Liebherr Introduces Plug-In Gearbox Series
March 21, 2012—In the first half of 2011 Liebherr successfully introduced a new series-produced range of slewing gearboxes. Now, the company has developed a standard range of planetary plug-in gearboxes and added a new product to the range of Liebherr gearboxes. Planetary plug-in gearboxes are designed for installation in winches. They are of particular interest to companies that want to purchase winch drums and frames separately or manufacture them themselves. The new range includes a total of 14 sizes from the PEG 250 to the PEG 1100, which are available in a wide range of ratios from i=50 to i=700. The smallest gearbox has a dynamic torque of 8,500 Nm and the largest can produce a dynamic torque of 700,000 Nm (with load spectrum L2, operating class T5, categorised according to FEM). The series-produced gearboxes designed for horizontal installation in winches can be adapted for drives powered by both electric and hydraulic motors and are thus very flexible.
