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 dumper 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 hauler.
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.

The 922HM features an articulated chassis with an advanced pendulum rod and dual hydraulic stabilisers in the articulated pivot point. These two stabilisers work together to deliver exceptional stability both when driving and tipping. The chassis construction is made from high-strength steel, ensuring maximum strength while maintaining a low kerb weight. The tilt angle can be adjusted up to +/- 12 degrees, providing versatility and efficiency in any work situation.
The front axle is equipped with electro-hydraulic suspension and individual levelling on each side, which adapts the machine to the optimal position. In addition, the front axle has a standard differential lock with 75% locking action. The rear axle is a heavy-duty bogie axle with reduction gears in the hubs for simple and maintenance-free operation. It also has a large swing angle, which contributes to the machine's agility and performance in different working conditions.
The impressive engine in the 922HM is a Cummins B 6.7 litre 6-cylinder Stage 5 engine. It is equipped with advanced technologies such as DOC, DPF and SCR catalyst with AdBlue addition, ensuring not only compliance with emission standards but also maximum performance. This engine is a 24-valve common-rail turbodiesel with intercooler and electronically variable turbocharger. It delivers a remarkable maximum power output of 231 kW / 314 hp at 2200 rpm and an impressive torque of 1288 Nm at 1500 rpm. A powerful engine ready to tackle any challenge.
The Hydrema 922HM is designed with fuel efficiency in mind. It has an impressive 300 litre diesel tank and a 31 litre AdBlue tank, both integrated into the front chassis. This ensures the machine can work for longer periods of time without interruption, increasing productivity and reducing the need for frequent refuelling.
This 20 tonne dump truck is equipped with a full 2-circuit braking system that includes oil immersed disc brakes on all 6 wheels. This system provides reliable braking power and is maintenance-free, so you can work worry-free. For additional safety, the machine has a Fail Safe handbrake on the front axle. And when it comes to controlling your speed downhill, you have a manually operated retarder at your disposal. The retarder is a smart combination of engine brake and hydraulic retarder that delivers an impressive maximum retarder output of 300 kW / 405 hp. So you can brake safely and effectively in any situation.
The 922HM from Hydrema is equipped with an advanced hydraulic system with no less than 5 hydraulic pumps working in perfect harmony:
