QTZ80(5610) is a top-slewing, horizontal boom, self-erecting tower crane, which is widely used in high-rise buildings, bridge projects, power construction and other construction scenarios. Its model means:

QTZ: The pinyin abbreviation for "tower crane".
80: The maximum lifting torque is 800kN·m (about 80 tons·meter).
5610: The arm length is 56 meters, and the maximum lifting weight at the arm end is 1 ton.

Main technical parameters

1. Lifting performance
Maximum lifting weight: 6 tons (usually occurs at the arm root position).
Boom end lifting weight: 1.0 ton (at the 56-meter arm end).
Independent type: about 40 meters;
Attached type: can reach more than 200 meters (by adding standard sections and attachment devices).

2. Working amplitude:
Minimum amplitude: 2.5 meters (usually the distance from the center of the tower to the hook).
Maximum amplitude: 56 meters.

3. Lifting speed:
Three-speed/frequency control, usually 40~80m/min (no-load to rated load).

4. Slewing speed: 0~0.6r/min, stepless speed regulation.

5. Luffing speed: 20~40m/min (trolley traction).

6. Motor power:
Lifting motor: 30~45kW;
Slewing motor: 5~7.5kW;
Luffing motor: 3~5kW.

Structural features

1. Tower structure:
Adopting square section standard sections (such as 1.6m×1.6m), high-strength bolt connection, strong stability.
Can self-lift and add sections to meet different height requirements.

2. Boom system:
56m long horizontal boom, triangular cross-section truss structure, lightweight design.
Trolley luffing mechanism, precise control of hoisting position.

3. Jack system:
Hydraulic jacking device, which can realize the gradual increase or decrease of the tower body, safe and convenient operation.

4. Safety device:
Standard torque limiter, weight limiter, amplitude limiter, rotation limiter, etc., in line with GB/T 5031 standard.

Application scenario

High-rise building: Applicable to the construction of 6~40-story residential or commercial buildings.
Industrial plant: Large-span steel structure hoisting.
Infrastructure: Bridge piers, large equipment installation.

Technical Advantages

1. Efficient operation: Frequency conversion control improves operation stability and efficiency.
2. Flexible configuration: Optional independent or attached type to adapt to different construction stages.
3. Energy-saving and environmentally friendly: Low noise design, in line with modern construction environmental protection requirements.
4. Easy maintenance: Modular design, key components are easy to repair and replace.
