The Hydrema 922G is a three‑axle, articulated dump truck built for demanding applications. With a powerful Cummins B6.7 Stage V engine delivering 314 hp (231 kW), a ZF ERGOPOWER automatic transmission, and a smart chassis design, it combines strength and agility. This machine is engineered for situations where both payload and ground sensitivity matter—featuring a low unladen weight, double hydraulic stabilisers, ±12° pendulum oscillation, and full operator ergonomics.
THE CABIN
The cab of the 922G offers premium comfort and safety. It has a spacious, easy-to-clean interior with two illuminated doors for safe access. The air-suspended and ventilated seat with integrated multi-joystick gives the driver comfort and control. The seat is multi-directionally adjustable and features both longitudinal damping and ventilation to maintain driver wellbeing. The operators cab is ROPS/FOPS certified with heavy-duty viscous suspension for less vibration.
The driver has easy access to all functions thanks to the ergonomic positioning, and the instrument display with data storage provides important information. An efficient air conditioning system, storage box and 12 V/24 V socket are standard. The computerised instrument display with data storage provides access to important information. The multi-joystick controls key functions with ease and efficiency, giving the driver full control with one hand. The 922G Series cab is not just a workplace; it’s a comfortable and productive environment that helps maximise performance on any jobsite.
SAFETY
TIPPING CYCLE
On the 922G, we have improved the tipping cycle to maximise efficiency. Our goal has been to make tipping fast and precise. The advanced 5-pump hydraulic system ensures that steering and tipping is done quickly and accurately. Separate pumps enable independent steering and tipping functions, meaning the dump truck can be positioned simultaneously with the tipping process.
The powerful tipping cylinders are well-protected and raise the load quickly thanks to their short stroke length, increasing productivity. The electronic power steering of the multi-joystick makes tipping smooth with soft starts and stops, and the auto-body-return system now includes automatic load lifting for more efficient tipping.
To improve safety, a tilt indicator in the instrument display (hoist-assist) alerts the driver with an alarm if tipping is unsafe. This contributes to safety and confidence while working.
RETARDER SYSTEM
Hydrema’s 922G impresses not only with its versatility and performance, but also with its upgraded retarder system that takes safety and braking performance to the next level. This upgraded retarder system is equipped with no less than 5 hydraulic pumps, ensuring that all functions of the 922G work independently with minimal energy loss.
The retarder system combines a powerful engine brake and a hydraulic retarder and is intuitively operated via a “retarder joystick” located in the right armrest. This advanced system significantly reduces the load on the service brake, especially when travelling down slopes and hills. This not only increases safety, but also extends the service life of the brakes.
As an added safety feature, the 922G also introduces a new brake indicator system, called the “brake care system.” This system is designed to monitor the brakes and alert the driver if there is a risk of overheating.
Service
One of the key factors in the efficiency and reliability of any machine is easy access to service and maintenance. Hydrema’s 922G has taken this principle to heart and offers an unrivalled service experience.
With a simple push of a button in the cab, you can open the hood for full access to the engine and various filters. The large hood opening makes it quick and safe to perform daily service checks and maintenance. This means you can optimise the performance of your machine without unnecessary delays or hassle.
Maintenance is essential for a long lifespan and prevents unexpected breakdowns. To ensure proper lubrication and minimal maintenance, there is even the option to add an optional automated central lubrication system. This system delivers the exact amount of lubricant to the different lubrication points and optimises lubrication intervals, making maintenance even more hassle-free.

The Hydrema 922G's chassis is at the heart of this dump truck, combining stability and precision to perfection. With an articulated chassis, +/- 12° oscillation angle, and double hydraulic stabiliser, it delivers exceptional stability. Constructed from high-strength steel with electro-hydraulic suspension and heavy-duty bogie axle, it's designed to tackle even the most challenging terrain. This chassis guarantees world-class reliability and performance.
The 922G's axles are the foundation of its impressive performance. The front axle is equipped with electro-hydraulic suspension and individual levelling, while the rear axle is a heavy-duty bogie axle with reduction gears in the hubs. This combination of technology and construction gives the 922G the stability and flexibility needed to tackle even the most challenging terrain, making it a reliable and versatile partner on any jobsite.
The Hydrema 922G's engine is at the heart of its power and performance. With an impressive Cummins B 6.7 litre 6-cylinder Stage 5 engine, it delivers a maximum power output of 231 kW/314 hp at 2200 rpm and a maximum torque of 1288 Nm at 1500 rpm. Equipped with DOC, DPF and SCR catalytic converter with AdBlue addition, it fulfils the strictest emission requirements while being fuel efficient.
The Hydrema 922G's fuel system has been carefully designed to ensure optimal efficiency and operation. With an impressive fuel capacity of 300 litres for diesel and 31 litres for AdBlue, both tanks are integrated into the front chassis for easy access and ease of use.
This dump truck’s braking and retarder system is tailored to deliver reliable and safe stopping power, no matter the working conditions. With a full 2-circuit braking solution and oil-immersed disc brakes on all 6 wheels, effective braking is ensured, and a fail-safe handbrake on the front axle adds extra safety. The retarder, which combines the engine brake and the hydraulic retarder, is manually operated and has a maximum retarder output of 300 kW/405 hp. This system gives the operator the necessary control and ensures that the Hydrema 922G can handle even the most challenging terrains and tasks with maximum safety and performance.
The system includes 5 hydraulic pumps that work together to power different machine functions.
Pump 1: 31 l/min constant pump for brake, stabiliser, differential lock and suspension.
Pump 2: 189 l/min variable pump: for articulated steering.
Pump 3: 195 l/min constant pump for tipping and retarder.
Pump 4: 195 l/min constant pump for extra retarder performance.
Pump 5: 64 l/min constant pump for emergency steering (wheel drive).
The Hydrema 922G is equipped with an impressive ZF ERGOPOWER 6 WG-210 automatic transmission with 6 forward and 3 reverse gears. This transmission is not only powerful, but also intelligent. It features 100% lock-up in all gears. And with both automatic and manual shifting options, you can customise your driving experience as needed. When it comes to speed, the 922G has a maximum speed of 50 km/h forward and 31 km/h in reverse. And with a maximum tractive effort of 223 kN, this dumper is ready to handle even the most demanding tasks with confidence.
The 922G is made for smooth manoeuvring on the jobsite, and steering plays a key role in this performance. With a servo-activated hydrostatic steering and a separate variable pump for the steering function, the operator has precise control of the machine. This allows a maximum steering angle of +/- 38° to be achieved, ensuring the 922G can navigate smoothly in even the most challenging environments.
