Whether it is a one-to-two flat-panel wrecker or a tow-lift combined wrecker, the hydraulic winch is an essential accessory. It is mainly used for lifting and towing traction in the wrecking operation. The more commonly used are turbine worm and There are two structural forms of planetary reducer. The turbo-worm hydraulic winch has a relatively simple structure, and its transmission efficiency and production cost are relatively low. It is generally used for medium-sized hydraulic winches, while the planetary hydraulic winch has a relatively complex structure and a large transmission ratio. The efficiency and production cost are relatively high, and it is generally suitable for medium and heavy hydraulic winches.

The installation methods of hydraulic winches are mostly center-mounted and side-mounted. Generally, one or two winches are installed on a wrecker. The winch's rope output method can be upper and lower. In order to prevent the wire rope from disordering the rope, the winch is generally equipped with There is pressure guide rope device. The installation of hydraulic winch is related to the technology and safety performance of the vehicle, so you need to pay attention to the following points during installation and use:

1. Before installing the winch, check whether the parts are complete and whether there is any damage. If there is any damage, it must be replaced.

2. The link between the winch and the connecting support or bracket should be fixed with high-strength bolts with a mechanical performance of 10.9 or above to ensure sufficient connection strength.

3. After the winch is installed, check whether the hydraulic pipeline is connected incorrectly and whether the clutch can be combined and separated normally. Whether the winch drum can rotate normally without jamming.

4. When winding the wire rope on the winch, put the rope head into the rope hole of the drum, then tighten the screws, and in the rope-rewinding condition, after winding 4 to 5 times, load the wire rope with a force of 3 to 5 kN tight.

5. The maximum deflection angle when the wire rope is wound into and out of the reel should not exceed 3 degrees to prevent the rope disorder and the winch's deflection. When it is out of service, the rope press should compress the wire rope to prevent the wire rope from returning loose. And messy rope.

6. After the winch is installed, run it without load before the heavy load test or when it is not used for a long time, so that the motor can run smoothly.

7. It is strictly forbidden to disengage the winch clutch when the wrecker is lifting heavy objects or pulling. When the winch is working, the steel wire rope should be kept at least 5 turns on the drum.

8. The hydraulic winch is strictly prohibited from overloading to prevent damage to the winch and safety accidents.
