VH9 Dimensions & Performance Drawing
Official dimensional drawing for model VH9-61S130-RC-2415300 Rev.A — mounting interfaces, motor data, hard limits and wiring.
Product Overview
Larger Vertical Drive for Single-Axis Solar Tracking
VH9 steps up from VH7 for longer tracker rows and higher holding demand, while keeping the same vertical solar-tracker mounting style.

with a 61:1 worm-gear ratio, ±60° hard limit and ≤0.2° precision.
A 24VDC IP65 planetary reducer motor and 1 m cable simplify field wiring for solar EPC and OEM tracker builders.
Slotted base feet, 8×M16 side mounting on a 130×130 mm pattern and a square output interface support repeatable installation on torque-tube tracker structures.
Product Highlights
- 9-inch vertical slewing drive for solar trackers.
- Rated output torque 6405 N·m / holding torque 56 kN·m.
- Hard travel limit ±60° for tracker safety.
- Gear ratio 61:1 with precision ≤ 0.2°.
- Standard 24VDC IP65 motor; 36V / 48V / AC options available.
- Static axial rating 338 kN for heavier tracker structures.
Technology
What Is a Slewing Drive?
A compact rotary gearbox built around a slewing bearing for high integration, large reduction ratio and easier field use.
A slewing drive is a specialized reduction product derived from the slewing bearing. It integrates the bearing, gearing, seals, housing and drive interface into one assembly,
so the unit can carry radial and axial loads while transmitting torque for rotation. Because the slewing ring’s inner and outer races form the structural base and the rotating path,
the drive can provide continuous 360° motion and accept a power source mounted on the same frame—often called a rotary reducer, turntable reducer or drive turntable.
By transmission type, slewing drives are commonly gear-driven or worm-gear driven; by enclosure they may be open or closed.
Open gear turntables are familiar on excavators and tower cranes as the final stage of a reduction chain, usually paired with a planetary reducer upstream.
Integrated worm-gear slewing drives—especially enveloping-worm designs—raise torque capacity and positioning accuracy, and are well suited to digital control on solar and wind tracking,
as well as robots, radar, heavy lifting and precision CNC turntables.
Rotation may be on a single axis or coordinated across multiple axes. Elerover’s VH9 is a closed worm-gear vertical slewing drive for single-axis solar tracker systems.
The standard drawing package uses a 24VDC IP65 planetary reducer motor; VH9 can also be configured with 36V, 48V or AC motors to match site power and controller design.

FAQ
Is VH9 the same as SVH9?
No. VH9 is a vertical single-axis slewing drive for solar trackers. SVH9 is a dual-axis drive for azimuth and elevation control. Choose based on your tracker architecture.
How does VH9 compare with VH7?
VH9 offers higher output and holding torque (6405 N·m / 56 kN·m) and a larger 130 mm side mounting pattern for heavier single-axis tracker rows. Share your load case and we will confirm the best size.
Can VH9 be used on utility-scale solar trackers?
Yes. 6405 N·m output torque, 56 kN·m holding torque, IP65/C3 protection and ±60° hard limits suit many horizontal single-axis PV tracker designs — confirm wind load and row length first.
What motor voltages are available on VH9?
The standard drawing package uses a 24VDC IP65 planetary reducer motor. For single-axis solar tracker projects, VH9 can also be configured with 36V, 48V or AC motors—confirm controller and site power first.
Can mounting and cables be customized?
Yes. Base feet, side mounting, cable length and motor packages can be reviewed for OEM tracker programs.
