Hoisting jibs are efficient and widely applicable. The flat top tower crane is designed to break into modules that make it easier to adjust to the size you need for your specific job. It also makes these topless tower cranes more affordable, interchangeable, and easy to transport. The end jibs of large capacity flat top tower cranes can be used as middle or base sections.
Features of the Flat Top Tower Crane
1. When the topless crane stands alone, it includes 1 basic section (height 7645) and 13 mast sections (height 3000).
2. With attachments, the construction machinery can reach a maximum height of 1 basic section (height 7645) and 58 mast sections (height 3000).
3. At maximum height, the tower crane needs 5 collar ties, the distance between each collar tie being 27000, and the first collar tie at height 36.42m, max. Height should not exceed 42m.
4. The mast section LxWxH: 2000x2000x3000, material is L200×200×20.
5. The jib has 10 sections (9mx6 5mx3 1.6m), size of dimension width x height (center distance) 1600x1500, upper and lower chord use angle steel button squares, separately use L100×100×10/ 8 and L80×80×6.
6. Height of tower crane head is 9000, material is L125×125×12 button square.
7. Main stressed force material is Q345B.
8. Main low pressure electric parts are from Schneider, frequency from Yaskama, PLC from Mitsubishi.
