Mounting bracket instructions: Piston rod Application mounting bracket Note the recommended design for the mounting bracket hole. • • • • • LA31 with internal quick release types A and B is not designed for use in pull. The necessary release force on an actuator with 5mm pitch is 75 kg for 6 mm pitch = 50 kg. LA31 with quick release is always with brake (push). The flexible back fixtures (05 or 06) must be standard when the LA31 is equipped with quick release.
Warning • If an LA31 is used in an application where there are repeated dynamic (push/pull) movements in the area 2000 - 4000 N, then it is necessary to contact LINAK A/S in order to make a correct specification of the actuator. Repeated push/pull movements cause extra strain to the actuator and can give safety considerations, the consequence being possible damage to the actuator. • The LA31 actuator must not be exposed to more than 4000 N in pull.
11. LA34 (MEDLINE® CARELINE®) LA34 is a technological state-of-the-art actuator that, due to its innovative construction can push up to 10,000 N at a speed of 5 mm/sec. and with a current consumption of approx. 7 Amp. The strong LA34 actuator is made in a low weight composite material. Its compact design, the outstanding performance and a wide range of safety options makes LA34 the right choice for a variety of medical and industrial applications.
Potentiometer The potentiometer function is mechanically attached to the spindle and registers the number of spindle revolutions. The signal from the potentiometer is measured in Ohm, where the lowest value is measured when the actuator has been run into inward switch stop. The potentiometer is a 10 - turn and therefore it is dependent on the stroke length/spindle pitch. see figure 6.5 Mechanical spline: The splines function so that the actuator can only push, not pull.
12. LA40 (HOMELINE® ) The LA40 is a low noise and powerful actuator which is available in a 1500N, 4000N, 6000N and an 8000N version. Based on the extensive knowledge and experience from previous actuator families, LINAK has developed new gear and braking principles that improve the efficiency of the new LA40. These innovative solutions are covered by several patents.
13. LA40 (MEDLINE® CARELINE® ) The LA40 is a low noise and powerful actuator which is available in a 1,500 N, 4,000 N, 6,000 N and an 8,000 N version.

The LA40 versions are rated up to IPX6 Washable DURATM, except for the LA40 PL version which is rated up to IPX6.
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).

Drawing no.: 0404016-1 15.7 25 20 Quick release mechanism in its nonactivated position. Note that the cable fixture has a maximum travel distance of 20 mm until it hits the housing wall that acts as end stop. The application design must ensure that the quick release cable cannot be pulled the full travel to end stop with excessive pull force.
When the cable is pulled, the quick release is activated with certainty when the cable has less than 12 mm travel distance to give. Drawing no.: 0404016-2 15.7 12 7 At the point when the quick release is activated with certainty, the cable fixture has 7 mm travel left before it hits the end stop. Drawing no.
Make sure that the actuator is unloaded at its fully retracted position! Open the quick release lid using a flat-head screwdriver. Push and tip to release the lock. Run the cable through the slot of the mounting hole for the jacket collar. Pull the cable until the jacket collar is in place. If needed, support the cable jacket by holding it so that it stays in the mounting hole for the jacket collar. Place the cylindrical cable end in the cable fixture. Repeat the procedure if two release cables are used.

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.
