Construction Tower Crane

complete safety devices,●Max Load: 4t/6t/8t●Jib Lenghth: 50-60m●Rated Lifting Moment: 500KN.m—1250KN.m●Max Lifting Height: 120m/140m/220m●Max Load at Jib End: 1t/1.1t/1.3t/1.6t●Standard: GB/T 5031--2008 Features:Steel Structure Steel is the essential safety guarantee for tower crane. The steel we use for our tower crane is tower crane usage special square steel from Wuhan Iron and Steel Group. Steel material for those essential parts like lifting jib, tower top, frame etc is 16 Manganese Steel. Thus to assure safety, advance and high performance of the crane Main lifting motor:   thermal protection and currency protection. Luffer It applies double-speed or three-speed motors for speed change control according to the jib length, easy running control, low impact force, high operation stability and high efficiency. Safety A.Overload protection: If the material is over the capacity, the crane will give a sharp warning for protection itself. B.Emergency brake: If the operation staff  encounter some emergency situation, we could start the emergency brake system to protection the related treasure.C. Except for using the common security devices, we uniquely equips high definition operation tracking monitor system which can thoroughly supervise the lifting hook, ground and construction building and can assure safety operation when with sightD.Control Method:Room control or remote control to avoid any injure to the operation staff. Operating System Newly spacecraft type cabinet room with air conditioning system, wide eye view, high consideration of operator comfortableness and maximally to low down operation fault rate. ■Technical DataPerformanceQTZ63QTZ63QTZ63QTZ63QTZ80QTZ80QTZ100QTZ125TC5010J-4TC5011-4TC5013-6TC5611-6TC5613-6TC6010-6TC6013-8TC6016-8Rated Hoisting Moment(Kilo-newton/meter)63056063063080080010001250Maximum Loading Capacity(t)44666688Working Range(m）3-502.5-502.5-502.5-562.5-562.5-602.5-602.5-60Lifting height (Fixed/ Attachment)40/12030/14040.5/22040.5/22040.5/22046/22046/22046/220Rated Lifting Capacity at the end of Jib(t)111.31.11.311.31.6Lifting Speed(meter/minute)2 Magnification65.6/32.8/9.280/40/8.580/40/8.8880/40/8.8880/40/8.8880/4080/40100/504 Magnification32.8/16.4/4.640/20/4.240/20/4.4440/20/4.4440/20/4.4440/2040/2050/25Slewing Speed(turn/minute)0-0.620-0.600-0.600-0.650-0.650-0.650-0.80-0.8Luffing Speed(meter/minute)40/2040/2040/2040/2040/2053/27/120-550-55Entire Total Power(kilowait)30.426.13132.834.734.74552MOQ1 setDelivery Time （days）1212121215152020Delivery PortQingdao or Tianjin
