Varaiable Speed Allowable Hoist Drive with Inverter Driven Motor

      -We are a leading gear motor manufacturerZhejiang Donghai Reducer is a leading manufacturer of gear motor and gearbox.Since 1991, we have specialized in manufacturing a wide range of gear motor and gear box including:  helical gear motorhelical bevel gear motorparallel shaft helical gear motorhelical worm gear motorhoist driveheavy-duty helical gearboxheavy-duty helical bevel gearboxgear motor for car parking systemsprial bevel gearbox  Product DescriptionProduct DescriptionEuropean type low-noise hoist drive is used in the fully intelligent control operation crane system.The hoist drive is composed of strengthened aluminum alloy housing,motor, intergrated thermal protection and brake.The housing of reducer is made of low-pressure cast reinforced aluminum alloy to ensure that the aluminum strength is not deformed and its weight is light. The spline output shaft (European standard) and hard tooth helical gear are made of high-quality 20CrMnTi gear steel. The carburizing treatment ensures the gears' hard teeth surface strength.Then  gears are made by CNC precision grinding to ensure the technical requirements of gear hardness and accuracy. The fully enclosed combination hoist drive has a mechanical transmission efficiency up to 98% and a running noise less than 60 dB (A), suitable for outdoor working condition.The low-noise housing of motor is heat-drawn aluminum alloy, withnheat dissipation and sound-absorbing system. European type  rotor skew-slot stator is precisely wound with copper wire, and is deeply dipped in paint. Insulation class F and H, protection class IP55, working system S1 operation, suitable for outdoor working environment +80 ºC to -25 ºC, not suitable for direct corrosive objects. Frequency conversion could reach to 110Hz, start frequency 1Hz.  Detailed PhotosProduct ShowProduct ParametersProduct SpecificationLifting CapacityLifting SpeedDrum DiameterMotor PowerProtection ClassFrequencyUp to 3.2 ton(dual speed)0.66/4.0;0.8/5.0;1.0/6.3;1.3/8.0m/min at reeving 4/1140mm0.37/2.5;0.45/3.2;0.6/4.0 Kw(12/2 Poles)IP5550HZUp to 6.8 ton(dual speed)0.66/4.0;0.8/5.0;1.0/6.3;1.3/8.0m/min at reeving 4/1170mm0.8/4.9;1.0/6.1;1.3/7.7;1.6/9.8 Kw(12/2 Poles)IP5550HZUp to 12.5 ton(dual speed)0.66/4.0;0.8/5.0;1.0/6.3;1.3/8.0m/min at reeving 4/1266mm1.2/7.6;1.5/9.5;2.0/12.5 Kw(12/2 Poles)IP5550HZUp to 20 ton(dual speed)0.66/4.0;0.8/5.0;1.0/6.3;1.3/8.0m/min at reeving 4/1295mm2.0/12.5;2.6/16.0 Kw(12/2 Poles)IP5550HZUp to 25 ton(dual speed)0.53/3.4;0.65/4.23;0.83/5.35;1.03/6.7m/min at reeving 4/1325mm2.0/12.5;2.6/16.0 Kw(12/2 Poles)IP5550HZUp to 40 ton(dual speed)0.6/2.6;0.8/3.3;1.0/4.2m/min at reeving 4/1405mm5/20 Kw(8/2 Poles)IP5550HZ            Lifting CapacityLifting SpeedDrum DiameterMotor PowerProtection ClassFrequencyUp to 3.2 ton(dual speed)1.2/4.8;1.6/6.0;1.92/7.6;2.4/9.6m/min at reeving 4/1140mm0.72/3.0;0.96/3.6;1.2/4.8 Kw(12/2 Poles)IP5560HZUp to 6.8 ton(dual speed)1.2/4.8;1.5/6.0;1.9/7.6;2.4/9.6m/min at reeving 4/1170mm1.4/5.9;1.8/7.3;2.3/9.1;2.9/11.5 Kw(12/2 Poles)IP5560HZUp to 12.5 ton(dual speed)1.2/4.8;1.5/6.0;1.9/7.6;2.4/9.6m/min at reeving 4/1266mm2.3/9.1;2.9/11.5;3.7/15.0 Kw(12/2 Poles)IP5560HZUp to 20 ton(dual speed)1.2/4.8;1.5/6.0;1.9/7.6;2.4/9.6m/min at reeving 4/1295mm3.7/15;4.8/19.2 Kw(12/2 Poles)IP5560HZUp to 25 ton(dual speed)1.02/4.1;1.3/5.1;1.6/6.4;2.0/8.1m/min at reeving 4/1325mm4/15;4.8/19.2 Kw(12/2 Poles)IP5560HZUp to 40 ton(dual speed)0.8/3.2;1.0/4.0;1.3/5.1m/min at reeving 4/1405mm6/24.2 Kw(8/2 Poles)IP5560HZCompany ProfileZhejiang Donghai Reducer Co., LTD is professionally manufacturing gear motor and gear box, with more than 20+years  experience,And an industrial and trading company have been set up in Shanghai, known as "Shanghai Teguosi Transmission Equipment Co., Ltd", and shorten as " DHC•TGS", mainly researching and developing high-quality transmission equipment, providing complete sets of equipment for the global intelligent industry in accordance with European standards, National standards and Enterprise standards. Our products had been Certified by CE,CCC,CQC,XT. As a leading brand of domestic transmission equipment, it is also a National High-tech Enterprise, a director of the China Heavy Machinery Industry Association, and a Parking Equipment Working Committee and a Bridge Crane Professional Committee. Your reliable supplier ,we assure you the utmost reliability and security for both product and services.  Our AdvantagesOur Advantages: Your professional supplier with 20+years experienceWidely  Used In  Different Industries (Application)PackagePlastic bag + wooden carton FAQFAQ1.Q:What kinds of gearbox can you produce for us?A:Main products of our company:  E, D, T, and P series helical gear motor andhoist   driveheavy-duty helical gearboxheavy-duty helical bevel gearboxgear motor for car parking systemsprial bevel gearbox  more  than one hundred models and thousands of specifications2.Q: How long is your delivery time?A:Generally it is 5-10 days if the parts are i
