A reliable and efficient mobile crushing plant is a sum of several factors working together smoothly, which is well illustrated on Metso Mobile’s latest and most advanced track-mounted jaw crusher plant, the Lokotrack LT120.Significantly, the Lokotrack LT120 uses the same field-proven technology seen in Metso’s tracked units for over 26 years “Building on this track-record, the LT120 combines crushing performance and user-friendly design in a new, revolutionary way,” points out Andrew Stones, sales manager for Barloworld Equipment’s Metso Mobile division (Barloworld Equipment is Metso Mobile’s Southern African dealer). “A giant leap, for example, was taken in the bracket and damper design to ensure incredibly smooth operation.” The new on-board C120 jaw crusher, with its feed opening width and depth of 1 200 and 870 mm, respectively, provides excellent capacity even in the toughest applications and is optimally designed to meet the requirements of aggregate producers, medium- and large-scale contractors, and mining concerns.
Metso’s primary targets in developing this unit are safety, reliability, simplified maintenance, energy efficiency and long operational life.Good examples of in-built safety on the Lokotrack LT120 include sturdy, easy-to-open composite flywheel guards, and hydraulically folding and locking feed hopper sides. Additionally, jaw die bolts are readily accessible. “The result of in-depth field research, the C120 comes equipped with a large feed opening, a very aggressive cavity nip angle and an extremely long stroke in the bottom of the cavity to achieve the highest possible capacity in its class. Plus for the first time, the same Lokotrack model is available either as a hydraulically or electrically driven option,” Stones continues. Power delivery on the hydraulic version is provided by a 310 kW Cat C13 engine. In turn, the Lokotrack LT120E electric powered unit sources its energy from an external supply or a 420 kV on-board diesel generator, depending on the preferred configuration set-up. The operating weight on the LT120 and LT120E are 57 and 63 t respectively, with the same compact dimensions for road legal low-bed transportation.
