In the fast-paced and space-constrained environment of modern urban construction, selecting the right lifting equipment is critical to project success. The Derrick Crane TD4030-20 has emerged as a standout solution, consistently proving its mettle on complex job sites.
Strategic Role & Key Functions
The TD4030-20 is a versatile tower crane designed to tackle the core challenges of urban builds: lifting heavy materials to significant heights within a tight footprint. Its primary function is to provide reliable, high-capacity lifting across a wide working radius, essential for erecting structures efficiently and safely.
Why the TD4030-20 is a Project Game-Changer？
1.Exceptional Capacity & Reach
2.Adaptable & Space-Efficient Setup
3.Superior Operational Flexibility
4.Engineered for Reliability
Direct Impact on Project Success
Contractors using the TD4030-20 report transformative outcomes:
Accelerated Timelines: Efficient lifting cycles and reliable performance keep critical path activities on schedule.
Enhanced Site Safety: Predictable load handling and stable configurations, validated by clear load diagrams, minimize operational risks.
Cost Optimization: Reduced need for auxiliary cranes, lower foundation costs due to flexible footprints, and high reliability contribute to significant overall cost savings.
Solving Urban Logistical Puzzles: Its ability to operate effectively in extremely tight spaces, often surrounded by existing infrastructure, has been highlighted as its most valuable asset.
Voices from the Field: Customer Feedback
"The flexibility in foundation size was the deciding factor for our site. The TD4030-20 fit where other cranes couldn't."
"The clarity of the load charts and stability data gives our site engineers and operators immense confidence. We know exactly what it can do at every radius."
"A workhorse. It manages our daily material demands—from concrete to reinforcement—without faltering, keeping the entire project moving."
"The multiple hoist fall options let us optimize for speed or weight dynamically, which is a huge efficiency booster."
Frequently Asked Questions (FAQ)
Q: What is the maximum load capacity at the minimum radius?
A: The TD4030-20 can lift up to 20 tonnes at its minimum working radius.
Q: Can this crane be used on very small sites?
A: Yes. One of its key advantages is the ability to be installed on a compact 4.0m x 4.0m foundation (center distance), making it suitable for tightly constrained urban locations.
Q: How does the hoist speed vary?
A: Speed is inversely related to capacity via the fall system. For example, in 4-fall mode, it can lift 10t at 35 m/min, while in 2-fall mode, it can lift 5t at 70 m/min, offering great operational flexibility.
Q: What power supply is required?
A: It requires a standard 380V, 50Hz power supply (also compatible with 440V, 60Hz) with a recommended supply capacity of approximately 130 kVA.
Q: Is it suitable for high-rise construction?
A: Absolutely. With a free-standing height of over 40m, substantial hoist drum capacity (800m of rope), and strong load performance at longer radii, it is an excellent choice for mid- to high-rise urban buildings.
