- Description
ATV Utility Winch EWT3500A with Steel Gears and Separate Controls
The EWT3500A is an electric ATV utility winch rated at 3,500 lb (1,588 kg) on the first rope layer. It combines a permanent magnet motor, a three-stage planetary steel gear reducer and automatic screw-cone braking. The separate control box is a listed part of the supply arrangement and should be considered alongside the winch body when planning the installation.
- First-layer rated pull: 3,500 lb (1,588 kg).
- Transmission: Three-stage planetary steel gear reducer with a 166:1 reduction ratio.
- Mounting interface: Listed 79.5 mm spacing with two M8 positions.
The intended pulling task, vehicle electrical supply and mounting structure determine suitability. The 3,500 lb rating is not a universal vehicle weight limit or a guarantee of fitment.
Separate Control Box and Operator Controls
The original feature list states that each winch comes with a separate control box. It also describes direct high-current switch control, control-box switch operation and an ATV handlebar switch. The order specification should identify which operating arrangement is supplied with the selected version.
- Control-box position: Identify the proposed mounting location and available space.
- Operator interface: Confirm the required switch type and operating position.
- Electrical documentation: Request the wiring diagram and connection requirements for the supplied configuration.
The control options should not be interpreted as multiple complete circuits supplied simultaneously. Irun Winch should confirm the included controls, cables and connection components in the quotation.
Steel Planetary Reducer and Automatic Brake
Three-Stage Steel Gear Reduction
The EWT3500 feature list identifies a three-stage planetary steel gear reducer. The listed 166:1 ratio provides a specific transmission reference for model comparison without relying on unsupported efficiency claims.
- Gear specification: Confirm the reducer configuration in the technical documents.
- Maintenance information: Request lubrication and service requirements.
- Performance review: Compare the voltage-specific speed and current values at the required pull.
The supplied description does not specify a steel grade, measured transmission efficiency or continuous-duty rating. These details should not be inferred from the gear material alone.
Patented Clutch Structure and Screw-Cone Braking
A patented clutch structure, free-spooling clutch and automatic screw-cone braking are listed features. Their operating procedures and maintenance requirements should be reviewed before use.
- Clutch access: Keep the mechanism accessible after installation.
- Operating procedure: Confirm engagement restrictions and permitted recovery methods.
- Brake inspection: Follow the model-specific maintenance instructions.
The description identifies the clutch structure as patented; it does not establish that the gear reducer itself is patented. Lifting approval is not provided by the supplied data.

Compare Voltage Versions at the Intended Load
Both versions list a no-load speed of 4.4 m/min. At 2,500 lb, the listed 24V speed is higher, while at 3,500 lb the table lists 1.8 m/min for 12V and 1.5 m/min for 24V. The complete operating points should therefore be reviewed rather than assuming one voltage is faster at every load.
- 12V rated-pull point: Listed at 1.8 m/min and 170 A.
- 24V rated-pull point: Listed at 1.5 m/min and 100 A.
- Installation review: Confirm supply, cabling, connection and protection requirements.
The listed performance points do not replace the electrical installation instructions. Request permitted operating duration and cooling requirements separately.
Review the Working Rope Layer
The listed pulling capacity decreases from 3,500 lb on the first layer to 2,214 lb on the fourth. Cumulative rope storage reaches 13.4 m on the fourth layer.
The original fifth-layer entry has no pull or storage values. It is retained as supplied and must not be interpreted as zero capacity or an additional approved rope allowance.
