Multilift II product line – the perfect electric lifting column for every application

Depending on application, various versions of the lifting column Multilift II are available

Lifting column Multilift II product line

The new lifting column with internal carriage is the ideal solution wherever a vertical adjusting movement is required in combination with a defined installation dimension.

NEW: Multilift II lifting column with internal carriage

The new member of the Multilift II lifting column family is the ideal solution wherever a vertical adjusting movement is required in combination with a defined installation dimension. A distinctive feature of the lifting column is its constant-length design. Thus, the internal carriage of the lifting column is moved and the load guided on the side of the external profile. As a dual-column system, the lifting column with internal carriage, stroke lengths of up to 498 mm (special stroke lengths of 1000 mm max. are possible) and fixing slots in the external profile, is predestined for material lifting mechanisms next to a height-adjustable assembly workstation. When combined with the premium version of the MultiControl II quadro drive controller, all lifting columns can be moved individually, in parallel or synchronously using the controller's drive group management.

Features:

  • Integrated limit switches
  • Self-locking, even under max. load
  • Lateral fixing slot in the external profile
  • Hall sensor for position feedback

Options:

  • Special stroke lengths and installation heights on request
  • Multiple lifting columns can be moved in the BUS system (with synchronous control)
  • Custom solutions on request

Multilift II telescope – unique installation height/stroke ratio

The telescopic version of the Multilift II – the Multilift II telescope – is RK Rose+Krieger's response to greater demands from customers for two-legged bench systems. The three-stage lifting column conforms to the ergonomics standard for workbenches (DIN EN 527-1:2011) and features an optimum height/stroke length ratio: the installation dimension in a retracted position is just 560 mm. The maximum stroke is 650 mm with a maximum lifting force of up to 3000 N per drive. This is currently the only one this type of lifting column on the market. The maximum extension of 1,210 mm conforms to the applicable standards for workplace ergonomics in many applications for assembly workstations, equipment, control rooms, and much more besides. The contact between the profiles – important for stability – has been sized perfectly despite the stroke length and permits high bending moments for both static and dynamic loading.

Multilift II clean – ideally suited to use in the clean room

The Multilift II clean has now been added to the range. It has been deliberately developed for use in the clean room. A special shroud for the DC motor with brushes of the lifting column means discharge of particles is kept to a minimum. To verify its suitability for use in clean rooms, the Fraunhofer Institute for Manufacturing Engineering and Automation IPA carried out a particle emissions test as per DIN EN ISO 14644-1 and certified the lifting column for use in clean rooms up to a globally valid class 4.

Lifting column Multilift II safety – turning things on their head

Multilift II safety is yet another version of the Multilift II lifting column that is in the pipeline. RK Rose+Krieger has developed this column specially for overhead applications in media technology. Its uses include the correct positioning of projectors and monitors, whereby the lifting column is mounted upside down on the ceiling. A proprietary developed internal safety system prevents any accidental extension of the lifting column.

Mulitlift II impact - integrated damping absorbs high impact forces

The Multilift II impact lifting column from RK Rose+Krieger demonstrates perfectly that electrically adjustable lifting columns can not only look good and operate reliably under normal conditions, but can also be extremely robust. The slim electric height adjustment system has an integrated damping system that is able to absorb high impact forces, such as those that occur when unloading a workpiece. This means that the damping system – currently the only one of its kind on the market – prevents any overload due to strong dynamic stresses, making the Multilift II impact particularly suited for the height adjustment of industrial assembly tables.

Lifting column Multilift II ESD – discharging voltages via the lifting column

In the electronics and semiconductor manufacturing industry, electrostatic discharges can impair the function of components being assembled, or even destroy them. Special ESD assembly workstations are equipped with an antistatic finishing that prevents this from occurring. Until now, lifting columns for the height adjustment of workstations have prevented the safe dissipation of electrostatic discharges by interrupting the electric connection between the table and the foot frame. However, with the Multilift II ESD, RK Rose+Krieger has developed a patented electric height adjustment system that is able to dissipate voltages. This has been realised thanks to the design of the outer and inner profiles which are continuously in contact with one another.
