Dual Rope Linear Winch 700kg 304 SS with SEW Motor | KLD

Engineered for synchronized twin-rope lifting and lowering duties. Two stainless steel ropes on a grooved drum keep both sides moving together, while the 304 stainless steel body suits humid and corrosive environments. SEW geared motor with VFD control provides quiet, adjustable-speed operation. Rated lifting capacity 700 kg in a compact linear layout.

Quick Specs

Lifting capacity: 700 kg
Ropes: 2 × Ø8 mm stainless steel (synchronized)
Rope speed: 6.5 m/min (VFD adjustable to 3 m/min)
Motor: 1.5 kW SEW geared motor, 3-phase 380V 50Hz
Body: 304 stainless steel

Application Scenarios and Applicable Boundaries

- Twin-rope work platforms & baskets — synchronized lifting and lowering of platforms, baskets or fixtures where two ropes keep the load level and stable.
- Stage & presentation machinery — dual-point vertical movement of screens, trusses or scenery with synchronized rope travel.
- Corrosive & humid environments — plating shops, chemical plants and coastal facilities, where the 304 stainless steel body and stainless steel ropes reduce corrosion concerns.
- Precise two-point lifting — low-speed lifting and lowering of equipment requiring two independently visible, synchronized rope ends.

Boundary: The standard configuration is not intended for personnel lifting unless the complete system (platform, safety devices) is engineered and certified for that duty. Confirm the load, rope arrangement and environment before ordering.

Features Benefits

1.Synchronized twin-rope operation — Two ropes wound on one drum travel together, supporting level and stable lifting of wide or long loads, and reducing skew during travel when the system is correctly rigged.
2.Orderly rope layering — The grooved drum guides each rope into defined grooves, helping maintain even layers and support synchronized payout, reducing rope misalignment and slack during operation.
3.Orderly rope layering — The grooved drum guides each rope into defined grooves, helping maintain even layers and support synchronized payout, reducing rope misalignment and slack during operation.
4.Orderly rope layering — The grooved drum guides each rope into defined grooves, helping maintain even layers and support synchronized payout, reducing rope misalignment and slack during operation.

Complete Technical Specifications

Size Installation and System Interface

The winch is supplied on a stainless steel base plate with pre-drilled mounting holes (center-to-center 800 mm) for floor fixing. Overall dimensions, rope exit direction and mounting orientation are confirmed on the general arrangement drawing after configuration approval.

Available interfaces include: motor power terminals, VFD control, height limiter contacts, and optional limit switch, encoder or remote control. Electrical interfaces are defined in the final wiring diagram.

Control Safety and Protection

- Normal control: VFD control with rope speed adjustable from 6.5 to 3 m/min.
- Travel protection: height limiter for upper/lower limit setting; optional limit switch contacts for external interlocking.
- Stopping & holding: brake performance and holding behavior confirmed in the control scheme for the configured duty.
- Twin-rope safety: both ropes travel on one grooved drum, supporting synchronized payout; rope condition is to be inspected per the operation manual.
- Environment: 304 stainless steel body for humid/corrosive atmospheres; confirm temperature range and site conditions before ordering.

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

Customization Options and Engineering Process

Configured around your operating conditions — Share the required lifting load, rope travel and diameter, operating speed, duty cycle, power supply, installation envelope and environment. KLD will review the application and provide a proposed configuration, technical drawing and quotation for approval.

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.

Factory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, twin-rope synchronization check, limit 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 facility needed synchronized two-point lifting of a work platform with corrosion-resistant construction in a humid environment.
Solution: A dual-rope linear winch (700 kg class) with grooved drum, 304 stainless steel body, SEW geared motor and VFD control, configured with the required rope length.
Outcome: The winch passed the customer's functional acceptance procedure for the planned platform duties.
