3. Material: All main chord be made of Q345B steel

4. Parameter: Maximum hoisting capacity 12 tons,the longest jib is 70m, maximum independent lifting height 60m, maximum attached height 200m

5. Model number: QTZ160

6. Application: Suitable for construction of medium and high-rise commercial, civil buildings and such large projects as roads and bridges, power stations, etc. as well as construction of large goods yard, wharf, etc.

Quick Detail:

1. The mast used monolithic standard section of 2,000mmX2,000mmX3,000mm.

2. The longest jib is 70m, the jib length combination reduces for every 5m and the minimum jib length is 45m.

3. The maximum hoisting capacity is 12 tons.

4. The maximum lifting capacity at a distance of 70m is 1.3 ton

5. The maximum hoisting moment is 185t.m.

6. The maximum free height is 60m and the maximum attached height is 200m.

7. Hoisting mechanism: Adopting a variable frequency motor   55KW for power

Slew mechanism: Adopting a torque motor    5.5 KWX2 for power

8. Luffing mechanism: Adopting a variable frequency motor   7.5KW for power

9. Tower crane foundation type: Leg fixing type

Competitive Advantage:

1. All structural parts adopt CO2 shielded for welding, having a strong penetrability , having a smooth surface and a high strength.

2. The main steel material has passed the mechanic test and chemical analysis to make sure the material without  internal defect.

3. Before paint spraying, the structural parts are subject to a shot blast treatment for more strength and relieving internal stresses and to ensure work pieces to have a clean surface and increase the adhesive force of paint film.

4.  Hosing mechanism adopts variable frequency motor with large diameter drum, large wire capacity. The wire performance is well to prolong the using life of the steel wire ;

The slewing mechanism adopts torque motor,  adopt RCV controller to realize the stepless-speed change,

Luffing mechanism adopts variable frequency motor and planetary reducer, all of the mechanisms which have compact structure, low noise, stable operation, high transmission  rate, braking is accuracy and reliable,maintenance is convenient.

5. Equipped various safety devices to ensure the operation reliably.
