Manual-and-Electric Servo Winch for Engineering Labs and Training Systems

LYFOOCRANE Laboratory Motion-Control Equipment

Manual-and-Electric Servo Winch for Engineering Labs and Training Systems

A dual-drum teaching and research platform that combines programmable servo motion with a separate hand-crank operating mode. It supports demonstrations of drive control, rope handling, transmission behavior and multi-drum operation in one configurable machine.

One Platform for Motion Control and Mechanical Demonstration

This winch is intended for laboratories, research rigs and specialized training equipment where users need to observe both powered and manual drive behavior. In electric mode, the servo motor and PLC can control speed, direction, travel and programmed sequences. After the electric drive is safely isolated, a clutch arrangement allows the mechanism to be operated by hand for setup, demonstration or controlled adjustment.

Programmable Servo Motion

Develop demonstrations around speed profiles, position commands and automated sequences.

Isolated Manual Mode

A clutch-selected hand-crank mode supports manual adjustment after powered operation is disabled.

Flexible Dual Drums

The two drums can be configured for independent or coordinated operating demonstrations.

Adaptable Lab Interface

Controls, labels, mounting points and I/O can be tailored to the teaching bench or test system.

What the System Can Demonstrate

Motion

Servo Speed and Position Control

Create exercises involving adjustable speed, acceleration, direction, travel and target positioning.

Logic

PLC Sequence Development

Integrate switches, limits, interlocks and programmed operating steps into laboratory exercises.

Mechanics

Worm-Gear Transmission

Observe high reduction ratios and resistance to back-driving under defined test conditions.

Mode Selection

Powered and Manual Operation

Demonstrate how the drive is isolated and the mechanism is transferred to hand-crank control.

Rope Handling

Grooved Dual-Drum Winding

Study rope path, drum geometry and independent or combined drum configurations.

Protection

Travel-Limit Integration

Use adjustable limit devices as part of the control and safety-interlock architecture.

Drawing applies to the reference model. Final dimensions may change with capacity, drum size, rope storage and mounting requirements.

Manual / Electric Mode-Change Concept

Manual operation is a separate machine state—not a simultaneous backup drive. The final control system should prevent the servo motor and hand crank from driving the mechanism at the same time.

1. Stop and SecureBring the load to a controlled stop and verify the mechanism is safely held.
2. Isolate Powered MotionDisable servo operation through the approved control and isolation sequence.
3. Select Manual ModeTransfer the clutch mechanism only after the system confirms a safe state.
4. Operate Under SupervisionUse the hand crank within the approved load and travel limits.

Safety note: Worm gearing can resist back-driving, but it must not automatically be treated as a certified load-holding brake. Suspended-load applications require an engineered braking and safety system appropriate to the risk assessment and applicable regulations.

Laboratory Project FAQ

Can students program the PLC?

Yes. The control system can be configured for instructor-approved exercises, from preset operating sequences to more advanced PLC programming and I/O integration.

Can manual and electric operation be used at the same time?

No. They should be treated as separate, interlocked operating states. Powered motion must be stopped and isolated before the system is transferred to hand-crank mode.

Does the worm gearbox replace a brake?

Not automatically. Back-driving behavior depends on geometry, efficiency, lubrication, wear and vibration. If the machine handles a suspended load, an independently engineered holding and braking arrangement should be specified.

Can the two drums run separately?

Independent or coordinated operation can be configured. The required sequence and whether true synchronization is needed must be defined during control-system design.

Can the machine be supplied with English teaching labels?

Yes. Component identification, operating steps, rope direction and safety labels can be designed around the course content and local requirements.
