Application Scenarios and Applicable Boundaries

- Stacker cranes — high-speed lifting and transporting of goods in warehouse and logistics systems.
- Warehousing & logistics — efficient lifting with large stroke and carrying capacity for different scenarios.
- Stage applications — SEW motor drive suits stage and storage-logistics fields (per the SEW motor advantage).
- Custom configurations — rope length, speed and pulling force customizable; 3D data and collective painting available.

Boundary: The standard configuration is not intended for personnel lifting. Confirm the load, rope, duty cycle and environment before ordering.

Features Benefits

Automated precision control — The PLC control system enables automated operation and more precise control, supporting higher working efficiency and safety.
Reliable, durable drive — SEW motors as output power provide high reliability and durability; high efficiency, low noise and low energy consumption help reduce operating cost and support longer service life.
Safe hoisting protection — The electromagnetic brake guards every hoisting operation, supporting safe lifting.
Easy maintenance — Modular design supports quick disassembly and easy maintenance.

Complete Technical Specifications

Size Installation and System Interface

The winch is supplied on a base plate with pre-drilled mounting holes for stacker-crane or floor installation. Overall dimensions, mounting orientation and rope outlet direction are confirmed on the general arrangement drawing after configuration approval.

Available interfaces include: motor power terminals, PLC communication, electromagnetic brake control, built-in speed limiter, and optional encoder and main-shaft limit switch, pendant remote, limit switch, rope guide and slip ring. Electrical interfaces are defined in the final wiring diagram.

Control Safety and Protection

- Normal control: PLC smart control for automated operation and precise control.
- Stopping & holding: electromagnetic brake supports safe stopping; holding behavior confirmed in the control scheme.
- Speed protection: built-in speed limiter.
- Rope synchronization: grooved drum design supports synchronized dual-rope operation; rope length, speed and pulling force configurable.
- Travel protection: encoder and main-shaft limit switch available as options for defined travel.
- Environment: confirm temperature range and site conditions before ordering.

Standard vs optional items are confirmed on the control scheme for each order.

Standards Testing and Quality

The company operates an ISO 9001 quality management system. CE conformity documents (LVD, EMC) are available for applicable configurations on request. Classification certificates (e.g. LRS / BV / ABS / DNV GL) can be arranged as an optional item for marine applications.

Factory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, brake function, limiter function and control verification. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.

Engineering Cases

Challenge: A warehousing project required a high-speed dual-drum winch for stacker cranes — synchronized dual-rope lifting, PLC automation, reliable braking and large stroke.
Solution: High-speed dual-drum winches (4000 kg class) with PLC smart control, SEW motors, electromagnetic brake, modular design and built-in speed limiter, configured for the stacker application.
Outcome: The winches passed the customer's functional acceptance procedure for the planned lifting duties.
