4500Nm Planetary Gearbox Winch Drives

    The 4500Nm Planetary Gearbox Winch Drives is a high-torque transmission device designed specifically for heavy-duty winches and lifting equipment. It has a rated output torque of 4500Nm and can withstand a maximum torque of up to 7000Nm. The transmission efficiency is over 95%, making it suitable for continuous heavy-load operation. The output shaft options include solid shaft, or flange interface, allowing flexible connection with hydraulic motors or electric motors. It is widely used in engineering machinery, mining hoists, port winches, and other high-strength working conditions.

    The housing of the 4500Nm planetary gearbox winch drive is made of precision-machined high-strength steel. Its surface is treated with nitriding, providing wear resistance, rust prevention, and corrosion protection. This makes it suitable for harsh conditions such as outdoor use, high humidity, and heavy dust.

High-precision Central Output
The central output uses an internal spline, ensuring stable torque transmission.

Multi-stage Planetary Reduction
The device has a multi-stage planetary reduction system inside, adapting to different loads and speeds.

External Ring Gear Structure
It uses an internal meshing ring gear design to reduce backlash and improve efficiency.

Hydraulic Multi-plate Brake
The built-in hydraulic release brake automatically activates during power loss or emergencies for safety.
