Structure characteristics: HydraulicThe speed of bullwheels can be varying stepless in both rotation directions. The pull can be controlled and the volume can be read on the dynamometer. The pull can not be over the max present volume. The speed of reels is corresponding to the bullwheels and automatically controlled to keep the presenting value. Easy operation,safe and reliable,low suits of brake systems fully assure to engage in accident of engine fire out and other suddenness conditions. Automatic overpull protection system Hydraulic oil cooling system Forged bullwheels with wear-proof, heat treated grooves Integral self-loading reel winder with automatic level wind. Standard reel dimensions Hydraulic actuated pulling rope clamp for convenient reel change Hydraulic front jack Mounted on trailer with rigid axle Main components: Engine (CUMMINS in China ) Main hydraulic motor (REXROTH in German) Main hydraulic pump (REXROTH in German) Hydraulic reducer (BONFIGLIOLI in Italy) Hydraulic valve;pipeline system and meter ( made in Italy) Hydraulic puller SpecificationsTypeMax tension (kN)Continuous tension (kn/h)Max speed(km/hBullwheel Nominal Dia(mm)Max rope Dia(mm)Dimensions(mm)Mass(kg)WQT350kn-I3505WQT280kn-II2802505960395400x2350x280012000WQT180kn-II1801505600244550x2200x25005500WQT90kn-IV90805500213600x1950x21503300WQT60kn-IV60505450173280x1750x21003000WQT40kn-IV40355400163200x1700x20002800WQT30kn-IV30255300133200x1600x20001500
