High Reliability, Low Cost
To ensure low life-cycle costs and high availability, all vehicles use tried-and-tested, commercially available powertrain components that offer high reliability and availability with high fuel economy.Components are of the highest possible quality and meet or exceed operational and design requirements. The use of reliable and powerful diesel engines ensures maximum power in a compact design.
Space is at a premium in underground roadways, so the vehicles are designed to be compact, with a minimal profile and roadway presence.They are also designed to be cost-effective in operation and to meet the user’s need for the safest maximum possible capacity, speed and power.
The Rapid Attach System (RAS) allows a range of accessories to be fitted, thus enhancing the flexibility of the vehicles in operation.RAS allows the use of accessories from forks and buckets to jib cranes and reelers, as well as many others.
Compliance to regional regulations and guidelines is achieved by using a variety of engine and exhaust conditioner packages.Cat equipment is compliant to Australian Standard MDG guidelines, MSHA (USA), MA (China) and DGMS (India) legislative regulations for underground coal mining. Caterpillar also supplies diesel equipment for non-coal mining applications.
Operator Safety and Comfort
The cockpit design features ergonomic, intuitive controls and optimum visibility and safety. This means that operators already trained on one machine can quickly learn to use the others in the range.All vehicles are compliant with current and anticipated future safety requirements, such as exhaust filtering, falling object protection and maximized visibility. Pilot hydraulic- and electronic-controlled vehicles are available with the option of dials and gauges or an LCD instrument cluster. Demanding working conditions require that the operator is comfortable for the entire shift, so suspension seats and restraint systems have been selected to assist in fatigue management and increase safety.
All machines can be supplied with various diesel engine packages suited to the customer’s requirements. Like all components, our engines are industry-recognized and accepted.This means high quality, excellent availability and economy of spare parts, and, as a result, high service availability. A broad range of mechanical and electronic engine packages are available, allowing vehicles to be tailored to specific applications or to meet regulations.
Caterpillar can offer the underground mining industry the choice of either a wet exhaust scrubber system or a dry particulate filter system. Both the wet and dry exhaust scrubbers employ a particulate filtration system with an inline purifier and catalytic converter.Caterpillar has designed a proprietary diesel exhaust solution to meet the highest emissions standards for the health and safety of personnel. The replaceable Cat particulate filter captures particulate matter, preventing its release into the mining atmosphere. A heat exchanger or wet bath scrubber is used to reduce exhaust-gas temperature and a catalytic converter reduces gaseous emissions. The exhaust system is monitored by the Cat DCS electronic shutdown system, which prevents the machine from being operated in unsafe conditions like low water levels or high exhaust system temperatures. Both dry and wet exhaust packages are approved for underground coal mine operation.
Caterpillar offers radiator units in either vertical or horizontal configurations.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 is cooled by constant consumption from the exhaust scrubber reservoir.
The base specification LHD electrics consist of four flameproof lights powered by a flameproof Cat alternator and a DCS intrinsically safe engine monitoring and shutdown system.
There are a number of additional options available for explosion or non-explosion protected machines that include:
- LCD graphical display in flameproof enclosure
- Dimming and directional control of the lights
- Solenoid-operated valve banks with spool monitoring
- Electronic shift transmission
- 12 V or 24 V electrical system
- Reversing camera and display in flameproof enclosure
- Electronic joystick control of hydraulics
Ease of Service
All Cat LHD machines can have their operation safety checks performed by the operator in minutes at the beginning of the shift.To return a high service availability, the equipment design has been aimed towards reducing machine downtime during maintenance and servicing tasks.
Rapid Attach System (RAS)
The RAS system makes an accessory change a safe, one-man operation, allowing a broad range of accessories to be fitted in moments without removing the backing plate or the operator having to leave the cab.A fifth-wheel trailer hitch can also be fitted so that the SH150 can be used for moving roof supports.

SH150 Roof Support TrailerThe SH150 roof support trailer turns your LHD into a high-speed shield hauler capable of carrying 50 tonnes (55.12 tons) and shields up to 2 m (6.56 ft) wide with an integrated hydraulic loading winch. The trailer is designed for moving roof supports and chocks. A hydraulic assist drive system can be fitted as an optional upgrade to support areas of inconsistent floor and roadway conditions for intermittent operation. A rated hydraulic winch is available for loading roof supports and two in-floor load positional cylinders can be used for assistance with unloading. With spring-applied hydraulic brakes and solid rubber wheels, the trailer is hydraulically lowered and raised for easy loading and unloading of transport. The trailer has a capacity of 30 000 or 50 000 kg (66,139 or 110,231 lb) and can carry a 2 m (6.56 ft) roof support. The SH150 can be towed by the CL210 and CL215.
General Purpose TrailerWith a tare mass of 3 tonnes (3.31 tons), the general purpose trailer can carry loads of up to 7 tonnes (7.72 tons). With a simple ladder-frame design, the width of the trailer can be selected to suit mine drive heading sizes. The flat deck and gate railing system allow flexible loading and unloading from either side with forks or handling devices.
Conveyor Structure ModuleFitting on top of a standard general purpose trailer, the conveyor structure module allows all components for a certain section of conveyor to be loaded and stored together. This modular approach not only speeds loading and unloading, but prevents damage to and loss of valuable components.
