Key Features
    • Flat-Top Tower Cranes

      Safety and Reliability

      • The load limiter and lifting torque limiter are two overload prevention devices that help to prevent tower crane overload and overtorque.
      • Double amplitude (stroke) limiters and triple lifting height limiters help you monitor and control lifting height, therefore avoiding crane collisions.
      • Enjoy the security of a frequency converter in the electric control system for sophisticated anti-drop hook detection, which guarantees smooth lifting and stopping for greater efficiency and safety.
      • Large platforms and inclined ladders on our tower crane help to prevent falls.
      • Experience stability during operations. Jacking is done without slewing, ensuring balance without tilting during construction, enabling mounting and dismounting without falling, and preventing unintended slewing.

      Upgraded Coating

      • With our double-component paint on structural components, you are guaranteed a rust-free structure for five years.
      • Components like platforms, ladders, and railings undergo hot-dip galvanizing to ensure you get lifetime rust and corrosion prevention as well as anti-slip features.
      • With automotive-grade spot welding and electrophoresis technology, our crane's operator's cab is created in a single stamping process, letting you enjoy no rust for a decade.
    • Flat-Top Tower Cranes

      Superior Operability

      • The frequency conversion slewing technology will enable you to turn on and off with no vibrations and zero swing during stops, so producing instantaneous response.
      • With millimeter-level slow-speed positioning and a minimum of 5mm/s, which allows exact control, precision is right at your hand. The system reacts right away and the operator can employ jogging control on the handle.
      • With the sophisticated detection of the electric control system, your lifting speed adaptably changes: heavier loads hoist slower, lighter loads lift faster.
      • During crane slewing, the system prevents the jib and hoisting wire rope from swaying side-to-side. It stops jib and hoisting wire rope from forward and backward swaying during luffing operations. Should fast stopping be needed during slewing, the operator can rapidly stop the crane's rotation by means of reverse handle operation.

      User-Friendliness

      • Integrated assembly in the factory simplifies your logistics by means of professional loading and unloading plans, therefore minimizing packaging units and transportation vehicles.
      • Using maintenance-free lubricating oil in the hoisting mechanism will help to reduce maintenance and workload.
      • Increase efficiency and save time with our pre-calibrated electronic load limiters ready for use without field calibration on-site.
      • Enjoy great adaptability with counterweights; models in their series such as 6013, 6513, 6515 have interchangeable counterweights within their series. The same holds for 7521 and 7527.
FAQs

It uses a fixed base and an extendable jib to drive the lifting and slewing mechanism to complete the vertical and horizontal transportation of goods.

Regular inspections and maintenance are necessary, including lubricating moving parts, inspecting and replacing worn parts, ensuring that safety devices are functioning properly, etc. We have a professional repair team to provide maintenance support and service.

Consider factors such as building height, construction environment, lifting needs, and budget. We can provide professional advice to help you make the best choice.
