June 19，Shandong Special Equipment Inspection and Testing Research Institute designed and developed by Fangyuan GroupPTType test of 6515 flat-head tower crane，The product passed the test successfully.。

Test according to《Type test rules for crane》，YesPTMain structural stress of 6515 tower crane、Inspection and review of safety protection devices and technical design documents。The test results show that，Produced by Fangyuan GroupPTAll performance indexes of 6515 tower crane meet the design requirements.，Comply with relevant standards and type test rules。

PTThe maximum lifting capacity of 6515 tower crane is 10 tons.，Jib length 65 m，Variable arm configuration is more flexible，Be able to adapt betterPCConstruction work。The hoisting mechanism is controlled by closed-loop variable frequency speed regulation.，And that speed regulation range is large，The speed change is smooth、Accurate positioning，With zero servo anti-falling function，To meet the user's more extensive construction needs and flexible construction requirements.。
