HansKünz为集装箱起重机市场推出了一种新概念,单梁式A型腿结构的RTG。起重机类似于在马士基摩洛哥的Tanger Med码头开发的新型ASC,但采用16轮驱动的轮胎式大车运行机构。

       Freerider采用了一种称为“Spider”的新型8绳起升防摇系统,其中8个齿轮马达驱动8个独立的绳筒,直接旋转至头块。这实现了一个非常坚硬的绳索塔,作为一个机械防摇系统,可以同时移动所有六个自由度的负载。可以实现全方位高达300mm的微动Trim/List/Skew 5度移动。

       另一个独特的功能是全新的one hand控制系统,其中单个操纵杆通过定向移动控制器来控制所有的起重机行程运动,并通过升高和降低相同的旋钮来控制起升机构运行。

       使用椭圆形A型腿和单梁可以降低起重机结构的重量,同时增加刚度。大车行驶速度为130/160m/min,带载和不带载,堪称当今市场上最快的。

      Freerider的设计从一开始就考虑到自动化,作为后方堆场装载模块中ASC的替代方案。这意味着RTG可以利用其现有的RTG跑道转换为自动化操作,而不会降低堆叠容量,也不需要大量的土建工程(电气化和转换区域的创建除外)。

       Freerider作业区域相当于5 + 1到9 + 1,堆叠高度从1over4到1over6。电源可以选择电缆卷筒,滑触线,柴油发电机或混合动力驱动。Kuenz这种结构设计有如下优点: 

■风载荷降低约65%

■正常迎风作业,大车驱动电机功率降低约65% 

■ 减少能量消耗

■ 减小车轮、钢结构及起重机轨道上的动载荷(车轮动态轮压、钢结构风载荷、若为RMG可减少轨道侧向载荷)

降低整机自重10%: 

■ 降低轮压15%

■减少大车车轮数(RMG)

■减少焊接工作量,特别是筋板焊接。

    基于如上特点明显减少制造成本,降低码头建造和使用成本,显著提高产品竞争力。


Künz launches RTG at TOC Europe

The new “Freerider” RTG features a unique, aerodynamic single girder and a new hoist system.

Hans Künz has unveiled a unique new concept for the container crane market, an RTG with a single girder and an A-frame leg structure. The crane looks very similar to the new ASC Künz developed for APM Terminals’ new facility at Tanger Med in Morocco, but running on rubber tyres with a 16-wheel drive system instead of crane rails.

The Freerider features a new 8-rope hoist system called “Spider”, where eight gear motors drive eight separate rope drums that are reeved directly to the headblock. This achieves a very stiff rope tower that acts as a mechanical anti-sway system and can move the load in all six degrees of freedom simultaneously. Micro motion of up to 300mm in all direction can be achieved, along with 5 degrees of movement in the trim, list and skew directions.

Another unique feature is the new “One Hand” control system, where a single joystick controls all the crane travel motions by directionally moving the control know, and the hoist by raising and lowering the same knob.

Using A-frame legs and single girder enables Künz to lower the weight of the crane structure, while increasing stiffness. Gantry travel speeds are 130/160 m/min, with and without a load, which Künz says is the fastest available on the market today.

The A-frame leg structure means there is no clear portal for the trolley to enter at the end of the main girder in the reverse trolley travel direction. Künz has compensated for this by moving the cab more towards the centre of the spreader, and adding a camera system for a view of the working area when obscured by the spreader.

Freerider was designed with automation in mind from the outset, as an alternative to ASCs in an end loaded block configuration. This, says Künz, means RTG terminals can convert to automated operations using their existing RTG runways, without a loss of stacking capacity, and without significant civil works (except for electrification and the creation of transfer zones).

 Freerider is available in widths equivalent to 5 + 1 up to 9 +1, and stacking heights from 1-over-4 to 1-over-6. Power supply options are a cable reel, conductor rail, diesel generator or a hybrid drive.
