1. The lifting boom and balance boom adopt cantilever boom
structure, which reduces the hoisting modular and makes it more
safe, convenient and flexible to install and uninstall, and reduces
the requirements for hoisting equipment and the site. 2. Multiple
special mounting brackets are available, which saves the
installation time and ensures safe and quality installation. 3. The
lifting boom adopts cantilever boom structure and variable
cross-section materials, featuring more reasonable structural
stress and long service life; And it is easier to make different
combination of boom length. 4. It adopts standard sections (for
models of over 12t) of piece assembly structure, split structure
stock, and assembled platform, which meet the transport
requirements for standard container. 5. The extra-long boom is
designed with a rope-supporting trolley, and the speed of which is
1/2 of that of the luffing trolley, which can achieve the most
optimum rope-supporting effect. The structure has applied for
national patent. 6. The lifting mechanism adopts speed regulation
by frequency control or by eddy current brake series resistance,
featuring good lifting performance; The slewing system adopts
frequency control by torque electric motor or by coil winding type
electric motor with hydraulic coupler, featuring smooth operation
and small slewing impact. 7. All kinds of safety devices are
reliable and easy to adjust; Both the safety monitoring control
system and traditional safety system are available, the double
system ensures safety operation of the tower crane; The hydraulic
system adopts low/medium pressure design, featuring higher safety
and reliability. ModelMax.lifting capacity & work rangeMax.work
