Structural features

1. Tower structure:
Square standard sections (1.5m×1.5m or 1.6m×1.6m) are used, connected by high-strength bolts, and have strong stability.
Independent height or attachment type (fixed to the building through wall attachment device) can be selected according to needs

2. Crane arm:
Horizontal arm and trolley variable amplitude design, flexible arm length combination (such as 40/45/50 meters).
The arm frame has a triangular cross-section, which reduces the deadweight while ensuring rigidity.

3. Lifting mechanism:
Equipped with variable frequency motor to achieve stepless speed regulation and smooth lifting.
The drum with large rope capacity is suitable for high-rise construction needs.

4. Slewing mechanism:
Planetary gear reducer + variable frequency control, smooth rotation and precise positioning.

5. Safety devices:
Standard torque limiter, weight limiter, height limiter, slew limiter, etc., in accordance with GB/T 5031 standard.
Visual monitoring system may be equipped (optional).

Application scenarios

Construction: Medium and large projects such as high-rise residential buildings, commercial complexes, bridges, etc.
Lifting operations: Material handling such as steel bars, formwork, and prefabricated concrete parts.
Adaptability: Suitable for dense construction sites, 50-meter arm length can cover a large operating radius.

Advantages and competitiveness

1. High cost performance: Between small, medium and large tower cranes, suitable for medium-sized projects.
2. Modular design: Easy to install and disassemble, and low transportation cost.
3. Energy-saving and efficient: Frequency conversion technology reduces energy consumption, low noise, suitable for urban construction.
4. Safe and reliable: Multiple protection devices to reduce operational risks.

Precautions

Foundation requirements: The concrete foundation needs to be designed according to geological conditions to ensure anti-overturning performance.
Wind speed limit: Wind speed in working state ≤20m/s, anchoring is required in non-working state.
Maintenance cycle: Regularly check the wire rope, bolt tightening and steel structure welds.
