By using this system, the potential energy generated during the lowering of the movable arm device can be controllably converted into hy­ draulic energy to be stored in the energy collector, and the potential energy can also be directly recycled for acting on the movable arm device in balancing mode. The a heat generated by the hydraulic sys­ tem thereby reduced, the is input power of prime motor a is reduced, and the purpose of saving energy achieved. is (57) — f+IfN 6b J Fits J Bum WO 2013/174235 A11 lllll llllllll II llllll III lllll lllll lllll III III III lllll llll llll lllll lllll lllll lllllll llll llll LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW = (84) UP): ARIPO (BW, GM, KE, GH, LR, LS, MW, MZ, NA, RW, SD, SL, SZ, TZ, UG, ZM, ZW), (AM, AZ, BY, KG, KZ, RU, TJ, TM), (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, ML, MR, NE, SN, TD, TG)o - 21 &(3»=
