Hydrostatic Drive
Our unique hydrostatic drive solution uses a centrally mounted gearbox, providing superior traction and braking. This design also reduces flange wear and improves handling in curves. The stub axle system keeps the wheel loads independent of the drive loads, maximising lifespan and providing a much more reliable solution than traditional wheel motors.
User-selectable drive modes for work, travel and creep allow the machines to be adapted to different operating conditions, maximising productivity and reducing operator workload.
Control Systems
AJH's control system utilises an IFM visual display which can be programmed to control multiple features of the machine.
Work Modes
User-selectable modes allow tuning of the system when travelling, working or fine control is required.
Bucket Diverter
Allows the user to seamlessly control hydraulic diversion for different machine attachments.
Trailer Air Brake
The compressor and brake control system is seamlessly managed to ensure optimal performance and minimise power consumption when operating air-brake trailers.
Control Systems
Steering Locks
Our machines are fitted with a steering lock safety system to prevent the steering of the road axles when the rail are engaged keeping the machine within gauge.
Rail Axle Deployment
Through the control system the rail axles can be deployed induvidually for complete control.
Rail Axle Brake Test
For improved confidence, our safety system comes available with a brake test function when working on rail (Only available for hydrostatic rail axles)
InTeEx
The InTeEx Rail Rated Capacity Indicator (RCI) System is a cutting-edge safety solution explicitly designed for road-rail excavators, ensuring safe and efficient lifting operations in railway environments. This system provides real-time monitoring of load capacities, machine stability, and operational parameters, preventing overloading and reducing the risk of tipping or structural strain. With an intuitive interface, the InTeEx Rail RCI system delivers precise weight calculations and audible and visual alerts when approaching operational limits. Its seamless integration with the machine’s hydraulics allows for automatic intervention, ensuring compliance with industry safety standards and Network Rail regulations. Designed for reliability in demanding rail applications, the InTeEx Rail RCI enhances operator confidence and overall project safety.
GKD
The GKD Rail Rated Capacity Indicator (RCI) System is an advanced safety and control solution designed to enhance the operational efficiency and security of rail-based excavators. This system continuously monitors load weights, machine stability, and operational limits to prevent overloading and unsafe lifting conditions. With real-time data feedback, the GKD RCI provides operators with precise, on-screen alerts and automatic intervention if safety thresholds are exceeded. It integrates seamlessly with the excavator’s hydraulic and electronic systems, ensuring compliance with industry regulations and minimising the risk of accidents. The system is crucial for ensuring optimal performance in railway maintenance, trackside lifting, and infrastructure projects, providing peace of mind to operators and project managers alike.
IoT Portal
We can equip your machines with our IoT suite, giving you access to a powerful online portal packed with real-time insight into your fleet. View live GPS location, set up Geo leashes to define operational boundaries, and record machine-specific data such as fuel usage and error codes. For even greater visibility, add-on health monitoring equipment enables predictive maintenance functionality — identifying potential issues before they become costly failures. All of this data can be leveraged to reduce operating costs, minimise downtime, and improve the long-term reliability of your machinery.
Offset Boom
The RH925 offset boom configuration provides enhanced reach and flexibility by shifting the boom laterally from the machine’s centre line, allowing operators to work closer to walls, foundations, and tight excavation boundaries without constantly repositioning the unit. This offset geometry improves visibility, enables more precise digging in restricted spaces, and supports efficient trenching or grading alongside obstacles. It’s a practical option for contractors who need controlled, side‑aligned excavation where a standard boom layout would limit access.
