3000kg Twin Rope Synchronous Winch 10m/min | K Series | KLD

Medium-duty twin rope synchronous winch with a K-series hardened-tooth geared motor driving two grooved drums on a common shaft. Both ropes spool in a single layer between drum flanges, so the two ropes pay out together. Mechanical height limiter with adjustable set positions, and an electromagnetic brake with manual release. Case model PJK-3000: rated pull 3000kg, steel wire rope Ø14mm, stroke 1m, motor 7.5kW 4-pole with 141.93:1 reduction, drum speed 10.15rpm, rope speed 10m/min, drum Ø310mm. Outline A 998 × B 1184 × C 685 mm.

A 3000 kg twin rope synchronous winch built around a K-series hardened-tooth geared motor. Two grooved drums sit side by side on a common shaft, separated by a centre flange, and each rope spools in a single layer inside its own drum section — so both ropes pay out at the same rate from one drive. A mechanical height limiter with adjustable set positions stops the travel where you set it, and the electromagnetic brake can be released by hand for manual positioning. Rope speed 10 m/min at a drum speed of 10.15 rpm, stroke 1 m, steel wire rope Ø14 mm.

Quick Specs

Model: PJK-3000, rated pull 3000 KG
Steel wire rope: Ø14 mm
Stroke: 1 m
Motor: 7.5 kW, 4-pole (about 1440 rpm), with brake
Reduction ratio: 141.93 : 1

Application Scenarios and Applicable Boundaries

- Two-point lifting where the load must stay level: spreader beams, platens, frames, long fabrications
- Workshop and production line lifting at a fixed station
- Door, gate and hatch actuation where two ropes must move together
- Equipment mounted on a steel beam or platform, where the compact frame suits the structure
- Replacement of a single-rope hoist where two-point suspension is needed
- Test stands and fixtures needing repeatable travel between two set positions

Features Benefits

A K-series geared motor with hardened tooth flanks drives the drum shaft directly. Hardened gearing carries a higher tooth load in the same housing size than a soft-tooth unit, which is why a 7.5 kW frame can deliver 4562 N.m at the drum. The case reduction is 141.93:1, taking a 4-pole motor to a drum speed of 10.15 rpm.
The two grooved drums are machined side by side on one shaft with a centre flange between them. Because both drum sections turn as one body, the two ropes are driven from a single rotational reference — there is no second motor and no separate reducer that could fall out of step. The centre flange keeps the two ropes from migrating into each other's drum section.
Each drum section is grooved so the rope lays into a defined groove instead of cross-winding. With a single layer, the effective winding radius stays constant through the whole travel, so the rope speed does not change as the rope builds up — the rope at the top of the stroke runs at the same speed as at the bottom.

Size Installation and System Interface

1. The base frame has 68 mm slots rather than drilled holes, so the position can be adjusted along the slot when aligning to the structure. Use all four corner positions.
2. Mount on a flat, rigid surface. The frame is a welded box; bolting it to an uneven surface twists the frame and misaligns the drum shaft.
3. Design the supporting structure for the machine weight plus the 3000 kg rated pull. The machine weight is not stated in the source drawings — obtain it before finalising the structure.
4. Allow clear space on the motor side for the 1184 mm projection and for brake access, because the manual release lever has to be reachable.
5. Keep the rope lead within a few degrees of perpendicular to the drum axis. A side lead pulls the rope against the drum flange and the centre divider.
6. The two rope exits are set by the drum geometry. Confirm your load's suspension spacing before mounting, because this spacing cannot be changed on site without changing the drums.

Control Safety and Protection

The case machine is a direct-on-line or contactor-controlled unit: a 4-pole 7.5 kW motor through a 141.93:1 reducer gives a single rope speed of 10 m/min. There is no variable-frequency drive in the case configuration, so the speed is fixed unless a VFD is added as an option.
The brake is electromagnetic and is released by the motor's own control circuit when the motor is energised. When power is removed, the brake applies. A manual release lever allows the brake to be opened by hand.

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

Application: a fixed lifting station needing two-point suspension of loads up to 3000 kg over a 1 m stroke, where the load has to stay level as it moves.
Configuration supplied: twin rope synchronous winch PJK-3000. K-series hardened-tooth geared motor, 7.5 kW 4-pole, reduction 141.93:1, drum speed 10.15 rpm, rope speed 10 m/min. Two grooved drums Ø310 mm on a common shaft with a centre divider, single-layer spooling. Steel wire rope Ø14 mm. Mechanical height limiter with adjustable set positions. Electromagnetic brake with manual release. Base frame 598 × 472 mm with 68 mm mounting slots; overall 998 × 1184 × 685 mm.
Why this configuration: a short, fixed stroke with two ropes meant the simplest synchronism solution was one shaft carrying both drums, rather than two drives with an electronic link. Single-layer spooling keeps the rope speed constant over the 1 m travel, so the two ends of the stroke behave the same. The adjustable mechanical limiter lets the same unit serve different fixtures by resetting the stops.
