CRUSHING & SCREENING
The advanced diesel-electric drive system on the Metso Lokotrack LT400J enables lower fuel consumption and reduced operating costs.
operators before use. The EPS warranty on Metso equipment is a first in the industry and sets a new benchmark for crushing and screening equipment support. The Metso EPS warranty extends the standard factory warranty from 1-year/2 000 hours to 2-years/4 000 hours. The additional 3-year extension covers major components of the equipment for the full 5-year/10 000-hour period. Ease of product maintenance The machine has been designed for ease of use and maintenance. “Mobile crushers typically have extremely compact layouts, making machine maintenance challenging. In the case of the Lokotrack LT400J, the simplified hydraulic system and reduced number of oil-driven components ensure maintenance access and servicing become easier and more efficient. Technicians can easily access critical components for maintenance. For example, access to the front and under the jaw crusher is achieved simply by lowering the discharge conveyor to the ground. At the rear, the chutes can be hydraulically moved, allowing technicians to reach the back of the crusher quickly, safely, and without unnecessary effort. This thoughtful design reduces the time and complexity typically associated with maintenance access,” explains Warren. Further to this, the engine area is equally well designed. Gull-wing doors open fully to provide unobstructed access to the engine and generator compartment. This allows technicians to step into the engine bay, making inspections, servicing, and routine maintenance faster and far more convenient. The machine also incorporates Metso’s
proven liner handling arrangement, complete with dedicated slinging points for the safe removal and installation of liners. This system removes the need for unsafe lifting practices and ensures that maintenance can be carried out in a controlled and safe manner. “Inside the jaw crusher are two extremely heavy liners. On many conventional crushers, removing these liners can be a difficult and sometimes hazardous task because they are typically hooked into place and then bolted down. In some cases, operators must weld lifting lugs onto the liners to remove them, which introduces additional safety risks and wastes valuable maintenance time. With this machine, that process is completely simplified. A lightweight aluminium step is supplied so operators can safely enter the crusher chamber when installing the rigging equipment. The liners themselves are designed with pre-engineered lifting holes, allowing the supplied rigging equipment to be attached directly. The result is a much safer and far more efficient liner change process,” adds Warren. Concludes Marias: “When this is combined with the fuel efficiency improvements, the result is a machine that spends far less time standing idle for refuelling or maintenance—and far more time doing what it was built to do: crushing and producing.” Impressive features of the Lokotrack LT400J Robust and aggressive jaw crusher: • High efficiency electric motor with optimised flywheel inertia.
stockpiles allow for increased volumes of material to be stored on the ground. Fuel efficiency Metso’s next generation diesel-electric mobile jaw crusher is an impressive machine -relying on just 80 litres of hydraulic oil. Hydraulic oil is used to track the Lokotrack LT400J, operate the hydraulic rock breaker, adjust the discharge conveyor hights and adjust crusher closed side settings. All process functions like conveyors Metso C120 Jaw crusher, TK Grizzly feeder, magnetic separator and other systems are electrically driven. “On many older mobile jaw crushers, the oil volume is almost double the quantity of the new machine. The Lokotrack LT400J is largely electrically powered, it requires a CAT C9.3B 310 kW diesel engine that drives the onboard generator, thereby dramatically reducing fuel consumption and significantly lowering CO₂ emissions when operating in diesel mode. Alternatively, the machine can also be plugged directly into grid power,” says Marias. For the power challenged local market, the key advantage for many customers is fuel cost savings. To further improve operating efficiency, the Lokotrack LT400J is outfitted with a 1 000-litre fuel tank, allowing the machine to operate for up to 50 hours before refuelling. Downtime refuelling the Lokotrack LT400J is reduced with an onboard refuelling pump pumping at a refuelling rate of 80 l/min. This means less downtime, improved productivity and reduced operational delays. Impressively, the machine comes equipped with a 10 000-hour, five-year Equipment Protection Services (EPS) warranty, and extensive training for
• Hydraulic setting adjustment. • VFD as standard for easy cavity clearance. n
