Robot double from Husqvarna
By Lindsay Gale25 June 2013
Husqvarna Construction has added two new demolition robots to its existing three model line-up discussed in the last issue in the form of the 1,750 kg (3,850 lb) DXR 270 and the 1,960 kg (4,312 lb) DXR 300. Commenting on the launch of the two new 1,000-2,000kg robots, Husqvarna believes it is now able to offer its customers a complete series of remote demolition robots. Husqvarna global product manager Lars Gustafsson said: “We can now offer customers robots in the 1,000–2,000 kg range, depending on the needs of the customer.
He said of the smaller DXR 270: “We have developed DXR 270 because we have seen a demand for lighter units in this segment. With its compact design and low weight, it is easy to transport as it fits through all normal doorways and can be transported in most lifts, while the larger DXR 300 is only 78 cm wide. That means it will fit through most doorways and construction lifts, making it suitable for diverse applications within the construction area,”
The 19 kW DXR 270, along with the 300 and 310 machines, features new outriggers with a wider 160 cm (64 inch) span to provide increased stability but also allow the machines to carry a greater payload.
According to Husqvarna, its fixed boom arm design is stable, durable and requires minimal maintenance, and delivers precise tool positioning while the machine is working. Its low height provides a clear view of the tool for the operator while the machine is being worked while further enhancing stability. As with the company’s other robots, the machine is controlled by a modular CAN based PLC that is easy to use and features a 8.75 cm (3.5 inch) colour display. It has a reach of 5.2 m (17 ft).
The 22 kW DXR 300 has a reach of 6.2 m (20.4 ft) and uses the same control system as its smaller brother. Thanks to the new outriggers, it can carry in excess of 400 kg (880 lb), and according to the company, is ideal for concrete and brick demolition applications in staircases, roofs and balconies as well as sensitive locations such as courtyards.
