Hydraulic winch · Mainly custom-built
NJ Series Compact Hydraulic Winch
A small hydraulic winch built from a BM2 orbital motor, planetary gearbox, multi-disc brake and drum, with grease-lubricated internals in a compact package. There are two series: NJ1.75, mounted between two side plates, and JSJ1.75, with its own base frame. Drum, mounting and ports can all be customized to the machine.
Rope 7–10 mm, 4-layer rope capacity 34.3–54 m; multi-disc brake with 360 N·m static braking torque; weight 30 kg (NJ1.75), 38 kg (JSJ1.75).
Technical data
NJ Series model data
Pull, rope speed and rope capacity are given for each drum layer: pull is highest on the 1st layer, rope speed is highest on the 4th. Enter the pull and rope speed you need to highlight the models that reach both on the same drum layer.
No catalog model reaches both on the same drum layer. We can build to the pull, rope speed and rope capacity you need. Send us your duty →
Layers: pull, rope speed and rope capacity are given for each of drum layers 1–4.
Operating notesSame for both series
1Not for lifting or transporting persons.
2Multi-disc brake, static braking torque 360 N·m.
3Internal parts are grease-lubricated.
4Max. return-line back pressure 0.5 MPa.
5For safety, keep at least 4 wraps of rope on the drum.
6Fix the winch with bolts of property class 8.8 or higher.
