Lifting columns
Adjustment of workstation systems through to complex mechanical engineering systems
Lifting columns are the ideal drive elements when a motor setting is required in addition to the stable guidance. The whole technology is integrated and not visible from the outside. These lifting columns do not need any additional coverings. Usually, no special electrical knowledge will be required for the commissioning. Various versions are available as standard for the application in the field of medical technology.Several lifting columns can be combined and synchronised and offer further impressive application possibilities. The MultiControl-units can be linked by a BUS-system and enable the synchronization of maximal 32 lifting columns.
Application examples
Multilift (two-stage lifting columns for up to 500 mm travel)
The Multilift is for continuous height adjustment of tables, equipment, assembly workstations and similar applications. The lifting column can be operated alone or as a pair in parallel. To establish a configuration with absolute synchronous run of several drives (maximal 4) a special drive control is available as synchronous version.
| Max. travel. | 498 mm | • Integrated limit switch |
| Max. compressive force. | 3000 N | • Synchronisation via control |
| Max. tensile force. | 1000 N | • Optional manual version |
| Max. travel speed | 8 / 16 mm/s | |
| Protection rating | IP 20 |
Multilift II (two-stage lifting columns for up to 500 mm travel)
Customer feedback formed the basis for a number of improvements in the design of the Multilift II. One new feature is an assembly slot on both sides of the external profile of the electric lifting column, which is compatible with the RK Rose+Krieger aluminium profile system and can take corresponding slot stones. They allow additional attachments like reinforcements, screening and so on to be mounted without any problems.
| Max. travel. | 497 mm | • Synchronous package |
| Max. compressive force. | 3000 N | • Plug & Work (factory-initialised) |
| Max. tensile force. | 3000 N | • Lateral fixing slot in external profile |
| Max. travel speed | 8 / 16 mm/s | |
| Protection rating | IP 30 |
Multilift II (multi-stage lifting columns for over 500 mm travel)
The telescopic version of the Multilift – the Multilift II telescope – is RK Rose+Krieger's response to greater demands from customers for two-legged bench systems. The new lifting column conforms to the ergonomics standard for workbenches (DIN EN 527-1:2011) and features an optimum height/stroke length ratio: With an installation dimension of 560 mm and a stroke length of 650 mm, the Multilift II telescope also handles compressive forces of up to 3,000 N. This is unique in the market for a lifting column of its form at present.
The Version Multilift II -telescope- is available from the 2nd quarter of 2015.
| Max. travel. | 650 mm | • Synchronous package |
| Max. compressive force. | 3000 N | • Plug & work (factory-initialised) |
| Max. tensile force. | 2000 N | • Lateral fixing slot in external profile |
| Max. travel speed | 8 / 16 mm/s | |
| Protection rating | IP 30 |
RK Slimlift (two-stage lifting columns for up to 500 mm travel)
The RKSlimlift looks unflashy and filigree but it is highly loadable. The whole drive unit is placed in the column and is not visible from the outside. Fixing slots in the side walls offer the possibility to attach additional components, e.g. panels, cable channels and braces.| Max. travel. | 500 mm | • Integrated limit switch |
| Max. compressive force. | 4000 N | • Synchronisation via control |
| Max. tensile force. | 2000 N | • Optional manual version |
| Max. travel speed. | 8-32 mm/s | |
| Protection rating | IP 30 |
RK Powerlift (two-stage lifting columns for up to 500 mm travel)
The RK Powerlift has been developed to be used as single column. Its high stability allows amazing side forces at high travel speeds. The modern and timeless profile design does not need any coverings.
| Max. travel | 500 mm | • Integrated limit switch |
| Max. compressive force | 3000 N | • Synchronisation via control |
| Max. tensile force | 3000 N | • Integrated control |
| Max. travel speed | 10-50 mm/s | • Optional manual version |
| Protection rating | IP 30 |
RK Powerlift telescope (multi-stage lifting columns for over 500 mm travel)
| Max. travel | 650 mm | • Integrated limit switch |
| Max. compressive force | 1600 N | • Synchronisation via control |
| Max. tensile force | 800 N | • Choice of internal or external control |
| Max. travel speed | 15-30 mm/s | |
| Protection rating | IP 30 |
Alpha Colonne (multi-stage lifting columns for over 500 mm travel)
The guide profiles of the Alpha Colonne are exactly square shaped. This makes the side forces identical for all sides. Compared to other systems, it has a third guide step with a large overlapping when it is extended which improves its stability.
| Max. travel | 700 mm | • Integrated limit switch |
| Max. compressive force | 3000 N | • Synchronisation via control |
| Max. compressive force | 3000 N | • Integrated control |
| Max. travel speed | 8-18 mm/s | |
| Protection rating | IP 30 |
Lambda Colonne (multi-stage lifting columns for over 500 mm travel)
The lifting column LAMBDA-Colonne is a telescopic drive which is alone or as a pair (Twin) suitable for lifting and lowering in many possible applications. It can be used for lifting forces of maximal 4,500 N (single) and 9,000 N(Twin) and a total lifting height of 600 mm.
| Max. travel | 600 mm | • Integrated limit switch |
| Max. compressive force | 4500 N | • Synchronisation via control |
| Max. tensile force | 4500 N | |
| Max. travel speed | 8-20 mm/s | |
| Protection rating | IP 54 | IP 40 |
