Simple mobile gantry cranes are used for boarding ladders in port

For a long time, when the port boarding ladder swings out of the dock guardrail, it takes more than 10 people to complete it. It not only has high safety risks and low working efficiency, but also has a very low working efficiency. Flagcrane customizes the simple mobile gantry crane according to the work process of the boarding ladder.

When a 100,000-ton cargo ship docks and unloads, it is necessary to extend the boarding ladder from the dock surface to the stern gangway, and its distance reaches nearly 8m. Even if the boarding ladder is made of lightweight aluminum alloy, its deadweight reaches more than 200kg. The control of the up and down of the ship personnel and the change of the tide level make the boarding ladder frequently operate out of the gangway, which requires frequent and large-scale manpower adjustments, and there are great safety hazards.

Since the first docking of a 100,000-ton cargo ship, the port has gradually entered the normalization of loading and unloading of 100,000-ton ships, and the utilization rate of 8m long ladders has gradually increased. Therefore, the port urgently needs a lifting equipment that can be used to transport the boarding ladder, so a lightweight and flexible "mobile simple gantry crane" is suitable for this occasion.

The "mobile gantry" is made of common steel. The electric hoist is retracted and released by simply pressing a button to control the boarding ladder to be smoothly extended out of the sea and mounted on the gangway, replacing the previous large amount of manual operation with great safety risks. At the same time, the customized boarding ladder pallet truck can easily move the boarding ladder frame to the gantry; the design and production of the simple gantry crane also minimizes the wear of the boarding ladder. The gantry is fastened with a lifting chain in conjunction with a hook and a shackle, replacing the common wire rope fastening, adapting to the relative position change of any position and the ground order, and realizing the fast fastening of the gantry; at the same time, the land side is designed to install 4 chains to provide double insurance for the fastening of the simple gantry crane. At this point, the port boarding ladder can be smoothly, labor-saving, and safely extended out of the sea, and accurately mounted on the gangway.

The application of mobile simple gantry cranes in ports is of great significance to port boarding safety. Flagcrane customizes and designs and produces different types of lifting equipment according to different needs and conditions. If you have any questions, please Contact Us！
