PLC-Integrated Servo Winch for Industrial Use

LYFOOCRANE Automation-Ready Lifting Systems

PLC-Integrated Servo Winch for Industrial Machine Builders

A configurable motion-control winch for OEM equipment, automated production lines and space-constrained installations. Servo drive technology, programmable controls and a shaft-connected drum layout give engineers greater freedom to coordinate lifting or pulling with the rest of the machine.

A Winch Designed as Part of the Machine

This system is intended for projects where a winch must communicate with other equipment rather than operate as an isolated device. The servo drive manages programmed motion, while the PLC exchanges commands, status signals and interlocks with the host machine. A separate drive shaft between the gearbox and drum allows the drive package and rope-handling section to be positioned around structural or space limitations.

Programmable Motion

Configure speed, acceleration, deceleration, travel and operating sequences around the process.

PLC Connectivity

Exchange machine commands, ready states, faults, limits and interlock signals.

Flexible Equipment Layout

A shaft-driven drum can be located away from the motor and gearbox when the installation demands it.

Managed Rope Winding

Dual grooved drums support a more orderly rope path across the selected travel.

Industrial Integration Architecture

Motion Layer

Servo Motor and Drive

Provides adjustable motor speed and responsive torque control for the approved motion profile.

Control Layer

PLC and Machine I/O

Coordinates the winch with sensors, process equipment, operator controls and safety functions.

Transmission Layer

Hardened-Gear Reducer

Converts motor output into usable drum torque for the selected load and speed.

Mechanical Layer

Remote Shaft and Drum

Separates the rope-handling location from the main drive package to suit complex machine layouts.

Travel Layer

Adjustable Limit Points

A four-point limit arrangement provides configurable travel references and over-travel inputs.

Operator Layer

Local or Centralized Control

Use a pendant, customer HMI, remote commands or the main equipment control system.

General Technical Range

Design Item Available Configuration
Nominal Capacity Range 250 to 8,000 kg; final rating determined by application review
Power Supply 220–380 V AC with single-phase or three-phase versions
Primary Drive Servo motor and programmable drive
Gear Reduction K-series hardened-gear reducer or project-specific equivalent
Drum Configuration Dual grooved drums for managed rope winding
Drive-Shaft Layout Custom shaft length and support arrangement for separated drive and drum locations
Travel Limiting Four-point adjustable limit-switch arrangement
Control Methods Pendant station, remote commands, HMI or PLC integration
Base Enclosure Protection IP55; higher environmental protection available when specified
Project Variables Rope speed, rope length and diameter, feedback devices, PLC logic, mounting and shaft geometry

Positioning performance is application-dependent. Accuracy must be confirmed from the selected feedback device, rope-layer geometry, load behavior, mechanical compliance and control architecture.

600 kg Reference Configuration

The values below describe one example unit. Other capacities require separate drive, drum, rope and structural verification.

Command SignalsEnable, direction, speed reference, move command, stop and reset.
Status FeedbackReady, running, stopped, limit state, drive alarm and system fault.
Process InterlocksCoordinate the winch with guards, fixtures, sensors and upstream equipment.
Motion ProfilesDefine acceleration, working speed, approach speed and controlled stopping behavior.
Feedback OptionsSelect suitable motor, shaft, drum or external position feedback for the required task.
Operator InterfaceIntegrate local pendant controls, an HMI or supervisory commands from the machine PLC.

Safety Must Be Engineered at System Level

Limit switches are part of the motion-control architecture but should not be treated as the complete safety system. The machine builder remains responsible for the risk assessment and for specifying suitable brakes, overload protection, emergency stopping, guarding, safe control functions and structural load paths for the final installation.

Information Needed for Engineering

✓  Environmental and safety requirements

System Integrator FAQ

Can the winch connect to our existing PLC?

Yes, after the control platform and interface requirements are reviewed. Provide the PLC model, protocol, electrical standard, I/O list and sequence of operation.

What positioning accuracy can be achieved?

There is no universal value. Accuracy depends on the feedback location, rope layers, drum diameter, load movement, structural compliance and control tuning. The target should be stated in the project specification and verified during commissioning.

How long can the remote drive shaft be?

The allowable length depends on torque, speed, shaft diameter, alignment and bearing support. Long shafts may require intermediate bearings, guards and torsional analysis.

Can the system be supplied as an OEM subsystem?

Yes. Mechanical interfaces, electrical panels, control boundaries and documentation can be defined around the host equipment manufacturer’s scope.

Is the listed 600 kg model suitable for every 600 kg application?

Not necessarily. Lift height, reeving, duty cycle, acceleration, drum layers and safety factors can change component selection even when the nominal load is the same.
