Background

Shore bridges, also known as shore container cranes, are equipment used to load and unload containers on container ships on shore. In order to reduce the cost of shipping and circulating goods, more goods are loaded on the ship, the container ship is updated from 2500TEU Panama type container ship to 7000TEU container ship with the fourth generation, fifth generation and sixth generation, so that the large-scale speed of the container ship is accelerated to the current ten thousand-container ship times.

In order to match the upgrading of the container ship, the shore bridge reach is changed. The distance from the original front reach to 35 m, 50 m and 65 m to the maximum distance from the front reach to 80 m. If the active shore bridge can not touch the container far from the side of the wharf, the container can only be adjusted to the head' without any trouble, which wastes time and labor. The quayside usually purchases a shore bridge with larger reach to meet the berthing of a large container ship, but the cost of the new shore bridge is higher, the delivery time of a manufacturer is long, and the like. Therefore, the quayside often excavates the capacity of the active shore bridge, and improves the capacity of the shore bridge for hoisting containers at a farther position by modifying the reach of the active shore bridge.
