Topkit tower crane is the tower crane with tower head. The tower head is the fulcrum of tie-bars chains connected to jib and counter jib. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing invulnerability and lowers the weight of jib & counter jib (simple transforming beam in mechanical model). This type of tower crane is lower in production cost, but is more demanding on the erecting and dismantling circumstances. Furthermore, the tower crane occupies some vertical space, it turns out bad in anti-interference especially at tower crane concentrated working site.    

 Available Model: GHT5013-5, GHT5516-6, GHT6011-6, GHT6014-8, GHT5023-10, GHT6015-10, ect.

The following technical parameter is GHT5013-5, and it is used as a reference: 

We manufacture the topless tower crane, luffing crane, and derrick crane as well.

 Topless Tower Crane features novel design, scientific structure, high safety and reliability, good anti-fatigue and anti-shock. This crane has no jib tie-bars attached. Compared with topkit and luffing tower crane, Topless tower crane is bigger in jib section, simpler in stress, longer in lifespan of steel structure.  The installation and commissioning are made easy at top of crane to align with group working.  Jib section takes no-tie-bar design, which simple connection and easy disassembly.  The structural members are modularized with high production efficiency and short lead time to meet the customer’s demands to the max.

 Available Model: GHP5013-5, GHP5517-8, GHP6016-10, GHP6518-10, GHP6520-12, GHP7524-16, ect.

Luffing tower crane has special climbing system which makes the crane rise with building construction. The hoisting height improves by a large margin. It takes self-contained diesel dragging design and can hoist fast with load. In structure, the luffing tower crane’s wide range of elevation angle greatly improves the equipment capacity and working radius, which is very significant to main structural construction and the stand-out parts hoisting work.   The slewing radius of counter jib assembly is small and offer more options in case of group tower cranes work in limited city construction space. It is even the only option in city central area project and skyscraper building construction.

 Available Model: GHD4015-5, GHD4522-8, GHD5522-12, GHD6037-16, GHD6050-20, GHD60180-50, ect.
