Material The steel of crane is from Chinese famous steel companies.2. )Electrical mechanismElements for electrical system are Schneider.3. )Hoist mechanismBrake wheel adopts cast steel materials, surface quenching and external circular, control the beating degree strictly. At the same time, also carrying on balance tests. each hoisting mechanism is carrying on no-load, static load, dynamic load and so on, guarantee the reliability, safety and durableness. 4. )Ranging/Trolley mechanismtrolley mechanism with free maintenance planetary reducer and cone brake motor, is well-knit in structure, stable and powerful in trolley, high endurance and low failure rate. 5. )Slewing mechanismSlewing motor adopts winding motor and hydraulic transmission. 6. )Operation device Cabin with humanized design, is convenient and comfortable, facilitate for safe driving. It creates a good working environment for the operator. 7. )Safety devicesThe crane has a complete set of safety devices: crane high limiter, weight limiter, moment limiter, circumventinglimiter, etc. MECHANISMDescription of QTZ series tower Crane1)QTZ seriestower crane adopts standard section hydraulic lifting and connecting.2)The max. height of crane can reach 180m -200m with wall tie ins.3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting construction, which enables heavy load low speed and light load high speed.The range-change structure drives the trolley cart moving on the horizontal lifting jib, with good positioning performance. Planet gear decelerator is applied in the circumventing structure, togetherwith moment-limiting hydraulic coupler, which can realize high load capacity, steady starting and reliable operation.4) The crane has complete set of safety devices, which can guarantee the safe and high efficient operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..5)The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.FAQQ1: Can provide customized products?A1: Yes. We are hi-tech enterprise affiliated to China Academy of Building Research.
