Heavy-Duty Manual Adjustment for Solar Trackers
Solar tracker structures may require manual mechanical adjustment at different stages of installation, positioning or operation. For applications requiring higher mechanical load capacity, the U18 provides 12,000N push and pull load while maintaining a simple motor-free structure.
The 4mm/r adjustment speed allows controlled mechanical positioning, while the actuator structure can be configured according to the required stroke and installation arrangement.
Designed for solar tracker applications requiring higher push and pull load capacity from a manual mechanical actuator.
Load Capability for Solar Tracker Structures
The actuator is rated for 12,000N push and pull load with a maximum load of 20,000N. Maximum static load can reach 50,000N under the 500mm-stroke condition specified for the product.
Actual actuator selection should consider not only load, but also stroke, installation dimensions, tracker geometry and the mechanical linkage arrangement.
U18 Specifications & Dimensions
The minimum installation dimension is based on Stroke + 250mm ±2mm, with a Ø25mm front mounting hole.
Please confirm the required stroke and mechanical interface before final product selection.

Solar Tracker Applications
U18 series manual actuators are designed for mechanical adjustment in outdoor solar tracker structures. Configuration should be selected according to the tracker design, required load, stroke and installation arrangement.
