HTL4 Telescopic Linear Actuator

  • Three-stage telescopic design
  • For cameras, LiDAR and robot sensor modules
  • Compact retracted height: stroke / 3 + 200 mm

The HTL4 is a three-stage telescopic linear actuator developed for elevating cameras, LiDAR, antennas and other sensor modules on mobile robotic platforms. Its compact retracted form helps inspection robots move through restricted spaces, while the extended mast raises the sensing position to improve visibility and measurement coverage.

Typical applications

  • Quadruped and wheeled inspection robots
  • Mobile camera and LiDAR elevation systems
  • Temporary antenna or communication-module positioning
  • Autonomous platforms requiring a compact retractable sensor mast

Mobile robot sensor-mast application

Mounted vertically on an inspection robot, HTL4 can retract the sensing module for transport and obstacle clearance, then extend it at the inspection point to obtain a higher viewing or scanning position. The robot structure should guide and support external side loads; the actuator should be selected according to the payload, stroke, extension speed and operating environment.

Configuration support

For selection support, please provide the sensor payload, required stroke, target speed, voltage, duty cycle, installation space, control or feedback requirement and operating environment. View more electric linear actuators or contact GEMING for an OEM configuration review.

Time-Proven Application

Installed in a woodworking saw table in 2017,
this linear actuator remained in continuous service for years without replacement.

In 2025, the same customer reordered the identical model for a new project.
