The MARSHINE MAR-AC2500 Portable Capstan Winch Electric Cable Puller is designed to simplify these demanding cable installation tasks. Powered by a high-performance electric induction motor, it features dual capstan heads that provide two pulling capacities and rope speeds, allowing operators to select the most suitable configuration for different cable sizes and installation conditions. Unlike a conventional drum winch, the capstan design allows continuous rope travel, making it ideal for long-distance cable pulling operations. The machine also incorporates a heavy-duty tubular frame, removable transport wheels, foot pedal control, overload protection, and an electromagnetic fail-safe brake for improved safety and ease of use.
Understand How the Capstan Winch Works
Before using the machine, it is important to understand its operating principle. Unlike a drum winch, the MAR-AC2500 does not store the pulling rope on the capstan. Because the rope moves continuously through the capstan, the pulling distance is limited only by the rope length rather than the drum capacity, making the machine well suited for long cable installation projects.
So How To Use This Machine?
Inspect the Equipment
Before each operation, carry out a complete inspection of your MARSHINE MAR-AC2500 Portable Capstan Winch Electric Cable Puller. Check the following items:
Electric motor and power cable;
Foot control switch;
Capstan drums;
Gear transmission;
Protective frame;
Rope storage reel;
Carry handles and removable wheels;
Anchor points and shackles;
Emergency stopping function;
Also inspect the pulling rope for cuts, abrasion, broken fibers, or excessive wear. Please noted do not operate the machine if any component is damaged.
Position and Secure the Machine
Transport the cable puller to the work area using the removable wheels or integrated carrying handles. Once positioned, please:
Remove the transport wheels if required.
Place the machine on firm, level ground.
Align the capstan with the pulling direction.
Secure the frame using the integrated anchor shackles, chains, straps, or ground stakes while proper anchoring prevents movement while the machine is under load and allows the capstan to transmit pulling force efficiently.
Select the Appropriate Capstan Head
The MARSHINE MAR-AC2500 Portable Capstan Winch Electric Cable Puller is equipped with two capstan drums. Each drum provides a different combination of pulling force and rope speed. Generally:
The small capstan provides higher pulling force with a lower rope speed.
The large capstan provides a faster pulling speed with a lower pulling force.
Select the capstan that best matches the cable weight, route conditions, and installation requirements before threading the rope.
Install the Pulling Rope
Use a high-strength double-braided polyester pulling rope of the recommended diameter and strength. To install the rope:
Feed the rope toward the selected capstan.
Wrap the rope around the capstan drum.
Maintain at least three complete wraps around the capstan to generate sufficient friction.
Route the rope through the lead roller.
Connect the rope to the pulling grip or swivel attached to the cable.
Ensure the rope is clean, untwisted, and properly seated before starting the pull.
Connect the Cable
Attach the pulling rope to the cable using suitable accessories and verify that every connection is secure before applying tension. A proper connections help prevent accidental disconnection during pulling.
Connect the Power Supply
The MARSHINE MAR-AC2500 Portable Capstan Winch Electric Cable Puller is available in 110 V and 240 V single-phase versions. Before switching on the machine, you need to:
Confirm the supply voltage matches the machine rating.
Check that the power cable is undamaged.
Ensure all electrical connections are dry and secure.
Once connected, switch on the power and confirm the controls respond correctly before beginning the pulling operation.
Begin Pulling
Use the foot-operated control to start the capstan. The foot pedal allows the operator to:
Start the machine smoothly.
Stop the pull instantly when required.
Keep both hands free to guide the rope and monitor the cable.
Then increase pulling speed gradually to avoid shock loading and maintain a steady pulling speed throughout the installation to reduce stress on both the cable and the pulling equipment.
Monitor the Pulling Operation
During cable installation, continuously observe the rope alignment, capstan wraps, cable movement, pulling speed, anchor stability, or cable rollers along the route and stop the operation immediately if the rope slips on the capstan, the cable becomes snagged, unusual vibration or noise occurs, and if overload protection is activated. The continuous monitoring helps ensure a safe and efficient installation.
Complete the Pull
Once the cable reaches its final position, please:
Release the foot control.
Allow the machine to stop completely.
Disconnect the pulling rope.
Remove the pulling accessories.
Wind the rope neatly onto the storage reel.
