Twin Rope Synchronous Winch 50kg Dual Drum Dyneema Rope | KLD

A twin rope synchronous winch built with a dual-zone automatic rope guide so both ropes wind in orderly layers with reduced risk of tangling. Wired handle and wireless remote give two control options, and the unit can also be driven by hand crank, providing a manual-electric dual-mode capability for convenient operation.

Quick Specs

Model: TH2425.00 (50 kg)  |  Lifting weight: 50 kg  |  Machine weight: 55 kg
Motor: single-phase 240 V, 0.2 kW  |  Gearbox ratio 100:1  |  Output speed 15 r/min
Rated output torque: 90 N·m  |  Rope speed: 6–11 m/min

Application Scenarios and Applicable Boundaries

- Twin-point lifting where two ropes must rise together — the synchronous twin rope payout keeps both ropes winding evenly.
- Duties needing orderly rope winding — the dual-zone automatic rope guide reduces the risk of rope tangling, and is especially useful with soft, low-stretch Dyneema rope.
- Sites with limited or no power — hand-crank drive allows operation without a mains supply.
- Multi-operator or mixed-position working — wired handle plus wireless remote for flexible control.
- Portable / mobile use — carry handles on both sides and a machine weight of 55 kg.
- Equipment lifting in general industrial, marine-adjacent and research settings.

Boundary: the case unit is rated 50 kg with Ø8 mm Dyneema rope, 100 m per drum section, rope speed 6–11 m/min and a single-phase 240 V supply. Load, speed, rope length, control mode, mounting, rope exit direction and material are customized per site; protection, durability and safety design are also developed per application. Confirm the load, rope type, travel, supply voltage and environment before ordering. Standard configuration is not intended for personnel lifting.

Features Benefits

Two ropes in step — twin rope payout winds the ropes more steadily and evenly, improving working efficiency.
Orderly winding — the dual-zone automatic rope guide lays the rope in tidy layers and reduces the risk of rope tangling, lowering the chance of an operational interruption.
Two ways to control — wired handle and wireless remote operate the same unit, making operation more flexible and convenient to suit different working situations.

Complete Technical Specifications

Size Installation and System Interface

Outline (case, per detail page): 649 × 280 × 541 mm (A length × B width × C height); drawing overall length 708.5 mm including guard and shaft extension — confirm on the approved GA drawing.
Mounting: base plate with mounting provision; the drum assembly sits between left and right support assemblies on a common base.
Rope interface: Ø8 mm Dyneema rope, 100 m per drum section; dual-zone automatic rope guide (rope follower assembly) distributes the two ropes across their own zones.
Drive: single-phase 240 V, 0.2 kW motor-gearbox (WSF25-0.2kW-100-4P) with chain transfer (05B single-row chain, small and large sprockets) to the drum.
Control interface: wired handle and wireless remote; hand-crank drive for manual operation.
Electrical: single-phase 240 V supply; confirm the supply and plug type for your market before ordering.

Control Safety and Protection

- Control: wired handle and wireless remote as a dual control arrangement; hand-crank drive provides a manual-electric dual mode.
- Winding: dual-zone automatic rope guide lays the two ropes in orderly layers, reducing the risk of rope tangling.
- Drive protection: chain guard covers the chain and sprocket drive; winch guard assembly covers the rotating drum area.
- Bearings: dust-cover bearings (61908-Z, 6005-Z) on the drum and support assemblies.
- Corrosion: stainless steel fasteners (1Cr18Ni9Ti) throughout; orange topcoat finish (f07e49).
- Optional: limit switch, encoder with main-shaft limit switch, VFD control panel, pulley, grooved drum, drum divider flange, winding device, rope follower, pendant remote control, manual emergency crank, class certificates (LRS / BV / ABS / DNV GL).
- Personnel lifting excluded unless a dedicated man-rated system is specified.

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

a twin rope synchronous winch required for twin-point lifting where two ropes must rise together and remain neatly wound. The site had limited power availability in some working positions, and operators needed to control the unit from different locations.

Solution: TH2425.00 twin rope synchronous winch — dual drum with a dual-zone automatic rope guide to keep the two ropes in orderly layers and reduce tangle risk; single-phase 240 V, 0.2 kW motor-gearbox (WSF25-0.2kW-100-4P) with 100:1 ratio, 90 N·m rated output torque and 6–11 m/min rope speed; Ø8 mm Dyneema rope with 100 m per drum section on a 121 mm drum; wired handle plus wireless remote control; hand-crank drive for no-power operation; carry handles on both sides. Case machine weight 55 kg; outline 649 × 280 × 541 mm.

Outcome: the unit met the project's lifting weight, twin-rope synchronization and rope-winding requirements, and passed the customer's acceptance procedure.
