For a "behemoth" like a yacht, many novice ship owners may ask how maintenance is carried out? well， The annual maintenance of a yacht includes machine maintenance, including propulsion, generator, air conditioning and other electrical systems, as well as hull maintenance. Hull maintenance requires the entire ship to leave the water surface, so it is necessary to consider where to choose and how to arrange it!
How many ways are there to row a yacht? Due to the unique characteristics of yachts, there are currently four main types of hoisting for medium and large yachts internationally: boat crane, ramp type yacht hoist, rotating boom, and guide rail slide. The mobile boat crane (abbreviated as yacht crane or gantry crane) is at the forefront of yacht hoisting due to its unique design, safety, and convenience. The Xunliao Bay International Yacht Club Yacht Repair Service Center on Financial Street uses a 100 ton/85 foot standard mobile boat crane.

Most foreign yachts are lifted using mobile boat cranes, while in China, due to the late introduction of technology, single point lifting was used in the past. However, in fact, 99% of yacht docks worldwide have chosen mobile boat cranes to provide lifting services for the upper and lower rows of yachts. Unless objective conditions are not met, mobile yacht engines are usually an optional solution. Looking back at history, yacht cranes appeared in the 1970s. Shortly after its birth, the yacht crane became popular in ship docks around the world, and it is a reliable helper for dock services. At present, it has been applied worldwide for nearly 40 years, with mature and stable operation, and is almost an optional way for large and medium-sized yachts to row up and down.
Three key points in the design of yacht cranes
1. The maximum load exceeds the rated load by 120%
It ensures that lifting yachts within the load weight is very safe. And equipment exceeding the rated load is lifted, so even if the machine itself estimates the tonnage of the yacht incorrectly, the equipment will not be forced to lift, thus avoiding accidents of overweight!

2. Controllable lifting point position, lifting according to yacht lifting point, precise operation
Its design meets the requirements of ship design, with marked lifting points on the hull for easy operation. Each lifting point can be adjusted to control the distance of the sling and the levelness of the hull.

3. Hugging and non squeezing care yacht
The lifting method of sling is similar to lifting the hull, without squeezing the hull, and there is no squeezing phenomenon of ordinary single arm crane on the hull.

In addition, yacht cranes have many advantages: they do not occupy a ranking, and the cost of arranging is low; Cooperate with the activity boat frame for convenient construction; Small supporting contact area, no need for displacement, safe, fast, and cost-effective. Although the design of the yacht crane has been simplified as much as possible, the horse still needs a rider. The upper and lower rows of yachts must be equipped with well-trained full-time personnel who possess proficient operational skills and practical experience. At present, all yacht clubs in China have been in line with international standards and basically choose mobile boat cranes to provide upper and lower row services for dock yachts.
Introduction to other lifting methods
1. Rotating boom. Advantages: Flexible arm position and small footprint; Disadvantage: There is a significant security risk.
2. Slope type yacht hoist is more suitable for use on small and medium-sized yachts.
3. Guide rail slide traction: It belongs to the old style of ship landing method, requiring a sloping ramp, occupying a large area, time-consuming traction, and difficult to ensure the balance of the hull, which has a significant impact on the hull.
Tips for upper row maintenance process
1. Cleaning and polishing the bottom of the ship,
2. Replace the entire set of zinc blocks,
3. Refresh the anti fouling protective paint on the bottom of the ship,
4. IPS propeller refreshes spiral metal protective paint.
In the coming days, the yacht repair service center equipped with a 100 ton/85 foot standard gantry crane, a 10 ton/30 foot imported forklift from the United States, an outdoor work area of approximately 4600 square meters, and an indoor repair workshop of approximately 680 square meters will continue to provide customers with * * boat maintenance and daily repair services.
