How to Dismantle a High-Rise Tower Crane? Meet the Derrick Crane TD1540-4

Q1: What is a Derrick Crane used for in modern construction?

A: A derrick crane is specifically designed to be assembled on the rooftop of a building to dismantle inner climbing tower cranes once their job is finished. Because it can be brought up in smaller pieces and assembled on-site, it acts as the vital bridge to safely lower heavy tower crane components back to the ground.

Q2: What are the key lifting specifications of the TD1540-4 model?

A: The TD1540-4 is engineered for optimal balance between agility and strength on rooftops. Its core specs include:

Maximum Lifting Capacity: up to 4 metric tons ($4\text{t}$) using a two-fall wire rope configuration.

Single-Line Capacity: up to 2 metric tons ($2\text{t}$) using a one-fall setup for quicker line speeds.

Maximum Reach (Jib Length): a generous 15-meter operational radius to clear building edges smoothly.

Q3: Why is the "Tip Load" capacity of this crane so unique?

A: Unlike traditional cranes where lifting capacity drops sharply as the hook moves further out, the TD1540-4 maintains a flat load curve. It can lift its maximum 4.0t load even at the absolute tip (15m radius) when properly configured, offering incredible stability and safety for operators handling heavy loads near the building edge.

Q4: What makes our Derrick Crane TD1540-4 the preferred choice for contractors?

A: We focus on safety, versatility, and efficiency.Flawless Tip-Load Performance:

The ability to carry full weight at maximum outreach eliminates risky operational guesswork.

Flexible Luffing Ranges: The jib can safely luff between $15^\circ$ and $75^\circ$, giving operators precision control in tight rooftop spaces.

Compact Footprint: It features an optimized structural design (with a $180^\circ$ slewing degree arc) that securely anchors to rooftops without overloading building slabs.

Reliable Power Options: Built to seamlessly integrate into standard project grids with $380\text{V}$, $50\text{Hz}$ / $440\text{V}$, $60\text{Hz}$ power compatibility.

Q5: Is it easy to transport and assemble on top of a skyscraper?

A: Absolutely. The entire crane is highly modular. Components like the jib sections, mast, and pillars are designed to fit into standard construction hoists or service elevators, making transport to the roof hassle-free.
