Automated cranes in inland yards of large container ports are mainly divided into tire-type container cranes and rail-type container cranes. This type of gantry crane produced by SEVENCRANE yard gantry crane manufacturer is a special machine used for loading, unloading, transporting and stacking containers at container terminals and container transfer stations. RMG is driven by electricity. Because of its energy saving, environmental protection, low cost and low failure rate, it is the preferred yard operation machine for new terminals now and in the future. Orbital gantry cranes are generally larger than tire-type gantry cranes and have more stacking layers. Because the orbital gantry crane travels along the track laid on the site, it can only operate within a certain site range of the track. The orbital gantry crane has strong positioning capabilities and is easier to realize fully automated loading and unloading. It is an ideal machine for automated container terminals. We are one of the CE approved yard gantry crane supplier in China, we have run in crane industry for more than 30 years. If you want to purchase the yard gantry crane, then we can be your reliable chinese supplier yard gantry crane factory.

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.
