan asye alyaj prim.
Kondwi chenn ki gen gwo presizyon ak gwo fòs yo fòse grese.
Fren prensipal la adopte fren disk idwolik, ak disk fren an se dlo oswa lè refwadi.
Fren oksilyè a adopte fren elektwomayetik eddy aktyèl (dlo oswa lè refwadi) oswa fren pneumatik pouse disk.
