Q1. What is the QTD800/50 Luffing Jib Tower Crane?
The QTD800/50 is a heavy-duty, high-capacity luffing jib tower crane with a maximum moment of 800 tonne-meters. Its defining feature is a hinged jib that can be raised and lowered (luffed), unlike the fixed horizontal jib of a hammerhead crane.
Q2.What size tower crane is it?
1.Max Load: 50 Tonnes
2.Jib Length: 75m / 80m
3.Tip Load: 4.5T @ 75m / 7.8T @ 80m tip
4.Free-Standing Height: 65.7m / 80.4m
Q3. Why is a Luffing Jib Crane So Important?
The luffing jib design solves critical spatial and safety challenges:
1.Operates in Extremely Congested Sites
2.Enables Multi-Crane Coordination
3.Provides Precision with "Level Luffing"
4.Offers High-Load Capacity at Height
Q4.Where is it Used?
1.Ultra-Dense Urban High-Rise Construction in city centers.
2.Infrastructure Projects near live roads, railways, or other structures.
3.Power Plant & Industrial Construction with complex layouts and existing infrastructure.
Any site with severe space constraints or multiple overlapping crane work zones.

Frequently Asked Questions
❓What does "Level Luffing" mean?
Level Luffing is an automated system where the crane's hoist and luffing mechanisms work in perfect coordination.
❓Why is it beneficial?
As the jib angle changes to bring the load in or out, the hoist automatically adjusts to keep the hook at a constant height. This allows for incredibly smooth, horizontal load movement, enhancing safety, precision, and speed, especially when placing heavy structural elements.
❓How does a luffing jib crane help with multiple cranes on one site?
Luffing jib cranes can raise their jibs to a steep angle, effectively operating within a much smaller circular footprint. This allows them to work closely alongside other cranes without risk of collision.
❓Can you provide installation and technical support?
Absolutely. We provide comprehensive support. Our team can deliver the crane and dispatch specialized engineers to your site to oversee the installation, conduct safety inspections, and ensure the crane is fully operational and your team is briefed.
❓What information do you need for a quotation?
Please provide the specific crane model (QTD800/50) and the quantity. For a detailed project-specific quote, information about your site layout, required heights, and load plans is also very helpful.
❓Are factory visits possible?
Yes, we welcome them. You are invited to visit our manufacturing facility to see our quality processes firsthand.
