1Crane Cabin
Designed with your crane operator’s comfort in mind, enjoy a broad perspective with big glass windows and user-friendly elements including a fire extinguisher, air conditioning, wipers, and coat hooks.
-
2Working Platform & Guardrails
Hot-dip galvanized guardrails, ideal for whatever environment you come across, provide exceptional corrosion resistance and weatherability.
-
3Standard Tower Section
Designed with high-strength steel construction for great load-bearing capability, wind resistance, and corrosion resistance guarantees your crane functions remarkably under all conditions.
-
4Slewing Assembly
Provides outstanding stability, low maintenance, quick transportation, and installation for your rigorous operation requirements.
-
5Tower Crane Trolley
Using a trolley that runs along the jib track will maximize your operating range and give efficiency and flexibility for lifting.
-
6Crane Hook Block
Built of high-strength steel hook block with outstanding load capacity, corrosion resistance, and longevity, giving you confidence in every lift.
-
7Hoist Gear Assembly
Using a hoist gear assembly with high rope capacity will help you to achieve effective lifting and provide you better stability and control during operations.
-
- 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.
Safety and Reliability
-
- 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.
Upgraded Coating
-
- 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.
Superior Operability
-
- 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.
User-Friendliness
The lifespan of a tower crane depends on a variety of factors, including frequency of use, maintenance level, and build quality. With proper maintenance, the tower crane can last 15 to 20 years.
Tower cranes have a maximum wind speed limit, beyond which they cannot be operated safely. Operators should always comply with local safety regulations, and our cranes are designed for a maximum working wind speed of 20m/s.
Yes, we provide the option of custom colors and designs to match the requirements of a specific project or company brand.
