Rely on your actuator

Self-lock
To avoid actuator drifting, and potentially creating dangerous situations, LINAK actuators come with a self-lock function. The minimum self-lock always equals the max thrust lifting performance. LINAK works with three types of lock functions. One relies on the spindle pitch, another is a magnetic motor brake, while the third has a mechanical brake.

Mechanical endstop
This is an extra safety feature, making the actuator first-failure-safe. If the electrical endstop switch should ever fail, a small disk at the endstop takes over and curls around the spindle. This effectively stops all movement when the mechanical endstop is reached. 

Safety nut
A safety nut acts as a fail-safe against potential failure of the main nut. The safety nut is an extra nut moving with the main nut inside the actuator. If the main nut should break, the safety nut will immediately carry the full load and thereby prevent potential harmful failure. Practically, the safety nut will allow you to lower/retract the actuator slowly to a safe position and call for service.

Spline
LINAK offers three different types of spline: mechanical, electrical and ratchet spline. All three spline types prevent accidental squeezing of limbs between moving parts in an application, for instance, in a bed frame or in a couch/table when the actuator retracts. Also, LINAK spline will immediately stop lowering the backrest, e.g., in a hospital bed if obstructed, thus preventing the application from being damaged.

Quick release
Quick Release is important functionality that ensures fast lowering of the application in emergency situations. When used in beds, it allows caregivers to quickly lower the backrest to a horizontal position in case the patient needs CPR. 

Manual lowering
Products used in hoists are constructed for easy OEM application compliance with the standard ISO 10535. Manual lowering is a standard safety feature for lifting actuators in hoists and is used in emergency situations in case a power cut occurs.
