MD Series / Full-electric access
Full
Electric.
Oil-Free.
Meet the MD Series: self-propelled vertical lifts and an order picker built around full-electric, oil-free indoor access.
MD Series
Full-electric indoor access equipment
The MD development path
One series.
More indoor tasks.
MD started with a simple direction: bring full-electric, oil-free access into indoor work. The range now connects vertical maintenance access with a dedicated order-picking format for warehouse teams.
MD570
The first MD vertical lift established the oil-free electric route for higher indoor maintenance access.
MD390-2
The second-generation vertical lift develops the same principle with CAN BUS, proportional control and a compact 6 m working height.
MD390OP
The MD family extends its oil-free electric architecture into order picking, replenishment and everyday warehouse access.
The work behind the choice
A different
way to lift.
Choosing an indoor access platform begins with the work environment. Consider the available width, required height, platform load and how much attention the site can afford to spend on hydraulic oil.
MD570 and MD390-2 use an electric lifting push rod in place of a hydraulic lifting system. Together with the MD390OP oil-free full-electric order picker, the range gives indoor teams access equipment for facilities where cleanup, floor care and reliable day-to-day operation matter.
No hydraulic oil
Remove the oil-related concern from the lifting system and the work area beneath it.
Electric motion
Electric lifting, electric motor drive and model-specific proportional control support controlled indoor access work.
Compact access
An 800 mm machine width helps teams work around aisles, equipment and everyday factory constraints.
Beyond the hydraulic circuit
Beyond oil-free.
A system architecture.
Removing hydraulic oil is only the visible result. The MD Series shows what happens when a conventional lift arrangement is developed into a full-electric, oil-free lifting architecture for practical indoor access work.
Fewer hydraulic
dependencies
Without a conventional lift-system pump, valve, hose and seal arrangement, the lifting architecture has fewer hydraulic elements to manage around the job.
Simpler maintenance
architecture
A more direct electric lifting path can reduce hydraulic-service dependencies and support clearer routine inspection and maintenance planning.
Efficient working
cycle
Electric actuation and energy recovery are intended to make better use of available battery energy. Actual operating time depends on model, duty cycle and site conditions.
Precise motion
and holding
Electric actuation gives the control system a more direct route to manage lifting motion, position and operating status for the task.
Feedback and
diagnostics
A connected control architecture can support condition monitoring, fault diagnosis and more targeted service decisions.
Integration-ready
foundation
Full-electric actuation provides a stronger foundation for electronic controls, data sharing and application-specific automation integration.
Moving from hydraulic power to electric actuation requires the lifting system to account for starting force, scissor geometry, actuator mounting point, minimum scissor angle, stroke, speed, overload protection, holding, synchronization, emergency lowering, cycle life and control integration. Specific component design, data functions and automation capability depend on the confirmed model configuration.
MD vertical-lift engineering
Three systems.
One direction.
The MD570 and MD390-2 vertical lifts are designed around electric power, with no hydraulic oil in the lifting system. MD390OP applies the same oil-free, full-electric product direction in its order-picker format.
Electric
lifting
An electric lifting push rod replaces the conventional hydraulic lift arrangement.
Electric motor
drive
Self-propelled travel supports practical repositioning through indoor work zones.
Model-specific
control
On the MD390-2 vertical lift, proportional joystick control gives operators a direct, measured way to position the platform.
From electric motion to controlled motion
Hardware does
the lift.
Control keeps
work moving.
Electrification is more than removing a hydraulic circuit. The MD390-2 vertical lift brings electric lifting, travel and steering together with control and diagnostic functions that make daily operation easier to understand.
An intelligent actuator can become part of a wider machine or robot data network, reporting data such as actuator position, force, speed, fault code, controller status, cycle count and service condition.
POSITION / FORCE / SPEED / FAULT CODE / STATUS / CYCLE COUNT / SERVICE CONDITIONThese are system-level data possibilities, not a promise that every value, network mapping or automation function is installed on every MD model. Confirm the controller and model configuration before selection.
Where oil-free access matters
Built for the
spaces around
the work.
MD Series equipment is suited to indoor environments where the work area, floor and nearby products need careful protection. The vertical lifts and the MD390OP order picker bring full-electric, oil-free access to clean, controlled operations.
From the MD engineering presentation
See the technology
behind the claim.
These six visuals explain the MD vertical-lift engineering route: no hydraulic oil, electric actuation, energy recovery, independent wheel drive and connected control. The MD390OP order picker is introduced separately below.
No hydraulic oil
Electric lifting removes the hydraulic-oil concern from the lift system and the floor beneath the work.
Recovery on descent
The presentation shows energy recovery while the platform descends, supporting longer operating time between charges.
Independent drive
Independent wheel control and sensors support manoeuvrability and help reduce unnecessary tyre wear.
CAN BUS + diagnosis
Built-in controller monitoring, CAN BUS SAE J1939 communication and command/feedback support connected machine control.
Online and offline diagnosis, command and feedback through CAN BUS or I/O, and a control architecture designed for precise movement.
Energy for the work
Electrification is intended to reduce unnecessary energy demand. Actual performance depends on model, duty cycle and site conditions.
Electric energy recovery during descent helps make more of the available battery energy on a working cycle.
Actuator architecture
The presentation identifies a high-grade electric-cylinder approach for lift and steering. It gives the MD Series a clear electric path from the control command to the lifting and steering movement.
The black actuator reference highlights an integrated controller, absolute position feedback, controlled manual release and a sealed, corrosion-resistant housing. These are reference design directions, not a model-specific promise.
Final component naming, actuator sizing and configuration should follow the approved model BOM. Contact our technical specialists for the detailed selection.

Less hydraulic routine
A cleaner
maintenance path.
The MD vertical-lift materials make one practical point repeatedly: an indoor machine should not create an unnecessary oil-management job around itself.
No lift-system
oil changes
The electric lifting push rod removes hydraulic oil from the lifting system, so there is no corresponding lift-system oil change to plan around.
No hydraulic lift
hoses
With no conventional hydraulic lifting circuit, teams avoid the lift-system hose and leak concerns associated with that arrangement.
Less cleanup
around the job
For indoor operations that care about floors, products or adjacent equipment, an oil-free lifting system makes the operating choice easier to explain.
