U18C Adjustment Actuator for Solar Tracker Systems
U18C manual adjustment actuator for seasonal solar tracker positioning, with 6,000N push and pull load, 30,000N static load, 2.1mm travel per revolution and IP65 protection for outdoor applications.
U18C Manual Adjustment Actuator for Solar Tracker Systems
Manual Adjustment Actuator for Seasonal Solar Tracker Positioning
The TOMUU U18C is designed for solar tracking systems that require periodic manual angle adjustment rather than continuous daily movement.
It is particularly suitable for solar tracker structures where the north-south angle is adjusted several times during the year to match seasonal changes in solar elevation.
The current configuration provides a rated push and pull load of 6,000N, with maximum static load up to 30,000N when fully retracted.
Key Features
*Maximum static load applies when the actuator is fully retracted.

Designed for Seasonal Solar Tracker Adjustment
Not every solar tracker structure requires continuous motor-driven adjustment. In some PV projects, the tracker angle only needs to be changed several times during the year according to seasonal solar conditions.
The U18C is designed for this type of low-frequency adjustment. Manual operation keeps the drive structure simple while providing sufficient load capacity for periodic tracker angle changes.
Periodic north-south angle adjustment for solar tracker structures where positioning is changed only several times per year.
Suitable for Multi-Point Linkage Structures
For solar tracking systems using mechanical linkage structures, one adjustment mechanism can work with multiple structural points to change the tracker angle.
This approach is especially suitable for projects that prioritize simple mechanical design, low adjustment frequency and convenient long-term maintenance.
Installation & Dimensions
The minimum installation dimension is based on Stroke + 250mm. Both the front and rear mounting ends use Ø14.2mm holes.
Stroke and installation dimensions should be selected according to the tracker structure and the required seasonal adjustment range.
Project Applications
U18 series adjustment actuators are used in solar tracker structures where periodic manual adjustment and mechanical linkage are preferred.
