K Series 3-In-1 Electric Motor Gear Reducer For Crane
The K series three-in-one electric motor gear reducer for crane is a power transmission solution specially designed for crane machine and other industrial equipment.
- Power Range:0.18~160 ton
- Torque Range:200-40,000 Nm
Product Description:
The K Series Three-in-One Electric Motor Gear Reducer is a highly efficient transmission device that integrates a gear reducer, electric motor, and brake (or other drive accessories) into a single unit. It features a helical-bevel gear transmission structure, offering notable advantages such as high transmission efficiency, high torque output, and a compact design. This series of products, designed with a modular approach, supports various installation configurations (horizontal, vertical, flange-mounted, etc.), making it suitable for applications in industrial automation scenarios where space utilization and transmission performance are critical requirements.
Features:
-
01
Speed Reduction and Torque Increase
By combining multiple gear stages, the output speed is reduced while increasing the output torque, meeting the requirements for heavy-duty starting and continuous operation.
-
02
Energy-Efficient and High-Performance
Optimized gear meshing design improves transmission efficiency and reduces energy consumption.
-
03
Compact integration
A three-in-one design reduces installation space, simplifies wiring, and eases maintenance.
-
04
Modular configuration
Auxiliary equipment such as brakes, encoders, and variable frequency drives can be selected according to different operating conditions to meet customized requirements.
Application:
The K series three-in-one electric motor gear reducer is commonly used in overhead cranes, gantry cranes, and other lifting equipment, and is widely used in metallurgical mines, ports and terminals, metallurgy, machinery manufacturing, and other fields. It is particularly suitable for industrial applications with high requirements for transmission stability, reliability, and space compactness.
