The design of all YFM maritime cranes is rooted in the specific conditions of marine applications: harsh environments (such as extreme temperatures, humidity, high salt fog, strong winds, etc.), dynamic load scenarios, and the excessive lateral loads and stresses endured by the cranes during operation.
On this basis, YFM maritime cranes are ensured to safely, reliably, and efficiently perform tasks such as cargo handling, equipment deployment, rescue operations, and offshore engineering support at sea.
Main Application
1. Port/Harbor/Dockyard Cranes
- shore cranes(Shore-to-Ship Cranes): Container Cranes and Unloaders.
2. Ship/vessel Cranes
3. Offshore Cranes: Used in oil and gas platforms or offshore wind platforms.
4. Rescue & Salvage Cranes
- Floating Cranes: Mounted on floating vessels or barges for water-based operations.
Bulk Handling
Grab granular bulk cargo such as grain and coal through grab buckets for transportation.
Container Handling
Handle/transport containers by fixing them with spreaders.
Heavy Lift Handling
Lift heavy machinery that cannot be carried by human power through hooks.
General Cargo Handling
Transfer miscellaneous cargo through special tools such as cloth bags and hanging baskets.
Differences from Land Cranes
- Environmental Adaptability: Maritime cranes must withstand special conditions such as high humidity, salt spray, vibration, and ship swaying.
- Space Constraints: Due to the limited deck space on ships or platforms, the design places greater emphasis on compactness and maximizing the operational range (e.g., articulated arms save over 30% of deck space).
- Safety Standards: They must comply with strict specifications of the IMOand classification societies (such as DNV, BV, RINA, etc.), covering requirements for anti-tipping, fire prevention, explosion protection, etc.
Delivery Scope Of Maritime Cranes
Crane Body:
1. Pedestal as a separate unit: Internal stiffeners for transportation for the pedestal
2. Crane house as a separate unit.
3. Crane boom as a separate unit
5. Main winch as a separate unit
6. Wire rope as a separate unit(Optional)
7. Loose gear and various ladders, platforms, etc
8. Cylinders as separate units
9. Special Tools: Grease Gun
Surface Treatment OF Maritime Cranes
1. External Treatment
A. Pedestal, Crane House, and Boom
- External surfaces are sandblasted to Sa 2.5 standard.
- Apply one coat of Interzinc 52 primer with a dry film thickness of 75 microns.
- Apply a second coat of Intergard 345 intermediate paint with a dry film thickness of 125 microns.
- Apply a third top coat of Interthane 990 with a dry film thickness of 60 microns.
- Top coat color: as specified by the customer.
2. Internal Treatment
A. Pedestal and Crane House
- Internal surfaces are sandblasted to Sa 2.5 standard.
- Apply one coat of Interzinc 52 primer with a dry film thickness of 40 microns.
- Apply a second coat of Intergard 345 intermediate paint with a dry film thickness of 75 microns.
B. Oil Tank (Integrated in Crane House)
- External surfaces are sandblasted to Sa 2.5 standard.
- Apply one coat of Interzinc 52 primer with a dry film thickness of 40 microns.
C. Inner Side of Boom Closed Box
- No treatment is required, as it is a fully enclosed steel box structure.
