Introduction
The LA44 is available in powerful 10,000 N and 12,000 N versions for use
in various healthcare applications to ensure safe patient handling.
With the LA44 actuator, LINAK offers a product, which with its wide rangeof safety options, low noise level, and outstanding performance is the rightchoice for medical applications such as patient lifts, beds, dental chairs etc.

• Heavy duty actuator• Safety options such as:- Manual lowering: makes it possible to turn the inner tube down by hand, in case of emergency,
or if electrical power is not available.
- Spline: potential work injuries are prevented by the spline, as the actuator can only push and notpull, in case something touches e.g. the lifting boom on a patient lift.
• High side load capacity for high safety: Side load of up to 1000 N is possible without breaking ordamaging the actuator.
• Safety nut: to ensure safe patient handling even when the actuator is no longer new.
• Unique and improved brake to ensure no unintended movement.
