JSJ Series — Hydraulic Winches
Short Description:
JSJ hydraulic winches are custom pulling, lifting and towing winches with motor, planetary gearbox, brake, valve and drum options.
JSJ hydraulic winches are custom pulling, lifting and towing winches with motor, planetary gearbox, brake, valve and drum options.
| Selection Item | Typical JSJ Series Range / Option | Why It Matters |
|---|---|---|
| Rated line pull | From small custom units to about 600 kN | Defines motor torque, gearbox ratio, drum strength and brake capacity. |
| Rope diameter | Approx. 8 mm to 60 mm, project dependent | Determines drum groove, rope capacity and spooling layout. |
| Rope capacity | From a few meters to 1000+ m | Affects drum diameter, drum length, rope layers and winch envelope size. |
| Line speed | Configured according to flow and load | Controls productivity, heat generation and operator handling accuracy. |
| Working pressure | Commonly 16 to 25 MPa, custom options available | Determines motor displacement and hydraulic system compatibility. |
| Drive layout | Hydraulic motor + planetary gearbox + drum | Provides compact high-torque output for heavy pulling or lifting. |
| Brake system | Spring-applied, hydraulically released multi-disc brake | Supports load holding, safer lowering and parking under load. |
| Control valve options | Balance valve, relief valve, distributor, speed control options | Improves load control, circuit protection and smooth operation. |
| Mounting | Base frame, flange, custom hole pattern or machine interface | Allows the winch to fit cranes, drilling rigs, marine decks or special equipment. |
| Environment | Industrial, mining, marine, offshore and outdoor duty | Guides coating, sealing, material and maintenance choices. |
Engineering Notes
- Always define rated line pull by rope layer. First-layer pull is higher than outer-layer pull.
- For lifting applications, brake safety factor, load-holding requirements and local regulations must be checked carefully.
- High line speed requires enough hydraulic flow and proper oil cooling to avoid overheating.
- Multi-layer spooling should consider rope fleet angle, rope pressure and drum groove design.
Typical Applications
- Crawler cranes and piling rigs: main or auxiliary pulling, lifting and positioning tasks.
- Rotary drilling rigs: controlled rope handling in drilling and foundation equipment.
- Marine and offshore equipment: deck winches, mooring, towing and handling systems with corrosion protection options.
- Mining and tunneling machinery: heavy pulling, equipment recovery and underground material handling.
- Forestry and logging: pulling, dragging and positioning logs or equipment in harsh outdoor conditions.
- Vehicle-mounted recovery systems: custom recovery winches for trucks, trailers and special vehicles.
- Industrial lifting and pulling: steel plants, shipyards, construction sites and custom hydraulic machinery.
Best-Fit Buyer Profile
JSJ Series hydraulic winches are best suited for OEMs, equipment rebuilders, hydraulic system integrators and project buyers who need a winch matched to a specific machine rather than an off-the-shelf catalog unit.

JSJ Series hydraulic winches are custom-built pulling, towing, lifting and hoisting winches for marine, mining, construction, drilling, forestry and industrial equipment. Each winch can be engineered around the required line pull, rope diameter, rope capacity, working pressure, hydraulic flow, duty cycle, braking method and installation space.
Why Choose JSJ Series Hydraulic Winches
- Wide pulling range: JSJ winches can be configured from compact utility winches to heavy-duty units up to about 600 kN rated line pull.
- Integrated hydraulic drive: hydraulic motor, planetary gearbox, multi-disc brake, balance valve, distributor and drum can be supplied as one tested assembly.
- Custom drum and rope capacity: drum diameter, drum length, rope groove, rope outlet direction and rope capacity can be adapted to the machine layout.
- Stable braking and load control: spring-applied hydraulic release brakes and balance valves support safer holding, lowering and positioning under load.
- Compact planetary reduction: high torque density helps fit strong winch performance into limited installation space.
- OEM and replacement design support: JST can develop winches for new equipment or replacement projects where imported winches are difficult to source.
How to Select a JSJ Hydraulic Winch
For accurate selection, send the working conditions instead of only asking for a model number. The most important parameters are:
- Rated line pull: specify the required pulling force and whether it is first-layer or outer-layer line pull.
- Rope diameter and rope length: these decide drum size, rope layers and fleet angle requirements.
- Line speed: provide target speed at load and available hydraulic flow.
- Hydraulic pressure and flow: working pressure, peak pressure and flow rate determine motor displacement and gearbox ratio.
- Duty cycle: occasional pulling, frequent lifting, marine service and mining duty require different thermal and braking margins.
- Mounting space: share drawings, hole pattern, shaft direction, rope outlet and surrounding clearance.
- Control requirements: manual valve, hydraulic control, remote control, load holding, emergency release and speed control options can be integrated.
Common Custom Options
- Grooved or plain drum for single-layer or multi-layer spooling
- Base frame, flange mounting or special machine interface
- Hydraulic motor options for different flow and speed ranges
- Multi-disc brake, balance valve, relief valve and anti-cavitation valve options
- Marine coating, corrosion protection and enhanced sealing for harsh environments
- Custom rope outlet, fairlead, pressure roller or level-wind arrangement

FAQ
Can JST design a hydraulic winch from my drawing?
Yes. Send the installation drawing, line pull, rope diameter, rope capacity, hydraulic pressure and flow. JST can design the drum, gearbox, motor, brake and valve configuration around the machine interface.
What information is needed for a quotation?
At minimum, provide rated line pull, rope diameter, rope length, target line speed, available pressure and flow, mounting dimensions, working environment and whether the winch is used for pulling or lifting.
Can JSJ winches replace imported hydraulic winches?
In many projects, yes. JST can compare mounting dimensions, drum data, hydraulic parameters and braking requirements to develop a compatible replacement or optimized alternative.
Are JSJ winches suitable for marine use?
Yes. Marine and offshore versions can use anti-corrosion coating, improved sealing, stainless fittings and suitable brake or valve options according to the working environment.
