4.Dahan tower crane is the enterprise which to start with commenced to use the robot welding lines. At existing, we have a fully automated robot welding creation line for mast sections fabrication made up by a lot more than a hundred welding robots. The production line is composed with automatic substance planning, welding and maching. All principal parts of Dahan tower crane use robotic welding, with the most ept carbon dioxide blended with argon gasoline shielded welding, it has deep depth of fusion, large high quality of welding and secure overall performance.


five. All parts and components of EPT tower crane use high quality makes. Electrical gear with Schneider converter, aviation plug, stainless metal distribution box and 3 linkage console has features of minimal failure price and straightforward installation.
Hoisting system is provided by major manufacturer Jiangte Motor or HangZhou Shengjian, all with motor oil, free of charge servicing, higher dependability and reduced maintenance rate.

six. Interest to element top quality.  High-power bolt adopt shipborne scale DACROMET technology. It can maintain not rusted for 10 years .Swiss screw-thread bolts of preload market 30 per cent than conventional bolts. Weight limiter uses the stress ring framework and solid aluminum shell utilized Hoisting, derric ept restricting stopper to prolong provider existence.



seven.Massive constructions as mast segment, turn capable, prime kit and hoisting jib adopt innovative gear as NC equipment instrument, drilling machine, milling machine processing following welding. That efficiently assures products assembly accuracy, reducing the failure rate and bettering the security.


eight.12 computerized spraying assembly line, the entire machine adopt impeller blasting to make sure the cleanliness of steel area and remove the inside pressure creating in welding approach, boost the toughness and metal surface hardness, improve portray adhesion.

System, the small car, fence and other small items adopt very hot dip galvanized after acid phosphate treatment method, rust resistance stronger.


9.Hoisting, derric ept and slewing mechanism, with total security this kind of as torque, excess weight restrict. The steel wire rope broken rope unit. Range of the vehicle style against loss and broken shaft, this kind of as tilting system. The electrical adopts overload protection, the layout of PLC self-diagnosis technique, it is practical to servicing.



ten.Dahan three creation bases is ZheJiang , ZheJiang , ZheJiang .  EPT tower crane are exported to much more than 50 nations around the world and locations. We have a lot more than 1000 sets right after-income services network. We carried out the earliest stagnation level services mode in this tower crane ept that guarantee the high quality of services and performance. Otherwise, better to remove customer’s concerns.
