According to the driving mode, application scenarios, and structural characteristics, hydraulic winches mainly have the following applicable solutions, which are designed based on their characteristics and engineering requirements:

1、 Low speed direct drive scheme (direct drive of low-speed hydraulic motor)

Applicable scenarios:

Mobile devices with limited space (such as loaders and coal mining machinery): Low speed hydraulic motors can be directly installed on the drive shaft, reducing transmission links and saving installation space.

Scenarios requiring self-locking protection: self-locking function is achieved through worm gear transmission to prevent load slippage, suitable for mine lifting, inclined shaft transportation, etc.

Small winch design: The drive part is connected to the working device, with a compact structure, suitable for underground or narrow space operations.

Advantage:

Reduce power loss: eliminate intermediate transmission links (such as gears and sprockets) to improve system efficiency.

Reduce noise: Avoid mechanical noise caused by friction of transmission components.

Simplified maintenance: Short transmission chain, fewer fault points, and low maintenance costs.

case

Mine transportation winch: adopting a low-speed direct drive scheme, directly driving the drum to achieve stable lifting of the mining car in the inclined shaft.

Ship mounted positioning winch: directly controls the release and retraction of anchor chains through low-speed motors to ensure the accuracy of ship berthing.

2、 High speed deceleration scheme (driven by high-speed hydraulic motor and reducer)

Applicable scenarios:

Large winches or scenes with ample space, such as container lifting at ports and building hoisting, require the use of reducers to share torque and load.

Scenarios that require multi-level speed regulation: speed grading is achieved through reducers to adapt to different load requirements.

High load operation: The reducer can disperse the radial and axial loads borne by the hydraulic motor, extending the service life of the equipment.

Advantage:

Reduce motor requirements: High speed motors have lower costs and are matched with load torque through reducers.

Flexible transmission: Gear, sprocket and other reducers can be selected to adapt to different working conditions.

Protect the motor: Avoid direct impact loads on the motor and reduce the failure rate.

case

Terminal cargo container lifting winch: high-speed motor+planetary reducer, realizing fast lifting of large tonnage containers.

Construction industry hoisting winch: meets the vertical transportation needs of high-rise building materials through multi-stage reducers.

3、 Independent drive and pipeline connection scheme

Applicable scenarios:

The application site has limited space: for example, in underground operations, the driving part and the working device are placed independently and connected through hydraulic pipelines.

Scenarios that require remote control: such as mooring winches on offshore platforms, driving units away from the work area to reduce vibration and noise effects.

Modular design requirements: facilitate equipment upgrades and maintenance, reduce downtime.

Advantage:

Flexible arrangement: The driving part is separated from the working device to adapt to complex terrain.

Easy to operate: Power is transmitted through pipelines to reduce on-site interference.

High safety: The independent drive unit can be equipped with protective devices to reduce operational risks.

case

Underground hydraulic winch: The drive unit is located in a safe area and controls the operation of the underground winch through hydraulic pipelines.

Marine cable tightener: The driving part is installed on the deck and controlled by long-distance pipelines to retract and unwind the ship's side cables.

4、 Explosion proof hydraulic winch scheme

Applicable scenarios:

Flammable and explosive environments, such as acetylene production, water and gas manufacturing, and mining operations, must meet explosion-proof requirements.

High risk industrial sites: chemical, oil and gas extraction and other fields, need to prevent accidents caused by electrical sparks.

Advantage:

Intrinsic safety: Hydraulic drive does not require explosion-proof motors, reducing electrical hazards.

High reliability: The hydraulic system has strong overload protection and is suitable for harsh working conditions.

Less maintenance: simple structure, low failure rate, and reduced downtime risk.

case

Mine hoisting winch: adopts explosion-proof hydraulic system to ensure the safe transportation of personnel and materials in the mine.

Chemical plant hoisting winch: In flammable gas environments, equipment installation and maintenance are achieved through hydraulic drive.

5、 Composite transmission scheme (hydraulic+mechanical hybrid drive)

Applicable scenarios:

Scenarios that require precise control, such as textile machinery spool winding and cable production spool drive, require a combination of hydraulic and mechanical transmission to achieve speed synchronization.

Multi working condition adaptation requirements: For example, for mining winches, the transmission mode needs to be flexibly adjusted on flat or sloping surfaces.

Advantage:

Strong controllability: The hydraulic system provides stable power, and the mechanical transmission achieves precise speed regulation.

Strong adaptability: switchable transmission mode to adapt to different operating conditions.

Efficiency optimization: Combining hydraulic and mechanical advantages to reduce energy consumption.

case

Textile machinery reel winch: The hydraulic motor drives the spindle, and the mechanical transmission device achieves precise control of wire speed.

Crawling winch: Hydraulic transmission provides basic power, and mechanical clutch switches between crawling and backfilling modes.
