10t Construction Tower Crane

As a traditional topkit tower crane engineered for large-scale construction sites, the ZJ6517 boasts key specifications: 65m jib length, 1.7t tip load, and 10t maximum capacity.

Structurally, it adopts high-quality Q345B steel, with key link pin shafts specially treated for salt resistance-ensuring a robust build and long service life. Its balance arm and jib connect to the tower cap via tie rods, a design that reduces boom weight, simplifies structure, and enhances stability compared to tower cranes without a tower cap.

Practically, the ZJ6517 offers extremely quick and easy assembly, plus strong, simple, and reliable lifting, slewing, and luffing mechanisms-ideal for heavy-load handling on construction sites.

Weight: the weight of underground section without load and ballast with longest jib and maximum free-standing height. 

1. Torque limiter: Control torque, it will warns when lifting weights reach to 90% of rated lifting torque. When reach to 110% of the rated lifting torque, it will limit rising upwards and trolley.

2. Weight limiter: Control the maximum lifting capacity, lifting weight reach to 40% of the rated capacity, limit high-speed lifting; lifting weight reach to 110% of the rated capacity, limit the lifting up.

3. Height limiter: Control the lowest and highest extreme position of lifting hook.

4. Slewing limiter: Control the extreme turns number of turn left and right.

5. Amplitude limiter: Control trolley limit position of inward and outward.

6. Overload protection: If the material is over the capacity, the crane will give a sharp warning for protection itself.

7. Emergency brake: If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure.

8. Main lifting motor with thermal protection and currency protection.
