Shipbuilding gantry crane is suitable for shipbuilding operation in shipyard (dock, slipway). It has many operation functions, such as single crane, double-point lifting, three-point lifting, aerial overturning, light load (≤ 50% full load) rapid lifting, low wind speed (≤ 8m / s) and other operation functions. In the overall hoisting of the crane, the main beam hoisting is a key link, with 800t gantry crane Before lifting the main beam to the upper and lower parts of the main beam, the total weight of the trolley should be lifted to the upper and lower parts of the main beam to prevent the trolley from lifting up and down to a total weight of 35t before lifting the main beam to the upper and lower parts of the main beam, and lifting the trolley to the upper and lower parts of the main beam to prevent the trolley from lifting up to 45t and lifting the trolley to the total lifting position of 45t. Therefore, the total weight of main girder is 3204t, and the total lifting weight of two towers is 4000t, which is within the safety factor of 1.25
When the crane is fully loaded, the crane's working span is up to 962.5 m, the crane's working span is up to 962.5 m, and the crane's working load is up to 962.5 M.
It is suitable for shipbuilding operation in shipyard (dock and slipway). It has many operation functions, such as single crane, double-point lifting, three-point lifting, aerial overturning, quick lifting with light load (≤ 50% full load) and fast operation at low wind speed (≤ 8m / s).
Crane is a kind of gantry crane with large lifting capacity, large span, multi-function and high efficiency. It is specially used for large-scale ship block transportation, docking and turnover operation in dock (or slipway).
Main technical features:
1. It has the functions of single crane, lifting crane, air overturning, horizontal micro rotation in the air, etc.
2. There are two types of portal frame: single main beam type and double main beam type for users to choose. In order to reasonably use materials, the main beam adopts variable cross-section optimization design.
3. The rigid leg of portal frame has single column type for Yonghe.
4. The upper trolley is equipped with double main hooks, which are respectively placed under the center of the main beam.
The main and auxiliary hooks are arranged at the bottom of the main beam and two auxiliary hooks are arranged at the center of the main beam.
6. The upper and lower trolleys can cross each other.
All lifting and speed regulating mechanisms are adopted.
8. At the rigid outrigger side, the top surface of the main beam is equipped with a transfer maintenance crane to complete the maintenance of the upper and lower trolley.
9. In order to facilitate the driver and maintenance personnel to get on the plane, a boarding elevator is set in the rigid leg.
10. In order to prevent storm attack, it is equipped with safe and reliable wind proof devices such as rail clamp.
