QTZ50(PT5010) Topless Tower Crane of Building Construction
TAVOL
84262000
Product Description
1-Product Description:
A compact tower crane shouldn't mean compromised safety. The PT5010 4-ton topless tower crane combines a small footprint with the same advanced technology as our big models: hydraulic self-erecting, frequency-converting slewing, and multi-layer safety devices including hoisting height limiter, slewing range limiter, and multifunctional limiter. Precise control of hoisting capacity, load moment, and trolley travel means every lift is accurate, while anemoscopes and obstacle lights prevent trolley axle and wire rope failures. With 4 tons capacity, 50 m jib, and 120 m anchorage height, it's the reliable, safe choice for smaller sites that still demand big-crane standards.
Tavol Tower Crane Core Advantages
High-Strength Structural Steel
Content: Built with premium Q345B/Q355B high-strength steel. Our mast sections and jibs undergo rigorous stress testing and robotic welding, ensuring exceptional structural stability and a longer service life in harsh construction environments.
Advanced Control & Safety Systems
Content: Equipped with an integrated black-box monitoring system and high-precision limiters for load, radius, and height. Our intuitive control system ensures smooth lifting movements and multi-layered safety for zero-accident operations.
Optimized Modular Design
Content: Features standardized mast sections and a quick-connection design. This modularity reduces transportation costs and significantly shortens the time required for site installation and dismantling, maximizing your project’s uptime.
