  The main cause of tower crane accidents is congenital deficiency. The production quality of tower cranes directly determines the life of tower cranes. Some enterprises strive to reduce product cost by expanding market share. They do not design according to national standards and design specifications, reduce product performance, and cut corners. Even if we "repair old and waste", today we will learn about their safety knowledge.
  In order to ensure the normal and safe use of the tower crane, the tower crane must have the specified safety devices during installation, mainly including: lifting torque limiter, lifting weight limiter, height limiter, amplitude limiter, and swing limit. hook safety device, reel safety device, wind direction anemometer, wire rope grooving insurance, trolley anti-break rope device, trolley anti-break shaft device and buffer. These safety devices ensure that they are intact and sensitive.
  The tower crane frame adopts no tie rod type,  and the connection design is more simple. This design form greatly facilitates the operation of the air change arm and the arm release. The boom frame is disassembled in the air and the overall lifting is compared with the lifting device. The requirements are greatly reduced, which not only avoids the complexity and high risk of the air removal lever but also saves the disassembly costs. The installation and commissioning of the tower crane tower is low: the tie-barless design of the flat-head tower crane reduces the height of the tower top, and is especially suitable for the cross-joint operation of the tower tower, which greatly improves the working efficiency of the tower crane, and has small unit mass and low installation height. Reduce the height difference between the towers, save space and save costs.
  The flat-head tower crane of the project is easy to install and can be replaced at any time (increasing or decreasing the number of booms within the maximum working range) to meet the requirements of different working conditions, and is more suitable for group tower crossing operations and construction sites. Tower crane disassembly under restricted conditions.
