New U series from Npk
By Lindsay Gale20 March 2008
NPK introduced a new series of concrete crushers that offer 360 degree hydraulic rotation. Following on from the successful G-30JR, the five model U Series are said to be ideal for crushing and cutting walls, floors and light steel structures. U Series units can be carried by carriers weighing 18-50 tonnes, and weigh from 2,150-4,500 kg. The smallest, the U-21R, has a jaw opening of 800 mm, while the biggest in the series, the U-45R, provides a jaw opening of 1,130 mm. All feature NPK's integrated booster system, which automatically activates when the jaws meet resistance, resulting in faster cycle times and more crushing strength, claims the company.
