Next-generation Lokotrack LT400J delivers high-output, energy-efficient primary crushing to Africa

Africa’s mining, aggregates and construction industries are set for a major operational uplift with the introduction of the Metso Lokotrack LT400J, now available through Pilot Crushtec. Designed for high-capacity performance and enhanced efficiency, this next-generation mobile jaw crusher signals a significant step forward in crushing technology across the continent.

According to Charl Marais, the LT400J represents the evolution of the Lokotrack EC range, combining robust mechanical design with a modern diesel-electric drive system to deliver improved fuel efficiency and reduced operating costs.

“The LT400J is designed as a true production machine,” Marais says. “It is built to run for long periods with minimal interruption, while maintaining high throughput and reliability in demanding applications.”

With production rates ranging between 300 and 600 tonnes per hour, the machine is well suited for primary crushing applications in mining, quarrying and recycling. Its ability to sustain long operating cycles while maintaining energy efficiency makes it a compelling solution for high-demand environments.

A key feature of the LT400J is its adjustable C120 jaw crusher, which includes three nip angle settings to optimise material flow and improve linear utilisation across varying feed conditions. This adaptability ensures consistent performance regardless of material type or operational demands.

Fuel efficiency is another standout advantage. The machine can operate for up to 50 hours before refuelling, significantly reducing fuel consumption compared to conventional diesel-hydraulic systems. Operators also have the option to connect directly to grid electricity, further lowering emissions and operating costs.

Wayne Warren highlights the benefits of the machine’s electrically driven process functions, which enhance stability and performance consistency.

“Electric drive systems maintain stable performance regardless of temperature variations, as there is less efficiency loss associated with hydraulic oil heating or component wear,” Warren explains. “This translates directly into improved operational consistency which is a key factor in maintaining steady production rates.”

One of the most notable advancements in the LT400J is its upgraded digital control architecture. The redesigned remote-control system now features an LCD screen, allowing operators to monitor machine functions in real time and make adjustments directly on-site.

This innovation eliminates the need for two-person coordination during setup and operation, improving both safety and efficiency. It also aligns with a new generation of operators who are more familiar with digital interfaces and intuitive control systems.

Marais adds that the machine incorporates an advanced remote monitoring system with increased sensor integration.

“There is a higher level of feedback from the machine,” he says. “That allows operators to adjust parameters such as crusher settings and conveyor positions without physically intervening which is a significant time-saver and an added safety benefit.”

These digital capabilities enable better preventative maintenance, faster troubleshooting and reduced downtime, ensuring more consistent production performance over time.

To support the rollout of this advanced technology, Metso has worked closely with Pilot Crushtec to provide specialised training. At the company’s Jet Park facility, senior Metso technicians conducted in-depth sessions with local teams to ensure readiness for operation and maintenance.

“Working directly with the factory specialists allows our technicians to fully understand the machine, its capabilities and its complexities,” Warren says. “With any new generation machine, there is always an element of training.”

Beyond performance, the LT400J also introduces practical design improvements aimed at simplifying maintenance and enhancing safety. The redesigned discharge conveyor can be adjusted to three different angles, allowing for flexible stockpiling, efficient material transfer or easier maintenance access.

Additional features such as improved liner replacement systems, hydraulically adjustable bypass chutes and enhanced engine access through large gull-wing doors contribute to reduced service times and improved machine availability.

The machine’s track-mounted mobility further enhances its value, enabling rapid relocation across sites and allowing operators to adapt quickly to changing production demands.

With its combination of high throughput, energy efficiency, advanced digital controls and operator-focused design, the Metso Lokotrack LT400J positions itself as a powerful solution for Africa’s evolving mining and aggregates landscape.
