The 922HM is a 20‑ton dump truck engineered for challenging terrain and sensitive surfaces. With a Cummins B6.7 Stage V engine delivering 314 hp (231 kW) and torque of 1,288 Nm, it combines power with efficiency. The larger 800 mm tyres increase clearance and reduce ground pressure, making it ideal for demanding off-road use. Its articulated chassis, dual hydraulic stabilisers, and pendulum joint ensure stability even when tipping.
THE CAB
The 922HM cab is spacious and ergonomically designed to ensure maximum comfort and efficiency in all conditions. With an air-sprung, ventilated seat and integrated multi-joystick, the operator can easily control the machine and maintain productivity. The cab is equipped with two doors that are illuminated to ensure safe entry and exit. It is ROPS/FOPS certified to meet the highest safety standards and is equipped with heavy-duty viscous suspension that reduces vibration and improves operator comfort.
The instrument display is computerised and provides access to important machine data and reports. An efficient air conditioning system ensures comfortable working conditions, even in hot or cold weather conditions. There are also storage options and connectivity options for 12V/24V sockets. The multi-adjustable steering wheel, armrest and seat allow the driver to customise the cabin to their preferences and needs. Overall, the cab of the 922HM offers the operator the comfort, safety and control needed to handle even the most demanding tasks.
SAFETY
Safety is a crucial factor when it comes to working with heavy machinery like the Hydrema 922HM. That’s why the 922HM is designed with a comprehensive range of safety features to protect both operators and the environment. Among other things, this 20 tonne dump truck is equipped with a tipping alarm that monitors the tipping angle and alerts the operator if there is a risk of unsafe tipping.
To increase safety and give the operator better visibility, the 922HM is equipped with a rear view camera. This allows the operator to see the surroundings behind the machine, which is crucial when manoeuvring and reversing. The camera also fulfils ISO 5006 requirements, which sets standards for visibility from the operator’s position.
Overheating of the brakes can be dangerous and lead to loss of control of the machine. The 922HM has a brake indicator that monitors the brake system and alerts the operator in case of overheating. Hydrema never compromises on safety, and this is clearly reflected in the design of this powerful dump truck.
TIPPING CYCLE
The dump cycle is a key part of a dump truck like the Hydrema 922HM, and it plays a crucial role in the machine’s performance, efficiency and safety. The 922HM has been carefully designed with a focus on optimising the dump cycle to ensure it is performed as quickly, accurately and safely as possible.
The 922HM is equipped with an advanced hydraulic system that contains five separate pumps. This ensures independent operation of the different parts of the machine and an energy-efficient tipping cycle. Two powerful tipping cylinders located under the dump body ensure fast and efficient unloading of materials. The electronic joystick servo control makes tipping smoother with soft start and stop, as well as automatic lift of the skip. This increases the speed and efficiency of the tipping cycle.
To improve tipping safety, a slope indicator in the instrument display alerts the operator if tipping is not safe due to terrain conditions. Overall, the tipping cycle in the 922HM is optimised to ensure fast and safe unloading of materials.
RETARDER SYSTEM
The Hydrema 922HM offers advanced braking technology and improved safety. With an advanced retarder system that utilises 5 hydraulic pumps, this machine achieves maximum braking efficiency with minimal energy loss. The retarder system combines a powerful engine brake and a hydraulic retarder, and is easily operated via a dedicated joystick in the armrest. This increases safety and extends brake life.
In addition, the 922HM has an intelligent brake indicator system that monitors the brakes and warns the driver of potential overheating. This ensures safe and reliable braking performance on any job.
Service
Maintaining your Hydrema 922HM is a simple and efficient process that ensures long-lasting machine performance. With easy access to the engine and filters, thanks to a single button in the cab, daily servicing is quick and convenient.
The large hood opening provides full access to all service points, making it easy to perform daily checks. Automatic central lubrication (optional) ensures proper lubrication with individually adapted quantities for different lubrication points and optimised lubrication intervals.
