Hydraulically actuated quick change systemCab tilt system
Cab tilt systems are used to tilt the truck cab to allow access to the engine compartment during servicing. Tilting can be done by means of a manual or electro-hydraulic pump. The cabin is locked using special cab locks. The complete cab tilting system is designed according to customer-specific requirements and meets the highest demands.

- Convenient access to the engine compartment
- Cab tilt cylinder with patented lost motion system for optimum comfort while driving
- All system components from a single source and individually adapted to the available installation space

- Optionally available as shuttle: a unit consisting of a cylinder with a bi-directional pump and its own oil tank only needs to be electrically connected. There is no need to install hydraulic lines and installation space is saved
- Weight-optimised solutions can be adapted to customer-specific requirements
Hydropneumatic cabin suspension
The hydropneumatic suspension is based on specially developed suspension cylinders, pressure accumulators and a preset damping valve.
The advantages at a glance
- Highly improved driving performance and increased efficiency
- Significant gain in comfort and fatigue-free working
- Manual adaption of the suspension and damping behaviour or automatically regulated adaption to the driving situation
- Improved driving safety due to adapted vehicle behaviour for example during braking processes or driving along curves
- Reduction of straining vibrations
- Spring assemblies, air springs, shock absorbers or stabilizer rods are unnecessary
- Linking of sensors for anticipatory systems (e. g. information from external speed sensors can be included in the suspension algorithm and the hydropneumatic suspension can automatically adjust itself to different driving situations)
System components
- Suspension cylinders
- Levelling Sensor
- Manifold
- ECU (Controller)
System options
- Passive, adaptive or semiactive system according to customer requirements
- Height control
- Transverse levelling
- Roll stabilization
- LS levelling valve can be designed as stand-alone or as valve pallet for blocking
- By connecting the system to the vehicle control system and feeding in further signals, it is possible to optimise system performance in terms of a faster response to pitching movements during load changes and braking
Different system designs
Angle sensors, controllers and a manifold for pressure regulation allow different designs of the system depending on the setting and version:
- as passive hydropneumatic suspension with preset damping,
- as adaptive hydropneumatic suspension with driver-adjustable damping,
- or as semi-active hydropneumatic suspension with active damping.
The passive suspension system is predestined for constant ambient conditions, e. g. with constant loads. The semi-active and adaptive counterparts, on the other hand, are particularly suitable for use in different driving situations or with changing loads – for example, for driving on the road and on rough terrain.
WEBER-HYDRAULIK suspension solutions are always developed and adapted individually with the customer to achieve optimum results.
Hydropneumatic axle suspension
WEBER-HYDRAULIK hydropneumatic axle suspension systems improve driving comfort and safety in a wide range of applications, e. g. in trucks and trailers, agricultural vehicles, construction machinery and other mobile machinery.
The hydropneumatic suspension is based on specially developed suspension cylinders, pressure accumulators and a fixed damping valve.
The advantages at a glance:
- Integration of suspension and damping functions in one system
- Supreme drivability and comfort
- Delivered pre-assembled
- Highest quality standard
- Broad range of applications
- Prevention of pitching on braking
- Frictionless compact seals
- Roll stabilization optimizes handling in curves
System components
- Suspension cylinders
- Sensor
- Manifold
- ECU (Controller)
System options
- Levelling function
- Roll stabilization
- Adaptive damping
- Integrated position measurement system
- Axle lift during empty runs to avoid unnecessary friction or to improve traction
- Wheel lift e. g. for changing tyres
- Manual switch-off of the suspension for blocking individual axles in certain situations (e. g. last axle for dump trucks or front axle for wheel loaders/tractors for loading operations)
- Special self-developed design of the suspension cylinders for particularly short construction with maximum spring deflection
- One or two friction-optimised suspension cylinders per wheel depending on the installation space available
Different system designs
Angle sensors, controllers and a manifold for pressure regulation allow different designs of the system depending on the setting and version:
- as passive hydropneumatic suspension with preset damping,
- as adaptive hydropneumatic suspension with driver-adjustable damping,
- or as semi-active hydropneumatic suspension with active damping.
The passive suspension system is predestined for constant ambient conditions, e. g. with constant loads. The semi-active and adaptive counterparts, on the other hand, are particularly suitable for use in different driving situations or with changing loads – for example, for driving on the road and on rough terrain. Semi-active axle suspension also leads to a more balanced load distribution and thus reduces the impact on the ground. In the rough terrain, it is also possible to increase the axle load on the powered axles in order to achieve better traction. A sensor attached to the chassis continuously records the driving situation and driving conditions and sends the collected data to the Electronic Control Unit (ECU) of the suspension system. This in turn is connected to the vehicle’s ECU, which allows the driver to change the damping settings as required. In the case of dumpers, for example, the rear axle can be locked if necessary so that the vehicle remains stable when the trough is tilted. In addition, a lateral slope compensation can be carried out for this application, if necessary, to prevent the dumper from tipping over to the side when emptying.
WEBER-HYDRAULIK suspension solutions are always developed and adapted individually with the customer to achieve optimum results.
Electrohydraulic steering systems
Electrohydraulic steering systems for steered axles on trucks and trailers, agricultural and forestry machinery, industrial trucks and hybrid vehicles ensure higher driving comfort and greater manoeuvrability.
Different versions of the steering system, adapted to the special application situation at the customer’s site, offer maximum steering comfort in all situations. Up to three steered axles can be equipped with the steering systems of WEBER-HYDRAULIK and also steering systems for very heavy loads, as is the case with construction vehicles, can be realized individually with the customer.
