U18C Manual Linear Actuator for Solar Tracker Mount Adjustment
Manual Mechanical Adjustment for Outdoor Solar Tracker Mounts
The TOMUU U18C is a manual linear actuator designed for solar tracker mount structures that require periodic mechanical angle adjustment without continuous motor-driven movement.
It can be integrated into different solar tracker mounting structures, with the actuator stroke and installation dimensions selected according to the required adjustment range and mechanical layout.
The current configuration provides a rated push and pull load of 6,000N, with maximum static load up to 30,000N when fully retracted.

Manual Mechanical Adjustment for Solar Tracker Mounts
In some solar tracker structures, the mounting angle does not need continuous movement throughout the day. A manual mechanical adjuster can be used where the tracker position is changed periodically according to project operation or seasonal requirements.
The U18C converts manual rotary input into linear movement, allowing the mounting structure to be repositioned through a simple mechanical adjustment method.
Application Focus:
Manual mechanical positioning for solar tracker mount structures where adjustment is required periodically rather than continuously.
Installation & Dimensions
The required stroke depends on the tracker mount geometry and the target adjustment range. The minimum installation dimension is based on Stroke + 250mm ±3mm.
The front and rear mounting ends use Ø14.2mm holes. Stroke and installation dimensions should therefore be confirmed together with the tracker structure during product selection.
Solar Tracker Mount Applications
U18 series manual adjustment actuators can be integrated into different solar tracker mount structures for periodic positioning. The actual actuator stroke and installation dimensions are selected according to the mechanical layout and required angle range.
