Our diesel haulers are designed for maximum haulage capacity on difficult floor conditions or gradients. These haulers comply with new regulations pertaining to fire shutdown, exhaust emission sampling and brake standards, and utilize the same power package and drive components as the range of LHD machines. Features include a rugged, reliable drive unit with chainless drive system; quick response hydraulic steering and true tracking geometry for optimum maneuverability; and a turbocharged, after-cooled, 4-cycle diesel engine with 4-speed transmission with manual or electronic push-button powershift with forward/reverse mode.

They can travel and unload faster than shuttle cars, carry a 15-20% greater payload and operate in narrow roadways with tighter turns.
Each offers distinct advantages. All machines combine compact power, capacity and maneuverability with long-term availability and efficiency.
Many proprietary developments - such as dry scrubber and wet bath exhaust systems with diesel particulate filtration and horizontal or vertical configuration cooling radiators - make Cat diesel face haulers a safe and powerful solution for your room & pillar operations.
Like all components, our engines are industry-recognized and accepted. This means high quality, excellent spare parts support and, as a result, high service availability.
It is also designed to be cost-effective in operation and to meet the user's need for the safest maximum possible capacity, speed and power. Engineering excellence with computer-assisted, mine-specific design; Finite Element Analysis; quality assurance at every stage; and the use of high-performance components and materials ensure that your vehicle is built for long service life in the harshest of mining environments.
All vehicles are compliant with current and anticipated future safety requirements, such as exhaust filtering, falling object protection and maximized visibility.
Cat equipment is compliant with Australian Standard MDG guidelines, MSHA (USA), MA (China) and DGMS (India) legislative regulations for underground coal mining, including fire shutdown, exhaust emission sampling and brake standards.
The dry scrubber exhaust system features a dual independent cooling system with one for the exhaust system and another for the engine system, providing a balanced coolant flow through both systems. The wet-bath-exhaust-equipped machine has a single cooling system for the engine cooling and the exhaust gas cooled by constant consumption from the exhaust scrubber reservoir.
Easily accessible components such as the flame trap, exhaust filter and check points ensure that regular maintenance is a simple and trouble-free five-minute job for the operator. The FH125 D shares many components with other Cat vehicles, allowing reduced inventories of spare parts and consumables.
For safety, ease of maintenance and to reduce wear on the vehicle‘s drive train, the POSI STOP brakes are situated within the wheel hub. Locating the wheels equidistant from the articulation joint allows the FH125 D to offer true tracking four-wheel-drive, with front and rear wheels following the same path.
