Technical Parameters
Products Description
The QTZ200 (ZJ7020) tower crane 18t tower crane features stable operation and reliable management due to the adoption of various advanced technologies. It is easy for this heavy-lifting equipment to control the hoisting capacity, load moment, and trolley traveling range more precisely. Max capacity is 10t, jib length is 70m, and tip load is 2t.
Construction companies use building construction hammerhead tower cranes to lift heavy materials such as steel and concrete. These giant hammerhead tower cranes can often be seen in cities, rising hundreds of meters in the air to construct huge skyscrapers.
1. Suitable for occasions with special height requirements, such as near airports, tunnels, workshops, and high-voltage cable construction sites.
2. It is suitable for construction sites that require a lifting arm. It can be used as an interior climbing crane in high-rise buildings, irregular roofs or small areas. It is very convenient to disassemble in restricted construction sites, and each boom only needs to be disassembled manually once.
3. The steel structure of the crane boom has a long service life and high safety standards.
4. The boom has good applicability and a high utilization rate. The design of the flat-top tower crane boom is easy to achieve serialization and standardization, reducing design and manufacturing costs. The design cost is low, the cycle is short, and it can better meet the various needs of customers.
Advantage
1. The crane has complete safety devices to ensure safe and efficient operation of the crane. The crane is equipped with a lifting height limiter, trolley stroke limiter, torque limiter, weight limiter, etc.
2. The boom has good stability and a large combined amplitude range.
3. Suitable for construction in situations with special height requirements.
4. Large lifting capacity, effectively solving the high lifting capacity requirements of high-rise steel structure construction team cranes.

Weight: the weight of the underground section without load and ballast with the longest jib and maximum free-standing height.
Usage Process
1. Automatic detection of braking force: Before the tower crane is started every day, the system automatically performs braking force detection. The complete brake check logic test can effectively detect faults in the electrical and brake mechanical systems, and ensure the safety of the tower crane to the greatest extent.
2. Hook detection and automatic control function: When shutting down, the frequency converter will continuously detect whether the braking mechanism is abnormal and whether the braking mechanism is normal. When the hook slides down frequently, the system automatically starts the frequency converter to pause the weight (rise at a very low speed) and report the fault, reminding the driver to safely lower the weight to the ground.
3. Understand the construction site procedures
Crane operators are responsible for following certain rules to ensure safety. They can avoid potential dangers through radio communication and pay attention to the gestures of other workers to ensure safe lifting. It is essential to track all information provided by the control system.
Mechanics should be proficient in using the joysticks and other controls in the cab to perform all operations correctly. Monitoring load and wind speed is essential.
