Clutches/torque limiters are available on most of Power Jacks linear actuators whether as a standard option or a custom design.

The EMA-Series linear actuator have a standard friction clutch option. The friction clutch in these actuators is set to slip when the rated load limit of the actuator is exceeded. This is to prevent damage to the actuator due to jamming or over-heating resulting from an excessive load. The load will be held securely should the clutch slip. The clutch also allows end of travel protection, but is not designed to be slipped repeatedly. Select an linear actuator with internal limit switches or install external limit switches. Severe over-loading will cause the actuator clutch to slip and allow the load to self-lower.

Rolaram linear actuators can have a clutch or torque limiter fitted on request. These clutches can be specified to meet any requirement e.g. ratcheting auto re-engagement, overload manual re-engagement, integrated limit switch, etc.
