Advantages of Dahan Luffing Jib Tower Crane

1. Since a mixture of argon and carbon dioxide is used as welding gas, our luffing jib tower crane come with great appearance and stable welding quality, even for large weld penetration.

2. The main structural parts of this lifting machinery, like single angle steel, are made of Q345 manganese steel which ensures strong environment adaptability.

3. Split mast sections are completely made through primary welding and then processing in CNC machining center. This will ensure high connecting precision and easy assembly.

4. Thanks to frequency converting system, the hoisting, slewing and trolleying mechanism of this luffing tower crane realize infinitely variable speed, thus considerably reducing impact load to these mechanisms, lowering variation of stress amplitude and improving fatigue life.

5. Hoisting mechanism adopts precision hardened gear reducer and zero-speed brake. So, its noise is greatly reduced. Particularly, hardened gear reducer ensures stable transmission, large bearing capacity, low noise and long service life.

6. In our luffing jib tower cranes, the electric cabinets are all equipped with Schneider contactors, circuit breakers and indicators which guarantee high quality as well as after-sales services.

7. Operator cabin of this heavy duty crane features large space. Toughened glass offers high safety and excellent vision. Internally installed electric cabinet is water and dust proof and has great heat dissipation.
