Recommendations • Patient lift and stand aids: - Long installation dimension: must always be used for patient lifts. - Do not hold the inner or outer tube while the actuator is running. There can be a risk of squeezing between the manual lowering unit and the outer tube. - Always use the ratchet spline functions for patient lifts.
Spline: • Required minimum push load 200 N on the actuator to allow inward movement (otherwise the spline can be activated) (picture 1). • Required activation pull force during inward operation: <100 N to activate the ratchet spline to avoid squeezing situations (picture 2). • For QR versions: Force required to manually activating spline (actuator not in operation): Static pull force = 300 - 550 N. For manual pull out (extend) of the inner tube (picture 3).

4. Information on specific columns 1. BL1 (MEDLINE® CARELINE® TECHLINE®) The BL1 is a 3-part lifting column designed to be used for example in hospital beds, nursing home beds, treatment chairs, couches and dental chairs. The lifting column is compact and has a long stroke length. The 3-part guidance enables an overlap between the individual profiles, which ensures a high degree of stability. The lifting column has an open spindle actuator with a chain drive inside which is practically noiseless.
Recommendations • • • • Please follow the important BL1 mounting guidelines. Max. storage temperatures: +50 °C. BL1 is for use in push applications, cable outlet from smallest profile (top) or biggest profile (bottom). See top and bottom plate dimensions. When washing according to IPX6 parameters, it is not allowed to splash water directly onto the plastic frames between the profiles. Direct splashing is only permitted on the aluminium profiles.

2. LC3 (MEDLINE® CARELINE® ) The LC3 2-stage and 3-stage set the standard for vertical lifting columns to high-end medical applications. This compact lifting column fulfils the market requirements for a solid and stable lifting column. Usage: • Duty cycle: 10%, 2 minutes continuous use followed by 18 minutes not in use • Operation temperature: +5 °C to + 40 °C • Storage temperature: -40 °C to + 70 °C • Compatibility: Compatible with LINAK control boxes. Please contact LINAK.
LC3 mounting guidelines If you want to use the column with a high off-center load, we recommend that you install the weight in one of the 3 ways illustrated by the green symbols. It is not recommended to install the weight on the opposite side of the mechanical endstop as illustrated with the red symbol. This installation can create an uneven movement when the lifting column reaches the endstop position. Mechanical endstop Use 4 pcs. M10 8.8 screws, in each end, for mounting to the application.
