12-ton Construction Crane

The 7020 tower crane can be regarded as a "hexagonal warrior". Its lifting mechanism adopts full variable frequency speed control technology, with the maximum lifting speed reaching 100m/min, significantly enhancing the lifting efficiency; at the same time, it has millimeter-level micro-speed control, perfectly meeting the strict requirements of prefabricated buildings for precise positioning of components. In addition, its multi-stage response closed-loop rotation smooth control technology effectively suppresses the arm rotation jitter, making the operation more stable and efficient

This tower crane widely adopts high-strength cold-formed steel and modular design, with a structural component generalization rate of up to 88%. The new and old standard sections are highly interchangeable, greatly reducing the maintenance and allocation costs of the enterprise. The rich arm length combinations and strong versatility of the counterweight make it possible to flexibly adjust according to project requirements, achieving "one machine for multiple uses".

The 7020 tower crane, with its large coverage radius and strong lifting capacity, is widely applicable to various complex and large-scale construction scenarios. In the construction of super high-rise buildings, large commercial complexes, large stadiums and exhibition centers, it can easily complete the hoisting of large roof steel structures and curtain wall components. In the construction of prefabricated buildings and cross-river bridges, its precise micro-motion performance and strong load-bearing capacity provide reliable guarantees for the connection of prefabricated components. Moreover, in urban renewal projects with limited sites or requiring multi-machine collaborative operations, the 7020 tower crane can achieve efficient and safe group tower operations through BIM technology for detailed site modeling and collision prevention planning.

In terms of hardware and intrinsic safety design, the entire machine adopts a hierarchical structural safety design and overload reinforcement test technology to ensure that the structural forces are reasonable and the safety margin is sufficient. The equipment is equipped with a TSM safety monitoring system, achieving dual protection for both mechanical and electronic systems, truly making "safety visible". The opening state of the lifting brake, the wear condition of the brake pads, and the overheating state of the motor can all be identified and alarmed in real time; the electrical safety device has a tamper-proof function, and once it is removed or fails, an alarm will be triggered immediately. In addition, the equipment is equipped with a fault self-diagnosis system, which can immediately feed back the core fault information to the mobile phone, helping maintenance personnel quickly locate and solve problems.
