The following is a detailed introduction to the tower crane QTZ200 (w651510 or TC651510), which is a common flattop tower crane widely used in construction scenarios such as highrise buildings and bridges.

Model meaning

651510 (or TC651510):
QTZ: Chinese standard tower crane model prefix (Qcrane, Ttower, Zselfelevating).
65: Maximum working range (65 meters).
15: Maximum lifting capacity at the arm end (1.5 tons).
10: Rated lifting capacity at maximum independent height (10 tons).

Main technical parameters

Lifting performance:
Maximum lifting capacity: 10 tons (usually at the arm root, with a smaller range).
Minimum range load: 1.5 tons (65meter arm end).
Working range: 2.5 meters to 65 meters (the arm length combination can be adjusted according to needs).

Lifting height:
Independent type: about 51/60 meters (no need to attach to the wall).
Attached type: can reach more than 200 meters (by adding standard sections and wall attachment devices).
Lifting speed: 0100 m/min (continuous variable speed regulation by variable frequency).
Rotation speed*: 00.6 r/min.
Luffing speed: 2060 m/min (trolley traction type).

Structural features

Flat head design: cancel the traditional tower cap structure, reduce the installation height, suitable for group tower operations.
Modular components: standard sections, crane arms, etc. can be transported in sections, and onsite assembly is flexible.
Independent height: usually configured with 51/60 independent height, reducing early dependence on wall attachment.
Attachment spacing: generally set an attached wall every 2035 meters (specific calculation based on wind pressure resistance and load).

Power and control system

Motor power:
Hoisting motor: 55kW~75kW (frequency control).
Slewing motor: 5.5kW~7.5kW (with brake and buffer).

Safety devices:
Torque limiter, weight limiter, amplitude limiter, slewing limiter, etc.
Anemometer (recommended working wind speed ≤20m/s).

Application

Highrise buildings: construction of buildings over 60 meters.
Bridge engineering: prefabricated beam segment hoisting.
Industrial plant: steel structure installation.

Advantages and precautions

Advantages:
Large coverage, suitable for dense construction sites.
Flat head design reduces interference and improves safety.

Precautions:
It is necessary to strictly follow the load table to avoid overloading.
The location of embedded parts needs to be planned in advance for wallmounted installation.
