Shipyard cranes are the main equipment for manufacturing ships. Currently, crane trolleys generally use rimless wheels and are designed with a guide device (horizontal wheel) added to one side of the track. This structural form reduces the manufacturing deviation and the impact of track gauge changes on the trolley operation under trolley load conditions. Rolling friction replaces sliding friction between the horizontal wheel and the side of the track, and the frictional resistance endured by the operating mechanism is greatly reduced.

The light tire-type container gantry crane for ports can meet the loading and unloading needs of existing cargo types, and has functions such as customs declaration, inspection, foreign trade, and storage. Moreover, its operation efficiency is high and it can take into account the company's subsequent container development. Light tire-type container gantry crane has the following characteristics:

In recent years, with the increasing use of offset rail beam structures (square steel welded rails located inside the box-shaped main beam), the manufacturing requirements have become higher. Let's take this structure as an example to improve it from the manufacturing aspects such as component manufacturing and processing.

Shipyard gantry cranes are referred to as shipyard cranes. Shipyard cranes are mainly installed in shipyards and ports (outdoors) and are used for ship construction and lifting and shipping of large workpieces. It is a special loading and unloading machine for stacking operations in container terminal yards or container cargo yards. It is mainly composed of a lifting mechanism, a trolley traveling mechanism, and a cart traveling mechanism.

The anti-fall device for jacking cylinders in shipyard cranes adopts a spring ejector ball fixation method, which can not only lock the cylinder when the piston rod retracts to prevent the piston rod from falling, but also disengage the ejector beads when the piston rod extends, allowing the cylinder to jack up the tire. Hydraulic gantry crane.

With the rapid development of the economy and the growth of foreign trade, a large amount of heavy equipment needs to be transported from site to site. Shipyard cranes are widely used because of their safety, efficiency, speed, convenience and other advantages, and have become one of the key equipment for material handling automation.
