沃尔沃建筑设备开发了一种旋转式铺管机附件，该装置使挖掘机也可以用作铺管机，为不想购买专用铺管机且一直使用常规挖掘机进行作业的用户提供了一种简单的解决方案。

“铺管机附件的目标客户是在空间有限的工地铺设管道的用户。我们的14吨挖掘机适合此类工作。”沃尔沃建筑设备附件和特殊应用产品经理Todd Cannegieter说，“如果您不经常从事管道铺设作业，也就不需要专用的管道铺设机或侧臂设备。我们希望为客户提供另一种选择。”

旋转式铺管机套件适用于传统的沃尔沃14吨履带式挖掘机-EC140EL和ECR145E。仅需将铺管臂连接到挖掘机的主臂，大约一小时即可从挖掘机转换为铺管机（反之亦然）。

这些组件坚固耐用，可以安全处理最大20英寸（508毫米）的管道，额定载荷为7300磅（3.3吨）。最大工作高度为24英尺（7.3 m），最大工作深度为50英尺（15.24 m）。运输时，配备了吊管机套件的挖掘机可在数分钟内准备好运输：只需要进行装卸操作，无需起重机或额外的人员，节省了时间和费用。

与传统的侧臂吊管机不同，沃尔沃获得专利的旋转式上部结构解决方案意味着该机器具有更大的机动性，而无需不断地重新定位其履带。短回转半径ECR145E可以在繁忙的两车道街道上执行管道铺设工作，同时留出一条车道供交通使用，非常适合在城市地区进行管道铺设。这种铺管机配置还为ECR145E提供了与其同级的标准挖掘机EC140EL相同的提升能力。

Volvo CE introduces rotating pipelayer conversion kits for 14-ton excavators

Volvo CE has developed a rotating pipelayer attachment kit that allows an excavator to also work as a pipelayer, offering a simple solution for users who don't want to buy a dedicated pipelayer and who have been using conventional excavators for the work.

"The pipelayer attachment kit is aimed at customers placing pipe in cities and municipalities where space is at a premium. Our 14-ton excavators are the right size for this type of work, so pairing the kit to these machines made sense," said Todd Cannegieter, product manager of attachments and special applications at Volvo CE. "If you're not lowering in pipe regularly, it can be hard to justify the investment in a dedicated pipelayer or side boom. We wanted to give customers another option."

The rotating pipelayer kit fits conventional Volvo CE 14-ton crawler excavators — the EC140EL and ECR145E. The pipelaying boom simply attaches to the main boom of the excavator, converting from excavator to pipelayer (or vice versa) in about one hour.

The components are robust and can safely handle pipes up to 20 inches (508 mm), with a rated load of 7,300 pounds (3.3 tons). Max working height is 24 feet (7.3 m) and max working depth is 50 feet (15.24 m). When it comes to transport, excavators with the pipelayer kit can be readied for transit in minutes: just load and go — no crane or extra people required, saving time, money and hassle.  

Unlike a traditional side boom pipelayer, Volvo's patented rotating superstructure solution means the machine is far more maneuverable, with no need to constantly reposition its tracks. The short-swing radius ECR145E can perform pipelaying work on busy two-lane streets while leaving one lane open for traffic, making it ideal for pipelaying in urban areas. This pipelayer configuration also gives the ECR145E the same lifting capacity as its standard excavator sibling, the EC140EL.

Unlike a side boom, the operator will always face the load, helping to reduce fatigue. An excavator-based pipelayer will also be more familiar to most operators, which could help with recruitment, training and productivity.       

Operators are further supported by Volvo's unique Load Moment Indicator, which ensures safe operation up to a 10° slope. The system monitors load weights and sends audio and visual alerts. It also includes a standard anti-two-block system.
