Description
The Mini Tower Crane QTG10 is a lightweight internal-climbing tower crane featuring a compact design and stable, high-efficiency performance. Despite its small size, it delivers reliable lifting capability, making it an economical and efficient solution for building projects with limited working space. Known as the “Vertical Transportation Expert for Urban Sites,” this crane embodies five core strengths: precision, efficiency, safety, economy, and reliability.
Key Features of the Mini Tower Crane
1. Precision Frequency Control
Slewing and hoisting mechanisms use frequency-conversion motors. Stepless 0–0.6 r/min slewing and dual-speed hoisting (22/11 m/min) ensure smooth operation and accurate positioning.
2. Hydraulic Climbing Efficiency
The 0.4 m/min hydraulic jacking system enables steady internal climbing, minimizing vibration and cutting installation/dismantling time and costs.
3. Full Safety Integration
Equipped with anemometer, limit switches, solar safety lights, alarms, plus complete inspection and maintenance guidelines for lifecycle protection.
4. Compact & Energy-Saving Design
With 6 m max radius and 0.5 t rated load, this crane saves site space and reduces energy use for green construction.
5. High-Strength Structural Components
The precision-welded truss mast enhances torsion and bending resistance for long-term heavy-duty reliability.
