Davit Crane
A davit crane built for boat and deck operations, with a load capacity of 2.5 to 20 tons and a 360 degree slewing range. It uses a wire rope hoist, corrosion resistant materials for marine exposure, anti sway technology and a variable frequency drive, and can be operated by radio control or fixed push button control.
- Corrosion resistant steel
Product Overview
A davit crane built for boat and deck operations, with a load capacity of 2.5 to 20 tons and a 360 degree slewing range. It uses a wire rope hoist, corrosion resistant materials for marine exposure, anti sway technology and a variable frequency drive, and can be operated by radio control or fixed push button control.
Key Benefits
- Corrosion resistant materials chosen for marine and dockside exposure
- 360 degree slewing covers deck and waterside in one installation
- Anti sway technology steadies loads over water where a swinging load is dangerous
- Variable frequency drive optimises motor performance and power use
- Radio control lets the operator stand clear of the lifting area
Problems It Solves
- Standard industrial cranes corroding quickly in a marine atmosphere
- Loads swinging over water where there is no way to steady them by hand
- Operators forced to stand inside the lifting area to see the load
- Precise positioning needed at the waterline with no fixed reference
Where It Is Used

Compared With The Alternatives
| Pillar jib crane | Same slewing principle, but the davit crane is built for marine exposure and load control over water rather than for a dry workshop floor. |
|---|---|
| Mobile crane at the quayside | A davit crane is permanently installed and always ready; a mobile crane has to be brought in and set up for each lift. |
Use Guide
- Confirm the reach needed from the mounting point to the lifting position over the water
- Specify the coating for the salt exposure at your location
- Use anti sway and slow lifting speed when lifting from a moving surface
- Inspect the wire rope regularly in a marine environment
