EXPLANATION
How HUBBERT Works
The System in One Sentence
Electrically Adjustable and Self-Leveling
Stepper motors move the lift bed in a controlled way via trapezoidal spindles. This allows the bed to travel precisely to defined heights and compensate for vehicle tilt by leveling the bed.
Stable Guidance
Four guide rods are permanently installed. Two crossbars support the bed surface and form the stable bed support.
Individually Adaptable
Size and installation position are configured to suit the vehicle, interior height, bed position and conversion concept.
The Technical Principle
How HUBBERT works: The electric lift bed combines guided mechanics, stepper motors, trapezoidal spindles and automatic leveling into a flexible system for camper conversions.
- four guide rods for guided lifting movement
two crossbars as the load-bearing support
flexible positioning in the vehicle
suitable for panel vans, cabins and special bodies
Drive and Control
Stepper Motors and Trapezoidal Spindles
The lifting movement is driven by stepper motors and trapezoidal spindles. The motors allow precise control and the system runs fully synchronized. The self-locking trapezoidal spindles transfer the force mechanically and reliably.
- controlled height adjustment
- precise movement through defined motor positions
- mechanical power transmission via self-locking trapezoidal spindles
- fully synchronized movement of all lifting points
- controlled height adjustment
- precise movement through defined motor positions
- mechanical power transmission via self-locking trapezoidal spindles
- fully synchronized movement of all lifting points
Control Board
The control system runs via a circuit board and can optionally be supplied plug and play with a preconfigured cable set. Operation takes place via a modern touch display. The board connects motors, limit switches and controls. Optical limit switches allow the system to recognize safe reference points.
- optical limit switches
- home position as reference
- adjustable heights
- operation via modern touch display
- simple operating logic
- optical limit switches
- home position as reference
- adjustable heights
- operation via modern touch display
- simple operating logic
Comfort Functions in the Touch Display
The modern touch display gives clear access to saved heights, leveling and other comfort functions. This keeps the system easy and safe to use in everyday life.
Dark Mode
Comfortable operation in low light, for example in the evening or at night in the vehicle.
PIN Assignment
Limit switches, motors, voltage, temperature and leveling sensor can be checked.
PIN Assignment
Protection against unintended operation and clear release of the control system.
Languages
The user interface can be used in several languages.
Collision Control
Collision control helps ensure safe operation of the lift bed.
Self-Diagnosis
Checks for limit switches, motors, voltage, temperature and leveling sensor.
Four Programmable Heights
HUBBERT can store four heights with centimetre precision. Typical everyday positions can be reached directly, such as sleeping position, sitting position, storage position or travel position.
Sleeping
HUBBERT first moves to the selected height and then levels the bed in that position if required. This means the system does not level in a general position first, but exactly where the bed will be used.
Sitting
More headroom below the bed and better use of open space concepts.
Storage
The bed can be positioned to create space underneath for luggage, bicycles, motorbikes or conversion components.
Leveling: Sleep Level on an Uneven Pitch
During leveling, HUBBERT can compensate for different heights. The bed first moves to the desired sleeping or use position and then levels itself, even when the vehicle is not perfectly even.
It is important that the bed is not tensioned during leveling. Thanks to the structural degrees of freedom, the system cannot jam while leveling. That is why length compensation is built into the design.
How Length Compensation Works
In one direction, the crossbars provide the compensation: two square tubes slide into each other. In the other direction, the bed can move on the crossbars through cut-outs in the bed frame.
- length compensation via square tubes sliding into each other
- additional compensation via cut-outs in the bed frame
- the system can level without tensioning or jamming
Mounting and Installation
Installation is not limited to one fixed standard position. HUBBERT mounting points are configured to suit the vehicle, planned bed size and desired installation position.
- flexible size
- flexible installation position
- suitable for longitudinal or transverse beds
- installation possible in panel vans, living cabins and special bodies

Stable in Every Height
HUBBERT is not only stable in the upper or lower end position. Thanks to the guide rods, crossbars, fully synchronized movement and self-locking trapezoidal spindles, the bed remains load-bearing and controlled even at intermediate heights.
Guided Movement
Four guide points stabilize the lifting movement.
Mechanical Support
The bed surface rests on two crossbars.
Controlled Position
Home position, limit switches and saved heights ensure reproducible positions.
Fail-Safe Operation and Service-Friendly Design
Diagnostic functions help with troubleshooting: limit switch states can be checked, undervoltage is indicated by LED, and short circuits at external connections are shown on the board via LED.
Emergency Operation via Battery Pack
In an emergency, the control system can be powered by a simple battery pack with adapter.
Modular Board
Drivers and Teensy can be replaced easily if required.
Robust Motors
NEMA 23 motors in industrial quality provide robust and reliable movement.
Manual Emergency Movement
The trapezoidal spindles can be turned by hand in an emergency.
Technical Data and Individual Consultation
Technical data is available for all HUBBERT models. During the consultation, we check together whether the dimensions fit your vehicle and conversion, or whether a special solution makes sense.
You do not have to define the right technical solution alone. We look together at vehicle model, interior height, bed position, motor position, accessories and possible special cases.
Of course, individual consultation and individual manufacturing are included in the price at no extra charge.
