The HTA3 / HTD3 Robot Lifting Column series is designed for embodied intelligence robots, mobile robots, service robots, AGV/AMR intelligent equipment, and human-machine collaborative robotic systems. The series integrates precise vertical lifting, stable load support, and intelligent height adjustment for robot walking, obstacle avoidance, workstation docking, and automated operation scenarios.
Both models use high-strength formed aluminum alloy profiles with an internal quiet servo lifting system. They support smooth start and stop, low-noise operation, accurate stroke control, and communication with robot control systems for automatic height matching, fixed-point lifting, and linked start/stop.

For robot lifting applications, final selection should consider payload, eccentric load, stroke, installation height, robot interface, communication protocol, wiring method, duty cycle, and operating environment.
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.
