Core Functions and Applications
A turbo coupling (also known as a hydraulic coupling) is a key power transmission component widely used in marine, industrial, and heavy-duty machinery. It transmits power between the motor and working machine (such as pumps, fans, winches, and conveyors) through the flow of hydraulic oil, acting as a “flexible connector” to buffer load impacts and protect the drive system.
- Power transmission with flexibility: Transmits torque smoothly via hydraulic oil circulation, avoiding rigid connections between motor and equipment to reduce mechanical shock.
- Load buffering & protection: Absorbs startup and operational shocks, prevents motor overload during equipment startup, and extends the service life of motors, gears, and other components.
- Speed regulation & energy saving: Adjusts output speed by changing the oil filling amount (for variable-speed models), optimizing operation efficiency and reducing energy consumption in variable-load scenarios.
- Multi-scenario adaptation: Commonly used in marine auxiliary machinery (pumps, blowers), industrial conveyors, mining machinery, and port winches, especially suitable for heavy-load startup and continuous operation equipment.

Core Functions and Applications
A cable drum (also called a cable reel) is a key storage and transmission component for cables in marine, industrial, and port equipment. It is designed to wind, store, and release power cables or signal cables synchronously with the movement of equipment (such as cranes, winches, and mobile machinery), ensuring orderly cable management and stable power/signal transmission during equipment operation.
- Cable storage & organization: Neatly winds and stores long cables to avoid tangling, twisting, or damage caused by random placement.
- Synchronous retraction: Automatically retracts or releases cables following the equipment’s lifting, traversing, or rotating movements, maintaining appropriate cable tension.
- Transmission protection: Protects cables from external friction, impact, or environmental erosion during transmission, extending cable service life.
- Multi-scenario adaptation: Widely used in marine equipment (ship cranes, offshore platforms, marine winches), port machinery (gantry cranes, container handlers), and industrial equipment (mobile conveyors, construction machinery), especially suitable for equipment requiring frequent movement with cable connection.

Core Functions and Applications
SMAG grab accessories serve as key components for SMAG electro-hydraulic and hydraulic remote-controlled grabs. They encompass all parts needed for the grab’s driving, control, load-bearing, and connection functions, which are essential to ensuring smooth and efficient bulk cargo handling at ports. With 100% compatibility with original SMAG grabs, these accessories can be directly substituted for old or faulty parts.
